River-crossing tunnel engineering waterproof construction method
The invention discloses a river-crossing tunnel engineering waterproof construction method. The method comprises the steps of waterproof construction of an open-cut section main structure and an accessory structure and waterproof construction of construction joints, deformation joints, pile heads, a through-wall pipe box, a dewatering well, latticed columns and the like. The open-cut section mainstructure and the accessory structure comprise waterproof construction of a bottom plate, a side wall and a top plate, and the prevention and drainage manner of adopting reinforced concrete self waterproof construction as the main and combining flexible waterproof layers is adopted. Waterproof construction of the construction joints, the deformation joints, the pile heads, the through-wall pipe box, the dewatering well, the latticed columns and the like is assisted by a water stop component to achieve waterproof construction, the construction joints are arranged at the construction subsectionsand the layering positions, and the deformation joints are arranged at the construction subsection positions. A tunnel obtained through the waterproof construction method is good in waterproof effectand high in quality.
本发明公开了一种过江隧道工程防水施工方法，它包括明挖段主体结构、附属结构防水、施工缝、变形缝、桩头、穿墙管盒、降水井、格构柱等的防水，明挖段主体结构、附属结构包括底板、侧墙、顶板防水，采用以钢筋混凝土自防水为主，柔性防水层相结合的防排方式；施工缝、变形缝、桩头、穿墙管盒、降水井、格构柱等的防水采用止水构件辅助防水，所述施工缝设于施工分段、分层处，变形缝设于施工分段部位，本发明通过该防水施工方法，得到的隧道防水效果好，质量高。
