Complex stratum comprehensive grouting method
The invention discloses a complex stratum comprehensive grouting method. The complex stratum comprehensive grouting method comprises the following steps of arrangement of grouting holes, drilling, hole cleaning, grouting and grout closing, specifically, the arrangement of the grouting holes is conducted in a three-row two-sequence construction mode, the three rows specifically comprise the upstream row and the downstream row which are arranged in an anti-seepage wall and the downstream row outside the anti-seepage wall; drilling grouting holes, specifically, sectional type drilling is performed by adopting weighted slurry wall protection drilling in combination with a hole opening sealing process; grouting of the grouting holes, specifically, segmented grouting is conducted in the mode that sleeve valve pipe grouting is combined with drilling and grouting alternate grouting, and the sleeve valve pipe grouting is conducted through a segmented clamping and plugging method from bottom totop; and the drilling and grouting alternate grouting adopts a top-down sectional type clamping and plugging method for grouting. The grouting method is suitable for high-water-point, water gushing and sand gushing environment grouting, the grouting efficiency is high, the adaptability to variable geology is high, the water blocking curtain is formed completely and stably after the grouting, and potential safety hazards caused by water leakage and water seepage can be greatly reduced or even eliminated.
本申请公开了一种复杂地层综合灌浆方法，包括灌浆孔的排布、钻孔、清孔、灌浆和闭浆的步骤：灌浆孔的排布，采用三排二序施工方式进行，所述三排具体包括设置于防渗墙内的上游排和下游排，以及防渗墙外的下游排；灌浆孔的钻孔，采用加重泥浆护壁钻孔结合孔口封闭工艺进行分段式钻孔；灌浆孔的灌浆，采用套阀管灌浆结合钻灌交替灌浆的方式进行分段式灌浆，所述套阀管灌浆采用自下而上的分段卡塞法灌浆；钻灌交替灌浆采用自上而下分段式卡塞法灌浆。本发明灌浆方法适用于高水点，涌水，涌砂环境灌浆，灌浆效率高，对于多变地质适应能力强，灌浆后阻水幕形成完整，稳定，能够极大的降低，甚至消除因漏水，渗水带了的安全隐患。
