劈裂式帷幕灌浆法。劈裂式帷幕灌浆主要用于加固堤身,防止堤身渗漏。其方法是根据堤坝曲直不同情况,用孔轻便钻机或更简单的钻具,分别采用梅花形布孔和直线布孔方式,沿堤坝轴线从堤顶离堤外肩1.5m 处钻孔,一般孔距3m,孔深根据堤身情况分别以钻透堤身堤土或穿过堤身钻入基础1～2m为宜。灌浆时由下而上,少灌多复;泥浆由稀到稠,循序渐进;压力由大到小,灵活 Split curtain grouting method. Split curtain grouting is mainly used to reinforce the dike, to prevent leaking levees. The method is based on the different conditions of levees and straights, drilling with holes or more simple drilling tools, respectively, with plum-shaped holes and straight hole cloth way, along the embankment dike from the embankment dike shoulder 1.5m outside the hole, the general hole pitch 3m, hole depth according to the situation of the embankment respectively to dig through the dike dike or through the dike into the foundation 1 ~ 2m appropriate. Grouting bottom-up, less irrigation and more complex; mud from thin to thick, step by step; pressure from small to large, flexible
