Environment-protecting bridge pile foundation construction method for water conservancy construction

Abstract

The invention discloses an environment-protecting bridge pile foundation construction method for water conservancy construction. An environment-protecting bridge pile foundation construction device for water conservancy construction comprises steel pipe piles distributed in a matrix mode, wherein parallel connection pipes are welded to the outer walls of the adjacent steel pipe piles and used forstrengthening the overall firmness between the steel pipe piles; and the steel pipe piles and the parallel connection pipes are arranged beside a constructed foundation in a buried mode, the top endsof the steel pipe piles extend out of the foundation, the top ends of the steel pipe piles are provided with adhered nesting frames in a nested mode, and the plurality of nesting frames are welded tothe lower surface of a main beam. The environment-protecting bridge pile foundation construction method for water conservancy construction has the beneficial effects that the top end of a pipe shell is vibrated through a vibration hammer, and muddy water is squeezed to flow into drain holes and is discharged from the side face of the pipe shell through outlets; and in the pouring process, the pipeshell is filled with concrete through communicating holes, the concrete continuously sinks and is compacted, meanwhile, the muddy water at the bottom of a cover sealing plate is isolated from entering the pipe shell through the cover sealing plate, and sludge drainage is carried out through cooperation between the drain holes and the outlets and water flow, so that the workload of sludge pumpingis reduced, the project completion time is shortened, and the problem that a large amount of energy is undoubtedly needed for pumping the muddy water is solved.

Description

Technical field [0001] The invention relates to the field of bridge pile foundation construction, in particular to an environmentally friendly bridge pile foundation construction method for water conservancy construction. Background technique [0002] A deep foundation composed of piles and pile caps (referred to as caps) or a single pile foundation connected by columns and pile foundations, referred to as pile foundations. If the piles are all buried in the soil, the bottom of the cap and the soil Contact is called low-cap pile foundation; if the upper part of the pile is exposed to the ground and the bottom of the cap is above the ground, it is called high-cap pile foundation. Building pile foundations are usually low-cap pile foundations. In high-rise buildings, pile foundations are widely used. Similarly, pile foundations are often used for support in the erection of bridges. [0003] Pile foundations are widely used in various construction structures in the current constructi...

AI Technical Summary

Problems solved by technology

[0004] The construction of the existing bridge pile foundation is to use the equipment and the casing to extract the mud, and then use the process of concrete pouring. The extracted sludge needs to be treated before it can be discharged. At the same time, the garbage generated during various tasks will seriously pollute the environment. Treatment Undoubtedly, a large amount of energy will be used in such piling mode. When bridges are built in some rivers with slow water flow, shallow water layer and wide water surface, serious energy waste will occur, and it cannot respond to the national call for energy conservation and environmental protection.
