Mudstone natural foundation fissure water drainage construction method
The invention provides a mudstone natural foundation fissure water drainage construction method. The mudstone natural foundation fissure water drainage construction method comprises the steps of foundation pit excavation, water storage pit construction, fissure water flow guiding, steel sleeve pre-burying, bedding, waterproof construction, check ball valve mounting, structure construction and thelike. By means of the impermeable characteristic of a mudstone foundation, fissure water can be effectively collected and drained in the basic construction stage. Scattered fissure water is intensively gathered into a water storage pit through a flow guiding groove, then the water storage pit is isolated from a structural layer through a galvanized steel pipe, water source permeation is prevented,a complete fissure water drainage system is formed through a vacuum pump and a check ball valve, and the problems that in the current construction process, when an impermeable mudstone natural foundation is encountered, seepage water cannot be drained in time, and the later-period structure safety is poor are solved.
本发明提供了泥岩天然地基裂隙水疏排施工方法，包括：基坑开挖、储水坑施工、裂隙水引流、钢套管预埋、垫层、防水施工、止回球阀安装和结构施工等步骤，利用泥岩地基不透水特点，在基础施工阶段可有效的将裂隙水收集并疏排，通过引流槽将零散裂隙水集中汇入储水坑中，再利用镀锌钢管将储水坑与结构层隔离，防止水源渗透，利用真空泵与止回球阀形成一套完善的裂隙水疏排系统，解决了目前施工过程中遇到不透水的泥岩天然地基时出现渗水无法及时排走以及的后期结构安全问题。
