Abstract

The invention relates to the field of construction, in particular to methods of strengthening soil structures. The purpose of the invention is to increase the reliability of strengthening the surface of the soil structure against water and wind erosion. The method consists in that work on the object begins with partial loosening of the soil with simultaneous introduction of oil into the soil structure at the boundary between the body of the soil structure and the surface layer accepted for strengthening to a depth equal to the design thickness of the fortified layer. Then, water the surface soil construction with oil, give time to soak the soil with oil, ignite oil on the surface of the soil construction. After burning out from the oil of light fractions, the flame is extinguished. The surface layer of the soil is compacted. Re-pour the surface of the soil structure with oil. The exposure is allowed to cool the surface of the soil structure to ambient temperature. The oil ignites on the surface of the soil structure. After burning out the light fractions from the second layer of oil, the flame is extinguished. A soil structure is obtained with a fortified surface layer of soil consisting of lumps of soil, asphalt formation with thickness a at the site of the oil layer introduced into the soil massif, layer 7b, in place the first layer of oil deposited on the surface and layer 8 with a thickness bj in place of the second applied layer of oil.

Description

The invention relates to methods for strengthening soil structures and can be used for the erection of a roadbed of railways and highways, p-structures, platforms for drilling rigs, etc.

The aim of the invention is the superior reliability of strengthening the surface of the soil structure against water and wind erosion.

As the coulter 10 passes along line I-I, the soil is clipped and layer 3 is elevated to the height a. In this case, the soil of layer 3 is crushed into lump 4 with the formation of gaps between them. The oil pouring from the oil supply pipe 11 fills the voids and gaps and is deposited by the layer 3. Such introduction of oil is very expedient. It is introduced from the bottom up, as it pours out into the void with the soil loosening, first applied by 40 ore, equal to the excess of the surface of the soil 6 layer of oil.

The container of the oil tank is above the lower end of the tube 11. Due to this pressure, the oil fills the voids and rises into the gaps, forcing the air out of the voids and the gaps upwards. There are no air bubbles in the oil layer 5. Clod 4 is formed with cracks (not shown) in them, which are also filled with oil from bed 5.

The container of the oil tank is above the lower end of the tube 11. Due to this pressure, the oil fills the voids and rises into the gaps, forcing the air out of the voids and the gaps upwards. There are no air bubbles in the oil layer 5. Clod 4 is formed with cracks (not shown) in them, which are also filled with oil from bed 5.

After the operation of partial loosening of the soil with the introduction of oil into the soil structure 1 at the border of the melody 2 with the body 2 of the soil layer 6 of oil, thick of layer 7 of the spectrum of 55 weapons and methods to strengthen the heavy fractions, surface thickness bj layer 3 at depth, layer 8 of sintered fractions. equal to the design thickness, strengthened with the method of drying, made next layer 3, applied to the surface at once.

iroizrod partial soil loosening. By the term partial loosening is meant the loosening without flipping the cut layer of soil and mixing the particles and clods of soil in this case. Of the existing working bodies of construction and soil-cultivating machines for cultivating this operation, the cultivator-flat-cutter intended for tillage of the soil without plowing is best suited. At the same time, the soil-cultivating machine is supplied with a working organ

A torus consisting of a stand 9 and a coulter 10 with a wing valve is attached to the oil supply pipe 11. To the mounted equipment of the tractor should be added a tank with oil, with the cavity of which is connected the upper end of the oil pipe 11

With partial soil loosening, oil is introduced into the groundwater.

construction FIG. 1, line I-I denotes the boundary of the surface layer along which loosening (separation from the massif) of the surface layer 3 is performed. As the coulter 10 passes along line I-I, the soil is clipped and layer 3 is elevated to the height a. In this case, the soil of layer 3 is crushed into lump 4 with the formation of gaps between them. The oil pouring from the oil supply pipe 11 fills the voids and gaps and is deposited by the layer 3. Such introduction of oil is very expedient. It is introduced from the bottom up as it pours into the void from

The container of the oil tank is above the lower end of the tube 11. Due to this pressure, the oil fills the voids and rises into the gaps, forcing the air out of the voids and the gaps upwards. There are no air bubbles in the oil layer 5. Clod 4 is formed with cracks (not shown) in them, which are also filled with oil from bed 5.

b oil (Fig. J) thickness b. The oil layer 6 merges in the gaps between the lumps 4 with the oil layer 5. The time is given for the soil to be impregnated with oil layer 6. Since oil is a viscous liquid, it takes some time to fill pores and cracks in soil blocks 4. After oil is impregnated with the soil, the oil will ignite on the surface of the soil structure. From oil burn out light fractions. The heavy fractions melt, become fluidized. They flow into voids, cracks and pores between particles and clods of soil. After the light fractions burn out from the oil, the flame is extinguished. The molten mass of the oil components and the fractions of the fractions is sintered with heated soil particles and lumps 4, forming an almost asphalt layer 7

thick b, which is the largest slice of the oil layer, when burning oil, the burning of light fractions occurs in the gaps between lumps 4 to a considerable depth (FIG. 4),

Unheated surface layer

Soils with lumps 4 and asphalt formation 7 are compacted, for example, with rollers. In this case, the surface of the subsurface layer is leveled, lump 4 is deposited down, and, oil layer 5 is reduced to a (fig. 4). In layer 7, cracks are formed, through which water vapor and excess air, which has expanded as a result of heating, escape into the atmosphere. . A second layer of oil is applied to the still warm layer 7 and give time to cool the surface of the soil structure to ambient temperature. In the cracks, voids and pores of the surface layer, a pressure drop is formed due to the cooling of water and air vapor. Oil from the second layer actively penetrates into the surface layer of the soil, fills voids, cracks and pores. Ignite

second layer of oil. The burning of light fractions occurs. From the tension, a melt of the layer 7 and heavy fractions of the oil layer 5 occurs. The flame is extinguished. Layers 5, 7, and 8 are formed, binding particles, lumps and clod of soil. The asphalt formation layers a, b.,., Bj are less important than the oil layers from which asphalt is formed. The reinforced surface of the soil structure has the appearance shown in FIG. five,
