Abstract
A steel sheet pile cofferdam structure located in a foundation pit comprises steel sheet piles, positioning piles, guide beams and inner supports. Meshing openings of the steel sheet piles are fastened with one another to form seal drums along the inner side of the foundation pit. The horizontal annular guide beams are closely attached to the inner sides of steel sheet piles. The positioning piles are distributed at intervals on the inner sides of the guide beams and fixedly connected with the guide beams. The guide beams are layered along the depth direction of the foundation pit. The inner supports are distributed at intervals between guide beams on the same layer on opposite sides of the foundation pit. Guide beam supports disposed at intervals are rested on the lower sides of the guide beams. Each guide beam support is welded by a horizontal support and an inclined support. Guide beam positioning parts disposed at intervals are pressed on the upper sides of the guide beams. Each guide beam positioning part is welded by a horizontal pressing part and an inclined pulling part. The guide beam supports and the guide beam positioning parts are in up and down one-to-one correspondence and fixedly integrated with the positioning piles. The technical problem that steel sheet pile cofferdam lapping cannot be performed smoothly in traditional deep foundation pits due to insufficient strength of the guide beams is solved. Construction is simple, and construction period is shortened.
