Description

(54) DEVICE FOR CONTAINING SLOPES

one

The invention relates to hydraulic engineering and is intended for concreting slopes of hydraulic structures.

A device for distributing bulk materials over the surface in various building earth structures 1 is known.

The disadvantage of this device is that it does not provide a rectangular cut-off area.

Also known is a device for concreting slopes, comprising a carriage with a blade, cooperating with a guide arm, and a vibration mechanism 2.

The disadvantage of this device is that it can only place concrete in a narrow area, while in the lower part of the slope the edge of the concrete surface must be leveled manually.

The aim of the invention is to increase productivity by increasing the width of the grip.

This goal is achieved due to the fact that the blade is provided with a set of plates that are connected in the upper part by a transverse beam, have a ski and are pivotally attached to the blade with the possibility of rotation in a vertical plane, with the plates in plan lying at an angle to the blade above its lower edge.

FIG. 1 given the device, front view; in fig. 2 - the same, top view (the dotted line shows the outline of the concrete before laying); in fig. 3 - the same, side view.

The device for concreting slopes includes a carriage 1 with a blade 2, Q interacting with a guide arm 3, and a vibration mechanism 4. Before the blade 2 there is a set of plates 5 connected in the upper part by a transverse beam 6 and having an additional support Skis 7. Plates 5 are attached to

15 to the blade 2 by means of the hinges 8 with the possibility of rotation in the vertical plane and in the plan are located at an angle to the blade 2 above its lower edge 9, and the blade 2 has lower stops 10 on which the plates 5 are supported. The blade has

20 also have support rollers 11, which interact with reinforced concrete butt elements 12. To be able to control the thickness of the concrete layer being laid, the rollers 11 are provided with eccentric shafts 13.

The device for concreting slopes works as follows.

The docking elements 12 are laid along the side of the slope, between which a specific portion of concrete is poured out of the dump trucks directly (Fig. 2). The base machine (not shown) places the blade 2 on the docking elements 12. As the blade 2 moves along the side slope, the ski 7 hits the concrete, limiting the portion of concrete that is distributed along the blade line by the plates 5. After the plates 5 are lowered to the stops 10, the vibro-mechanism 4 is turned on and the carriage 1 moves the blade 2 to the bottom of the slope, and if necessary it puts the concrete in the bottom of the channel. At the same time, the concrete fills all the space between the joining elements and has an even edge in the lower part of the slope without the use of manual labor.

The device allows you to increase the width of the capture, reduce manual labor during installation

concrete and thereby increase productivity.
