Construction method of underground frame structure
The invention relates to a construction method of an underground frame structure. The construction method comprises the steps of construction preparation; constructing an enclosure supporting system; digging a basin-type area; constructing a pile foundation bearing platform; constructing a water collecting well; constructing a foundation slab and a supporting upright post; bottom plate inverted haunch angle construction; constructing a side wall single-side template system; constructing a deformation-adjustable concrete horizontal support; excavating a back pressure area; constructing a second steel support; constructing a slope bottom plate; and constructing a post-cast strip independent formwork system. By adopting the deformation-adjustable concrete horizontal support, the bottom plate chamfering template mounting and stabilizing system and the post-cast strip independent formwork supporting system, the method is suitable for large-scale building engineering construction with large depth and large area, the construction efficiency is improved, the construction period is shortened, meanwhile, the stability of the side slope and the back pressure of reserved soil can be effectively controlled, and the construction period is shortened. And the safety and stability in the foundation pit construction process are guaranteed, and wide application prospects are achieved.
本发明涉及一种地下框架结构的施工方法，包括步骤：施工准备；围护支撑系统施工；盆式区域开挖；桩基承台施工；集水井施工；基础底板及支撑立柱施工；底板倒腋角施工；侧墙单侧模板体系施工；变形可调混凝土水平支撑施工；反压区域开挖；第二道钢支撑施工；斜坡底板施工；后浇带独立支模体系施工。本发明采用变形可调混凝土水平支撑、底板倒角模板安装稳固体系和后浇带独立支模体系，适用于深度较深和面积大的大型建筑工程施工，提高了施工效率，缩短了工期，同时可以有效地控制边坡的稳定性和留土反压力，保证基坑施工过程中的安全性和稳定性，具有广阔的应用前景。
