Waterproof system for cover and excavation top-down subway station bottom plate and construction method of waterproof system
The invention discloses a waterproof system for a cover and excavation top-down subway station bottom plate and a construction method of the waterproof system. The waterproof system comprises a cushion layer chamfer, a film spraying waterproof layer and a bottom plate waterproof protection layer. The cushion layer chamfer is arranged at the internal corner of the enclosure structure and the bottom plate cushion layer, and the section of the cushion layer chamfer is of a triangular structure. The sprayed film waterproof layer covers the surfaces of the enclosure structure, the cushion layer chamfer and the bottom plate cushion layer; the spraying film waterproof layer is an acrylate spraying film waterproof layer; wherein the film spraying waterproof layer located on the surface of the bottom plate cushion layer serves as a bottom plate waterproof layer; a bottom plate waterproof protection layer is arranged on the surface of the bottom plate waterproof layer, the bottom plate structure is arranged on the surface of the bottom plate waterproof layer, and the side wall structure is arranged on the surface of the side wall waterproof layer; according to the invention, the good ultimate elongation percentage of the acrylate spraying film waterproof layer is utilized, so that the waterproof system has stronger self-healing capability, the integrity of the concrete structure is ensured, the construction efficiency is improved, the construction period is shortened, and the engineering cost is saved.
本发明公开了一种用于盖挖逆作地铁车站底板防水系统及其施工方法，包括垫层倒角、喷膜防水层及底板防水保护层；垫层倒角设置在围护结构与底板垫层的阴角处，垫层倒角的截面为三角形结构；喷膜防水层覆设在围护结构、垫层倒角及底板垫层的表面；喷膜防水层采用丙烯酸盐喷膜防水层；其中，位于底板垫层表面的喷膜防水层作为底板防水层；底板防水层的表面设置有底板防水保护层，底板结构设置在底板防水层的表面，侧墙结构设置在侧墙防水层的表面；本发明利用丙烯酸盐喷膜防水层良好的极限延展率，使防水系统具有较强的自愈能力，保证了混凝土结构的整体性，提高了施工效率，减少了施工工期，节省了工程成本。
