A mobile floating body and its mobile mud suction construction method

Abstract

The invention provides a moving type floating body and a moving type mud suction construction method adopting the moving type floating body, and belongs to the technical field of construction in a reclamation dam. The moving type floating body and the moving type mud suction construction method have the beneficial effects that 1, according to the moving type mud construction method, the continuous operation can be realized, the position conversion time of a mud sucking machine is reduced, and the work efficiency is improved; 2, according to the moving type mud suction construction method, an overwater operation platform is provided for operators, and the construction is safer; 3, the mud suction covering range of the moving type mud suction construction method is more comprehensive, silt in the reclamation dam can be more effectively sucked out, and the bottom sealing quality is ensured; 4, through the moving type mud suction construction method, the mud suction work in a narrow space of the reclamation dam can be realized, a hole drilling platform is enabled to be installed in advance, and the construction period is shortened; 5, according to the moving type mud suction construction method, the whole-process assistance by a crane in the mud suction process is not needed, machinery cost is reduced, and the construction cost is low.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a mobile floating body and a mobile mud suction construction method using the same. Background technique [0002] At present, the commonly used method for clearing the foundation in the cofferdam in the water of bridges is to use the floating hanging dredge suction machine in the water to suck the mud in the cofferdam, and adjust the range of mud suction by swinging the hook. This mud suction method has the following disadvantages: [0003] 1. Frequent shifting of mud suction position, long construction time and low efficiency; [0004] 2. When the suction dredger is disassembled and its position is changed, there is no working platform on the water, so the safety risk is great; [0005] 3. It is easy to be limited by the operating space, the mud suction coverage is not comprehensive, and the quality of the back cover is difficult to guarantee; [0006] ...

AI Technical Summary

Problems solved by technology

[0003] 1. Frequent shifting of mud suction position, long construction time and low efficiency;

[0004] 2. When the suction dredger is disassembled and its position is changed, there is no working platform on the water, so the safety risk is great;

[0005] 3. It is easy to be limited by the operating space, the mud suction coverage is not comprehensive, and the quality of the back cover is difficult to guarantee;

[0006] 4. Limited by the operating space, it cannot work synchronously with the drilling platform, and the construction period is long;

[0007] 5. Floating cranes are required to assist in the whole process, which leads to high mechanical costs and high construction costs
