青岛市团岛污水处理厂座落在近海抛填块石地基上,受一天两潮的双向水头作用影响较大,截降水工程原采用粘土截水槽与强排水方案,通过在消化池基坑的实施,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。 Qingdao Tuandao Sewage Treatment Plant is located on the block-filling foundation in the offshore area and is greatly affected by the two-way water heads in one day. The cut-off project originally used a clay cut-off tank and a strong drainage scheme to pass through the pit in the digester. Implementation, it is difficult to meet the construction requirements. After multi-argumentation, high-jet grouting was finally adopted to construct a water interception wall and a precipitation program. The precipitation effect was good, and the expected purpose was achieved, ensuring the smooth excavation of the foundation pit.
