The rocket plough technique 6. Installing ductile cast iron pipes by the rocket plough technique 6.1 General For quite some time now, it has been the practice in rural areas for cables and plastic pipelines to be ploughed in from a drum provided there was no existing infrastructure or other obstacles along the path of the run. Where this is preferably done is along farm roads at the edges of areas used for agricultural purposes. The technique was successfully tried out for the first time using ductile cast iron pipes in 2000, as part of a research project, and it has now developed into a standard technique which has now been covered in the sets of rules issued by the DVGW and DWA. What is used for the installation of ductile cast iron pipes is the trailing plough procedure detailed in ATV DVWK Merkblatt M 1 0 [ .1] and DVGW Arbeitsblatt GW 32 (draft of /0 ) [ .2]. 6.2 A description of the technique A cavity is produced by a widening body shaped like the nose of a rocket at the bottom end of a ploughshare. A pipe string, which is attached to the widening body, is pulled into this cavity in the same stage of the operation. Fig. .1 shows the principle of the technique. So far it has been used with pipes of nominal sizes from DN 80 to DN 300. The machinery required consists of the traction vehicle (Fig. .2) and a plough (Fig. .3) carrying a ploughshare. To ensure that the vertical position of the path followed by the run remains constant when the profile of the terrain varies, the depth of penetration of the share can be controlled hydraulically.
