Method for building cross-sea bridges

Abstract

The invention discloses a method for building cross-sea bridges. The method for building the cross-sea bridges comprises the steps that S1, a first mainland and a second mainland are included, a sea area is defined between the first mainland and the second mainland, an artificial island is built in the sea area, and the cross-sea bridges are built between the artificial island and the first mainland as well as between the artificial island and the second mainland; and S2, for a large water area, two or more artificial islands can be built according to the distance, and the cross-sea bridges are built between the artificial islands as well as between the artificial islands and the mainlands. According to the method, the artificial islands are used as media for connecting the water areas, specifically, one or more artificial islands are built in the water areas, then the cross-sea bridges are built between the artificial islands and the mainlands or between the artificial islands, and finally traffic between the two mainlands with a large water area formed therebetween is achieved. According to the method, the building cycle is short, cost is low relatively, the technologies are mature, the economic benefit is good, and the method is convenient to popularize.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a method for building a sea-crossing bridge. Background technique [0002] At present, the way to connect across waters in the world is to build underwater tunnels or erect bridges, such as the English Channel Tunnel and the Great Channel Tunnel in Denmark. The latter, such as the Pontchartrain Lake Bridge, is located on Lake Pontchartrain in Louisiana, United States, connecting New Orleans and Mandeville, with a total length of 38.4 kilometers and is the world's longest spanning water bridge. [0003] On June 30, 2011, Qingdao Jiaozhou Bay Bridge was officially opened to traffic. The bridge is 36.48 kilometers long. It is the second longest bridge in the world after the Pontchartrain Lake Bridge in the United States. Qingdao Jiaozhou Bay Bridge is located in Qingdao City, Shandong Province, China. [0004] Known as the "Golden Waterway", the Qiongzhou Strait is o...

AI Technical Summary

Problems solved by technology

But if the distance of the water area is more than 40 kilometers, it is very difficult for the current human technology to do it

If the method of building a subsea tunnel is adopted, the project cost will be at least twice that of the bridge, and the period will be longer. The geological conditions of the subsea tunnel are complex and changeable, and the construction difficulty and risk are huge.
