【China's Mega Projects 3 CHINA Revealed】超级工程Ⅲ：纵横中国 EP3

[Music] ah [Music] [Music] so [Music] [Music] china is the world's second largest economy along with a history of rapid growth has come one of the most developed transport networks in the world it has the world's largest highway network carrying 80 million tons of freight every day [Music] it has the world's largest high-speed rail network that connects hundreds of cities as well as a huge air transport system with 227 airports 7 out of 10 of the world's largest ports are on china's coasts this huge transport system is the backbone of the chinese economy but progress never sleeps [Music] the network continues to develop night and day quantitatively and qualitatively meeting the challenge of getting people and goods around the nation okay the duggar county in suchwan province is home to the world's largest printing house of tibetan scriptures they have 320 000 printing blocks accumulated over the last three centuries the printing house reproduces 70 percent of the world's tibetan classics covering tibetan medicine history and culture which are delivered to all parts of china today master dugar is dispatching a number of these classics to kung ding [Music] [Music] foreign [Music] dhaka is nearly 600 kilometers from kangdik a 24-hour ride the biggest obstacle in route is the chola mountains that rise to 6168 meters above sea level for centuries it has been a major barrier between the tibetan region and the rest of china [Music] the narrow dirt road that connects this part of north sutuan to tibet was built over 60 years ago it snowed over for all but two months of the year a breakdown can cause a traffic jam which lasts for days it is notorious to drivers as the most dangerous road in china this struggle will soon be over for five years a huge project has been underway beneath the mountains the tola mountain tunnel will be the world's longest and highest road tunnel foreign foreign the harsh environment puts every worker under huge pressure the project is entering the final stage the tunnel will be finished in a month's time thanks to the efforts of thousands over the past five years it will then take just 10 minutes to cross the mountains and to do so in safety while sheltered from the [Music] weather [Music] today huang chitin is going to be the first non-engineer to drive through the tunnel [Music] his car is equipped with a 360 degree laser radar continuous image capturing camera and a positioning data acquisition system this allows him to collect road information in real time as he drives along [Music] also has to cope with altitude sickness as he drives through the world's longest high altitude tunnel [Music] in under 20 minutes all the mapping information from the tunnel has been collected huang tijin will continue mapping along the highways collecting data that has never been recorded before two thousand seven hundred kilometers away in beijing once data from the chola mountains has been received an hour later an electronic map outlines the new road [Music] when it opens to traffic this new map will be sent to every mobile phone user through the internet in less than a second [Music] china has the planet's largest highway network over 200 million vehicles carry 15 billion passengers and 33.6 billion tons of cargo a year [Music] and the network is still expanding other bold projects like the chola mountain tunnel will open to traffic china's highways now extend to every corner of the country for lu xujet the highways are key to his family's livelihood yunnan's waning county has a uniquely mild climate that allows it to produce the earliest citrus harvest in china [Music] however the fruit only remains in peak condition for a week before the highways open the fruit could only be sold in surrounding cities within a few hundred kilometers from whining [Music] now with the national highways network lu xuji is able to travel across the country in a couple of days taking the fresh flavors of yunnan to north and northeast china foreign [Music] [Music] using satellite positioning can pick the quickest route to his destination [Music] [Music] [Music] [Music] to deliver his cargo a fresh fruit to beijing two thousand seven hundred kilometers away and sell it at good prices lu xuji has to drive overnight the highways at night are rarely quiet many items be they fresh fruit and vegetables or courier packages need to reach the city before it wakes up in the morning every 24 hours more than 20 million trucks like loose run across this huge highway network day and night they carry almost 85 million tons of cargo which accounts for nearly 80 percent of china's total freight volume [Music] the network now spreads to 4.69 million kilometers of that 130 000 kilometers our freeway the longest in the world china's highway network has become a huge engine to promote its social development but you can find that too many vehicles running empty on the road eating away the advantages of highway transportation about 40 percent of the trucks in china run unloaded which pushes up the cost of freight transportation and leads to a huge waste of energy the city of chengdu is an important transport hub in southwest china in the north of the city one smallish gas station can claim to be the most profitable gas station in china it serves over 2 000 trucks every day it takes over 300 tons of fuel oil to meet the daily demand [Music] [Music] [Music] the