In order to lay down a pipeline, which consists of socket pipes (9), a device which consists of a frame with two side walls (1) can be used. On the outside of the side walls (1) there is mounted a number of engines (7) which can lead an intermediate cross member (2) to the front and to the rear of the frame. Moreover there is in the front of the frame mounted a profile cutter (6) which can be led down into the underlying layer and excavate a bearing (8) for the socket. By means of this device an excavation can be made and a pipeline, which is supported in its full length, laid down. In this way even the strictest demand to laying down a pipeline can be complied with. |
