METHOD OF DETERMINATION OF PARAMETERS OF UNDERGROUND SPACE Russian patent published in 1994 - IPC

FIELD: construction industry. SUBSTANCE: fluid is used as working medium. To determine presence of underground waters in space means for monitoring presence of underground waters is inserted into it. Its sensitive element is positioned in lowest point of space. Discharge of pumped out underground waters or of pumped-feed fluid, time of change of their level to fixed level equal to spacing of layer-by-layer estimation of cross-section of space, time of free restoration of level of underground waters or of outflow of fluid are measured and volume of space is calculated. Then level of underground waters, depth of lying of underground space and areas of cross-sections of each of layers of space by which its contour is judged are found. EFFECT: improved authenticity of determination of parameters. 4 dwg
