DESCRIPTION:
BRIEF SUMMARY
This invention relates to a method of draining wetland as, for example, peatland, mosses, marshes and the like, as well as forest land and arable land, and to a device for carrying out the method.
Apart from manual ditching, lands of the aforesaid kind heretofore have been drained exclusively by excavating machines of various types, by which normally only lengths of about 3 m can be ditched whereafter the machine has to be moved and re-positioned. For each such length the bucket of the machine must be filled and emptied at least six times. On wetland the excavating machine must be moved and re-positioned more frequently, to prevent the machine from sinking down and getting stuck. It is obvious that draining with excavating machines is complicated, tedious and thereby expensive. Furthermore, with this conventional ditching method soil or peat masses are obtained which not in all cases can be placed on the ditch edges, but must be carried away. In such cases the drainage costs increase substantially.
In ditches especially in wetland the sides often collapse due to the increase in pressure caused by the masses placed on the ditch edges. The ditches thereby are filled with mud relatively quickly and become more shallow. It is not possible, either, to drain very wet land by means of excavating machine, and such ditching normally must be carried out manually.
The present invention, therefore, has as and object to provide a method and a device for ditching, which do not show the aforesaid disadvantages, but are much more rapid and rational and render it possible to ditch without producing any soil masses, which have to be stacked or transported away. Further, the present invention renders it possible to ditch in such wetlands, which do not carry, for example, an excavating machine.
These object and others are achieved in that the method and the device according to the present invention.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention is described in greater detail in the following, with reference to the accompanying drawings, in which
FIG. 1 is a view of an embodiment of the invention,
FIGS. 2 and 3 are views of the same embodiment seen from above and, respectively, from the front,
FIG. 4 is a partial sectional view of an enlarged detail of the device according to the invention,
FIG. 5 is a view of a modified application of the invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The device according to the embodiment shown in FIGS. 1-4 comprises a V-shaped frame 1 with smooth sides 2 of a low-friction material, for example sheet metal. The sides 2 are arranged symmetrically with respect to an axial line of the frame 1. The sides 2 though shown to be parallel in the machine direction along their entire length may at their rear portion be formed with inclination, i.e. may be deflected inward or be given slightly convex arc-shape, in order to reduce to the greatest possible extent the counterforces against advancing which arise especially in wet lands.
The frame 1 further is formed or provided with a plough-like forward portion 3 with a generally V-shaped horizontal cross-section, the forward free boundary edge 4 preferably is formed like a cutting edge, and which forwardly is closed vertically and can be straight or undercut to arc-shape, as shown by dashed lines 5 in FIG. 1, or be straight or overcut to arc-shape, as shown by fully drawn lines 6 in FIG. 1, or be vertical. The smooth sides 7 of the forward portion preferably consist of the same material as the frame sides 2. The V-shape of the frame can be made wider or narrower than shown in the drawings and thereby be adjusted to the cross-sectional shape of the drain to be ditched. At its rear portion, the frame 1 can be formed or provided with a portion similar to the forward portion 3, so that the device can be advanced in one direction or the other without having to be turned around. Along the narrow, preferably slightly rounded lower surface of the frame 1, a wear bar 8 is located which, of course, also extends over the forward portion 3 and po
