正在兴起的非开挖技术——爆管法

Emerging trenchless technology—pipe bursting

非开挖技术在修复和替换天然气管道、污水管道和管线方面是一项迅速发展的技术.爆管是非开挖技术的一种方法,并且它是唯一的管道非开挖在线更换方法,它能够使掩埋的管道被一个完全新的管道所替换,同时,新管道可以独立行使现有管道的作用而且可以增加管径.通过介绍3种爆管系统,提供了关于爆管法的适用性、设计考虑因素和优点等方面的信息.

Trenchless technology is one of the rapidly developing areas in rehabilitation and replacement of gas pipes, sewer pipes and water mains. Pipe Bursting is one of the main methods of trenchless technology and it is the only renewal method of trenchless pipe rehabilitation in which a buried pipe can be replaced with a completely new pipe that functions independently of the existing line and permits the diameter of the new line to be increased. This paper presents an overview of three bursting systems and gives general information about the applicability, design considerations, and advantages of pipe bursting.
