The invention relates to hydraulic structures and can be used to change the direction of the stream of sharp turns of the watercourse channels, especially in mountainous conditions.

The purpose of the invention is to reduce the cost of construction by reducing the volume of industrial wood.

1 shows a half-pond, front view; figure 2 is the same, the view in the plan; in FIG. 3, view A in FIG. 1; figure 4 - node t in figure 1.

The semi-pond jet guide contains links of upgraded quivering ropes 1, the apical ends 2 of which are buried in the bank of the 3 channels of the watercourse, and the free ends of 4 are equipped with twig plugs 5 to exclude 1 stone mixture from the rope 6 (small stone, gravel, pebble, rubble) placed inside the ropes 1. Each rope 1 is transferred over the entire length at a predetermined distance from each other by wire or cable twist 7. The bottom layer of ropes 1 is laid on a layer of brushwood 8 or coniferous branches, the butt ends of which are laid along the current and step with a visor 9 over the front vertical row of ropes 1, absorbing the shock of overflowing water, excluding scouring and destruction of the bottom 10, and attached to the bottom 10 with lugs made in the form of anchors 11, with the ropes 1 of the lower and every second layers as well as the front vertical A pair of pairs and a pair of pairs are interconnected by flexible couplings 12 (cable, thick wires). Between the layers of ropes 1 there is a layer of 13 coniferous branches, brushwood or young trees, the commits of which protrude beyond the front vertical row of ropes 1 with peaks 14, absorbing the fall of overflowing water, excluding the destruction of the bottom of the watercourse. Along with layers 13 between the layers of ropes 1, stone loading 15 was laid, precluding the removal of the twigging layers 13 by water and creating massiveness and solidity of the entire semi-pond.

The work of the semi-pond consists in changing the direction of the stream (flow) of the water course, and its construction consists in the following. At the construction site, the semi-ponds temporarily divert the flow of the watercourse, pierce a nest for the apical ends 2 at the shore 3, level the bottom 10 of the channel and place a layer of brushwood 8 of a predetermined thickness with commas on the prepared place and make twigging ropes 1 on this layer they are on brushwood 8 layers with a given number of ropes 1, and the front (downstream) rope 1 is installed on a given deviation from the butt ends of brushwood 8,

the visor 9. The subsequent ropes 1 of the lower (first) layer are connected by flexible couplings 12 in pairs and a pair with a pair, and also attached to the bottom 10 of the water course by anchors 11, the following layer is laid on the bottom layer

layers of ropes 1 to a predetermined height, and between the layers lay a layer of 13 coniferous branches, which are protruding beyond the outer vertical row of ropes 1, creating peaks 14, while on layers 13 laid

stone loading 15. Each second layer, as well as a front vertical row of ropes 1 in pairs and a pair with a pair, are interconnected by a flexible link 12. A layer of brushwood is laid on the top layer of ropes 1

stone loading 15.

The introduction of the proposed semi-ponds reduces the consumption of industrial wood, allows the use of waste logging residues from thinning, clearing and

thinning, reduces transportation costs for transporting commercial wood and its harvesting, and also eliminates the use of loading and unloading mechanisms used in the loading and

unloading of commercial wood into rolling stock and laying it in a semi-pond. These benefits create a positive effect.

Claims (1)

Invention Formula A semi-pond jet guide containing a front wall installed within a watercourse, made of prefabricated elements, arranged in a vertical row and connected to each other, and twigging flooring with stone weights, located on the rear side of the front wall, differing from in order to reduce the cost of erection by reducing the volume of industrial wood, it is equipped with anchoring elements and flexible ties, while the prefabricated elements of the front wall are made of weaved twigging fascines in the form of ropes tied with wire twists and laid with layers of stone weights, the ropes of the lower layer are fixed to the bottom of the watercourse by anchoring elements, the lower and every second bottom layer, as well as the ropes of the vertical row of the front wall, are in pairs in a row and the pair with the pair in the layers are interconnected by flexible ties.
