Deep foundation pit raft plate, water collecting well and elevator shaft integrated rapid construction method
The invention discloses a deep foundation pit raft, water-collecting well and elevator shaft integrated rapid construction method. The method comprises the following steps that a water-collecting well and elevator shaft local drop deep pit is excavated in the upper portion of a soil body at the bottom of a cement-soil mixing pile foundation pit, and side slopes are arranged on the periphery of the interior of the water-collecting well and elevator shaft local drop deep pit; laying a concrete cushion layer; a waterproof structure is laid on the concrete cushion layer, and raft reinforcing steel bars are installed on the waterproof structure; foundation column joint bars are installed at the position of a raft pre-cast strip, galvanized flow bar nets are installed on the two sides of a raft post-cast strip, a foundation water-collecting well elevator shaft inner formwork system is installed in a water-collecting well elevator shaft local deep pit, raft concrete is poured, and a reinforced concrete foundation is formed; removing the formwork system in the foundation water-collecting well elevator shaft to form the water-collecting well elevator shaft; and concrete is poured at the position of the raft post-cast strip, and a post-cast strip concrete structure is formed. The construction method has the advantage that integrated rapid construction of the deep foundation pit raft, the water collecting well and the elevator shaft is achieved.
本发明公开了一种深基坑筏板、集水井、电梯井一体化快速施工方法，包括以下步骤：在水泥土搅拌桩基坑坑底土体上部开挖集水井电梯井局部落深坑并在集水井电梯井局部落深坑内部四周设置边坡；铺设混凝土垫层；在混凝土垫层上铺设有防水结构，并在防水结构上安装筏板钢筋；在筏板先浇带处安装基础柱插筋，在筏板后浇带两侧安装镀锌流筋网，在集水井电梯井局部落深坑内安装基础集水井电梯井内模板体系，浇筑筏板混凝土，以形成钢筋混凝土基础；拆除基础集水井电梯井内模板体系，形成集水井电梯井；在筏板后浇带处浇筑混凝土，形成后浇带混凝土结构。本发明的优点是：实现了深基坑筏板、集水井、电梯井一体化的快速施工。
