High-rise building basement concrete self-waterproof construction process
The invention discloses a high-rise building basement concrete self-waterproof construction process, which belongs to the technical field of underground waterproof wall preparation, and sequentially comprises the steps of base layer treatment, template installation, structural rib installation, self-waterproof concrete preparation and pouring, template removal after solidification, maintenance treatment and the like. The concrete is prepared from the following components in parts by weight: 320 to 400 parts of coal ash, 40 to 80 parts of coal ash, 1350 parts of sand, 160 to 260 parts of water, 0.5 to 0.7 part of cellulose ether, 0.1 to 0.15 part of water reducing agent and 2 to 10 parts of waterproof additive. According to the construction technology, stable waterproof performance is provided for the basement building through casting of the self-waterproof anti-seepage concrete, and the anti-seepage performance of the concrete is improved by adding the waterproof additive on the basis of existing cement slurry.
本发明公开一种高层建筑地下室混凝土自防水施工工艺，属于地下防水墙制备技术领域，依次包括基层处理、模板安装、结构筋安装、配制自防水混凝土并浇筑、凝固后拆除模板并进行养护处理等步骤，所述自防水混凝土按重量份数计，具有如下的组分组成：320‑400份，粉煤灰40‑80份，砂1350份，水160‑260份，纤维素醚0.5‑0.7份，减水剂0.1‑0.15份，防水助剂2‑10份；本发明所述施工工艺通过通过自防水抗渗混凝土浇铸为地下室建筑提供稳定的防水性能，在已有的水泥浆料的基础上加入防水助剂提高混凝土的抗渗性能。
