A Construction Technology of Mud Retaining Wall of Underwater Foundation Trench

Abstract

The invention discloses a construction process for mud retaining walls of underwater foundation trenches, which include mud guards and steel pipe piles, each mud guard is installed between two steel pipe piles; the steel pipe piles include structural piles at the lower end, The construction pile at the upper end, the construction pile and the structural pile are connected as a whole, the two sides of the steel pipe pile are welded with angle steel locks, and the two sides of the fender are fixed with H-shaped steel matched with the angle steel locks. The mud plate is installed in the angle steel lock of the steel pipe pile through the H-shaped steel; the construction process includes the following steps: 1) Design the floating operation platform; 2) Drive the steel pipe pile; 3) Install the fender; 4) Move the operation platform 5) Subsequent pile sinking and fender installation. The mud retaining wall of the invention has the advantages of good structural reliability, simple process, high construction efficiency, small safety risk, and low engineering cost.

Description

technical field [0001] The invention relates to a construction technique for mud retaining walls of underwater foundation trenches, belonging to the field of underwater foundation trenches. Background technique [0002] At present, mud retaining walls need to be installed on both sides of the immersed tube foundation groove of the deep and medium channel to block the flow of silt and prevent the mud from affecting the immersed tube foundation groove. The traditional mud retaining wall is a continuous steel sheet pile structure. When this structure is used, there are The following disadvantages: [0003] 1) The lock of the steel sheet pile is tight, the construction is difficult to control, the construction efficiency is low, and it is difficult to dismantle underwater. [0004] 2) A large number of diving operations are required, and the safety risk is high. [0005] 2) The investment of steel sheet piles is large, and the project cost is high.
