Coordinates China ｜ 30,000 tons of stations "moving" exquisite interpretation of "translation of accuracy"

Xiaoxin said

In the past ten years, a series of heavy weapons and super engineering created by central enterprises have engraved new coordinates of national development from different dimensions. On September 12th, the online theme promotion of "our ten years@coordinates China" was officially launched. Over the major achievements of representative infrastructure construction and scientific and technological innovation, it shows the courage, courage and wisdom of challenging the limits and challenging the limit.

The main station building of Xiamen Houxi Coach Station is 162 meters long, 33.6 meters wide, 30,000 tons, and 288.24 meters. Rotate the world record. The transition rotation arc reaches 90 degrees, and the accuracy of the taxi is controlled within 2 mm, which is the first time in the industry. This time the "Qiankun movement" opened up the construction channel of the Fuxia high -speed rail. While saving construction investment, it also avoided a large number of construction waste, dust and noise caused by demolition and reconstruction. A vivid footnote. Today, Xiaoxin brings you the eighth issue of the "coordinate China" series theme films, and China's accuracy of "Transfer".

Fujian Xiamen Houxi Coach Passenger Station Translation Project

At 288.24 meters of translation distance

Certified by Guinness World Records as

"Buildings have the longest arc as a whole"

The construction area of ​​the main station house is 22,800 square meters

Total weight of 3.018 million tons

Equivalent to 2.5 Arc de Triomphe

Realize 90 degrees rotation

Chinese architects

Will alternate step -by -step push and translation technology

The first time is applied to domestic translation engineering

Created the largest translation area in China

The heaviest load and the farthest distance

The most transit of single building

Part1

Why transit?

Xiamen is one of the earliest open economic zones in China

Is a tourist destination for the southeast coast of China

Xiamen in early 2019

Facing a difficult problem

Transportation hub outside the island

Houxi Coach Passenger Terminal

Because of the location

Re -coincide with the Fuxia Zhanggao Railway route

Facing the problem of demolition

To give way to high -speed rail

Mental argumentation of experts

It must rotate 90 degrees arc

Transfer to a new position

This is the best choice to avoid demolition

Part2

How difficult is the overall translation?

The overall migration project of the building

It has always been a difficult point in the field of infrastructure

This time passenger station translation is huge due to its huge volume

There is no precedent for success in the world

Theoretical calculation

Translation has the possibility of success

But overall migration

Need to solve two major problems

The first is to cut the pillar of the building

This process is also called broken base

If in the process of broken base

The construction is a little careless

It may cause

The collapse of the building that loses the foundation

Another important difficulty

It is in the process of translation

Accuracy control

Such a complicated architectural structure

Once unevenly suffered

Or pushing the thrust beyond the range of building tolerance

It is very likely to cause building damage

Part3

How to achieve accurate translation?

In order to ensure that the translation is successfully completed

The engineer finally locked the eyes

"Alternate step -by -step push translation" technology

The principle is through

Installation of steps at the bottom of the building

Make the building from the track stagnation

Unexpected settlement and other issues

There is no way to adjust the direction by yourself without angle restrictions

Multi -angle

Precise alternately walking forward

Just like the building has "foot"

Let the building "walk" along the track to the new site

The engineer chose after calculating

The second floor with a more stable support structure

Perform tower cutting

Pour concrete between columns

Form a solid mesh tray

The main building stairs break away from the foundation

It is taken down like a block

At the same time

Dig out a large foundation pit

Laying 26 arc concrete tracks

At the bottom of the main station

Installed 532 steps to perform the runner

How to ensure 532

The pace of a walking device is consistent?

Engineers will

603 sensors are placed to

The key position of each walkler

It's like 603 eyes

Watching the walking information of each walking device

Real -time feedback, real -time monitoring

532 Top Push of the Walker

Once the error exceeds 2 mm

The system will automatically call the police

Suspension

From 9 o'clock to 12 o'clock

30,000 -ton long -distance passenger station main station room

At a rate of 7.5 meters per day

Control of accuracy of not over 2 mm per step

Lotten 38 days

Cumulative 288 meters

Realized the perfect rotation of 90 degrees

Central enterprise engineer

With the original intention of craftsmanship, and struggling to take the mission

Pour the new image of China with the most reliable hands

Help to improve the "construction of China"

Brand reputation and global influence

Do you want to know which new era coordinates?

The next issue is equally wonderful!
