Construction method of elevator shaft sunken foundation
The method provides a construction method of an elevator shaft sunken foundation. The construction method comprises the following steps of a pile sinking step, specifically, sinking a precast pile with an embedded vertical stress rib into a soil body to a preset depth; a bottom plate placing step, specifically, placing a bottom plate on the top of the precast pile, and connecting the vertical stress rib of the precast pile with a second vertical stress rib of the bottom plate by adopting a mechanical connecting assembly; and a foundation frame body placing step, specifically, erecting a foundation frame body on the bottom plate, and connecting a first vertical stress rib of the foundation frame body with the second vertical stress rib of the bottom plate by adopting a mechanical connectingassembly. According to the construction method of the elevator shaft sunken foundation, it can be guaranteed that the foundation frame body and the bottom plate are high in strength, high in rigidity, and easy and convenient to connect, during transportation and installation, the labor input can be effectively reduced, the construction period is shortened, the construction cost is reduced, the construction quality can be guaranteed, and the connecting strength between the bottom plate and the foundation frame body is high.
本发明提供了一种电梯井下沉基础的施工方法，包括以下步骤：沉桩步骤：将预埋有竖向受力筋的预制桩沉入土体至预定深度；底板安放步骤：将底板下放于至预制桩的顶部，且采用机械连接组件连接预制桩的竖向受力筋和底板的第二竖向受力筋；基础框体安放步骤：将基础框体竖立于底板上，且采用机械连接组件连接基础框体的第一竖向受力筋和底板的第二竖向受力筋。本发明的电梯井下沉基础的施工方法，能够保证基础框体和底板强度高、刚度高、连接简便，便于运输安装过程中，能够有效降低劳动力的投入、缩短施工工期、降低施工成本，并且能保证施工质量，底板与基础框体之间连接强度高。
