Description

Technical Field

[0001] The invention relates to the technical field of cofferdams, and in particular to a small underwater device capable of rapid splicing, fixing and drainage. Background Art

[0002] There are two types of cofferdams available. One is to use soil, rocks and sandbags to pile up a large earth and rock cofferdam, and then drain the water inside the cofferdam. The other is to use special steel plates and professional piling equipment to drive the steel plates into the foundation to form a steel sheet pile cofferdam.

[0003] The earth-rock cofferdam is mainly made of clay piles to form a large cofferdam. This method requires the construction of a large road for muck trucks, and a large amount of clay needs to be transported out and dumped into the water. Excavators and bulldozers are used to trim and roll the cofferdam to form a drainage cofferdam. The construction speed is slow and the construction period is not less than 20 days. After the construction is completed, muck trucks, excavators and other professional machinery are needed to dismantle the earth-rock cofferdam. The construction cost is huge, generally several times or even dozens of times the cost of repairing or replacing equipment.

[0004] The steel sheet pile cofferdam is made of special steel plates. Professional piling tools are used to splice and squeeze the steel plates into the underwater foundation to form a drainable cofferdam. The construction speed is one-third faster than that of earth-rock cofferdam. This method requires professional piling machinery, and a mechanical road or steel bridge must be built above the cofferdam. Earth-rock foundations can be constructed, but large bedrock or concrete foundations are not suitable. Dismantling also requires professional equipment, and the construction cost is huge, generally several times or even dozens of times the cost of repairing or replacing equipment. Summary of the invention
