Mounting method of foundation pit profile steel combined support
The invention discloses a mounting method of a foundation pit profile steel combined support, and aims at providing a construction method of a foundation pit profile steel combined support, wherein the construction method can effectively solve the problems that profile steel support beams of foundation pit inner supports on non-top layers in deep foundation pits are hard to hoist and inconvenientto mount. The mounting method of the foundation pit profile steel combined support adopts profile steel combined support mounting equipment to achieve construction, the profile steel combined supportmounting equipment comprises a main crane, in-pit cranes and multiple suspension assemblies, and each suspension assembly comprises two circular lifting rings. After the foundation pit is excavated downwards to the set elevation, a second profile steel support beam to an Nth profile steel support beam below a first profile steel support beam can be lowered to the design elevation through the in-pit cranes, mounting is completed, the second profile steel support beam to the Nth profile steel support beam are supported in the foundation pit oppositely, and hoisting and mounting of the profile steel support beams of foundation pit inner supports on non-top layers are convenient after foundation pit excavation.
本发明公开了一种基坑型钢组合支撑的安装方法，旨在提供一种能够有效解决深基坑内的非顶层的基坑内支撑的型钢支撑梁存在吊装困难，安装不便的问题的基坑型钢组合支撑的施工方法。基坑型钢组合支撑的安装方法采用型钢组合支撑安装设备进行施工，型钢组合支撑安装设备包括主吊机、坑内吊机及若干悬挂组件，悬挂组件包括两个呈环形的吊环。待基坑往下开挖至设定标高后，就可以通过坑内吊机将第一道型钢支撑梁下方的第二至第N道的型钢支撑梁下放至计标高并完成安装，将第二至第N道的型钢支撑梁对撑在基坑内，使基坑开挖后非顶层的基坑内支撑的型钢支撑梁的吊装与安装方便。
