市政道路施工中既有地下管线保护措施研究

Research on Protection Measures of Existing Underground Pipelines in Municipal Road Construction

本文基于市政道路工程实例,对市政道路施工中既有地下管线保护措施进行了分析和研究,从而达到更好地保护既有管线的目的。针对不同类型的既有管道,采用经济可靠的保护方法,明晰拟建结构物与既有管线交叉分布情况,从保护方法的选择、保护方案的确定、保护制度的建立、施工过程的管理、管道恢复的措施等方面进行阐述,有利于维护市政道路地下管道管线正常运行,延长管线的使用年限,减少项目维修成本费用。

Based on the example of municipal road engineering,this paper analyzes and studies the protection measures of existing underground pipelines in municipal road construction,so as to achieve the purpose of protecting existing pipelines better.For different types of existing pipelines,this paper adopts economical and reliable protection methods to clarify the cross-distribution of proposed structures and existing pipelines,and expounds the selection of protection methods,determination of protection schemes,establishment of protection systems,management of construction process,and measures for pipeline restoration,which is conducive to maintaining the normal operation of underground pipelines on municipal roads,extend the service life of the pipeline and reduce the project maintenance cost.