building on the other side of the wall is why trucks gather here the freight market opens at eight in the morning the trading hall of chengdu logistics port is packed with more than a thousand truck drivers speaking a multitude of different dialects [Music] people used to find it very hard to find the best deal today the situation is already changing more and more people just start with a search on their mobile phones new technology is revolutionizing the way the transport system works [Music] the technology has swiftly shown its appeal to drivers when a truck enters the gate of the highway harbor the vehicle's information will be sent to the back office system the system automatically matches requirements and details of the trucks with the orders for delivery thus goods are matched to suitably qualified trucks and their drivers meaning that each day over 2 000 trucks no longer run empty back out of the logistics center [Music] today more and more digital highway ports are being built across china the highway network's efficiency is being continuously optimized through the use of big data technology in the future every delivery will be more efficient with decreasing energy consumption per unit delivered however while highway transportation has great advantages it also has some inherent disadvantages [Music] is an inland city in western china with a modest population of about 3 million one of its main claims to fame is that it produces diesel locomotives for 24 countries around the world for a city so far from the sea it is a significant challenge to be able to deliver its locomotives to customers who may well be on the opposite side of the globe [Music] 200 kilometers away in ibin city the jinsha and minjang rivers converge into the yangtze river as the longest river in china the yangtze has been a key communications corridor for thousands of years [Music] the great river leads all the way deep from inland china to the pacific ocean that the cost of water transportation is 1 15 of that of highway transportation is an advantage and for extremely heavy goods water transport is irreplaceable a first batch of nine locomotives made for argentina has been assembled they will travel down river to the port of shanghai 2 800 kilometers away then in a couple of weeks time they will be transferred to a sea-going freighter and taken across the pacific it is hoped that these first nine locomotives will lead to the opening up of new markets in the americas highway transportation of these locomotives is very expensive and poses many problems with height and weight limits with water transportation these problems dissolve away the locomotives from zuyung arrive at port [Music] workers hurry to hoist them onto the freighter after a busy night all nine locomotives have been safely stoned [Music] the advantages of water transportation for large cargos are very obvious if not subject to the limitations of geography the arid west of china has an abundance of coal in 2016 china's coal production reached 3.36 billion tons which accounts for more than half of the national energy supply [Music] but most of this energy is needed in the east thousands of kilometers from where it is mined to get it there is the most intricate of chinese puzzles the 594 kilometer railway is one of the busiest in china every day 226 trains run along it in pairs it is like a man-made canal a main artery for china's energy transport province is the starting point of this artery of coal [Music] stocks from western china gather here before being transported to east along this iron canal [Music] 216 wagons are marshaled into a three kilometer long train [Music] 9600 kw electric locomotives to get it moving [Music] then comes the really tricky bit the railway east of shenzhen drops in elevation of more than 1 500 meters the heavily loaded wagons travel downhill through tunnels and bends the huge momentum they acquire poses a major threat to the safety of train if the 216 wagons fail to break correctly and in sequence on a bend in the track the consequences will be catastrophic the secret to solving the problem lies here every day cho jun director of technology checks the 4g transmitter stations along the shukuang railway it's a world first in the application of this technology to heavy haul trains the two locomotives are 1.5 kilometers apart from each other but they have to be precisely controlled to ensure their synchronization a tenth of a second lag could cause a major accident [Music] in order to ensure full 4g coverage there are 260 transmitters along the length of the line sending a continuous stream of data 24 7. this advanced signaling technology is the key to ensuring the safe operation of these super long coal trains it allows synchronized control over the two electric locomotives set 1.5 kilometers apart all in a day's work a great performance to ensure there is no drama [Music] face recognition technology is one of china's leading edge developments based on image recognition and big data it can quickly lock on to target persons being searched for engineers in the monitoring hall of the gui young public security bureau are commissioning a new face recognition and monitoring system [Music] 800 kilometers away tao tao boards a train from guangzhou to gwayong he needed to get to gweiyong this afternoon to direct a crucial part of the commissioning work sao tells company develops and provides facial recognition systems this