Elevator shaft foundation pit construction method
The invention belongs to the technical field of building construction, and discloses an elevator shaft foundation pit construction method which comprises the following steps: S1, constructing an elevator shaft foundation pit support at the bottom of a foundation raft foundation pit by using steel sheet piles according to the design position of an elevator shaft; s2, an elevator shaft foundation pit is excavated according to the elevator shaft design position; s3, a first leveling layer is constructed on the vertical face, facing the elevator shaft foundation pit, of the steel sheet pile; and S4, waterproof coiled materials are pasted on the vertical face, facing the elevator shaft foundation pit, of the first leveling layer. According to the elevator shaft foundation pit construction method, the steel sheet piles are used as elevator shaft foundation pit supports, the problem that potential safety hazards exist when the elevator shaft foundation pit is excavated at the bottom of the foundation raft foundation pit in a sloping mode is solved, and the waterproof effect of the elevator shaft foundation pit supports is guaranteed; the problems that the waterproof guide wall is high in cost, large in difficulty and easy to collapse when being built between the elevator shaft foundation pit and the side slope supported by the elevator shaft foundation pit are solved.
本发明属于建筑施工技术领域，公开了一种电梯井基坑施工方法，包括如下步骤：S1、根据电梯井设计位置在基础筏板基坑底部以钢板桩施作电梯井基坑支护；S2、根据所述电梯井设计位置开挖电梯井基坑；S3、在所述钢板桩朝向所述电梯井基坑的立面上施作第一找平层；S4、在所述第一找平层朝向所述电梯井基坑的立面上粘贴防水卷材。本发明的电梯井基坑施工方法，使用钢板桩作为电梯井基坑支护，避免在基础筏板基坑底部放坡开挖电梯井基坑存在安全隐患的问题，保证电梯井基坑支护的防水效果，解决了在电梯井基坑与电梯井基坑支护的边坡之间砌筑防水导墙成本高、难度大且易倒塌的问题。
