污水处理厂截降水工程在近海抛填块石地基中进行,原采用的粘土截水槽与强排水方案,通过在消化池基坑的实施,因受一天两潮的双向水头作用的影响,难以满足施工要求。经多方论证,最终采用了高喷灌浆构筑截水墙配合降水方案,降水效果良好,达到了预期目的,保证了基坑的顺利开挖。 Sewage treatment plant shut-down water projects in the offshore thrown stone base, the original use of clay intercepting tank and strong drainage program, through the implementation of digesters in the pit, due to two days of two-way head effect, it is difficult to meet Construction requirements. The multi-argument, and ultimately the use of high-pressure grouting grouting cuttings constructed with precipitation program, the precipitation effect is good, has reached the desired goal, to ensure the smooth excavation of the foundation pit.
