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
