地下管线非开挖检测技术的应用

Application of Non-excavation Detection Technology in Underground Pipeline

地下管线属于隐蔽工程,数量庞大且种类繁多。随着城市的发展,由于地下管线问题引起的大雨内涝、管线爆裂、路面塌陷等事件频繁发生,严重影响人民生活生产安全,已经成为智慧城市建设的痛点和难点。本文以广州典型区域为背景,在管线调查及数字测图的基础上,运用非开挖检测技术对地下管线存在的问题进行检测、判断,可为城市地下管线的修复或更新提供准确可靠的数据及技术报告,为城市建设提供重要的参考数据,为应急防灾,预警预报提供有力支持。

Underground pipelines belong to concealed projects,which have a large number and a wide variety of types.With the development of the city,heavy rain and water-logging,pipeline burst,road collapse and other events caused by underground pipeline problems occur frequently,seriously affecting the safety of people’s lives and production,which has become the pain and difficulty of the construction of intelligent city.Based on the survey of pipelines and digital mapping in a certain area of Guangzhou,this paper uses trench less detection technology to detect and judge the existing problems of underground pipelines,which can provide accurate and reliable data and technical reports for the repair or renewal of urban underground pipelines,provide important reference data for urban construction,and provide strong support for emergency disaster prevention and early warning and prediction.
