Assembly type hollow concrete-filled steel pipe supporting system and construction method thereof
The invention belongs to the technical field of underground foundation pit engineering, and particularly relates to an assembly type hollow concrete-filled steel pipe supporting system and a construction method thereof. The supporting system comprises an enclosure structure and an assembly type hollow concrete-filled steel pipe support. A top beam is arranged at the top of the enclosure structure,a waist beam is arranged at the inner side of the enclosure structure, and an assembly type hollow concrete-filled steel pipe support is supported between the two opposite sides of the waist beam andbetween the two opposite sides of the top beam correspondingly. The assembly type hollow concrete-filled steel pipe support is formed by splicing a plurality of hollow concrete-filled steel pipe support prefabricated parts, and the hollow parts of the hollow concrete-filled steel pipe support prefabricated parts are communicated. Latticed columns and steel enclosing purlins are further arranged inside the enclosure structure, the multiple steel enclosing purlins are arranged on the latticed columns in the height direction of the latticed columns, and the steel enclosing purlins are connectedwith the assembly type hollow concrete-filled steel pipe supports. According to the assembly type hollow concrete-filled steel pipe support, the hollow parts of the multiple hollow concrete-filled steel pipe support prefabricated parts are communicated, so that the assembly type hollow concrete-filled steel pipe support is higher in bearing capacity and stronger in deformation resistance, and foundation pit engineering safety is guaranteed.
本发明属于地下基坑工程技术领域，具体涉及一种装配式空心钢管混凝土支撑系统及其施工方法，包括围护结构和装配式空心钢管混凝土支撑；围护结构的顶部设有冠梁，内侧设有腰梁，腰梁相对的两侧之间及冠梁相对的两侧之间均支撑有装配式空心钢管混凝土支撑；装配式空心钢管混凝土支撑由多个空心钢管混凝土支撑预制件拼接而成，且多个空心钢管混凝土支撑预制件的中空部连通；围护结构内还设有格构柱和钢围檩，格构柱上沿其高度方向设有多个钢围檩，钢围檩与装配式空心钢管混凝土支撑连接。本发明的装配式空心钢管混凝土支撑的多个空心钢管混凝土支撑预制件的中空部连通，使得装配式空心钢管混凝土支撑的承载能力更高、抗变形能力更强，确保基坑工程安全。
