摘要
在中心城区改造项目的深基坑施工过程中,时常会遇到重要管线穿越基坑且无法迁移,围护结构与管线碰撞、深层土位移导致管线变形等一系列管线保护的难题,为此,以嘉兴中山路改造市政工程为例,详细介绍了重要电力高压管线及国防光缆横穿通道基坑的保护方法。所总结的经验可为今后同类工程提供参考。
During the construction of deep foundation pit in the reconstruction project of central urban area,a series of pipeline protection problems are often encountered,such as the important pipelines passing through the foundation pit and unable to be relocated,the collision between retaining structure and pipeline,and the deformation of pipeline caused by deep soil displacement.Therefore,taking the municipal reconstruction project of Zhongshan Road in Jiaxing as an example,the protection methods of important power high-voltage pipelines and national defense optical cables crossing the channel foundation pit are introduced in detail.The experience summarized can provide reference for similar projects in the future.
