目前地下室外墙后浇带普遍采用防水回填前砌筑或用混凝土板封闭的方式。根据施工现场实际情况,借鉴地下室外墙后浇带提前封闭施工的成功经验,采取加强后浇带两侧支撑、混凝土盖板覆盖、防水回填土、支模、压力灌注自密实混凝土等措施,达到方便现场平面布置、形成安全消防通道等目的。本文重点介绍了后浇带封闭、防水施工、顶升配件制作拆除、混凝土浇注等施工工艺。
At present, the basement exterior wall with pouring tape generally used waterproof backfill before masonry or closed with concrete slab. According to the actual situation at the construction site, drawing on the successful experience of pre-sealing construction of the post-pouring belt in the basement wall, the measures such as strengthening the post-pouring with support on both sides, covering by concrete cover, waterproofing backfill, mold support and pressure perfusion self-compacting concrete Facilitate the site layout, the formation of fire safety and other purposes.
