METHOD OF EARTHEN CEMENT CONCRETE DIAPHRAGM PLATE CONTROL IN GROUND DAM Russian patent published in 2017 - IPC E02B7/06 E02B3/16 

FIELD: construction.

SUBSTANCE: method of earthen cement concrete diaphragm 3 plate control in a ground dam 2 includes the fiber optic temperature sensor 5 laying along the entire area of the earthen cement concrete diaphragm 3 from the side of the tail pond 4 and its connection to the reading fiber optic transceiver determining the fault location and the leakage amount through the earthen cement-concrete diaphragm 3. To do this, waterproof shelves 1 of dawk are poured in steps of 1.0-3.0 m and slope i towards the lower dam 4 in the process of erecting a ground dam 2 along its height in the zone of the subsequent creation of a earthen cement concrete diaphragm 3 for directing the flow of water towards the location of a fiber optic temperature sensor 5 layed along the edges of the waterproof shelves 1. The width of the waterproof shelf 1 is taken to be at least 2.5 to 3 times of the width of the earthen cement concrete diaphragm 3 to prevent damage to the fiber optic temperature sensor 5 during subsequent drilling operations to create a earthen cement concrete diaphragm 3.

EFFECT: location of damages in the earthen cement concrete diaphragm of the ground dam correct to 1m, quantitative assessment of the water filtration volume through damages, reduction in the time and costs of their detection and elimination.
