3.1. The invention relates to land improvement, namely, devices for forming impervious concrete channel facing. A known vibrating mold for concreting channels, including a frame with supporting skis, a guide part with a working surface in the form of cylindrical rollers of various diameters, a distribution bunker, a vibrating bar and a smoothing bar, vibro-cutter 1. The disadvantages of this vibro-shape are considerable structural and working mass, the need to move a significant amount of concrete mix, the possibility of using only the post., finishing the soil base of the channel. A vibrating mold for concreting channels is also known, comprising a frame, a bunker, the front wall of which is made with stripping slopes and bottom blades having dimensions corresponding to the channel profile, and forming devices 2. A disadvantage of the known vibroform is that part of the soil being cut by stripping blades is removed with the help of an excavator, and this increases the labor costs for channel concreting. The purpose of the invention is to reduce labor costs. The goal is achieved by the fact that, in a vibrating form containing a frame, a bunker, the front wall of which is made with stripping slope idon knives having dimensions corresponding to the channel profile and shaping devices. a cleaning knife is provided with augers placed parallel to the sloping cleaning blades, the bunker is made with a slit located along the channel profile, while its rear wall is equipped with a blade distributor of concrete mix and is installed on the frame at an angle to the horizon. FIG. 1 shows the device, section, side view; in fig. 2 - the device, front view; in fig. 3 - the bottom part of the front wall of the hopper, type A in FIG. one; in fig. 4 is a section BB in FIG. 1. In the front of frame 1 (Fig. 1), a hopper 2 is placed to receive and distribute the concrete mix around the channel perimeter and a wall 3 is fixed to move the vibrating mold. The hopper 2 is made in the form of a slit inclined to the cross section flat along the entire perimeter of the channel. The installation angle of the hopper to the base of the channel is 30-60 °. On the front wall 4 of the bunker (Fig. 2), along the perimeter of the channel, bottom 5 and side 6 wiper blades are installed for final profiling of the soil foundation of the channel. Two transport augers 7 with shells are mounted along the side knives at the bend of the back of the knife (Fig. 4) to move the soil cut by the blades from the bottom and slopes of the channel to the berm. The bottom cleaning knife 5 (Fig. 3) for improving the conditions for cutting the soil and moving it to the augers is made lancet with the central part raised (similar to the cultivator leg). Under the bottom knife there is a supporting base 9 (Fig. 1). On the rear wall (bottom) 10 with the forming shelves 11 is installed paddle distributor 12 of the concrete mix around the perimeter of the bunker. The distributor 12 and the transport screws 7 are driven from the traction tractor through the shaft line 13 and chain transmissions. A sealing 14 and a smoothing 15 vibrating bar, a cross-cutter 16 of the transverse joints with electrovibrators 17, driven by the tractor’s power station, are installed at the rear of the frame. At the end of the frame is a ladder 1 & for service personnel. In the upper middle part of the bunker, there is a feed funnel 19. When the vibroform (Fig. 1) is moved t through the wall 3, the sweep knives 5 and 6 of the bottom and side portions cut off the unevenness and the surface of the soil foundation, preparing it for the concrete laying. The soil is cut along the entire perimeter of the channel section, fed to the rotating augers 7 and, being held by the covers, is transported along the inclined surface of the front wall 4 of the bunker 2 to the berms. When moving, the vibroform rests on the profiled bottom of the channel with the shoe 9. At the same time, a concrete mix is fed from the concrete mixer into the hopper 2 using a funnel 19, which falls on the blade distributor 12 of the rear wall 10. The concrete mix moves along the bottom perimeter and accumulates at the forming slot of the vibroform. When the latter is moved along the channel, the concrete mixture is laid down by the shelves 11 successively along the slope height, which contributes to its better stability on the slopes. Using the vibrating bar 14, the mixture is compacted, and the smoothing bar flattens the surface of the lining. The cross joints are cut with a cutter. 16 The offered vibrating mold is specially designed for building small canals and permanent distributors for wide-ranging irrigation equipment with continuous unloading of the concrete mix from truck mixers, so Y has a small size, light weight and part of the traction amplifier is used for the final finishing work of the soil foundation. for draft

preparation channels for such channels may be

plow canal diggers are used.

The use of the invention will allow

in a single technological process, to refine the soil base and lay the concrete lining on small canals at relatively high speed.
