Construction process for reconstructing waterproof layer of underground engineering structure
The invention discloses a construction process for reconstructing a waterproof layer of an underground engineering structure, which comprises the following steps: surveying a construction surface before construction, forming a micro grouting hole, arranging a grouting needle on the inner side of the grouting hole, and fixing the grouting needle by using rapid setting cement; the non-dispersible grouting material and the silane modified polyether water-cured grouting material are respectively blended, mixed and stirred. The invention aims to provide a material which is punched through an existing underground engineering structure, and a waterproof material is injected into the upstream face of the structure according to a design process, so that the injected material forms a waterproof layer on the upstream face of the existing underground engineering structure, and water in a stratum is prevented from permeating into structural concrete any more; according to the silane modified polyether water curing grouting material, a waterproof layer attached to the upstream face of the structure is formed on the outer surface of the structure, so that flexible water prevention is added outside the structure, a water source is prevented from permeating into structural cracks, and it is ensured that the phenomenon of secondary leakage does not occur.
本发明公开了一种地下工程结构再造防水层施工工艺，所述包括以下步骤：所述在进行施工前需要对施工面进行勘察，并且开设微型注浆孔，将注浆针头设置在注浆孔的内侧，并且利用快速凝固水泥对注浆针头进行固定；所述将不分散注浆材料和硅烷改性聚醚水固化灌浆料分别进行调配混合搅拌。本发明所述目的在于提供材料采用打穿既有地下工程结构，将防水材料按设计工艺注入到结构迎水面，使得注入材料在既有地下工程结构迎水面形成防水层，从而阻隔地层中的水不再渗入结构混凝土中，硅烷改性聚醚水固化灌浆料是在结构外表面形成一层贴合于结构迎水面的防水层，使结构外增加柔性防水，阻止水源渗入结构裂缝之中，从而确保不会出现再次渗漏现象。
