Foundation pit reinforced concrete inner supporting system and construction method for rapid installation of foundation pit reinforced concrete inner supporting system
The invention discloses a foundation pit reinforced concrete inner supporting system and a construction method for rapid installation of the foundation pit reinforced concrete inner supporting system. The foundation pit reinforced concrete inner supporting system comprises middle horizontal supports and steel stand columns arranged on stand column piles; inner support hoisting devices are arranged at the upper ends of the steel stand columns and the corresponding openings in the inner sides of support walls; all the inner support hoisting devices are connected with the middle horizontal supports through steel slings and hoist the middle horizontal supports in the vertical direction; the inner sides of the support walls and the steel stand columns are detachably connected with the corresponding middle horizontal supports through steel corbels. During construction, the steel stand columns are arranged firstly; secondly, earthwork is excavated for the first time according to the sum of the longitudinal heights of all the middle horizontal supports; the middle horizontal supports and the support hoisting devices are arranged; and finally, the earthwork is excavated one by one according to the required depth of the middle horizontal supports, and the middle horizontal supports are hoisted in place by using the support hoisting devices. By means of the foundation pit reinforced concrete inner supporting system and the construction method, concrete pouring and curing of all reinforced concrete supports can be completed when a shallow foundation pit is excavated.
本发明公开了基坑钢筋混凝土内支撑系统及其快速安装的施工方法，包括中间水平支撑，以及设置于立柱桩的钢立柱；钢立柱的上端，以及支护墙内侧对应开口处均设有内支撑吊装装置；所有内支撑吊装装置均通过钢吊索与中间水平支撑连接，并沿竖直方向吊装中间水平支撑；支护墙内侧，以及钢立柱通过钢牛腿与相应的中间水平支撑之间通过钢牛腿形成可拆卸连接。施工时，先设置钢立柱；然后，根据所有中间水平支撑的纵向高度总和第一次开挖土方；再设置中间水平支撑和支撑吊装装置；最后根据中间水平支撑所需深度逐一开挖土方，并用支撑吊装装置将中间水平支撑吊装就位。本发明能够实现在浅层基坑开挖时就能够完成所有各道钢筋砼支撑的混凝土浇筑与养护。
