METHOD OF LOCATION DETERMINATION OF DAMAGES AND THEIR CONTROL IN THE DAILY CONTROL POOL BOTTOM Russian patent published in 2018 - IPC E02B7/00 E02B9/00 E02D1/08 

FIELD: defectoscopy.

SUBSTANCE: invention relates to methods of reinforced concrete hydraulic reservoirs integrity monitoring using fiber optic test equipment and is designed to determine the location of damage in the daily control pools bottom and control leaks through them. Method of determining the location of the damage and monitoring it in the daily control pool bottom includes laying the fiber-optic sensor 6 over the entire area of the daily control pool in steps of 3–5 m, filling of a coarse-grained material layer under the daily control pool bottom 5, arrangement of the underground drainage gallery 10 adjoining from the outside to the daily control pool, transverse slant i_tra of the base 1 is made from the daily control pool axis to its edges, then a layer of coarse material, for example, crushed stone 2, is covered with a geo-synthetic filtering material 3, for example, dornite, to exclude suffusion / removal of sand 4 by the water flow, and an additional layer of sand 4 is filled onto it to form a spreading dome, which is obtained by leaks through the daily control pool bottom 5, connecting the fiber optic sensor 6 to the reading transceiver, which determines the damage location and the amount of leakages. Longitudinal slant i_long of the base 1 can be performed along the daily control pool axis in amount of 0.010–0.035. Transverse ribs, for example, reinforced concrete beads, can be installed over the whole area of the base 1 in increments of 3–5 m to create regular leakages local control zones. Fiber-optic sensor 6 can be laid from the reinforced concrete beads upper side continuously in all leakages local control zones.

EFFECT: technical result consists in determining of the damage points in the daily control pools bottom, quantitative assessment of the leakage through the damages, a reduction in the timing and costs of their detection and elimination, and an increase in the lifetime of the pools.
