Reverse-construction-method basement construction method
The invention provides a reverse-construction-method basement construction method. The reverse-construction-method basement construction method comprises the following steps that a vertical supporting system is constructed, an underground diaphragm wall is constructed, joint bars are reserved at the elevation positions, corresponding to structural beam plates of all layers, of the underground diaphragm wall, connectors are reserved at the positions, corresponding to bottom plates, of the underground diaphragm wall, joints and internal corners of the underground diaphragm wall are reinforced and waterproof, and vertical supporting columns are constructed; a first layer is excavated, a ring beam and a structural beam plate of a top layer are constructed, and the joint bars are bent and anchored into the structural beam plate of the top layer; a secondary layer is excavated, a structural beam plate of the secondary layer is constructed, and the joint bars are bent and anchored into the structural beam plate of the secondary layer; a vertical structure is constructed between the structural beam plate of the top layer and the structural beam plate of the secondary layer; secondary backbuilding of the vertical structure is conducted; the construction of each layer of structural beam plate is repeated until the construction of the bottom plate is completed; a mold is maintained and removed, and a structural beam plate hole is repaired; and a drainage system is constructed. Outer wall waterproof painting is not needed, and the construction procedure is simplified; and the stress of a vertical component at the joint is effectively and reliably transmitted through secondary backbuilding, and the bearing performance is guaranteed.
本发明提供了一种逆作法地下室施工方法，包括如下步骤：竖向支撑体系施工，构建地下连续墙，地下连续墙对应各层结构梁板标高处预留插筋、对应底板处预留接驳器，地下连续墙的接缝及阴角处加固并防水，构建竖向支撑柱；首层开挖，施工圈梁及顶层的结构梁板，将插筋弯锚至顶层结构梁板中；次层开挖，施工次层的结构梁板，将插筋弯锚至次层结构梁板中；在顶层的结构梁板与次层的结构梁板之间施工竖向结构；竖向结构二次回筑；重复各层结构梁板施工直至完成底板施工；养护拆模，修复结构梁板孔洞；构建排水引流体系。本方法无需进行外墙防水粉刷，简化施工工序；通过二次回筑使竖向构件在接缝处应力有效、可靠地传递，保证承载性能。
