Mountain slope deep foundation pit supporting construction method based on single-side formwork
The invention relates to the technical field of slope supporting, in particular to a mountain slope deep foundation pit supporting construction method based on a single-side formwork. The mountain slope deep foundation pit is excavated in a layered mode, the single-side formwork is erected in a layered mode, excavation of the mountain slope deep foundation pit and erection of the single-side formwork are alternately carried out, steel bars are bound on a slope plate base face, the single-side formwork is installed, concrete is poured between the installed and fixed single-side formwork and the slope plate base face, the formworks are removed after the concrete is solidified, and then the mountain slope deep foundation pit is constructed. And earth excavation is continuously conducted on the next layer, and a bearing structure is arranged on the bottom face of the slope plate. According to the construction method for supporting the concrete wall through the single-side formwork, traditional bottom-to-top construction is changed into top-to-bottom construction, meanwhile, an excavated foundation pit face can be effectively supported through the single-side formwork support, and therefore the construction period is shortened, the construction quality is improved, and safety is ensured; due to the fact that the concrete wall structure is supported by the single-side formworks from top to bottom, the foundation pit is prevented from being completely excavated to the base to construct the concrete wall.
本发明涉及边坡支护的技术领域，尤其是涉及一种基于单侧模板的山体边坡深基坑支护施工方法。所述山体边坡深基坑采用分层开挖，所述单侧模板采用分层搭设，其中，山体基坑开挖和单侧模板搭设交替进行，坡板基面上绑扎钢筋并安装单侧模板，在安装固定完的单侧模板与坡板基面之间浇筑混凝土，等待混凝土凝固后拆除模板，继续对下一层进行土方开挖，在坡板底面设置承托结构。该单侧模板支撑混凝土墙体的施工方法是将传统的自下而上施工改为自上而下施工，同时单侧模板支撑也可以有效支撑已开挖基坑面，从而节省了工期，提高了施工质量，确保了安全性，由于自上而下分部进行单侧模板支撑混凝土墙体结构，避免基坑全部开挖至基底施工混凝土墙体。
