Description

The invention relates to the field of construction using reinforcing geosynthetic materials, and in particular to road machines designed to strengthen soils and pavement.

A stacker is known for laying a volumetric geogrid (RF Patent 2527392, class E01B 29/05, publ. 08/27/2014), which includes a device for stretching the geogrid with working bodies intended for insertion into pockets on the left and right sides of the geogrid section, a containment device volumetric geogrid in the form of a drum or rack, as well as a roll of geotextile. The geogrid is installed on top of the geotextile unwound from the roll.

However, the disadvantage of this design is the inability to change the tension of the laid geotextile web, which can lead to the formation of wrinkles on it.

Closest to the claimed invention is a machine for laying geosynthetic materials in the roadway (RF Patent 2594491, class E01C 21/00, publ. 08/20/2016), which includes a folding crane, devices for holding rolls of geotextiles, a device for stretching a three-dimensional geogrid , a device for holding a stretched volumetric geogrid on the ground, a platform for placing packages of a volumetric geogrid on it, as well as a device for pulling a string of a volumetric geogrid from the package.

This design has the following disadvantages:

- the machine is intended only for installation and backfilling of cells of a volumetric geogrid;

- it is required to allocate an area for storing a supply of filling mixture for the bunker, and loading the mixture into the bunker is carried out using additional equipment, which significantly increases the cost of using the machine.

The technical problem to be solved by the claimed invention is to improve the quality and reduce the cost of laying geosynthetic materials in the road structure.

The problem is solved by the fact that the device for mechanized laying of geosynthetic materials in the road structure, including a platform on which a hopper is installed with discharge hatches located in the center and along the edges, according to the invention, contains drives, right and left augers with the same direction of rotation, having the ability to reversing the direction of rotation, an electric generator mounted on a platform, a body of a tensioner mounted on the outer side of the hopper with the ability to move relative to the wall of the hopper, sliders located in the side holes of the body of the tensioner with the ability to move along the guide ledges, an axis with a roll of geosynthetic material mounted on sliders by means of bearings, springs, which are a flexible connection between the sliders and the body of the tensioner, the lower drawbar with the possibility of locking, connected to the platform mounted on the rear axle with fixed wheels and the front axles with swivel wheels, upper drawbar, rigidly fixed on the outer side of the bunker.

The essence of the invention is illustrated by the drawings shown in Fig. 1, fig. 2, fig. 3, fig. 4. In FIG. 1 shows a device for mechanized placement of geosynthetic materials in a road structure (side view). In FIG. 2 shows a device for mechanized placement of geosynthetic materials in the road structure (top view). In FIG. 3 shows the tensioner. In FIG. 4 shows the flow chart for the production of geosynthetic materials in the road structure.

A device for mechanized laying of geosynthetic materials into the road structure consists of a hopper 1, drives 2, a right auger 3, a left auger 4, an electric generator 5 installed on a platform 6. The direction of rotation of the right 3 and left 4 augers is the same. On the outer side of the hopper 1 there is a body of the tension device 7, in the side holes of which sliders 8 are located with the possibility of moving along the guide ledges 9. The axle 10 with a roll of geosynthetic material 11 is mounted on sliders 8 by means of bearings 12. the tensioner 7 has the ability to move relative to the wall of the hopper 1. The springs 13 are a flexible connection of the sliders 8 with the body of the tensioner 7. In the center and along the edges of the hopper 1 there are unloading hatches 14. The lower drawbar 15 is connected to the platform 6 mounted on the rear axle 16 with fixed wheels 17 and front axle 18 with swivel wheels 19. The upper drawbar 20 is rigidly fixed on the outer side of the hopper 1.

A device for mechanized laying of geosynthetic materials in the road structure works as follows.

Installing the roll of geosynthetic material 11 on the axis 10 is done manually. Fixing the free end of the roll of geosynthetic material 11 on the subgrade is carried out using temporary anchors. The connection of the device for mechanized laying of geosynthetic materials into the road structure with the dump truck 21 is carried out by means of the upper drawbar 20. Loading a portion of the filling mixture into the hopper 1 is made from the body of the dump truck 21. Blocking the lower drawbar 15 ensures that the direction of movement of the swivel wheels 19 of the front axle 18 is fixed. devices for mechanized laying of geosynthetic materials in the road structure simultaneous rotation of the right 3 and left 4 screws leads to the supply of the filling mixture into the unloading hatches 14. The required volume of the filling mixture is regulated by changing the speed of rotation of the screws 3, 4. The possibility of laying adjacent rolls of geosynthetic material with an overlap is provided by unloading the filling mixture through the central and one of the side unloading hatches 14. The choice of the side unloading hatch for unloading the filling mixture is carried out by simultaneously reversing the direction of rotation of the auger kov 3, 4. In case of insufficient tension of the laid geosynthetic material, the movement of the slider 8 due to the spring 13 leads to the contact of the roll of geosynthetic material 11 with the front wheels 19, which results in an additional moment of resistance to the rotation of the roll. The possibility of relocating the device for mechanized laying of geosynthetic materials into the road structure is provided by attaching the lower drawbar 15 to the vehicle.

Thus, this invention makes it possible to improve the quality of laying geosynthetic materials in the road structure due to the presence of a tensioning device that excludes the formation of wrinkles on the laid material sheet, as well as to reduce the cost of work due to the layout of the device nodes, which makes it possible to use the dump truck body for storing the backfill mixture, as well as for loading a portion of the mixture into the bunker. The proposed technical solution can be used for laying various types of geosynthetic materials, for example, geotextiles, geogrid, geomat.
