Pipeline foundation pit steel sheet pile supporting structure and construction method thereof
The invention relates to a pipeline foundation pit steel sheet pile supporting structure and a construction method thereof, and the main technical scheme is that the pipeline foundation pit steel sheet pile supporting structure comprises a plurality of steel plate pieces and channel steel; the steel plate piece comprises a main plate, the two sides of the main plate in the width direction are obliquely bent in the same direction to form wing plates, the steel plate piece is in an n shape, the opening directions of the adjacent steel plate pieces are opposite, the opening of the channel steel and the opening of the steel plate piece are oppositely arranged, the side edge of the channel steel is connected with the steel plate piece, and the channel steel is connected with the main plate. A soil trapping cavity is defined by the channel steel and the steel plate piece. By arranging the combination of the steel plate piece and the channel steel, on one hand, a tubular-like structure is formed, the bending resistance and the anchoring stability are greatly improved, on the other hand, the soil trapping cavity is formed, a compact soil body in the soil trapping cavity serves as a part of the steel plate pile, namely, the steel plate pile forms a retaining wall-like structure to jointly resist the pressure of a peripheral soil body, and the retaining wall-like structure is formed. Therefore, the loading capacity is greatly improved.
本申请涉及一种管道基坑钢板桩支护结构及其施工方法，其中主要技术方案为一种管道基坑钢板桩支护结构，其包括多根钢板件、槽形钢；所述钢板件包括主板，所述主板的宽度方向的两侧均同向倾斜弯折成型有翼板，所述钢板件呈“︹”字形，相邻钢板件的开口朝向相反设置，所述槽形钢的开口与所述钢板件的开口相对设置，所述槽形钢的侧边与所述钢板件连接，所述槽形钢与所述钢板件合围形成有困土腔。本申请通过设置钢板件和槽形钢的组合，一来，形成类管状结构，抗弯性能和锚固稳定性大大提高，二来，形成有困土腔，以将困土腔内的致密土体作为钢板桩的一部分，即钢板桩形成类挡土墙结构，以共同抵御外围土体的压力，从而大大提高了承压能力。
