Method for installing steel columns within coverage range of inner support of deep foundation pit
The invention discloses a method for installing a steel column within the coverage range of an inner support of a deep foundation pit, which comprises the following steps: designing and preparing a hoisting portal frame, arranging a first carrying trolley below the hoisting end of the steel column, arranging a second carrying trolley provided with a turnover device below the other end of the steel column, hoisting the hoisting end of the steel column through the portal frame, rotating the turnover device, and hoisting the steel column. And aligning the upper section steel column and the lower section steel column by adjusting the portal frame, and loosening the steel columns at the moment, so that the steel columns are in place and temporarily fixed, and the like. The problems that installation of the main body structure steel columns within the coverage range of the multiple inner supports of the deep foundation pit is limited by space, and the installation difficulty is large are solved, the installation steps are simplified, and rapid installation is achieved.
本发明公开了一种深基坑的内支撑覆盖范围内的钢柱安装方法，包括设计并准备吊装门架、钢柱的起吊端下设置第一搬运小车，另一端下设置设有翻转装置的第二搬运小车、通过门架吊起钢柱的起吊端、翻转装置转动，使钢柱竖直、通过调整门架，使上下段钢柱对齐，此时松放钢柱，使其就位并临时固定等步骤。本发明解决深基坑多道内支撑覆盖范围内的主体结构钢柱安装受空间限制，安装难度大的问题，简化安装步骤，实现快速安装。
