Abstract

The invention provides a steel sheet pile cofferdam water stop belt. The water stop belt comprises an elastic outer casing and magnetic columns. The elastic outer casing is provided with a hollow portion, and the plurality of the magnetic columns are disposed in the hollow portion. A water stopping process is further provided for the water stop of a steel sheet pile cofferdam. The steel sheet pilecofferdam water stop belt is embedded in a lock gap of the adjacent steel sheet piles to prevent water outside the cofferdam from permeating the cofferdam. The water stop belt has advantage that a prefabricated belt material replaces the original mixture of multiple materials, the pretreatment steps are reduced, and the installation time is saved; moreover, due to the built-in magnetic columns ofthe water stop belt, mutual suction force exists between the steel sheet piles, time and labor are saved during installation, and the cofferdam is not easily affected by the water flow or loosened when maintained.

Description

technical field [0001] The invention relates to the field of road and bridge construction, in particular to a steel sheet pile cofferdam water stop and a water stop process. Background technique [0002] Roads and bridges often need to cross the water surface during the construction process. In order to drive piles underwater, it is necessary to artificially create cofferdams and temporarily drain the pool (river, sea) water to facilitate piling. Man-made cofferdams generally use steel plates that can engage with each other to enclose an area, and the problem that must be solved is the water stop problem at the joint of the steel plates. [0003] The traditional way to stop water in cofferdams is to use butter, wood chips and cotton ropes embedded in the locks of adjacent steel plates to block the gaps. However, this process requires professional divers to dive into the bottom of the water for a long time to embed the above-mentioned materials into the lock bit by bit. Ther...
