Abstract

The invention discloses a steel pipe pile locking notch structure and a water-stopping method of a steel pipe pile cofferdam by using the structure. The notch-locking structure comprises steel pipe piles and locking notches, wherein the steel pipe piles are arranged at intervals, each locking notch is arranged between two adjacent steel pipe piles, each locking notch comprises a female locking notch and a male locking notch, the male locking notch is I-shaped steel, the female locking notch is a steel pipe which is provided with a slit along the axial direction, and an I-shaped steel web plate is inserted into the slit. When the locking notch structure is used for leak stoppage, clay is pounded into the cavities of the locking notches, and reinforcing steel bars are inserted to carry out compaction processing for the clay. The invention relates to an effective locking notch structure and the water-stopping method thereof which are disclosed specially for solving the problem of difficult water prevention and leak stoppage of the locking notches in the steel pipe pile cofferdam.

Description

technical field [0001] The invention relates to a lock structure of a steel pipe pile cofferdam and a water-stopping method for a steel pipe pile cofferdam. Background technique [0002] At present, for the construction of bridge caps with low water level, steel pipe pile cofferdams are mostly used. The steel pipe pile cofferdam is suitable for various complex geology and strata, and has the advantages of fast construction speed, simple process, less equipment required, high section rigidity, and less internal support. However, due to the large number of locks, most of the waterproof and plugging problems are very difficult, so the research on improving the waterproof and plugging ability of the locks is extremely important. Contents of the invention [0003] The object of the present invention is to provide a very effective lock combination structure and a water-stopping method for the steel pipe pile cofferdam, which are specially proposed to solve the difficult problem...
