Description

The utility model relates to road construction, in particular, to the construction of coatings providing increased cross-country ability of automobile and tracked vehicles, increased adhesion of tires or tracks, protection of concrete, asphalt or other other road surface or parking places of automobile and tracked vehicles.

Known road clothing, including a coating, a drainage layer located between the coating and the base, and a cushioning layer made of rubber-cord tires, the tires are made with through holes through which T-shaped studs are passed (see Auth. Certificate. USSR 672273 by cl E01C 5/00 from 05.07.75).

Pavement is also known in which rubber-cord tires have a different diameter, with larger tires lying close to each other, and smaller tires placed in a confined space formed by adjacent four larger tires and inside each larger tire (see Auth. USSR 777135 according to class E01C 5/00 from 11/7/80).

The disadvantage of such coatings is the insufficient density of the shock absorbing element.

Known pavement in the form of elastic elements flush with utilized tires laid flush with the surface of the roadway, each element being straightened and having radial cuts on the sides (see Aut. Sv. USSR 1409711 according to class E01C 5/18 of 07.15.88) .

The disadvantage of this coating is the constant bending of the road surface during a collision with vehicles, the need to ensure air pumping along the element, since the absence of such pumping will lead to the formation of dents and indentations on the road surface.

Also known is the road surface, consisting of elements pulled together by ropes, cut from recycled tires, placed at the bottom, each element being made of half of a recycled tire with a cut plane passing in the middle of the tread portion and anchored to the base (see ed. USSR 1647068 according to class E01C 5/00, 5/18).

The disadvantage of this coating is the rather high complexity of its manufacture, the need to perform all work on the construction of the pavement directly on the roads.

Known pavement made in the form of elastic elements stretched together, which are made of rubber-cord products, in particular cut from recycled tires, conveyor belts and other rubber-cord products (Utility Model Patent RU 9454 U1, IPC E01C 5/00, 06/24/1998 ) Elastic elements in the form of rectangles or parallelograms are mounted close to each other perpendicular to the plane of the road. The elements tightening them are passed through the holes made in advance and their ends are connected. Tightening elements are placed when laying the pavement mainly along the road.

The disadvantage of this coating is the location of the elastic elements in the form of rectangles or parallelograms, perpendicular to the road plane, which leads to the high complexity of its manufacture from the relatively small thickness of the road surface of elements that perceive the load that does not correspond to the load, for the perception of which they are designed in accordance with their strength characteristics.

A pavement is known, including carrier and connecting elements fastened together, cut from recycled tires, while the connecting elements are formed from tread parts deployed in strips, the bearing elements are made in the form of tread parts deployed in a strip, longitudinally arranged in a row with the tread up, and binders the elements are transversely located under the bearing elements of the coating and are attached to them at the ends of adjacent strips (SU 1691448, E01C 5/18, 20.12.88). Bearing and binding elements are cut from recycled tractor tires.

The disadvantages of this coating is the complexity of the manufacture and installation of the pavement due to the need for orientation and fastening at the ends or with some step of the adjacent supporting elements by connecting elements by means of additional bolt connections (Col. 4, lines 19-20). The lack of fastening of the lanes directly between themselves, as well as the location of the lanes at a certain distance (Figs. 2 and 3 of the patent) creates the possibility of discontinuity of the coating, and does not exclude the ingress of soil, dirt (Col. 4 lines 23-25) on the road surface and reduces it strength and patency for automotive and tracked vehicles due to its slipping. The vertical arrangement of bolted joints causes increased wear of the coating in places of contact with fasteners, especially on hard and rocky surfaces and the corresponding loss of strength characteristics and wear resistance of the coating, especially for tracked vehicles.

The proposed utility model solves the problem of simplifying the manufacture of temporary pavement, increasing the strength characteristics of the road surface and parking lots of automobile and tracked vehicles, increasing the permeability of automobile and tracked vehicles

The solution to this problem will provide the following technical result:

speed up the manufacture of coatings;

increase the wear resistance of the coating;

increase cross-country ability for automotive and tracked vehicles.

The technical result is achieved in a temporary road surface, including elastic elements made of recycled rubber cord tires made in the form of strips, each of which is a straightened tread part of the rubber cord tire after its cross section, and the strips are installed close to each other, so that the temporary the pavement is made by fastening these strips along their long sides by means of an integral connection.

