摘　　要：某输水渡槽伸缩缝漏水问题,采用水溶性聚氨酯化学灌浆材料对渗漏处进行灌浆封堵,然后用聚脲弹性体对整个处理基面进行封闭处理,结果表明:采用3∶7灰土对连接段底部空洞区域进行回填并对灰土内部灌注泥浆处理,施工操作简单、止水效果好。For the water leakage problem of expansion joint of a water conveyance aqueduct,the water soluble polyurethane chemical grouting material is used to grout and seal the leakage,and then the polyurea elastomer is used to seal the entire treatment base surface.The treatment result shows:3:7 lime soil is used to backfill the cavity area at the bottom of the connection section,and the mud is poured to treat the internal part of the lime soil.The construction operation is simple and the water sealing effect is good.