year it decided to move its headquarters to guayyong due to the rapid development of communications in guizhou province huizhou is the only province in china that is entirely mountainous while this makes for a spectacular environment the province has been equally notorious for its poor communications which have seriously impeded economic development [Music] guangzhou is the capital of china's powerhouse manufacturing province guangdong in the past it would take took 22 hours to get to weiyong by train now the journey time is just four and a half hours thanks to a new high-speed line connecting the two cities [Music] makes it for his appointment every city in china now presses for its own connection to the national high-speed rail network besides the convenience the economic and development opportunities this brings makes a compelling argument as of 2017 china has 22 000 kilometers of high-speed rail lines in full operation 60 of world total it has cut travel times between the great conurbations from days to hours and given rise to a flourishing economic circle around each [Music] and the argentina bound locos have arrived at the three gorgeous dam beginning in 1994 a huge investment and 12 years of work saw the building of the world's largest dam completed besides being designed to control flooding downstream and to aid consistent navigation the hydroelectric plant now generates nearly 100 terawatt hours of electricity supplying nine provinces and two cities [Music] the dam has raised the water level in the upper yangtze by 113 meters which has submerged many dangerous shoals and shallows allowing larger vessels to make passage [Music] thereby the traffic on the river at the dam is now 10 times what was planned for the world's third longest river is now the world's busiest inland waterway the huge upgrade in capacity poses a major challenge no easy job for guo yen to coordinate so many ships through the dam she must rely on the set of five huge ship locks that she manages this is the world's largest inland ship lock 1 607 meters long divided into five chambers with the capacity to take a maximum size vessel of 10 000 tons up to 12 3 000 ton cargo ships can transit the dam in each direction at the same time with the huge fall of 113 meters transit time is four to five hours and longer when there is a backlog of vessels the waiting time can be problematic for pleasure boats and emergency vessels that need to go through the dam quickly [Music] to deal with this the chinese engineers have built the world's largest ship lift it can handle vessels of up to 3 000 tons and take them through 113 meter fall in 10 minutes to achieve this speed the chinese engineers decided to use a climbing of gear rack system aided by gravity the huge rack rolls up and down lifting and dropping cargo in the 200 meter long super elevator [Music] the use of the gravity counterweights greatly reduces energy consumption the shiplift along with the two sets of locks one for upstream one for down have greatly increased the transport capacity on the river the yangtze river tightly connects the 11 provinces it passes through and forms a key economic corridor across the country the argentina bound locomotives pass through the three gorges [Music] they'll continue on down river for another 10 days before reaching the yangtze delta where they can be loaded onto an ocean-going freighter for their final destination for those that don't want to spend days on the water air is the answer beijing capital international airport is the second busiest airport around the world in 2016 it saw a throughput of close to 95 million passengers flight delays have become endemic with around 400 flights each day having to be postponed [Music] the solution is even greater capacity [Music] [Music] in the south of beijing thousands of construction workers are tackling the flight delay problem they are building a whole new super airport to serve the city the huge steel starfish-like structure means that passengers will never have to go more than 600 meters to reach their boarding gate the large central hall without columns is designed to maximize the public space the innovative design brings its own challenges for the builders leo yuen faye climbs 20 stories to the roof every day he is totally familiar with this huge structure [Applause] foreign however the purpose of the building is not to outdo beijing's olympic stadium to meet the demands of 70 million passengers per year the design of the new airport must take into account many other factors [Music] the roof composed of 12 300 spherical nodes and over 60 000 bars is designed to have a natural curving appearance each junction between the beams and their connecting spheres is supported by a series of three-dimensional locking points as the steel roof frames are completed attention turns to more of the internal core support points it will take eight workers to maneuver this 15 ton curved tube into place it is one of the final piece in the sixty thousand piece puzzle on the other side of the terminal building the construction of the four runways carries on a pace the new airport is intended to handle 620 000 flights per year this will put huge stress on the runway's surfaces and what lies [Music] underneath [Music] the engineers have developed a new system for compacting the subsoil the novelty lies less in the method of compacting than in the tracking and calculation of the ground covered