Description

The invention relates to means for accelerating the preparation of the base during the construction of winter roads, and in particular to means for accelerating the freezing process in depth to the necessary limits of previously frozen wetland surfaces to an insufficient depth.

There is a method for preparing bases for winters in wetlands (RU No. 2349702 C1, E01C 19/29, published March 20, 2009), according to which the warm-up is carried out on the principle of piercing the spurs of a frosty marsh surface with a pointed working surface under the influence of a vibration drive installed inside the drum with spurs.

The disadvantage of this method is the low efficiency of the warm-up process due to the fact that the sharp working surfaces of the spurs mainly work on the principle of piercing and very little provide breaking (warm-up) of the frosted monolithic surface. In addition, this method has low reliability, up to a complete cessation of the process of warming up a pre-frozen swamp surface with a depth of more than 8 cm.

The task to which the claimed technical solution is directed is to create conditions that ensure the achievement of a technical result, namely, increase the bearing capacity of the base by accelerating the freezing process inland to the required values of wetland surfaces under the base of the carriage, provided that they freeze more than 10 cm deep.

The specified technical result is achieved by the fact that in accordance with the claimed method of accelerating the freezing of the bases of winter winters, the wetland surface that is previously frozen to a depth of more than 10 cm, which is to be prepared for accelerated freezing to the required depth, includes preliminary cleaning, a base stain under the winter winder with squeezing air bubbles and two adjacent strips in which holes are drilled, a fence through drilled water holes with peat impurities from the swamp massif, the distribution This water is spread over the entire surface of the cleaned and washed base under the carriage.

The presence of new operations — drilling holes, taking water through pedestrian impurities from the swamp massif through drilled holes, distributing this water over the entire surface, cleaned and washed under the base of the winder — accelerates the heat exchange process by eight or more times and thereby reduces the freezing time in such same ratio.

The invention is illustrated by drawings, where figure 1 shows a diagram of drilled holes; figure 2 is a diagram of the injection and distribution of water on the surface of the base of the winding.

A depth of freezing of the bases of car winters of 10 cm is insufficient for the passage of vehicles, as a rule, of heavy vehicles. Therefore, it is necessary to provide deeper freezing of the base to increase the bearing capacity.

The method of accelerating the freezing of the bases of winter winters (Fig. 1 and Fig. 2) in the conditions of preliminary freezing of the marsh surface 1 with a depth of more than 10 cm includes the following main technological operations: cleaning the frozen surface of 2 bases under the winter winder and two adjacent right and left strips for operating units with a drill 3; the swamp of the marsh surface 1 under the winder with a pneumatic skating rink with squeezing out air bubbles; drilling holes 4 with a drill 3 on adjacent strips along an edge located to the base; the intake through the drilled holes 4 of the water by the pump 5 from the lower part 6 of the unfrozen swamp massif 7. The pump 5 for water intake must not touch the mineral surface of the bottom 8 of the swamp. Water on the surface 2 of the bases under the winder is distributed in the form of layers 9, for example, using a hose 10 and a trolley 11.

The workflow on the proposed method of accelerating the freezing of the bases of winters is as follows. To accelerate the process of freezing in depth to the required values of a previously frozen marsh surface 1 layer with a thickness of more than 10 cm after a certain time of their stay, as a rule, under snow at negative ambient temperatures, the marsh surface under the base of the winder and two adjacent strips are cleared of snow, for example , using a bulldozer with a sweeping brush. Next, the surface of the base 2 under the winder is blotted, for example, with a pneumatic skating rink with squeezing air bubbles. Then, holes 4 are drilled with a drill 3 (FIG. 1 and FIG. 2) of adjacent strips and then taken through the drilled holes 4 with a pump 5 from the bottom 6 of the unfrozen swamp massif 7. The pump 5 for water intake must not touch the mineral surface of the bottom 8 swamps. Water on the surface 2 (FIG. 1 and FIG. 2) of the bases under the winder is distributed in the form of layers 9 using a hose 10 and a trolley 11.

The application of the proposed method of accelerating the freezing of the bases of winter winters allows you to:

- significantly reduce the duration of the freezing process to the required depth;

- to increase the efficiency and reliability of the process of freezing previously frozen swamp surface with a layer more than 10 cm thick;

- reduce the duration of the process of preparation of the bases of winter winters to accelerate freezing.
