Reverse construction method upstream face waterproof system reconstruction deep guide hole forming construction technology
The invention provides a reverse construction method upstream face waterproof system reconstruction deep guide hole forming construction technology. According to the reverse construction method upstream face waterproof system reconstruction deep guide hole forming construction technology, the problem of water seepage caused by sealing failure of an original waterproof layer of an underground building is solved in the mode that waterproof materials are poured into the deep guide holes at high pressure. The method mainly comprises the steps of placing a casing and a grouting pipe in primary drilling, and fixing a lower casing; conducting secondary drilling, pouring the waterproof material, taking out an upper sleeve, backfilling and drilling, and recovering the building surface layer.
本发明提供了一种逆作法迎水面防水体系重构深导孔成型施工工艺，通过深导孔高压灌注防水材料的方式，解决地下建筑因原防水层密封失效渗水问题。主要步骤包括一次钻孔放置套管和注浆管，固定下套管；二次钻孔，灌入防水材料，取出上套管，回填钻孔，恢复建筑面层。
