···········································································背水反压堵漏法有注浆法和嵌缝法二种方法配套施士··············································································先凿开隧道与水泥交界处的一周，将水泥凿成3.5*4.5的U型缝口和平面漏水处的每一个漏缝都成U型，清理漏水层表面,冲洗干净后,即使用速凝止水材料进行埋管、抽营、引水减流作业,凹槽不要一次填满,以便为嵌缝留出余地,每隔一定的距离里设一个竹节(注浆嘴),速凝材料达到一定强度后,就可能过竹节反压灌注弹性堵漏浆液,一直灌至变形缝不再出水为止,遇水膨胀速凝,然后在止水的变形缝凹柄上部用浇注料嵌填压实表面层·········································采用材料防水和结构防水相结合,即刚柔相结合的长效防水堵漏工艺··················································································································
