Steel sheet pile cofferdam connecting structure for hydraulic engineering construction

Abstract

The invention relates to a steel sheet pile cofferdam connecting structure for hydraulic engineering construction. The steel sheet pile cofferdam connecting structure comprises two sets of first threaded rods, and channel steel is integrally formed on the vertical edges of the two sides of a steel sheet pile; first connecting blocks are fixed to the vertical end faces of the sides, deviating from notches, of the groove bottoms of all the sets of steel sheet piles, horizontally-formed first through holes are formed in all the sets of first connecting blocks in a penetrating mode, the axes of the first through holes are parallel to the plane where the groove bottoms of the steel sheet piles are located, and all the sets of first threaded rods are jointly inserted into all the sets of first through holes; the first threaded rods are in threaded connection with a plurality of sets of first nuts, every two sets of first nuts are distributed in one set, and the two sets of first nuts abut against and are fixed to the vertical end faces of the two sides of each set of the first connecting blocks; and wing plates of the two sets of channel steel close to each other of any two adjacent sets of steel sheet piles are kept attached. According to the steel sheet pile cofferdam connecting structure for hydraulic engineering construction, gaps between the steel sheet piles are reduced, so that the overall compactness of a cofferdam is improved, and the probability of water leakage caused by the gaps between the steel sheet piles is reduced.

Description

technical field [0001] The present application relates to the field of cofferdam installation, in particular to a steel sheet pile cofferdam connection structure for hydraulic engineering construction. 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. The function of the cofferdam 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. During the construction of the water conservancy project, the cofferdam is installed at the location to be constructed, and the cofferdam is dismantled after the construction is completed. [0003] In bridge foundation construction, when bridge piers and abutment foundations are below the surface water level, various forms of earth weirs can be built according to local materi...

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that there are the following defects: during the construction of water conservancy projects, construction personnel need to use engineering ships to insert and drive each group of steel sheet piles at the designated water area, and the head and tail of each group of steel sheet piles connection; among them, for steel sheet piles with a groove-shaped cross section, the two sides of each group of steel sheet piles are hooked and fixed; since the position accuracy of each group of steel sheet piles in the process of insertion and driving is difficult to accurately control, the adjacent two groups of steel sheet It is inevitable that there will be a gap when the edge of the cofferdam is articulated, and the position of the gap will easily cause water leakage in the formed cofferdam, which will cause great inconvenience to the internal construction of the cofferdam in the later stage, so there is room for improvement
