随着城市建设的不断发展,非开挖技术被广泛运用于穿越公路、铁路、建筑物以及不满足开挖条件的市政管网工程中。非开挖技术在施工过程中相较于开挖技术而言具有产生的负面影响小、综合成本低、占地面积少、施工周期短、给环境带来的影响小等优势,因此非开挖技术的应用范围也越来越广泛。文中结合泉港区南部截污污水管道修复工程的实例对非开挖技术在市政管网修复中的应用做出探析。
With the continuous development of urban construction, trenchless technology is widely used in crossing municipal roads, railways, buildings and municipal pipelines that do not meet the requirements of excavation. Trenchless technology has the advantages of less negative impact, lower overall cost, less floor space, shorter construction period and less impact on the environment than the excavation technology in the construction process. Therefore, The application of technology is also more and more widely. In this paper, an example is given of the application of trenchless technology in municipal pipe network rehabilitation based on the example of the remediation sewage interception in the south of Quangang District.
