| titleOfInvention | ANTI-FILTRATION SCREEN |
| abstract | 1. The anti-filter screen, made in the form of a single soil-cement reinforced array, consisting of metal, non-recoverable injectors in the form of pipes with a diameter of 32-92 mm, which have blind and perforated parts, driven into pre-drilled wells located in staggered order in several rows, and an injection of clay-bentonite-cement or cement-sand mortar was introduced through the injectors into the soil under the load, and the distance between the injectors is inversely related to the filter coefficient ation saturated soil in place rabot.2 production. The anti-filter screen according to claim 1, characterized in that when working on the slopes, all injectors are tied by welding at ground level with round steel with a diameter of 10-40 mm or steel wire. The antifiltration screen according to claim 1, characterized in that when strengthening the dams enclosing the reservoirs, the screen occupies an area over the entire body of the dam, and the installation depth of the injectors is the sum of the height of the dam, the depth of the reservoir and 100-200 cm below the bottom of the reservoir. The anti-filter screen according to claim 1, characterized in that it is made double-row, or three-row, or continuous over the entire area of the reinforced water-saturated soil, and its depth exceeds the depth of the water-saturated soil by 100-150 cm. The antifiltration screen according to claim 1, characterized in that in one well there are several injectors of different heights, designed for cementation of different depth layers of soil, and the perforated part of each subsequent injector is located below the perforated part of the previous one, not cross |
