(57) The invention relates to the field of hydraulic engineering. The purpose of the invention is to increase the reliability of the dam, simplify the work on its construction and reduce labor costs. The dam includes a diaphragm installed in the dam body, formed of recycled single-type tire covers filled with low-permeable soil placed in rows along the height, and april of impermeable film on the side of the diametrical plane two straight, parallel to the longitudinal line of the notch diaphragm, the width of which is equal to half the width of the width of the width of the width of the width of the width of the width of the width . The width of the aprons should be less than the difference between the outer and inner diameters of the toroidal tire covers. Aprons are reinforced in the notches of adjacent vertical rows of tire covers. 4 il.

FIELD OF THE INVENTION The invention relates to hydraulic construction, in particular to the construction of impervious diaphragms of dams.

The purpose of the invention is to increase the reliability of the dam, simplify the work on its construction and reduce labor costs.

Figure 1 shows the proposed dam with a diaphragm, the section; figure 2 - diaphragm, cross section; on fig.Z - the same, front view; figure 4 - tire with notches.

The diaphragm 1 of the dam 2 is formed from recycled tire covers 3 placed in rows along the entire height, filled with low-permeable soil 4. The recycled tire covers have cuts 5 into which the aprons 6 are inserted and reinforced.

WITH

The diaphragm 1 of the dam 2 of the proposed construction is erected as follows. Old type tires 3 are delivered to the site. Aprons 6 are made of a flexible impermeable material, such as polyethylene. The height of each apron 6 must be equal to the height of the diaphragm 1, and the width of each apron 6 must be less than the difference between the outer and inner diameters of recycled tires 3. On each tire 3 along its sides, through 180 °, with the help of a saw, two straight parallel longitudinal The lines of the diaphragm 1 notch 5, whose width is equal to half the width of the apron 6. The first horizontal row of tire covers 3 is laid so that the adjacent notches 5 of the adjacent tire covers 3 of the horizontal row of pattern 00

A single line was ejected, and aprons 6 were inserted into these notches 5 at the same time. Having thus laid several horizontal rows of tires, their internal cavities were filled with weakly permeable soil 4. Then they begin to pour the upper and lower prisms of the dam 2 up to the level of the diaphragm 1. several horizontal rows of tire covers 3 with installation of aprons b in notches 5, with filling of tire cavities with poorly permeable soil 4, i.e. All the technologies are repeated, as with the laying of the lower arm of diaphragm 1 and dam 2, until the completion of the construction of diaphragm 1 and plastic 2.

Example, Based on the design task, you need to build an earth dam with a height of 8 m and a length of 40 m with a membrane-proof diaphragm with a height of 7.2. For the device of diaphragm 1, single-type recycled tires 3 are selected, for example, model B-107, with an outer diameter of 57 cm, an inner diameter of 32 cm and a width of 15 cm. To form a single horizontal row of a diaphragm, 73 tire covers are needed, and one vertical row 48 tire covers. In total, 3504 tires are needed for the device diaphragm.

 Aprons 6 are made of polyethylene film 7.2 m long and 20 cm wide. In total, 72 apron need to be made,

On each tire through 180 ° on the sides, using a saw, make two straight cuts 5, the width of which should be

equal to half the width of the apron, i.e. in this case 10 cm.

Into the inner cavities of the tire covers, after installing the horizontal tusk and securing the aprons 6 in the notches 5, low-permeable soil, such as clay, which is rammed in layers, is fed from above. After the laying down of each tier of diaphragm 1 of the four horizontal rows of tire covers, the corresponding tiers of the upper and lower prisms of the dam 2 are laid.

Claims (1)

Claims of the invention of the dam, including the body of the dam a diaphragm formed from. placed in rows along the height of the reclaimed uniform toroidal elements in the form of tire covers filled with low-permeable soil, and aprons from an impermeable film installed in the joints between the vertical rows of reclaimed tire covers, characterized in that, in order to increase the reliability of the dam, simplify the construction of the dam and reduce labor costs, the recycled tire covers are made on the sides in the diametral plane with straight notches placed parallel to the longitudinal line of the diaphragm, In this, the width of each notch is equal to half the width of the apron, and the width of the aprons is smaller than the difference between the external and internal diameters of the toroidal elements, and the aprons are reinforced in the notches adjacent vertical rows of tire covers. figure 1 fig.Z 2 4
