Problems solved by technology
This method is less efficient. In the process of sealing the back, if the cofferdam area is large, it is necessary to move the pouring device multiple times, and the pouring device is large in size, which requires a lot of manpower and material resources; Sand is used to improve the impact resistance of the cofferdam. Although this method can effectively improve the impact resistance of the cofferdam, the fine sand filled in is not easy to recover after construction

The invention relates to a steel sheet pile cofferdam which comprises a steel sheet pile cofferdam guide frame, a steel sheet pile cofferdam temporary casting platform and a steel sheet pile cofferdamstabilizing system. The steel sheet pile cofferdam stabilizing system comprises a steel casing, a transverse support, a longitudinal support, a balance sand pocket, a hoisting machine and a lifting platform; the steel sheet pile cofferdam guide frame comprises an inner guide frame, an outer guide frame and a guide frame support system; the steel sheet pile cofferdam temporary casting platform comprises a fixed sliding rail, a casting platform and a casting device. The steel sheet pile cofferdam has the advantages that the fixed sliding rail is fixed to the top of the steel casing, the castingplatform is embedded into the fixed sliding rail, platform sliding wheels are arranged on the platform, so that the casting platform can slide along the fixed sliding rail, in addition, the casting device can slide along a casting pipe slide on the casting platform, and finally, a back cover can cover a whole cofferdam site.
Description
technical field [0001] The invention belongs to the field of cofferdams, in particular to a steel sheet pile cofferdam and a construction method thereof. Background technique [0002] Cofferdam refers to the temporary enclosure structure built for the construction of permanent water conservancy facilities in the construction of water conservancy projects. Its function is to prevent water and soil from entering the construction site of the building, so as to drain water in the cofferdam, excavate the foundation pit, and build the building. Generally, it is mainly used in hydraulic construction. Except as a part of formal buildings, cofferdams are generally removed after use. The height of the cofferdam is higher than the highest water level that may occur during the construction period. Traditional cofferdams tend to be crooked during the process of driving steel sheet piles, so it is necessary to excavate a pit suitable for the size of the steel sheet piles in advance, and...
