Description

technical field

[0001] The invention relates to a construction method of a composite steel sheet pile cofferdam for a deep-water cap located on a steep-slope hard rock bed. The method is based on the traditional construction method of a steel sheet pile cofferdam and is improved. By improving the layout of the steel sheet pile cofferdam in water Combined with the cofferdam structure, a composite steel sheet pile cofferdam can be applied to the construction of deep water caps on steep hard rock riverbeds, making the construction of caps on steep hard rock riverbeds in water simpler, more efficient, safer and more economical. Background technique

[0002] At present, most domestic bridges in the water adopt the form of high pile caps, and the underwater construction of high pile caps often requires the arrangement of cofferdams. The construction process mainly includes erecting cofferdams, cofferdam pumping, and caps construction. For the construction of caps located in deep w...
