laying head 10 is a hollow wing type subsoiler a plastic tape dispensing drum 15 is arranged above the laying head and a pipe dispensing drum 16 is arranged behing the tape dispensing drum the dispensing drums 15 and 16 can be positively driven or can run free and they can be provided with an adjustable brake depending on the quality of the materials to be laid one or more pipes that can be stored on one or more dispensing drums are generally made of plastic that is perforated for passing through the irrigation water from the pipe interior and formed as corrugated tube for easy replacement suitably irrigation pipe formed as plastic hose wound up flat as a tape can be used thus large quantity can be stored on a drum of small diameter such plastic hose can be made in a pair whereby the water distribution will be more homogeneous and ingrowth of the root can also be prevented by the use of such hose in the subsoil irrigation technology drain bodies are customarily implanted at equal distances from each other the plastic tape 14 from the drum 15 above the laying head 10 passes into the laying head 10 by winding off from the drum 15 and gradually being folded by guiding elements 24 the material of the tape 14 may be different from that of the pipe but inexpensive polyethylene is most suitable for the purpose the tape passes through guiding elements 11 in the hollow.
