Assembling type foundation pit support structure and construction method
The invention discloses a split mounting type foundation pit support structure and a construction method, and relates to the field of foundation pit design and construction, the split mounting type foundation pit support structure comprises a prefabricated diaphragm wall, the top of the prefabricated diaphragm wall is connected with a first prefabricated support through a cast-in-place top beam, and the inner side of the prefabricated diaphragm wall is connected with a second prefabricated support through a prefabricated waist beam; each prefabricated underground diaphragm wall comprises at least two underground diaphragm wall sections with different heights, and the adjacent prefabricated underground diaphragm walls are spliced in a staggered joint mode. The underground diaphragm wall sections are spliced in a concave-convex tenon mode, and a plurality of thin-wall cavities are formed in the underground diaphragm wall sections. The high-performance steel fiber reinforced concrete is adopted to replace traditional reinforced concrete, the underground diaphragm wall and an inner supporting system are divided into a plurality of prefabricated modules capable of being assembled, the supporting system can be recycled, and the characteristics of high crack resistance, high environmental protection and low self weight of the prefabricated assembly component are achieved; and the building envelope prefabricated assembly modules are quickly connected, so that the construction efficiency is improved.
本发明公开了一种拼装式基坑围护结构及施工方法，涉及基坑设计及施工领域，包括预制地连墙，所述预制地连墙顶部通过现浇冠梁连接首道预制支撑，预制地连墙内侧通过预制腰梁连接第二道预制支撑；所述预制地连墙包括至少两节高度不同的地连墙节，相邻预制地连墙采用错缝拼接；地连墙节之间采用凹凸榫式拼接方式，且所述地连墙节内设有若干薄壁空腔。本发明采用高性能钢纤维混凝土代替传统钢筋混凝土，将地下连续墙及内支撑体系分为多个可拼装预制模块，其中的支撑体系可重复循环利用，实现预制拼装构件高抗裂、高环保、低自重的特点；围护结构预制拼装模块之间采用快速连接方式，提高施工效率。
