Description

  . ... - .The invention relates to the technology of production work ino11Krepleneniyu soil in construction, in particular, to the depletion and the carrying capacity of the underground layer of the soil11 track. A known method is to strengthen the soil layer by injecting paCTitbpir through vertically drilled wells (1. The disadvantages of this method; they can only be used) pumping the solution and defrosting it mainly around the bottom; This slows down the pace of work and does not both ensure the creation of equal strength 1 layer of soil reinforcement. The closest IK of the invention is the method of reinforcing the subbalanced | soil layer, which includes the formation of a Negro Mnala over a 1critical layer of soil and an introduction to the g, root through dao, 1Ka; Pouring mortar is injected by pouring it over the surface of the G-roll, which leads to a G-6 penetration of the soil and bore corollary, the reinforced soil layer has a different strength in width and length, B; pe3j S6 doesn’t ensure cross-layer strength. iyo bypass to increase the load on the track. The purpose of the invention is to increase the uniform strength of the soil layer by pasiHOMcpHoro distribution in the slurry solution. This is achieved by the fact that the method is Y5; | 5yyLyyTp15dbollatnogo soil layer of the railroad track including the formation of superstructure (by the ground layer of the haepechectual channel.and the introduction of the rpyiHT through the bottom of the channel The lastHef .6 is carried out by moving the high-pressure jets with intersecting trajectories; In the plan, after which the surface leveling and compaction of the saturated solution are carried out, rum. The technology for performing the proposed method for / includes is in the formation of continuously moving A reinforced layer of soil — a transverse channel) of channel 7, into the ground, is introduced into the soil by moving, in terms of, clumps under a pressure of 100-150 kgf / cm, whose trajectories intersect. As a result, the soil loosens with and paLBHOZHERZHP1ropity, vaVaR | Stv6roM, after which the soil is leveled and compacted. As a mortar is a solution Iopolzuyu carbamide resin brand M-2 and M-3,

 FIG. 1 shows the operating equipment for implementation. the proposed syosoba, incision; in fig. 2 - toyo rlMschenie under ballasts across the track; in fig. 3 - trajectories of jets moving in the slurry solution in the plan.

Strengthening the subbalanced soil layer is as follows.

In the p-adbalance layer / ground of the canvass 2 iron, Ors Z1nogo way, they attach a KNIFE 3, prikratslny to the back-stand: m 4 platforms on the course of the move (not shown). Then the reinforcing layer 5. A ground. Is limited.

on the top 1 and from the sides with shields 6 attached to the knife 3. By means of a separator .7, moving with the knife, through the nozzles 8 jets 9

High pressure, moving, in terms of intersecting trajectories 10, the cement mortar IB is reinforced. Under the influence of high-pressure jets, mixing of the soil with the holding solution e with the edge shields 6 of the reinforcing layer 5 occurs.

The freshboards of the shields 6 are leveled and compacted by the saturated gruat with the continuous movement of the knife 3.

The use of the proposed method of strengthening the layer in the subbalt base provides for the creation of a more uniform thickness and thickness of the soil layer, which will increase the effect of rail traffic with annual savings of about 40 thousand rubles. per 1000 km of railway track.

Invention Formula A method of strengthening the water ballast layer of the soil of the relaxation path, including the formation of a transverse channel above the reinforced layer of soil and the introduction of a trenching solution into the soil through the bottom of the channel, characterized in that 1C slit increasing the uniform strength of the soil layer to evenly distribute the mortar, introduction in the holding solution, it is carried out by moving the high-pressure jets with moving along the trajectories in the plan, after which the surface is leveled and compacted with a saturated soil solution.
