Description

The present invention relates to a device for spawning forests along mountainous rivers in trays made in the form of two, parallelly located / afloat at some distance from one another and behind the root linings. to the shores, a series of logs pivotally connected to each other in the longitudinal direction and rigidly in the transverse direction. Small mountain rivers present considerable difficulties for rafting forests on them, due to their considerable tortuosity, fast flow, large bottom slopes, the presence of rapids and drops, and a strong weediness of the channel.

The proposed invention has the aim to eliminate these drawbacks of mountain rivers with the help of a simple device and to make it possible to use them to make wood.

In FIG. 1 shows an exemplary longitudinal profile of a section of a mountain river; FIG. 2-plan of the proposed tray, FIG. 3 is a cross section; FIG. A 4-pattern matching of the dry-on tray.

Along the route of the intended “rafting route, a tray consisting of two rows of logs 4 is placed afloat (433)

interconnected in each row by means of a cable or wire 1, threaded through E drilled at the ends of the logs, and thus forming a hinge joint. In the transverse direction, rows of logs are connected between each other by brackets 2, by which the distance between rows of logs is kept constant along the entire length of the tray. To guide the tray in the plan, as well as to keep the tray from dragging it with water, the logs of the tray are fixed to the shores with 3 cable ties or wire rod, fixed to poles or nearby trees.

The two rows of logs so joined are a bottomless tray that serves to direct the float wood in the intended direction.

In steeply sloping river sections, the described guide trays are replaced with dry trays of conventional con-traction, which soften the gradient of the float path and match with the paved trays, as indicated in FIG. 1 and 4.

Prekhek iaobotenv.

1. The device for rafting wood on mountain rivers in trays is otlichayush, it is; That the trays are made in the form of two, parallel to each other, floating on some side over one another and behind the back to the shores.

p dssh logs, jointly connected to each other in longitudinal nahfav nvi and rigidly in the transverse. . 2. In the device according to claim 1, in Tselich, see steep slopes, dry trays of conventional construction, suspended from the required slope above the steep section of the river.
