The invention relates to hydraulic construction and can be used to seal the joints and gaps between ground-based prefabricated elements and structures in order to prevent filtration of water or other liquids through the joints of blocks, reservoirs and other containers during the construction of hydraulic structures.

The purpose of the invention is to reduce the labor intensity of construction, increase reliability and durability by using the hydrostatic pressure of the fluid to seal the joint

Figure 1 shows a filtering device, a general view; figure 2 - section aa in figure 1; on fig.Z - section BB in figure 1; Fig. 4 is a diagram of the distribution of hydrostatic pressure along the contour of the impervious device in the absence of an apron; figure 5 - the same, in the presence of an apron.

The counterhairing device includes a waterproof film 1 covering the gap 2 between the elements 3 and 4 of the mating surfaces, a seal retainer, made in the form of rough tracks 5–8, installed in pairs, in each of which they come into contact with each other by rough surfaces, This one of the tracks 5 and 7 is fixed on the elements 3 and 4 of hydrotechnical construction along the gap 2, and the other tracks 6 and 8 are fixed on the waterproof film 1, the latter being installed in the gap 2 with slack 9, na219711

outwardly directed hydraulic structures.

The waterproof film 1 can be made flush with rough paths (FIG. 4) or with an apron 10 (FIG. 3). The presence of the apron 10 ensures the pressing of the anti-filtration device to the building elements with greater force. Rough tracks 5 and 7 can be attached to elements 3 and 4 of a hydraulic structure by means of anchors 11 embedded in the material of the structure under factory conditions.

Rough tracks 5 and 7 can be attached to elements 3 and 4 of the structure at a distance B from gap 2, which is, in the optimal case, 2-3 times the value of gap 2 between elements 3 and 4 of the joined surfaces.

The displacement of the rough paths relative to the gap 2 ensures that the impervious device is pressed against the building elements with greater force.

In some structures, such an offset is not represented:. possible, and then rough do-HORRI are attached to the elements of the structure flush with them from the side of the gap (not shown).

The seal lock is performed as follows.

Rough tracks 5 and 7 are factory-pierced with anchors 11, and they are inserted into the unconsolidated concrete of elements 3 and 4 of the hydraulic structure along the future, In the case where elements 3 and

3

4 are made of metal, rough tracks 5 and 7 can be attached to them with glue,

The rough tracks 6 and 8 are also glued to the waterproof film 1 at the factory.

Mount the proposed anti-filtration device as follows.

Elements 3 and 4 of the hydraulic structure are installed in the design position. Waterproof film 1, collected in a roll, impose, closing the gap 2, on the elements 3 and 4 of the structure.

Then the reel is unwound, thus closing the gap 2 between the joined elements 3 and 4. At the same time, the rough tracks 5 and 7 interlock with the rough tracks 6 and 8 and thereby fix the position of the waterproof film 1 relative to the elements 3 and 4 of the structure. In this case, the film 1 is waterproof in order to avoid its stress during installation and the IB process is located in the gap 2 with a sag 9.

Then the hydraulic structure is filled with liquid, the filtration of which through the joints should be prevented. Since the hydrostatic pressure of the fluid is one-sided, it presses the waterproof film 1 against the plane of the joined

elements 3 and 4, thereby preventing filthism.

Figure 4 shows the scheme of operation of an anti-filtration device in the absence of an apron, i.e. in the case when rough paths are made flush with waterproof material 1.

Figure 5 presents a diagram of the work | bots of the filtration device in the presence of the apron 10.

In the first case, the hydrostatic pressure acts on the filtering device from two sides. On the one hand, the hydrostatic pressure of the fluid from inside the reservoir (hydraulic structure), and on the other hand, the hydrodynamic pressure under the seal during fluid leakage (Fig. 4).

However, the leakage of fluid through the seal due to rough tracks is difficult and inevitable pressure loss from the outside. Due to the fact that the hydrostatic pressure from the outside is less than that from the internal, the resulting hydrostatic pressure will always press the waterproof material 1 to the interface plane and the filtration will automatically be set and wounded. The presence of the apron 10 ensures the pressing of the waterproof material to the surface of the abutting elements 3 and 4 with greater force (figure 5).,
