Water-rich area open excavation section tunnel roof deformation joint waterproof structure and construction method thereof
The invention discloses a water-rich area open excavation section tunnel roof deformation joint waterproof structure and a construction method thereof, a roof comprises a roof first construction section and a roof later construction section, and a deformation joint is located between the roof first construction section and the roof later construction section; the waterproof structure comprises a deformation joint liner plate located in the deformation joint, and two embedded steel edge rubber waterstops are symmetrically arranged on the two sides of the middle of the deformation joint. The top of the top plate is provided with a back pasting type rubber waterstop, the back pasting type rubber waterstop covers the deformation joint, the outer side of the back pasting type rubber waterstop is sequentially provided with a waterproof reinforcing layer and an auxiliary additional outer waterproof layer, and the bottom of the deformation joint is provided with a water receiving groove. The waterproof effect of the deformation joint can be improved, the later operation safety of the tunnel is guaranteed, the cost increase caused by defect treatment is avoided, the construction specification requirement is met, the purposes of reducing the cost and improving the economic effect are achieved, and the problem of leakage of the tunnel roof deformation joint is solved.
本发明公开了一种富水区明挖段隧道顶板变形缝防水结构及其施工方法，所述顶板包括顶板先施工段和顶板后施工段，变形缝位于所述顶板先施工段与顶板后施工段之间；所述防水结构包括位于所述变形缝内的变形缝衬垫板，所述变形缝的中部两侧对称设有两条中埋式钢边橡胶止水带；所述顶板的顶部设有背贴式橡胶止水带，所述背贴式橡胶止水带覆盖所述变形缝，所述背贴式橡胶止水带的外侧依次设有防水加强层和辅助附加外防水层，所述变形缝的底部设有接水槽。本发明不仅能够提高变形缝防水效果，保证隧道后期运营安全，避免因缺陷处理造成的成本增加，符合施工规范要求，而且还实现了降低成本和提高经济效应的目的，解决了隧道顶板变形缝发生渗漏的难题。
