Hong Kong-Zhuhai-Macao Bridge Island Tunnel Engineering Soft Foundation Improvement Project

Hong Kong-Zhuhai-Macao Bridge Island Tunnel Engineering Soft Foundation Treatment Project

Project Profile

 

Name: East and West Artificial Island Soft Foundation Plastic Drainage Board Installation Project

 

Location: Zhuhai & Hong Kong, Guangdong

Method: Precipitation of large overload ratio

Construction time

West artificial island start time: June 2011; completed: December 2011

East artificial island start time: February 2012; completed: May 2012

In order to withstand the typhoon, the bridge should not be too high, and it must meet more than 4,000 ships every day, in the deep waters of the Lantau Strait near Hong Kong.

Road, the first use of two artificial islands as the foundation for bridge and tunnel conversion, the design of the clever artificial island uses the steel cylinder cofferdam. Inside the steel cylinder

Soft foundation treatment is required in the industrial island, and the installation of the 40-meter-deep PVD faces enormous construction difficulties: operations on isolated islands against typhoons and lightning

The lower drainage board has to pass through the hard layer of 18 m thick medium coarse sand cushion. The friction type inserting machine (patent number: 201510025786.7) has been developed for this purpose.

The process requires that the stitchers has a low center of gravity, high power, deep depth and all the requirements for the frame to rise and fall at any time, and successfully completed the historic mission.
