五十年代后期开始用板桩灌注墙取代钢板桩作为砂砾透水基础的防渗措施。施工方法是,将加厚的钢板桩打至设计深度后,拔出钢板桩;并同时通过焊在钢板桩上的灌浆管向桩底灌注浆液,注满桩体上拔时留下的空间。浆体凝固后即形成连续灌注墙。因此,它是一种将钢板桩与灌浆技术结合起来的一种基础防 In the late 1950s, the use of sheet pile perfusion wall instead of steel sheet pile as the basis of seepage control measures of gravel. The construction method is that after the thickened steel sheet pile is hit to the design depth, the steel sheet pile is pulled out; meanwhile, the grout pipe welded on the steel sheet pile is used to fill the grouting pipe to the bottom so as to fill up the space left when the pile is pulled up. Slurry solidification after the formation of continuous perfusion wall. Therefore, it is a kind of basic prevention which combines steel sheet pile with grouting technology
