Combined cofferdam structure and building construction method thereof
The invention discloses a combined cofferdam structure and a building construction method thereof. The combined cofferdam structure is composed of earth rock cofferdams in shallow water areas on the two sides of a riverway and a steel plate pile cofferdam in a deep water area in the center of the riverway. The steel plate pile cofferdam is located between the earth rock cofferdams on the two sides, and composed of a plurality of sets of main cofferdam grids and auxiliary cofferdam grids filled with gravel in a spaced and continuous mode. A foundation covering layer which is formed by manually throwing and filling the gravel and used for locating a steel plate pile is arranged on a riverbed at the bottom of the steel plate pile cofferdam. The construction method comprises the steps that the locating foundation covering layer is formed by throwing and filling the gravel, the steel plate pile is inserted and driven, the cofferdams are closed, the cofferdam grids are filled with the gravel in a throwing mode, and consolidation grouting or high-pressure whirl-spray grouting seepage-proofing construction is carried out. The steel plate pile is embedded in the combination portions of the earth rock cofferdams and the steel pipe pile cofferdam to be fixedly connected with the structure, the two structural bodies are fused well, and the overall cofferdam structure is more stable. The locating foundation covering layer is formed, mounting groove underwater construction is not needed in the method, and efficient and high-quality cofferdam construction is achieved.
