Abstract

FIELD OF THE INVENTION The invention relates to hydraulic engineering and land reclamation construction. The purpose of the invention is to increase the efficiency of the canal operation by preventing violations of the hydrogeological regime of the adjacent territory. In the implementation of the channel construction method, vertical slots 1 are first developed on both its sides with their deepening in the water stop 2. Then isolated containers 3 with charges of 4 explosives and sand-gravel mixture 5 are immersed in the slots. After this, slots 1 are filled with an anti-filtration material 6 and form the channel 7 of the channel, for example, with fastening 8 of its slopes 9 and bottom 10. Then charges 4 explode to form filtering windows in the impervious material 6. Insulated containers 3 are made with a width smaller than the width of the slots 1, and fix them along the axis of the slits 1 between the bottom of the bottom of the channel 10 and the surface of the water-proof 2. 3 Il.

Description

Fig, 1

The invention relates to hydraulic engineering and land reclamation construction and can be used when laying canals in flooded soils.

The purpose of the invention is to increase the operational efficiency of the channel by preventing violations of the hydrogeological regime of the adjacent territory.

Fig. 1 shows a channel to form a channel, a cross section; Fig. 2 - the same, after formation of the channel; in FIG. 3, node I in FIG. one.

The method of building a channel includes making vertical slots 1 on both sides of the channel with deepening into the water layer 2, immersing the insulated tanks 3 with charges of 4 explosives and sand-gravel 5 in them, filling the slots 1 with anti-filtration material 6, forming the channel of the channel 7, for example, by fastening 8 its slopes 9 and bottom 10, blasting charges to form filtering windows 11 in an anti-filter material. When this isolated container 3 is made wide, smaller width, slots and fix them along the axis of the slots 1 between the bottom of the bottom 10 of the channel and the surface of the water-resistant 2.

The slits 1 are formed by known drilling or grab mechanisms to develop vertical trenches with protection from collapse by feeding as the clay slurry with collisional properties-1 goes deeper into the slit 1, which is displaced when filled with an anti-filtration material 6. used are clay, clay mortars or special concretes. Insulated container 3 can be made of plastic bags.

Charging of charges 4 can be carried out by firing using a detonating cord 12, ignited on the surface.

After fencing the canal construction zone 1, on the one side of the channel, the level of groundwater rises to level 13, and on the other, decreases to level 14 (depending on the direction of movement of groundwater).

After the formation of the cavity of channel 7 and the subsequent blasting of charges 4, levels 13 and 14 are almost equalized and the natural UPV is restored.

Claims (1)

The number of filtering windows 11 along the channel path is determined based on the required degree of alignment of levels 13 and 14, since the more windows there are 11, the closer these levels will be to the natural level. Claims of Invention A method of building a canal in flooded soils, including making vertical slots on both sides with depth into the aquifer, filling them with anti-seepage material and forming a channel channel that differs in that. that, in order to increase the channel operation efficiency by preventing disturbance of the hydrogeological regime of the adjacent territory, before filling the slots with an impervious material, insulated containers with explosive charges aeaiecTB and sandy gravel are embedded in them and fixed with a width less than the width of the slots and fixed along the axis of the gap between the bottom of the channel bottom and the surface of the water column, and after the channel channel is formed, charges explode to form filter windows in the impervious material. 731 I // ;.: --- v: v -o o ° o k   -. i L: -. i: m.:.
