Waterproof construction process for deep hole grouting filling treatment
The invention discloses a waterproof construction process for deep hole grouting filling treatment, and relates to underground water control engineering in a foundation treatment process, which comprises the following steps of: (1) testing the elevation of a diving static water level in a superficial strong permeable layer, or testing the elevation of a water level of confined water rich in a hole or a fracture zone in a deep aquitard; (2) determining the top surface elevation of the aquitard at the to-be-grouted point; (3) determining the permeability coefficient of the cylinder to be applied and replaced; (4) calculating and determining the minimum radius of the replacement cylinder according to the pore-forming radius when the grouting pipe is installed in the grouting construction; (5) a replacement area with poor permeability is constructed at the to-be-gradually-arranged point position; (6) implanting the replacement cylinder into the replacement area; and (7) drilling the center of the replacement cylinder to the depth of the hole or the fracture zone, installing a grouting pipe in the replacement cylinder after drilling, and filling the grouting pipe with grouting. According to the method, the problems caused by a conventional grouting construction process can be solved, the construction cost can be reduced, and the grouting construction quality is guaranteed.
本发明公开了一种深层孔洞注浆填充处理的隔水施工工艺，涉及地基处理过程中地下水控制工程，包括如下步骤：（1）测试浅部强透水层中潜水静止水位标高，或测试深部弱透水层中孔洞或破碎带中富含的承压水水位标高；（2）确定拟注浆点位弱透水层顶面标高；（3）确定拟用于施作置换圆柱体的渗透系数；（4）根据注浆施工安装注浆管时的成孔半径，计算确定置换圆柱体的最小半径；（5）在拟逐渐点位施作渗透性差的置换区；（6）将置换圆柱体植入置换区内；（7）在置换圆柱体中心钻孔至孔洞或破碎带深度，并钻孔后的置换圆柱体内安装注浆管，注浆管填充注浆。本发明不仅可解决常规注浆施工工艺带来的问题，还可以降低施工成本，保证注浆施工质量。
