Waterproof construction method for underground structure top plate
The invention provides a waterproof construction method for an underground structure top plate, which comprises the following steps of: performing steel bar construction and template construction on the top plate on an underground structure, and building a top plate frame; waterproof concrete is poured in the top plate frame to form a basement top plate; after the basement roof is maintained, a waterproof bonding layer is smeared on the upper surface of the roof; fine aggregate concrete doped with a mortar waterproof agent is poured on the surface of the waterproof bonding layer on the upper surface of the top plate to form a waterproof layer; and film covering maintenance is conducted, and waterproof construction of the basement roof is completed. The rigid waterproof layer and the concrete structure self-waterproof layer are adopted as two waterproof fortification of a water-based mud material, the two waterproof fortification are good in compatibility, the quality defects of water channeling, cold joints, honeycomb dog holes and the like are overcome from the source, concrete cracking is reduced, the concrete strength and the anti-seepage and waterproof performance are improved, the quality effect of one-time construction and lifelong maintenance-free is achieved, and the service life of the concrete is prolonged. And the project development and construction cost is reduced.
本发明提供了一种地下结构顶板的防水施工方法，包括以下步骤：在地下结构进行顶板的钢筋施工和模板施工，搭建顶板框架；在顶板框架内浇筑防水混凝土形成地下室顶板；对地下室顶板养护后，在顶板上表面涂抹防水粘合层；在顶板上表面防水粘合层表面浇筑掺加砂浆防水剂的细石混凝土形成防水层；覆膜养护，完成地下室顶板的防水施工。本发明采用刚性防水层与混凝土结构自防水同为水基泥材质的两道防水设防，二者相容性好，从根源上解决了“窜水”、“冷缝”、“蜂窝狗洞”等质量缺陷，降低混凝土开裂，提高混凝土强度和抗渗防水性能，达到了“一次施工，终身免修”的质量效果，同时降低项目开发施工成本。