and that which remains [Music] beijing the super city is awaiting the completion of its new airport it is expected to start handling traffic in 2019 the time pressure is on china has the world's second largest air transport market and it is one that's still growing at a rate of 10 per year there are 3 000 civil aircraft flying in china and this number is expected to grow to meet the demand china is seeking to build some of its own passenger aircraft the c919 is undergoing testing in pudong shanghai [Music] built to the latest international standards it will be china's independently developed large passenger aircraft and will have an important role in the country's future aviation market [Music] the first successful flight test was three months ago but there are still years of strict testing in accordance with international airworthiness standards [Music] saijuan has 11 years experience in civil aviation and is the c919 leading test pilot today taiwan is working with the engineers on simulating emergency situation that might occur in flight the computer program simulates an aerial close encounter while the aircraft is banking taiwan must make a quick evasive maneuver and steer the aircraft to safety heck heck there will be hundreds of tests done on this simulator but for typhoon the real work is done in the air to complete the airborne tests the first requirement is an aircraft spec for the job young from the flight test center's test engineering department is installing the complex test sensors in another c919 the bear cabin is totally given over to the test equipment b thousands of sensors have been designed and carefully installed on the plane they will give the engineers immediate data throughout the to flight all the airworthiness tests they need to modify at least six c919s like this in all the aircraft we'll make nearly 3 000 test flights [Music] [Music] the fuel consumption of large passenger aircraft manufactured by china is expected to reduce by 15 given its advantages china has received orders for over 700 c919s the c919 can be expected to provide a strong alternative for the future global aviation market after a two-week voyage the freighter carrying the argentina-bound locomotives has reached shanghai one of the many ports on china's east coast the shanghai port with a throughput of 37 million containers is the biggest [Music] northwest of the existing port a new wharf is being run through its operational paces in a month's time the wharf will see its first ship it will then become the largest fully automated wharf as recorded anywhere in the world wang yen and his team have been preparing for four years for this important moment before that they still have two important tests to carry out [Music] as the commissioning date is approaching huangyan's team must make another round of tests to make sure the ghost dwarf is ready for action everything is controlled by computers they will automatically operate and work with each other to move the containers [Music] 130 automatic guided vehicles or agvs for short will move the containers around the wharf they have to avoid not just collisions but even the slightest scratch to test the reliability of the control system the engineers have arranged a special test for the agvs they are programmed to drive in straight lines and round bends within very narrow tolerances the agvs must control their direction in accordance with the driving conditions to turn smoothly [Music] with that dealt with another key is in the offing the 130 agvs are electric powered to minimize emissions and noise pollution [Music] but to ensure the round-the-clock operation of these vehicles that weigh many tons the reliability of their power supply is essentially [Music] the staff in the battery replacement station are carefully observing the process of automatic battery replacement on an agv this is the only agv automatic battery replacement station in asia it takes just six minutes to replace the [Music] battery [Music] by the end of the year youngshan port's automated wharf will usher in the world's super freighters and shanghai port's container throughput will touch 10 of the entire world total [Music] [Applause] glass curtain walls are being installed in beijing's new airport the main building is about to be completed [Music] 40 meters below the height of the new roof the construction of another super traffic system has also entered a critical stage foreign the engineers are carrying out surveying work before laying the tracks for a railway system composed of five lines and 16 platforms it is equivalent to the central station of a large city it will also house the world's first high-speed railway station beneath an airport terminal it allows passengers to transfer freely quickly and conveniently among multiple transport systems but there is a problem in this ingenious plan uh [Music] [Music] [Music] the problem is to be solved by shock insulation technology [Music] 1152 shock insulators will quietly support the huge terminal building [Music] multiple means of transportation are neatly integrated to give play to their respective advantages [Music] from point-to-point road traffic to water transportation for large cargos from high-speed rail to the aviation of the future new technology is allowing each means of transport to be cleaner more efficient and handle ever greater demands for their use [Music] china is truly being transported into a whole new era
