泥浆冲击槽孔施工,是在土石坝体内和松散透水地基中建造混凝土防渗墙槽孔的一种方法,其主要特点是采用不循环泥浆固壁,钢丝绳冲击钻孔冲打槽形孔.1978~1979年,在南城子水库副坝的泥浆冲击槽孔施工中,为了解决由于财力、物力缺乏和钻具加工能力不足的困难,我们采取了土洋结合的办法,对目前国内习用的施工机具和方法作了一些适应中小型水利工程施工力量的改进,主要包括:不同机型组合进行造孔作
Mud impact slot construction is a method of constructing a concrete impervious wall slot in an earth-rock dam body and a loosely permeable foundation. Its main feature is the use of non-circulating mud solid wall and steel wire rope impact drilling to puncture slot holes. ~ In 1979, in the construction of the slurry impact slot of the Nanbazi sub-dam, in order to solve the difficulties caused by the lack of financial resources, material and physical resources, and lack of drilling capacity, we adopted a combination of earth and ocean to improve the current domestic construction machinery And methods made some adapt to the construction of small and medium-sized hydraulic engineering improvements, including: different combinations of holes for making
