The sea is so deep, how did the piers of the Hong Kong Zhuhai Macao Bridge go down?

First of all, it is necessary to hit the bridge pier, the bridge pier must be built on the rock of the seabed, so that it will be more solid, and then the staff of the bridge must detect the seabed, design it in advance, understand the structure of the seabed, find the shallow place, and then each bridge pier will have a bearing cap, and use the caisson method in a deeper place to make a large cylinder of a basketball court, pour concrete on the cylinder, and sink to the bottom under the action of gravity.

First of all, it is necessary to build the cushion cap, so that it can be better built, the place where it needs to be taught to build, enclosed with special materials, and the ground needs to be exposed, so that the operation can be carried out, and this operation is more time-consuming and laborious, but it is safer.

When human beings are building the cross-sea bridge, the construction of the bridge piers requires science and technology, and many people need to work hard. It is also a miracle of human transformation of nature.

The seabed of the Zhuhai-Hong Kong Bridge was built using the immersed tube method. The immersed pipe method is the abbreviation of the prefabricated pipe section sinking method, which is a construction method for underwater construction tunnels, which is to build the submarine tunnel first, seal the two ends and then sink to the bottom of the sea, and finally splice the tunnel one by one on the seabed.
