Efficient construction method for curtain grouting in water conservancy project construction
The invention provides an efficient curtain grouting construction method for hydraulic engineering construction, and belongs to the technical field of hydraulic engineering construction. The efficient curtain grouting construction method for hydraulic engineering construction comprises the steps of measuring and determining a grouting hole, drilling the grouting hole, lowering a grouting inner pipe and grouting the grouting hole; according to the method, the upper end face of the impermeable rock stratum is measured through the total station, and when the drilling depth is determined, the lowest end of the drilling hole is 1.5 m below the upper end face of the impermeable rock stratum at the position corresponding to the grouting hole, so that it can be guaranteed that the depth of the lower end of the grouting hole penetrating into the impermeable rock stratum reaches the standard; investment increase and cement resource waste caused by too deep grouting holes are avoided; limiting blocks are arranged between the grouting inner pipe and the grouting holes, the grouting inner pipe is relatively fixed, shaking of the grouting inner pipe in the grouting process is reduced, and when cement is filled into the upper end of the anti-seepage material, the filling inner pipe is lifted at a constant speed according to the filling speed, so that the filling holes are evenly filled with the cement.
本发明提供一种水利工程施工帷幕灌浆高效施工方法，属于水利工程施工技术领域，该水利工程施工帷幕灌浆高效施工方法包括测量确定灌浆孔、钻取灌浆孔、下灌浆内管和往灌浆孔内灌浆；本发明中，通过全站仪进行不透水岩层上端面的测量，确定钻孔深度时，钻孔最低端位于对应灌浆孔位置的不透水岩层上端面以下1.5m，即能保证灌浆孔的下端深入不透水岩层的深度达到标准，又避免灌浆孔过深而造成投资增加和水泥资源的浪费；在灌浆内管和灌浆孔之间设置限位块，进行灌浆内管的相对固定，减少灌浆过程中灌浆内管的晃动，往防渗料上端灌装水泥时，根据灌装速度进行灌装内管的匀速上提，使水泥均匀的充满灌装孔。
