Deep foundation pit outer wall integrated structure and construction method
The invention discloses a construction method for a deep foundation pit outer wall integrated structure. The construction method comprises the following steps that retaining wall constructional columns are replaced with socket type steel columns, a retaining wall is built on the outer side of a basement outer wall by using two layers of prefabricated brick tire membranes, a waterproof roll is paved between the two layers of prefabricated brick tire membrane retaining walls, opposite-pulling connecting pieces can be pre-embedded in the inner-layer prefabricated brick blank film retaining wall to fix the formwork, an enclosing wall for pouring the outer wall is formed, and therefore the space for pouring the outer wall is formed. According to the construction method, firstly, the situation that the construction amount is increased due to the fact that inclined struts are arranged before outer wall pouring can be avoided, the stability, pressure resistance and perpendicularity of the prefabricated brick forming die wall are enhanced through the steel columns, meanwhile, the number of the socket type steel columns is small, the distance between the supporting structure and the socket type steel columns is not limited by the small construction space any more when the distance is adjusted, and the distance between the supporting structure and the socket type steel columns can be adjusted to be less than 0.8 m; secondly, constructional columns such as the steel columns are flexible to assemble and disassemble, and the construction amount is greatly reduced; and thirdly, the construction method greatly reduces the dependence on the outer side space of the outer wall, so that the construction amount is greatly reduced. According to the construction method, the construction period can be greatly shortened, and the foundation pit design can be more flexible and more economical.
本发明公开了一种深基坑外墙一体式构造的施工方法，即用可承插式钢柱代替挡墙构造柱，在地下室外墙的外侧用两层预制砖胎膜砌筑挡墙，将防水卷材铺设于两层预制砖胎膜挡墙中间，内层预制砖胎膜挡墙可预埋对拉连接件来固定模板，构成浇筑外墙的围墙，从而形成外墙浇筑的空间。此方法，第一可以避免在外墙浇筑前设置斜撑增加施工量，利用钢柱加强预制砖胎膜墙体的稳定性和抗压性、垂直度，同时承插式钢柱的设置数量少，可使得支护结构与承插式钢柱调距时不再受到施工空间小的制约，支护结构与承插式钢柱的间距可调至0.8m以下；第二，钢柱等构造柱装拆具有灵活性，施工量大幅下降；第三，本施工方法极大的减少对外墙外侧空间的依赖，从而大大降低了施工量。本发明的施工方法不仅可以大大节约建造工期，而且可以让基坑设计更灵活更节约。
