Ploughing

Ploughing

The cable/pipe insertion part of the laying plough is set in the start groove with the required laying depth of up to a maximum of 2.20 m. Subsequently, the systems are laid in the insert built In accordance with the special requirement criteria and the ploughing process can start.

The performance features of the Schnell Special Laying Plough FSP 22, used with laying depths of up to 2.20 m and traction’s of the winch vehicle of up to a maximum of 200t, allow very demanding constructions and use under difficult conditions.

Monitoring of the laying depth

For non-monitored ploughing, obstacles in the ground, for instance, can result in lower depths. However, lower depths represent a safety and damage risk for high-voltage cables and must be avoided by all means.
By recording the section topography, the prescribed laying depths can be observed and monitored or documented. Lower depths are, of course, also recorded and must be rectified with the methods of open construction, e.g. when finding rock, erratic blocks, etc. The control of the depth is performed by the plough operator on the basis of visual information via the deviation of the depth from the target value and/or corresponding control commands from the mobile control position. The documentation can be issued digitally and/or in the form of length cross sections. The data are recorded every second.

Laying plough information

1. Laying groove
After laying, when restoring the surface, the laying groove is closed to about half. The earth forms a cavity above the medium.
It is filled up with fine parts by the rain water dripping through. The laid medium now lies on the laying ground sanded in.

3. Insertion element and sword shoe

The insertion element automatically adjusts horizontally and vertically. The adjustable sword shoe controls the laying depth exactly and allows a quick depth adjustment.

Alternative Methods

We also offer the services of a Komatsu D655 Vibratory Plough.
The Komatsu is able to install two coils of duct / pipe simultaneously at a max depth of 1.2m.
In areas that does not consist of mainly soft soil, we recommend that a Ripper do an initial rip in front of the Plough. This allows the Plough to operate under less tension and also delivers a faster installation speed.

Compaction

In order to compact the plough line sufficiently to avoid sagging or erosion, various compaction methods are available. The method and size will depend on the specification and conditions on site.
