Waterproof structure for deformation joint of open section of open cut tunnel
The invention provides an open-cut tunnel open section deformation joint waterproof structure, and relates to the field of building waterproof construction. Comprising a tunnel body, an enclosure structure, a middle-buried steel edge rubber water-stop belt, a first back pasting type rubber water-stop belt and a second back pasting type rubber water-stop belt. The tunnel body comprises side walls and a bottom plate, and a fine aggregate concrete protection layer, a first spraying rapid-hardening rubber asphalt waterproof coating layer, a non-woven fabric layer and a concrete cushion layer are sequentially arranged below the bottom plate. The enclosure structure is arranged on the outer side of the side wall, a middle-buried steel edge rubber water stop belt is arranged in each section of annular deformation joint along the tunnel body, and a first back-attached rubber water stop belt is arranged between the first spraying rapid-hardening rubber asphalt waterproof coating layer and the fine aggregate concrete protection layer. And a second back pasting type rubber water stop belt is arranged between the upstream side of the outer side of the annular deformation joint of the side wall and the second spraying rapid hardening rubber asphalt waterproof coating layer. According to the scheme, the problems that in the prior art, an open-cut tunnel is poor in waterproof performance, and water leakage is likely to occur can be solved.
本申请提供的一种明挖隧道敞开段变形缝防水结构，涉及建筑防水施工领域；包括隧道本体、围护结构、中埋式钢边橡胶止水带、第一背贴式橡胶止水带和第二背贴式橡胶止水带；隧道本体包括侧墙和底板，所述底板的下方依次设置有细石混凝土保护层、第一喷涂速凝橡胶沥青防水涂料层、无纺布层和混凝土垫层；围护结构设置在侧墙的外侧，沿隧道本体的各段环向变形缝内设置中埋式钢边橡胶止水带，第一喷涂速凝橡胶沥青防水涂料层与细石混凝土保护层之间设置第一背贴式橡胶止水带，侧墙的环向变形缝的外侧迎水侧与第二喷涂速凝橡胶沥青防水涂料层之间设置第二背贴式橡胶止水带，本方案能够解决现有技术存在的明挖隧道防水性能不佳，容易产生渗漏水的问题。
