Three-dimensional grouting plugging method for continuous gushing water of sea-filled stratum
The invention discloses a three-dimensional grouting plugging method for continuous gushing water of a sea-filled stratum. The method includes the steps that S1, a drainage pipe and a backfill grouting pipe are inserted into a water gushing point of a water gushing section of a foundation pit; S2, a tunnel face of the water gushing point is plugged; S3, grouting holes are formed in a ground surface; S4, leaking stoppage grouting is conducted on the water gushing section of the foundation pit through the grouting holes, and meanwhile concrete pouring is conducted on the tunnel face of the water gushing point; S5, holes and pores around the consolidated cement in the water gushing section are backfilled through the backfill grouting pipe, and compaction grouting is conducted; and S6, after backfill grouting is conducted for 12 h, whether the water gushing section is densely filled or not is detected through an advanced geological radar, and if holes or cavities exist, the holes are drilled in the corresponding positions for filling grouting. According to the three-dimensional grouting plugging method for the continuous gushing water of the sea-filled stratum, three-dimensional grouting combining the tunnel face and a earth surface is adopted, plugging and leaking stoppage can be rapidly, accurately and effectively conducted on the water gushing point, effective treatment is conducted on the water gushing point in a short time, foundation pit construction safety is guaranteed, and the method has a high popularization prospect.
本发明公开了一种填海地层连涌涌水立体式注浆封堵方法，其步骤如下：S1：在基坑涌水段的涌水点插入引排管与回填注浆管；S2：对涌水点的掌子面进行封堵；S3：在地表打设注浆孔；S4：通过注浆孔对基坑涌水段进行堵漏注浆，同时对涌水点的掌子面进行混凝土浇筑；S5：通过回填注浆管对涌水段内的固结的水泥周围空洞以及孔隙进行回填、压实注浆；S6：回填注浆12h后，通过超前地质雷达探测涌水段是否填充密实，若存在孔隙或空洞，则在对应位置处钻孔进行填充注浆；本方法中采用掌子面+地表相结合的立体式注浆，能够快速、精准、有效地对涌水点进行封堵、堵漏，在短时间内对涌水点进行有效治理，确保基坑施工安全，具有较高的推广前景。
