对老路改造过程中现状浅埋管线保护技术的改进

Improvement of the Technology for Protecting Current Shallow Buried Pipeline in the Process of Old Road Reconstruction

摘要:

目前，已建城市道路下面埋设着各种地下管线，特别是电力、电信、燃气、给水等管线，埋设比较浅，当后期老路改扩建或者新建道路与之相交时，老路开挖后需要对已铺设的管线进行保护。传统的保护措施存在安全隐患，改进后的保护措施不仅能消除安全隐患，还便于埋地管线的维修与养护，施工简单，快速高效，操作容易且绿色经济。通过目前已经实施的几条道路的使用情况来看，效果良好。

Abstract:

At present, a variety of underground pipelines are buried under the built urban roads. Pipelines of power, telecommunication, gas, water supply and others are buried relatively shallow underground. When the old roads are reconstructed and expanded or new roads are built, the existing pipelines need to be protected after excavation. There are potential safety hazards with traditional protection measures. The improved protection measures can not only eliminate the potential safety hazards, but also facilitate the repair and maintenance of buried pipelines. The construction is simple, fast and efficient. It is easy to operate and improves the development of green economy. Judging from the use of several roads that have been implemented so far, the results are good.