In addition, at least in the extreme lanes on the side of laying on the road, holes are made through which flexible rods with locking elements at the ends are passed.

In addition, the one-piece bonding of the strip fastening is accomplished by riveting, stitching, gluing or other similar one-piece bonding.

The manufacture of elastic elements and the assembly of pavement is carried out at specialized enterprises. Directly on the surface, the pavement is laid out on an existing foundation.

The proposed utility model is illustrated by drawings.

In FIG. 1 - temporary pavement.

In FIG. 2 is a diagram for preparing a profile of a recycled rubber cord tire.

In FIG. 3 is a cross-sectional diagram of a profile of a recycled rubber cord tire to obtain a strip.

In FIG. 4 - arrangement of flexible traction in the holes.

Temporary pavement includes elastic elements made of recycled rubber cord tires mounted close to each other. The elastic elements are made in the form of strips 1, each of which is a straightened tread part of the rubber cord tire after its cross section, and the temporary pavement 2 itself is formed by fastening the strips 1 along their long lateral sides 3. Holes are made in the extreme strips from the side of the road 4, through which flexible rods 5 with fixing elements at the ends are passed 6. The fastening of the strips can be carried out with rivets, stitching, gluing or other one-piece connection (not shown).

This combination of features provides the rapid production of temporary pavement with a small number of preparatory operations. The entire load on the road surface is perceived by the tread portion of rubber-cord tires intended for this purpose, the location of the strips close to each other and the fastening of these strips along their long lateral sides by means of an integral connection, provides an increase in the strength characteristics of the coating and its wear resistance.

Reduces the likelihood of soil and dirt getting on the surface of the road surface and, accordingly, skidding of vehicles.

Mobility and the ability to assemble the coating from an arbitrary number of strips allows to increase the permeability of the coating for automotive and tracked vehicles on any hard surfaces.

Temporary road surface (VDP) is made as follows:

1. From a whole car tire are cut:

a) the side parts on both sides so as not to affect the tire breaker 7 (see Fig. 2, a).

b) the side parts with the tire shoulder in such a way as not to affect the tire breaker 7 (see Fig. 2b).

2. The rest of the tire is a cylinder. The outer part of the cylinder is the tread part of the tire.

3. The cylinder is cut in one cross section as indicated in FIG. 3. As a result of the cut, a strip is obtained with a length equal to the length of the outer circumference of the tire and a width approximately equal to the width of the tire profile.

4. The resulting strips are fastened to each other along the long side in any way: rivets, stitching, gluing, etc.

5. Bonding together several bands according to paragraph 4, we obtain a coating, the upper part of which is several rows of stripes of tire treads (see Fig. 1).

6. At the ends of the VDP, a steel cable is stretched from one edge to another - flexible rod 5 (see Fig. 4), each end of which is bent to form a ring - a fixing element at the end 6. The ring is fixed with a carbine or in another way. These rings allow you to:

- fix the VDP by means of (staples, nails, etc.) driven into the ground or other surface on which the VDP is laid;

- connect the VDP with each other, pulling together their rings in any way;

- move the VDP, clinging to the rings;

- fix the VDP in the back when transported by a vehicle.

7. Since, when cutting the cylinder according to paragraph 2, small (up to 1 mm) ends of the cut cord and breaker may appear outward at the slices, the ends of the TSS are closed by:

- trimming the ends of the cord and breaker;

- closing the end of the VDP with glue (sealant, rubber, etc.).

As flexible rods use a cable, wire.

The collected pavement can be rolled up or stored in flight, which is transported to a place where temporary pavement is arranged for the road or the parking place of automobile and tracked vehicles.

The road surface can be made both to the full width of the road or the parking place of the equipment, and to narrower sections - ruts.

The pavement laid on the base is secured with anchors if necessary.

If ice has formed on the road, then when hitting a vehicle cover, it cleans itself, as elastic elements due to the natural elasticity of the rubber are compressed during the collision of the transport and acquire their original shape after passing the transport. Due to this movement of elements, the ice breaks.

This road surface ensures a smooth transport by compensating for shock loads caused by temperature joints on bridges and eliminates the formation of “waves” (bumps) on ascents and descents by eliminating the fluidity of the pavement.

The proposed utility model achieves acceleration of the manufacture of the coating and increases the wear resistance of the coating, as well as increases the permeability for automotive and tracked vehicles.
