Construction method for pit well of strong weathered rock foundation rich in low-pressure-bearing fissure water
The invention relates to a construction method for a pit well of a strong weathered rock foundation rich in low-pressure-bearing fissure water. The construction method comprises the following steps that (1) a water collecting pit is chiseled in the bottom of the pit well; a flow guide hole is drilled in the side wall of the pit well; a flow guide pipe is plugged into the flow guide hole; a circle of collecting pipes are horizontally arranged on the peripheral side wall of the pit well and are in communication with the flow guide pipes; a drainage pipe is connected to the lowest part of the collecting pipe and extends to the water collecting pit; a water pump is arranged at the bottom of the water collecting pit; pit bottom concrete is poured; a side template supporting cushion block is anchored on the side wall of the pit well; and side formworks corresponding to the side walls of the pit well are installed on the inner sides of the side formwork supporting cushion blocks, scaffold pipes are arranged on the inner sides of the side formworks to outwards support the side formworks, concrete is poured between the side formworks and a rock stratum, the collecting pipe, the drainage pipe and a water pump drainage pipe are poured into the concrete, and the surface of the concrete is cleaned after vibrating and compacting. The constructed pit well is high in strength and good in flatness; and waterproof construction is facilitated, after the water content of the concrete meets the requirement, the bottom plate can be constructed for waterproofing.
本发明涉及一种富含低承压裂隙水的强风化岩地基坑井施工方法，按照以下步骤进行：1)在坑井底部凿出一个收水坑；在坑井侧壁上打导流洞；在导流洞中塞入导流管；坑井四周侧壁水平布置一圈汇流管，汇流管连通各导流管；汇流管最低处连接一根排水管，排水管延伸至收水坑；收水坑底部放置水泵用于排水；浇筑坑底混凝土；在坑井侧壁锚固侧模板支撑垫块；在侧模板支撑垫块内侧安装对应于坑井各侧壁的侧模板，侧模板内侧设脚手管向外支撑侧模板，侧模板与岩层之间浇筑混凝土，将汇流管，排水管及水泵排水管浇筑于混凝土中，振捣密实后混凝土表面清理，本发明施工后的坑井强度高、平整度好。利于防水施工,混凝土含水率满足要求后即可施工底板防水。
