Description

one

The invention relates to agriculture, in particular, to meliorate construction, and can be used to prevent water loss through filtration, for example, from irrigation canals by creating a filter, ion screens.

There is a known method of creating anti-filtration screens on irrigation canals by clogging, which involves supplying clogging solution through a perforated pipeline into the stream along the entire width of the channel.

However, with this method, the colmating solution does not penetrate deep enough into the bottom and slopes of the channel due to the difficulty of controlling the concentration of the solution, since it is fed into the flow of water moving through the channel. The purpose of the invention is to improve the quality of mudding. This is achieved by cutting at the bottom and the slopes of the channel in the longitudinal direction of the groove, into which clogging solution is fed followed by compaction of the kolmat soil, with the pipeline being laid along the perimeter of the channel.

FIG. Figure 1 shows the cross section of the channel with the means: placed in this way for carrying out this method; in fig. 2 - the same in terms of.

The Osun method is as follows.

Water is poured to the mixer 1 through the flexible pipe 2, which is attached to the mixer pipe 3 by a collar 3. The drainage of the final clogging solution, for example, a clayey sludge, is removed by means of a flexible irrigation pipe 4 with a diameter of 250-300 mm, from which the valve is fed in the furrows 5, depth 30-40 cm, cut along the longitudinal axis of the channel on its side slopes and bottom. The end part of the flexible pipe is closed by a lever clip 6.

To prevent the clay solution from leaking with water under the irrigation pipe and in the opposite direction from the water outlets, an oval bed with a roller from the ground is made in the ground, which also prevents the flexible irrigation pipe from non-rolling in the opposite direction. The dosed supply of the solution from the pipeline into each furrow was carried out using adjustable valves.

At a distance of 50-100 m from the irrigation pipeline 4, the flexible conveying pipeline 7 with a diameter of 350-400 mm is laid parallel to it. This pipeline is also laid in the oval bed, with two

Rollers from the ground are poured over its sides. Pipeline 7 closes the grooves and Prevents further advancement of the solution, as a result of which the solution fills the grooves to the desired level and is gradually absorbed into the ground. At this time, the supply of the solution through the valve. The irrigation pipeline is controlled by the polisher, which moves along the pipeline from the side opposite to the outlets.

After the absorption of the mud into the ground is stopped, the slopes and the bottom of the channel are intensified to an optimum moisture content, then the soil is compacted with the help of rollers and tampers.

Subject invention

1. Method of creating anti-filtration. screens on permanent irrigation canals, including a breakdown of the canal in the sections, laying in the intended section of a perforated BaiHHoro pipe 1bo (water for delivery and 1 distribution over the slopes and bottom of the channel of clogging solution, characterized in that, in order to gain a better quality of matting, and the slopes of the ca. iala are cut in the longitudinal direction of the furrow and serve in them clogging solution, followed by compaction of the kolmat soil.

2. The method according to p. 1.0 tl and h and you and the fact that the pipeline is placed around the perimeter of the channel.
