摘要
为满足生产、生活需要,在城市地下空间已经敷设了大量排水、燃气、电力等各类管道。当原有管道与新的地下空间利用需求相冲突时,就需要废除原有管道。目前管道废除主要采用开槽将管道挖除后再回填的办法,但城市中大部分管道位于道路下方,开挖废除法对交通影响大,且对于涉及文物保护等不允许开挖的情况不适用。而非开挖技术则可很好地解决以上问题,结合某道路下管道废除工程,对反向拔管技术在管道非开挖废除工程的应用进行阐述,以期能为其他从业者提供重要参考经验。
In order to meet the needs of production and life,a large number of drainage,gas,electricity and other kinds of pipelines have been laid in the urban underground space.When the original pipeline conflicts with the demand of new underground space utilization,it is necessary to abolish the original pipeline.At present,the main method of pipeline abolition is to excavate and then backfill the pipeline.However,most of the pipelines in the city are located under the road.The method of excavation and waste removal has a great impact on the traffic,and it is not suitable for the situation that the excavation is not allowed for cultural relics protection.The trenchless technology can solve the above problems.The application of reverse pipe pulling technology in Trenchless Pipeline Engineering is described,in order to provide important reference experience for other practitioners.
