RU53682U1 - DEVICE FOR DISTRIBUTING LIQUID BINDER TO SOIL - Google Patents

Abstract

The utility model relates to road construction and can be used for the device of protective layers on the basis of soil on the roads of lower categories.

The purpose of the utility model is to improve the quality of soil pavement bases by preventing the start of soil treated with a liquid binder on the undercarriage of the sealing mechanisms, increasing the depth of impregnation, and reducing the loss of binder due to its evaporation.

The essence of the utility model lies in the fact that the device for distributing a liquid binder into the soil, including a distributor with nozzles, further comprises a knife located obliquely in front of the binder distributor, a tray above the distributor for moving soil, side sheets, while in the space formed in the form of a box between the surface of the cut with a soil knife, a tray, side sheets and soil falling from the tray, hot air or exhaust gases are pumped to intensify the soil impregnation process

Description

Useful, the model relates to road construction and can be used for the device of protective layers on the basis of soil on the roads of lower categories.

Known devices for the distribution of binders or similar materials during construction and pavements, which are a distributor for the expiration of a binder from a system of holes, nozzles or a continuous gap and a system for feeding and storing a binder (see France No. 2566441, Czechoslovakia No. 241370, Russia No. 2075569 92016330).

The closest technical solution is a binder dispenser consisting of a distribution pipe with nozzles, the design of SoyuzDorNII, the scheme of which is given in the “Methodological recommendations for the installation of thin protective layers on concrete airfield coatings”. SoyuzDorNII. M., 1982, p. 35). This dispenser can be used to impregnate the surface of loose soil to create protective layers for the construction of the bases of road pavements from soil.

However, in this case, during the distribution of the binder, it is possible for the soil to stick to vehicles during rolling and partial evaporation of the binder from the treated surface.

The objective of the utility model is to improve the quality of the pavement foundations from soils by preventing the sticking of the soil treated with a liquid binder on the undercarriage of the sealing mechanisms, increasing the depth of impregnation, and reducing the losses of the binder due to its evaporation.

The essence of the utility model lies in the fact that the device for distributing a liquid binder into the soil, including a distributor with nozzles, further comprises a knife located obliquely in front of the binder distributor, a tray above the distributor for moving soil, side sheets, while in the space formed in the form of a box between the surface of the cut a knife of the soil, a tray, side sheets and soil falling from the tray, hot air or exhaust gases are pumped to intensify the process of soil impregnation.

The essence of the utility model is illustrated in the drawing, where in Fig.1 is a device in longitudinal section, Fig.2 is a view of AA.

The device comprises a knife 1, a tray 2, rigidly connected to the side sheets 3, to which a distribution pipe 4 with nozzles 5 is attached under the tray 2. The side sheets 3 have nozzles 6 through which hot air can be pumped into the space between the tray and the surface of the cut soil, or tractor engine exhaust. In front of the knife 1, loosening rods 7 are placed over its entire width. The entire device with struts 8 is rigidly connected to the beams 9, which are used to connect the tractor with the mechanism for raising and lowering the device.

The device operates as follows.

When the device is moved by the tractor, it is deepened to the required depth, the loosening rods 7 loosen the soil in front of the knife 1 to a depth below the knife 1. The soil cut by the knife 1 moves along the tray 2 and falls behind it. When the nozzles 5 are working, both the surface of the cut loosened soil by loosening rods 7 and the falling pear from the tray 2 are processed. Into the space under the tray 2 between the side sheets 3, knife 1, the surface of the cut soil and soil falling from the back

hot air (or exhaust gases from the engine) is pumped through the pipe 6, which not only improves the processing of the soil with a binder, heating it, but also intensifies the soil impregnation with a binder due to pressure impregnation. During subsequent rolling under pressure, the treatment of impregnation of the cut soil with a binder takes place. The depth of cut of the soil is regulated by moving the device in the vertical direction with fixation.

The proposed device can be used as attachment to soil mixing machines of the type DS152, installing it directly behind the mill, while the depth of impregnation will increase, and the loss of binder will decrease. Also, this device can be used in the device of road surfaces of the lower categories of capillary-breaking interlayers.
