Foundation pit groove steel sheet pile profile steel supporting system and construction method
The invention discloses a foundation pit groove steel sheet pile profile steel supporting system and a construction method. The supporting system comprises enclosure structures laid along the inner side wall of a foundation pit groove, an upper supporting structure arranged at the two ends of the opening of the foundation pit groove in a crossing mode and fixed to the side walls of the upper ends of the enclosure structures, and a plurality of lower supporting structures arranged below the opening and above the bottom of the foundation pit groove, and the two ends of the lower supporting structure are connected with the enclosure structures arranged on the two sides in the foundation pit groove; and the lower supporting structure comprises lower steel enclosing purlins and lower profile steel supporting beams, the multiple layers of lower steel enclosing purlins are arranged on the enclosure structures, the lower steel enclosing purlins are connected to the surfaces of the enclosure structures through bolts in the surrounding direction of the inner side wall of the foundation pit groove, and the multiple lower profile steel supporting beams which are parallel to one another are arranged in the width direction of the foundation pit groove. By means of the construction method, prestress can be effectively applied to the supporting system when the excavation depth of the foundation pit groove is large, deformation of the foundation pit groove can be better prevented, and it is guaranteed that the whole supporting system is evenly stressed.
本发明公开了一种基坑槽钢板桩型钢支撑系统及施工方法，所述支撑系统包括沿基坑槽内侧壁铺设的围护结构、横跨设置在基坑槽口部两端且固定在围护结构上端侧壁上的上支撑结构和设置在基坑槽的口部以下与底部之上的多道下支撑结构，该下支撑结构的两端与设置在基坑槽内两侧的围护结构连接；下支撑结构包括下钢围檩和下型钢支撑梁，在围护结构上分别设置多层所述下钢围檩，且下钢围檩沿基坑槽的内侧壁环绕方向通过螺栓连接在围护结构表面上，沿基坑槽的宽度方向上设置多根相互平行的所述下型钢支撑梁。本发明的施工方法能有效解决了当基坑槽开挖深度较深时可以对支护体系施加预应力，能够更好的防止基坑槽变形，保证支护体系整体受力均匀。
