Waterproof construction method for underground structure outer wall
The invention provides a waterproof construction method for an outer wall of an underground structure, which comprises the following steps of: performing steel bar construction and template construction on the outer wall on a bottom plate of the underground structure, and building an outer wall frame; waterproof concrete is poured in the outer wall frame to form an underground outer wall; after the underground outer wall is maintained, the outer wall is cleaned and repaired; coating waterproof mortar on the outer wall to form a waterproof layer; and backfilling the fertilizer groove to finish the construction of the underground structure outer wall. 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外墙的防水施工方法，包括以下步骤：在地下结构底板上进行外墙的钢筋施工和模板施工，搭建外墙框架；在外墙框架内浇筑防水混凝土形成地下外墙；对地下外墙养护后，对外墙进行清理和修补；在外墙涂抹防水砂浆形成防水层；肥槽回填，完成地下结构外墙的施工。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。
