新管道与在役管道由于各种原因,在一定的线位上并行、交叉的问题是不可避开的。在设计时就要考虑施工的可行性和在役管道的保护,来确定合理的线位间距。在施工时施工方要加强在役管道运营方的沟通,采取确实可行的保护措施,减少施工与运营间的壁垒。既要保护好在役管道,又能加快新建管道的施工进度。 The new pipeline and the pipeline in service due to various reasons, in a certain line of parallelism, the problem of cross is inevitable. In the design should consider the feasibility of construction and in-service pipeline protection, to determine the reasonable line spacing. During the construction, the construction party should strengthen communication between the operators in service and take practical and feasible protection measures to reduce the barriers between construction and operation. It is necessary to protect the pipeline in service, but also speed up the construction of new pipelines.
