Foundation pit steel support installation method
The invention provides a foundation pit steel support installation method which comprises the steps that a foundation pit is excavated to a preset position, supporting pieces are installed on the two sides of a foundation pit enclosure structure, and a first supporting structure and a second supporting structure are arranged at the joint position corresponding to two sections of steel supports at intervals; the first section of steel support is placed on the first supporting structure and the adjacent supporting piece, and if the settlement condition of the first supporting structure meets the preset requirement, the position of the end of the first section of steel support is adjusted; a second section of steel support is placed on the second supporting structure and the other supporting piece, if the settlement condition of the second supporting structure meets the preset requirement, the position of the end of the second section of steel support is adjusted, and the first section of steel support is connected with the second section of steel support; and the second section of steel support and the foundation pit support structure are fixed through a steel wedge. According to the method, sectional rapid installation of the steel support is achieved, space limitation is avoided, the hoisting capacity requirement and the hoisting space requirement of hoisting equipment are reduced, and the installation efficiency of the steel support is improved.
本发明提供了一种基坑钢支撑安装方法，包括：将基坑开挖至预设位置，在基坑围护结构的两侧安装支撑件，并在对应于两节钢支撑的接缝位置处间隔地设置第一支撑结构和第二支撑结构；将第一节钢支撑放置于第一支撑结构与相邻的支撑件上，若第一支撑结构的沉降情况满足预设要求时调节第一节钢支撑端部的位置；将第二节钢支撑放置于第二支撑结构与另一个支撑件上，若第二支撑结构的沉降情况满足预设要求时调节第二节钢支撑端部的位置，并将第一节钢支撑与第二节钢支撑连接；第二节钢支撑与基坑围护结构之间通过钢楔固定。本发明实现了钢支撑的分节快速安装，不受空间限制，降低了吊装设备的吊装能力需求及吊装空间需求，提高了钢支撑的安装效率。
