Construction method for pile foundation in karst area
The invention discloses a karst area pile foundation construction method. The karst area pile foundation construction method comprises the following steps that S1, address hydrological conditions of a pile foundation area are obtained and evaluated; s2, a pile foundation construction scheme is designed according to the evaluation result; s3, a pile foundation construction scheme is designed, and BIM simulation is conducted according to the scheme and address hydrological conditions of a pile foundation area; s4, foundation pit excavation is conducted according to the simulation result; s5, an outer pile casing is buried to the preset pile bottom position in the karst ground, and rock soil in the outer pile casing is dug out, so that a pile hole matched with the outer wall of the outer pile casing is formed in the karst ground; s6, an inner pile casing is installed in the outer pile casing, a reinforcement cage is installed in the inner pile casing, concrete is poured into the inner pile casing, and after the concrete is condensed, the concrete and the reinforcement cage form a pile body; s7, the outer pile casing is pulled out, a filling gap is formed between the inner pile casing and the hole wall of the pile hole, and the filling gap is filled with gravel; the pile forming quality of pile foundation construction is high, and the structural stability is good.
本发明公开了一种岩溶地区桩基施工方法，包括以下步骤：S1、获取桩基地区的地址水文条件并进行评价；S2、依据评价结果设计桩基施工方案；S3、设计桩基施工方案并将依据该方案以及桩基地区的地址水文条件进行BIM模拟；S4、根据模拟结果进行基坑开挖；S5、埋设外护筒至岩溶地面内的预设桩底位置，并挖出所述外护筒内的岩土，以使岩溶地面内形成与所述外护筒的外壁匹配的桩孔；S6、在所述外护筒内安装内护筒，在所述内护筒内安装钢筋笼，向所述内护筒内浇注混凝土，混凝土凝结后与所述钢筋笼形成桩身；S7、将所述外护筒拔出，所述内护筒与桩孔的孔壁之间形成填充间隙，向所述填充间隙内填充碎石；本发明桩基施工的成桩质量高且结构稳定性好。
