Water-rich stratum open cut underground structure composite waterproof structure and construction method
The invention discloses a water-rich stratum open cut underground structure composite waterproof structure and a construction method. The composite waterproof structure comprises a bottom plate composite waterproof structure, a side wall composite waterproof structure and a top plate composite waterproof structure which are used for integrally arranging a main body structure in the middle in a surrounding mode, the bottom plate composite waterproof structure sequentially comprises a soil layer, a cement mixing pile, a concrete cushion layer, a first HDPE waterproof sheet and a first rapid hardening waterproof coating from bottom to top, the side wall composite waterproof structure sequentially comprises a high-pressure jet grouting pile, an enclosure structure, a base plane leveling layer, a second HDPE waterproof sheet and a second rapid hardening waterproof coating from outside to inside, and the top plate composite waterproof structure sequentially comprises a backfill soil layer, a concrete protection layer and a third rapid hardening waterproof coating from top to bottom. According to the composite waterproof structure, the advantages of several common waterproof methods are integrated, the disadvantages of the common waterproof methods are made up, the waterproof reliability can be greatly improved on the premise that the waterproof engineering operation cost is slightly improved, and the repair and maintenance cost in the operation period is greatly reduced.
本发明公开了一种富水地层明挖地下结构复合防水结构及施工方法，该复合防水结构包括将主体结构整体围设于中间的底板复合防水结构、侧墙复合防水结构和顶板复合防水结构；其中，底板复合防水结构由下至上依次包括土层、水泥搅拌桩、混凝土垫层、HDPE防水片材一、速凝防水涂料一；侧墙复合防水结构由外至内依次包括高压旋喷桩、围护结构、基面找平层、HDPE防水片材二、速凝防水涂料二；顶板复合防水结构由上至下依次包括回填土层、混凝土保护层、速凝防水涂料三。本发明复合防水结构在整合了几种常见防水方法的优势的同时，又弥补了各自的劣势，可在小幅提升防水工程作业成本的前提下大幅提高防水可靠度，大幅降低运营期的维修、维护费用。
