The Pipe Express Method

What Does The Pipe Express Method Mean?

管道表达方法是半桥，环保的管道安装方法，有助于加速管道结构。它是一个相对较新的方法，可以在近达1000米长到1000米的近端安装管道的近表面安装，直径为800毫米至1500毫米。

The pipe express method was developed by Herrenknecht, and set new standards for the installation of pipelines over long distances.

Trenchlesspedia Explains The Pipe Express Method

The pipe express method combines the use of the tunnel boring machine (TBM) and a compact trenching unit. A launch pit is dug at the point where the pipe will enter the soil and houses a pipe thruster and TBM. The trenching unit is attached to a buggy that makes a narrow trench (width approx. 40 cm) on the soil.

The actual tunnel is below the trench and is excavated by the TBM. The excavated soil from the TBM is brought up by the trenching unit and is backfilled behind the machine as the installation progresses.

The pipe thruster pushes the pipe as well as the TBM through the soil till the installation is complete and the unit exits at the receiving pit.

该管快递方法消耗大约70％的地面空间，而不是开放式挖沟，整个过程遥控控制和由训练的操作员引导。

The pipe express method was first used in the Netherlands in November 2012 for installing a 48”, 1600 feet gas pipeline.
