Author:State -owned Assets Xiaoxin Time:2022.06.28
Recently, infrastructure central enterprises have continued to work hard
In the past few days
A large number of major projects in the transportation field shocked
Follow Xiaoxin together
Enter the "first scene" of the Super Engineering!
Zhongguo Road
01
my country's first desert zero -carbon highway completed
June 2nd
PetroChina Tarim Oilfield
Desert Highway Zero Carbon Demonstration Project
Build and put into operation in the Taklama -Gang Desert
The newly -built 86 photovoltaic power station
Passion in ecological protection forest belt
Vegetables along the Tarim Desert Highway
Say goodbye to the history of irrigation of diesel engines
Realize zero carbon emissions across the road
Become my country's first zero -carbon desert road
Tarim Desert Highway Photovoltaic Power Station
The scale of the decoration machine is 3540 kilowatts
Annual power generation is 3.62 million kWh
The generated power can meet the road along the highway
436 kilometers of ecological protective daily irrigation need
According to calculations, ecological protective forests
About 20,000 tons of carbon dioxide can be absorbed every year
Negative carbon parts can neutralize carbon emissions of past vehicles
For my country's desert governance and desert road operation and maintenance
Provided "Tarim Project"
02
The world's longest mileage desert road is about to open to traffic
On June 10, the investment and construction of China Communications Construction
Xinjiang Wuwei Highway Pack PPP Project
Line S254 Captain Piez to the Midnium Highway
Through the payment of work and acceptance, it will be opened to traffic at the end of the month
Xinjiang will add a new highway through the Taklama -Gang Desert
Wei Li to the last highway
Cross the hinterland of the Taklama Ganan Desert
The total length is about 334 kilometers
Among them, the desert section 307 kilometers
It is the longest mileage in the world,
The widest distribution of flow dunes and the worst construction conditions, the worst construction conditions,
The most difficult desert road
Since starting in October 2017
Highway builders overcome the waterless, non -electricity, no signal,
There is no way to do unmanned smoke
Push 32 Takahashan Mountains
Fill in 28 hill depression
Severe key technical difficulties in the establishment of windy sand roads in the desert area
After the project is completed and opened to traffic
It will make the driving time from the end to Korla
Shorten from 13 hours to 6 hours
It can effectively improve the distance between the local people's travel,
Life cost and difficult to sell agricultural products
This route will be oil and gas in the future
Exploration, development, transportation, etc. provide strong support
Further promote the economic and social development of the region in southern Xinjiang
Zhongguo Bridge
03
The world's first three -tower four -span double -layer steel truss suspension bridge is opened to traffic
On May 27, China Communications Group participated in construction
The world's first three towers, four spans double -layer steel truss suspension bridges
The north exit bridge of the Minjiang River in Wenzhou is completed and opened to traffic
Minjiang North Exit Bridge
It is currently my country and even the world
The most technical difficulty, the construction process
One of the most complicated bridges
The total length of the north exit bridge project of Minjiang River is 7913 meters
Using "two bridges" design
The upper layer is Yongguan High Speed
The lower floor is the National Highway G228 Nanjin Highway
Bridge can provide
The ability of 107,000 vehicles per day
There are two main cables in the bridge
Each main cable is composed of 169 cable stocks, 2300 meters long
About 1.5 "Liaoning" aircraft carrier can be lifted up
The total length of the steel wire of the two main cables
Can add up to the earth 2 laps
During the construction of the bridge, the project team mastered
Strong typhoon zone, three pagodas, four cross -suspension bridges
The upper structure construction and control set technology,
Strong tension Hekou land Shenjing well construction complete set of technologies and other achievements
Provide experience for the construction of the same type of bridge construction
04
The world's first high -speed rail and highway flat layer settled on the cable bridge smoothly combined with dragons
May 31st
Consissed by the China Railway Bridge Bureau
The world's first high -speed rail and highway flat layer layer layer
Yibin Lingang Public Railway Double Yangtze River Bridge goes well
Bridge bridge deck 63.9 meters wide
The middle 4 line is a high -speed rail of 300 km/h
Both sides are two -way 6 -lane cities express road
The distance between the railway and the highway on the bridge is only 2.8 meters
To prevent the strong airflow when the train is driving
Drive road driving safety
The design team develops the first case in the country
Anti -glare, noise reduction, reducing pneumatic impact
Comprehensive protection barrier of public rail parallel segment
Guarantee public railway parallel operation safety
The public iron same floor scheme can reduce the length of the road to the bridge
Save project investment and maximize carbon emission reduction
Greatly reduce the cost and difficulty of bridge maintenance
Promote the ecological barrier of the upper reaches of the Yangtze River
China Tunnel
05
The main structure of the main structure of the lake under construction in China under construction
June 8th, Taihu West Bank
Zhushan Lake Tunnel, built by China Railway 16th Bureau Group
The first plate of the bottom plate starts to pour
It marks the longest trunk road tunnel under construction in China
The main structure of the main structure is fully expanded
The total length of the Zhushan Lake Tunnel is 7.81 kilometers
Single -section bottom plate is poured about 1210 cubic meters to 2244 cubic meters of concrete
It belongs to "oversized concrete"
The bottom plate of the land segment of this time
The total pouring area is 1100 square meters
Equivalent to 3 basketball court size
Project technical team implements "combined well precipitation technology"
Effectively solve the problem of pink sand geology and water seepage
Use "ultra -deep mud local curing technology"
Machinery and equipment can walk on the sludge after curing
Save a lot of time
