The invention relates to the construction and can be used mainly in the construction of the earth roadway on weak soils.

The purpose of the invention is to increase the carrying capacity.

Figure 1 shows the profile of the roadbed; 2 and 3 are the same examples of execution.

The roadbed includes slots 2, made on a weak base 1, located along both sides of mineral embankment 3, and layer 4. Interlayer 4 of non-woven synthetic material (for example, dornit) is located on the ground of base 1 under embankment 3, and its ends 5 overlap the top of the slot 2. On the inner side of each of the slots 2, under the layer 4, there are support rollers 6.

Rollers 6 can be made in the form of flexible pipes 7 from non-woven synthetic material, and their internal cavity is filled with mineral primer 8.

The support rollers 6 can be cut to the bottom with cut used automobile tires 9, which are in contact with the edges of the protectors

The roadbed is erected in the following way.

At the base 1, parallel slots 2 are torn off, and the soil to be retrieved is laid between them. Support rollers 6 are formed from the extracted soil, which are made as close as possible to the neighboring edges of the slits 2. Then, a layer 4 of nonwoven synthetic material is placed on top of the rollers 6, and its

the ends 5 overlap the slots 2 with a margin. Then over the layer 4 are parallel (both slots at once) filling of the slots 2 imported prigruznym soil. Layer 4 is tightened and loaded with soil in this case, and its ends 5 are fastened. In the future, the layer 4 are filling the embankment 3.

When building the road of FIG. The 2 support rollers 6 can be made by hydraulically washing the soil 8 directly into the flexible pipes 7 of non-woven synthetic material that are laid at the edge of the slots 2.

When arranging the road according to FIG. 3, used auto tires 9 are placed on each of the support rollers 6, which have a cut downwards, and the edges of the protectors are joined to each other.

Claims (3)

1. A ground roadway, including a base, a mound of mineral soil, slots along both sides of the embankment, and under it a layer of non-woven synthetic material, the ends of which overlap the slots, characterized in that an interlayer between the slits is provided with support rollers. 2. Cloth according to claim 1. characterized in that each supporting roller is made in the form of a flexible pipe from non-woven synthetic material, the internal cavity of which is filled with mineral primer. 3. Cloth according to claim 1, characterized in that the top of each support roller is stacked against each other by the edges of the tread and the cut down used auto tires. 2 / Editor A.
