Description

The invention relates to hydraulic engineering and can be used for laying film impervious screens. A device for placing a film screen is known, which includes a base machine, a film feed mechanism, a hollow L-shaped working body with a rotating drum and a stationary roller 1. The disadvantage of this device is the poor-quality connection of successively laid film canvases, which leads to water filtration through the film screen. A device is known for placing a film screen in the ground, including a base machine, a hydraulic actuator, a hollow earth moving body with horizontal and vertical blades, a feed mechanism for the sealant and a film, and a scraper with scrapers 2. The disadvantage of this device is the increased power consumption of the film screen laying, due to the need to create a trench along the seam. The aim of the invention is to reduce the energy consumption of laying a film screen. This goal is achieved by the fact that the device is equipped with a plowshare mounted on a horizontal knife of the working body, and the scraper scrapers are arranged with an inclination towards the plowshare. FIG. 1 shows a device, side view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. 2; in fig. 5 is a section of YYD in FIG. 2; in fig. 6 is a section d-d in FIG. 2. The device includes a base machine 1, a hydraulic actuator 2, a roll 3 with a film, a hollow earth-moving working body 4, a ploughshare 5, a mechanism 6 for supplying sealant 7, a drag 8. The drawing shows the previously laid film panel 10 and the stackable sheet 9. The device works as follows in a way. When the base machine 1 moves by means of a hollow working body 4, a cavity is cut into the soil, into which the film 9 is placed. At the same time, the working body 4 is installed so that the edge of the laid panel 9 is located above the edge of the previously laid panel 10 to prevent damage to the sheet 10 by the hollow working body 4 When moving, the ploughshare 5 forms a cavity in the ground, while the ground rises up by means of the plowshare. When moving, the rolling pin 8 displaces a layer of soil that separates the edges of the laid and laid film panels into the cavity formed by the ploughshare 5. The edge of the cloth 10 cleaned from the soil 10 by means of the mechanism 6 is supplied with a sealant 7. The film sheet 9 leaving the cavity of the working body 4 an overlap on the edge of the cloth 10 cleared from the ground and covered with a sealant. The overlap of the panels 9 and 10 is pressed by a layer of soil cut by a horizontal knife of the working body. After the curing of the sealant, water-imperoneum is formed stitched seam. The use of the invention will reduce the energy consumption of laying film screens.
