The invention relates to a steel sheet pile insertion auxiliary positioning device and a steel sheet pile cofferdam construction process thereof, the steel sheet pile insertion auxiliary positioning device comprises a guide beam, a limiting assembly and at least two clamping assemblies, and the guide beam comprises two guide rails which are concentrically arranged and is used for vertically extending a steel sheet pile into the space between the two guide rails; the two clamping assemblies are arranged on the two guide rails correspondingly, each clamping assembly comprises a sliding strip, a clamping block and an abutting piece, the sliding strips are detachably connected to the guide rails in a sliding mode, the clamping blocks are hinged to the sliding strips, and hinge shafts of the clamping blocks are parallel to the guide rails and used for stretching into the pile grooves; the abutting piece is arranged on the clamping block and can enable the clamping block to be close to or away from the other guide rail. The limiting assembly is detachably connected to the guide rail and used for abutting against the unconnected side of the steel sheet pile. The steel sheet pile inserting perpendicularity can be guaranteed, and the construction quality of the steel sheet pile cofferdam is improved.
Description
technical field [0001] The application relates to the field of foundation pit maintenance and construction, in particular to a steel sheet pile insertion auxiliary positioning device and a steel sheet pile cofferdam construction process. 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. The most primitive cofferdam is to use silt and gravel to build watertight dams at bridge piers or abutments; with the progress of the times, my country's cofferdam technology has become more and more mature. Steel sheet pile cofferdam, as a surrounding water structure for deep-water bridge foundation construction, is a type of steel with locks. It is not o...
