PLANT FOR PREVENTION OF SEEPAGE OF CONTAMINATED WATER FROM WASTE STORAGE AND METHOD FOR CONSTRUCTION OF DEVICE FOR TRAPPING SEEPED WATER FROM WASTE STORAGE Russian patent published in 1996 - IPC

FIELD: hydraulic engineering, particular, plants preventing filtration of contaminated waster to surrounding ground. SUBSTANCE: plant for prevention of seepage of contaminated water from waste storage 2 includes servicing drift 2 driven under waste storage and device 3 for trapping seeped water; installed with inclination to ground surface from two sides of the servicing drift is device for trapping seeped water. Device is formed by a system of casing pipes 4 and tubing pipes 5. Casing pipes 4 have inlet holes for seeping water. Tubing pipes 5 are accommodated coaxially in casing pipes 4. Pipes 4 are spaced to ensure draining of seeped water in the area between them. Pipes 4 and 5 may be made of separate or jointed lengths. Pipes 5 have outlet holes for supply of washing water to pipes 4 and with inlet holes for discharge of seeped water to pipes 4. Besides, pipes 5 may have inlet nozzles for supply of washing water and with inlet holes for discharge of seeped water to pipes 4. The method for construction of device for trapping seeped water is characterized in that drill holes are made and provided with casing pipes 4 in the ground surrounding the waste storage. These holes are drilled by auxiliary means for drilling holes for oil. Casing pipes 4 have inlet holes for seeped water. Introduced into drilled holes, after lifting of drill pipes are pipes 5. Besides, after lifting of drill pipes, supplied through inlet holes of pipes 4 is solidifying material to ambient ground, and then, pipes 5 are introduced. EFFECT: higher efficiency. 6 cl, 4 dwg
