CONSTRUCTION OF WELLS OF VERTICAL DRAINING FROM POLYETHYLENE PIPES FOR IMPROVEMENT OF THE MELIORATIVE CONDITION OF IRRIGATED LAND
Annotatsiya
The filter cage is the main element of the water intake part of the vertical drainage wells, made of polyethylene pipes meets all the criteria for well design. The proposed design of the water intake part of the vertical drainage will allow, according to preliminary estimates, to reduce by 20–25%, the current operating costs, mainly due to lower energy consumption for pumping out water and reducing repair and restoration work on vertical drainage systems. Also in the work for particularly difficult conditions of lithological sections, a selection of the sand-gravel filter is proposed; comparative characteristics of different compositions and designs of filters; their coefficient of efficiency; The calculations of the filter cages of the duty cycles of 10, 12, 15% of polyethylene pipes were performed.
