有限空间半逆作法施工中的综合管线原地保护技术

Integrated Pipeline In-Place Protection Technology During Semi-Reversed Construction in Confined Space

广州宏城广场综合改造工程二期基坑在有限的空间条件下,需解决施工空间不足、综合管线原地保护等一系列问题。针对上述存在的施工难点,对扩展施工可用场地、综合管线原地保护等问题展开一系列研究,取得了良好的效果,可供类似工程借鉴。

Under finite special condition, the reconstruction project Phase Ⅱ of Guangzhou Hongcheng Plaza foundation pit should solve a series of difficulties, such as lack of construction space and integrated pipeline in-place protection. Therefore, a series of research was carried out to solve the construction difficulties including the construction site extension and the integrated pipeline in-place protection, which have achieved good effect and can provide references for similar projects.
