Waterproof construction method for underground structure bottom plate
The invention provides a waterproof construction method for an underground structure bottom plate. The waterproof construction method comprises the following steps that foundation original soil is tamped to form a foundation of an underground structure; a waterproof cushion layer is poured on the foundation; steel bar engineering construction and formwork engineering construction are sequentially conducted on the waterproof cushion layer; bottom plate waterproof concrete is poured, the vibrating time is 10-30 s, and layered pouring is conducted; the waterproof concrete is cured for more than or equal to 14 days after being finally set, and the underground structure bottom plate is formed. 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底板的防水施工方法，包括以下步骤：地基原土夯实形成地下结构的地基；在所述地基上浇筑防水垫层；在所述防水垫层上依次进行钢筋工程施工和模板工程施工；浇筑底板防水混凝土，振捣时间为10‑30s，分层浇筑；所述防水混凝土终凝后进行养护≥14天，形成地下结构底板。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。
