FIELD: hydraulic engineering. SUBSTANCE: method for laying film curtain in ground includes parallel cutting of trench in ground by working deeper the transverse cutter and fitting film strips into formed space. Film strips are imparted trough profile in cross-section to form transverse partitions. Film strips are laid in two tiers and each film strip partially overlaps the preceding one under or above it. Device for laying film curtain in ground is articulated to base vehicle with hoisting device. Film laying mechanism has horizontal chamber with transverse cutter. Installed on horizontal chamber is vertical hollow wall and vertical longitudinal wall, with film roll holders installed above them. Installed on each wall is vertical cutter. Installed in horizontal chamber is turning shaft, and two slot guides connected with ground holders installed on rear end. Each longitudinal tie-rod is hinged with respective levers of hoisting device. EFFECT: higher efficiency. 5 cl, 16 dwg
