Assembly type foundation pit inner support structure convenient to disassemble and construction method
The invention belongs to the technical field of underground foundation pit engineering, and particularly relates to an assembly type foundation pit inner support structure convenient to disassemble and a construction method. The assembly type foundation pit inner support structure comprises an enclosure structure and assembly type supports, wherein a top beam is arranged on the top of the enclosure structure, a waist beam is arranged on the inner side of the enclosure structure, and the assembly type supports are supported between two opposite sides of the top beam as well as between two opposite sides of the waist beam; and the assembly type supports are formed in a way that a plurality of prefabricated support sections are spliced, and a disassembly gasket is arranged between at least two adjacent prefabricated support sections. According to the assembly type foundation pit inner support structure, the disassembly gasket is arranged between at least two adjacent prefabricated supportsections in the assembly type supports, so that the disassembly gasket can be disassembled first during disassembly, the axial force between the prefabricated support sections is eliminated, the disassembly difficulty of the prefabricated support sections is reduced, and the disassembly efficiency of the assembly type supports is improved.
本发明属于地下基坑工程技术领域，具体涉及一种便于拆卸的装配式基坑内支撑结构及施工方法，包括围护结构和装配式支撑；所述围护结构的顶部设有冠梁，所述围护结构的内侧设有腰梁，所述冠梁相对的两侧之间以及所述腰梁相对的两侧之间均支撑有所述装配式支撑；所述装配式支撑由多个预制支撑节段拼接而成，且至少其中两个相邻的预制支撑节段之间设置有拆卸垫片。本发明通过在装配式支撑中的至少某两个相邻的预制支撑节段之间设置拆卸垫片，以便于在拆卸时可以先拆除拆卸垫片，消除预制支撑节段间的轴力，降低预制支撑节段拆卸的难度，提高装配式支撑的拆卸效率。
