Construction method of goaf pile foundation based on BIM
The invention discloses a construction method of a goaf pile foundation based on BIM. The construction method comprises the following steps that a goaf is measured; designing a concrete pouring area of the goaf; splitting a concrete pouring area of the goaf; measuring and setting out; construction of the prefabricated pipe pile is conducted; the guide pipe is connected with the pouring bag, and the pouring bag is placed into the goaf through the prefabricated pipe pile; concrete is gradually poured into the pouring bags through the guide pipes until concrete piers are formed in the goaf; pulling out the catheter; a reinforcement cage is arranged in the prefabricated pipe pile, concrete is poured in the prefabricated pipe pile, and the concrete in the prefabricated pipe pile and the concrete pier in the goaf form an overall stress structure. The construction method has the beneficial effects that the concrete injected into the goaf is limited through the pouring bag, the use amount of the concrete can be controlled, the input of the concrete is reduced, and the construction cost is reduced; successive pouring is carried out in the pouring bag, and therefore the buttress with the small upper portion and the large lower portion can be formed, good supporting of the pile foundation is guaranteed, and the overall stress effect of the pile foundation is guaranteed.
本申请公开了一种基于BIM的采空区桩基的施工方法，包括如下步骤：测量采空区；进行采空区混凝土浇筑区的设计；进行采空区混凝土浇筑区的拆分；测量放线；进行预制管桩的施工；将导管与浇筑袋连接，并将浇筑袋通过预制管桩放入采空区；通过导管向浇筑袋逐次浇筑混凝土，直至在采空区形成混凝土墩；拔出导管；在预制管桩内安置钢筋笼并浇筑混凝土，预制管桩内混凝土与采空区内的混凝土墩形成整体受力结构。本申请的有益效果：利用浇筑袋对采空区注入的混凝土进行限制，可以控制混凝土的用量，减少混凝土的投入，降低施工成本；在浇筑袋内进行逐次浇筑，从而能够形成上小下大的支墩，保证对桩基础的良好支撑，保证桩基础整体的受力效果。
