The "vertical flying sky port" of China Shenzhou, the sea of stars starts from here!

Long March No. 2 F Rocket

In the Jiuquan Satellite Launch Center

It will carry Shenzhou No. 14 manned spacecraft

And three Chinese astronauts sent to space

Before sailing

There is also a "ultra -short trip" in the long two F rocket:

Pass 1.5 kilometers long track

Reach from the technology zone to the launch tower

And the starting point of this "ultra -short trip"

It is a vertical assembly test plant

The huge factory building of 93 meters high

It is the core building of the entire Jiuquan Launch Center

Here, the Shenzhou spacecraft and the escape tower are connected to the rocket

Complete the combination of boats, arrows, and towers

And after several months of testing

To ensure the safe and smooth journey of its space

Why is a giant plant?

What challenges will be encountered in building such a factory?

Today, Xiaoxin reveals the secret for you!

01

"Standing" Chinese Shenzhou

Speaking of vertical assembly plant

The first keyword is "vertical"

Before 1997, the transfer of the rocket in my country

Most of them are "lying down"

Horizontal testing, hierarchical transportation

Rockets' core, rectified hood and other components

Divided into segments to the launch area

Perform, docking and testing on the launch tower

Now

More Chinese Shenzhou is a "standing" transition

Behind "Standing" is "three vertical"

—— Vertical assembly, vertical test and vertical transfer

The "San Dynamic Model" will move forward the focus of work forward

The main tests are solved in the technology zone

Reduce the pressure of the launch area

The core of the "three vertical model"

It lies in the vertical assembly testing plant

Rockets complete assembly, docking and testing in the plant

It can reduce outdoor wind sand, rain, rain and snow, etc.

High climatic impact

Improve reliability

The launch area no longer needs to be repeatedly tested

Shorten the residence time of the rocket in the launch area

The launch efficiency is improved

According to statistics, the era of horizontal transition

Rockets need to occupy the launch station for about 14 days

In the three vertical mode

Time shortened to three or five days

The segmentation process can also be decentralized

The launch area that can be "reduced"

Be able to focus on the launch

High -difficult buildings on Gobi Beach

Jiuquan Satellite Launch Center

Vertical assembly test plant

Construction by the Eighth Bureau of China Construction China Construction

Under the "Three Vertical Models"

my country's first vertical flying sky port

Build on Gobi Beach

A 38 -storey behematic building

And there must be no floor partition in the middle

There are no precedents in the history of Chinese and Asian architecture

To accommodate the huge body

And its complex assembly needs

It requires tall and hollow

But for the builder

Let a thickness 15 meters

The plane area is 3000 square meters

The box type weighing 14,000 tons is steadily standing locally

It is also a technical problem

The builders finally adopted the concrete framework

Joint support scheme with steel truss

Unlike all steel structure commonly used in developed countries in Europe and the United States

This set of innovative technology saves 300 tons of steel

While cost -saving

It is still refractory, insulation, sound insulation, and earthquake resistance

Wait for the strength

Jiuquan also has a rocket's exclusive giant door

The steel gate alone is 80 meters high, weighs 240 tons

To ensure accurate positioning of the door

Automatic lock is firm and reliable

The builders fought for 120 days in a row

Finally completed this giant door

Jiuquan in the windy weather

And Hainan Wenchang

Nearly 100 meters of tall factories

You also need to deal with the pressure of wind load

The reinforced concrete structure can effectively reduce the deformation of the frame

July 2014

Level 18.4 Typhoon "Weimax" landed in Wenchang

There is no decoration test plant

03

"Double Factory" helps the journey of space

As the youngest space launch base in my country

Wenchang has two vertical assembly test factories

It will be used to launch the Long March 5 and the Long March VII laid -off rocket

Long March 5 vertical assembly test plant

Constructed by the Eighth Bureau of China Construction

Its height reached 99.4 meters, surpassing Jiuquan

Become the highest single -story factory in China

There is a steel frame activity platform on both sides of the hall of the plant

It is the core facility of vertical assembly testing plant

In Wenchang's factory building

These platforms can also be up and down up and down

Technicians can be based on work needs

Adjust the platform location

Facing the rocket directly for measuring

In order to let the tens of meters stand out of Hong Kong

The builders also designed

The largest steel door in Asia, 81 meters high

It is 5 fans from left and right

Laureate of steel truss and iron door weighing 30 tons

Add giant door shaft and hydraulic equipment

The total weight of this set of door reaches 784 tons

Nearly 4 empty Boeing 747 aircraft

Shenzhou 12 ship arrow combination is transferring to Xinhua News Agency, a Xinhua News Agency of the launch area

Building a Baying Dream of the Small Port

A set of time data

You can perceive for half a century

"China Acceleration" -

In 1970, the "first fly" of the Long March 1 laid -up rocket

As of December 10, 2021

The Long March series of rockets launched 400 times

The first three "100 times"

Use 37, 7, and a half years, and 4 years, respectively

And the recent "100 times"

It only took 33 months

Innovation of launch technology

Support China faster and set sail towards farther

This is also the prelude to the rocket to the deep space

——Moly subtle, but so great

Building a spouse, Yuan Qianqiu Meng

Except for Jiuquan Satellite Launch Center

In Wenchang, Taiyuan, Tianjin ...

Chinese architecture has participated in construction

National 3/4 satellite launch center

The builders are carved with architecture

Footprints of dreaming space

Help China from the aerospace country

Towards the aerospace power

Next

Walk in with Xiaoxin

The hand -drawn long roll of the builder

See the original intention and ingenuity of the central enterprise builders

Dream of a dream
