Abstract

FIELD: building, particularly for pavement forming.

SUBSTANCE: pavement includes tire-covers of different diameters arranged concentrically one inside another. Pavement is composed of separate sections connected one to another by interlocks formed, for instance, as steel cylinders. Each section comprises tire-covers laid one upon anther by their sides and grouped in stacks of equal heights. Tire-covers are connected one to another by fasteners and arranged in staggered rows. Tire-covers in each horizontal row are also connected one to another by fastening members. Attached to upper and lower tire-cover ends are discs. Tire-covers are filled with foamed polymeric material. Pavement also has skids located in place of maximum load applied by vehicle wheels and tracks to pavement. Attached to upper pavement surface are steel strips arranged coaxially to skids. Steel cylinders of interlocks are covered with discs having strips attached thereto.

EFFECT: improved resilience, possibility of pavement laying on soft grounds with positive floatability and increased load-bearing capacity, possibility of utilizing used difficult-to-recycle items, reduced cost and increased simplicity.

Description

The invention relates to the field of road construction, in particular, the structural design of pavement.

Known collapsible road surface, erected on soft soils, including elements located across the road with through holes through which cables are passed. The coating is equipped with flexible inflatable chambers, which are placed along it on the side facing the soil and are attached to the coating elements by means of flexible clamps, and each cable at the ends is equipped with tensioning and fixing devices (USSR author's certificate No. 612989. IPC E 01 C 5/22, 1975 )

Known collapsible coating for the repair of pipelines in the swamps, including a deck of transverse elements, pinched at the ends between the upper and lower longitudinal elements and combined along the length of the compression tightening elements. The coating is equipped with inflatable chambers located under the transverse elements in the zones of joints of the longitudinal elements (USSR author's certificate No. 1622484, IPC E 01 C 9/08, 1988).

Known road clothing containing tires of different diameters, with tires of a larger diameter located close to each other, and tires of a smaller diameter in a confined space formed by adjacent four larger tires and inside each tire of a larger diameter (USSR copyright certificate No. 777135, IPC E 01 Since 5/00, 1978) - the closest analogue.

Known collapsible coatings have a weak bearing capacity and weak strength characteristics when working in extreme climatic conditions and during the construction of oil pipelines using heavy tracked vehicles.

The objective of the present invention is to remedy these disadvantages, namely, the creation of an elastically deformable quick-assembled roadbed for soft soils with positive buoyancy and high bearing capacity. Other objectives of the invention are the use of used products, the processing of which is difficult and which pollute the environment, as well as the creation of a simple and inexpensive roadbed.

This problem is solved by the fact that in a collapsible roadbed containing car tires of various diameters, concentrically inscribed into each other, it consists of separate interconnected by means of lock joints made, for example, in the form of steel sleeves, sections, in each of which tires are mounted on each other with sidewalls in the feet of the same height and interconnected by tie elements, while the feet are installed in rows, and in adjacent rows the feet are staggered in each mountain The tire rails are fixed to each other in the horizontal row, the discs are fixed at the top and bottom of each tire stack, and the inside of the tire is filled with foamed polymeric material, in addition, the roadway is equipped with runners attached to it from below, located in the center of the pressure of the wheels and tracks of vehicles, and steel strips are placed coaxially with the runners on top of the sheet, while the sleeve of the locking joints are closed by disks on which the strips are fixed. Polyurethane foam or foamglass is used as a foamed polymeric material. The strips are coated on one or both sides, for example, from the tread parts of tires. Along the edges of the roadway there are curbs from tires. The runners are made of cut, for example, into three segments and partially rolled out used oil pipes. The space between the runners and the lower disks is filled with foamed polymeric material. Disks covering the feet of tires and sleeve lock joints made of rubberized steel.

In Fig.1 shows the roadway in plan, Fig.2 is a cross section of the roadway, Fig.3 is a section bB in Fig.2, Fig.4 is a lock connection of sections of the road in plan, Fig.5 is a cross section of the castle connection.

The roadbed consists of separate, interconnected sections, each of which contains tires 1 of various diameters, concentrically inscribed into each other and mounted on top of each other in the feet of the same height. The feet of tires 1 are installed in rows, and in adjacent rows the feet are staggered. In the foot of the tire 1 are connected at six points by the coupling elements 2, and in each horizontal row by the coupling elements 3. On top and bottom of each foot of the tire 1, rubberized steel wheels are fixed 4. On the upper disks 4 there are technological holes 5 for filling the inner space of the tire 1 under pressure foamed polymeric material 6 (polyurethane foam, foam glass, etc.). Thus, out of the plurality of tire covers, a web section is formed of predetermined overall dimensions. To increase the longitudinal stiffness and strength of the structure, it is equipped with runners 7 attached from the bottom along the canvas. Runners 7 are made of cut into three segments and partially rolled out used oil pipe. The center of the belt runners 7 is located at the center of the pressure of the wheels and tracks of the vehicles used. The space between the runners 7 and the lower disks 4 is filled with foamed polymer material 6 in order to avoid the ingress of water and dirt into this space. Above the edges of the canvas to ensure traffic safety are mounted in the manner described above curbs 8 from tires of small diameter. Also on top of the web coaxially with the runners 7 are two strips 9 of a steel sheet rubberized on both sides. Rubber sheets for strips 9 can be made from the tread parts of tires, fasten to strips 9 with glue and bolts, and are pressed against them with steel trims.

The roadway is assembled at the place of use from separate sections having lock joints at the ends 10. These joints are made in the form of steel sleeves 11, hermetically sealed from below with plugs 12. The sleeves 11 have holes for fastening the joined feet of the tires to each other with studs 13. After tightening the feet with studs 13, foam plugs are inserted into the sleeves 11, the sleeves 11 are closed by the disks 4, after which rubberized steel strips 14 are placed and fixed, which close the castle connection and connect strip 9 between them. The canvas does not require preparation of the foundation, which is important when building roads on a marshy surface 15, in the permafrost zone, in particular when laying oil and gas pipelines. The canvas can be installed on ice crossings across rivers.

Moisture that has fallen on the roadway drains into the gaps between the feet set in a checkerboard pattern. When moving along a transport canvas in winter, ice from the canvas is chipped, crushed and easily removed due to elastic deformations with restoration of the upper side; it is also possible that there is no rubber on their surfaces, in which case they have fins or are made with steel notch.
