Siduhe Bridge

Earlier, China became a precedent in the history of the construction of the Super Bridge. The use of a rocket manufacturing bridge to span more than a kilometer of heaven. The bridge built by China in this way can be called the air corridor. What is the reason for China to use the rocket to build this bridge.

Siduhe Bridge

Although the Suduhe Bridge is no longer the first high bridge in China, the difficulty of building this bridge is actually not lower than the first -ranking Beipanjiang Bridge, so where is the difficulty of building this bridge and even forced China to force China to force China You must use a rocket to continue to complete the construction of this bridge?

The Sidu River Bridge during the construction process

This reason is actually very simple. Compared with the Beipan River Bridge, the environment around the construction location of the Suduhe Bridge is quite harsh. The distance between the two mountains is as high as 1365 meters. The area around the area is a very steep cliff, which has caused the construction staff to have a headache: because the terrain around the Sudu River Bridge is too dangerous and harsh, if they do not build a dedicated to this before building the Sidu River Bridge The road, then even tools like excavators don't want to transport them to the bridge pier.

Of course, this is not a big problem for Chinese engineers. Whether it is digging roads or building pier, it is completely within the ability of Chinese engineers. This is basically not a problem for the Chinese engineering and infrastructure system of water bridge, but if you want to build the Sidu River Bridge, the real problem is how to pull the steel cable guidance required for this suspension bridge from a bridge tower to the tower to the tower to the tower to the tower to On the other bridge tower, this task is obviously not simply solved by relying on the way.

Set up the Sudu River Bridge in the main cable rope

Although the guide cable is not as heavy as the main cable of the bridge, it is not something that ordinary people can easily move: if you need to move this kind of heavy steel cable that needs 5 or 10 groups to move to the bottom of the valley, then The use of manpower and machinery to pull it to the other side, the difficulty is not capable of manpower. In addition, the environment around the Sudu River Bridge is not suitable for the helicopter loading. The helicopter of the mission crashed, which caused huge economic losses and casualties.

This is why China uses a rocket guidance technology to launch the guidance of the top steel cables on the top of the Sudu River Bridge to the opposite side of the bridge; When various factors fail, then you only need to drag the steel cable back and tie the new rocket and launch again, and this kind of use of the rocket guidance system in China to throw the steel cable guidance directly to the other side. It has also become one of the optimal solutions that the construction teams who want to find the building suspension bridge in this harsh environment.
