GROUND-WATER TREATMENT METHOD, GROUND-WATER TREATMENT DEVICE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a ground-water treatment method capable of three- dimensionally analyzing ground-water or the like and efficiently collecting the ground-water with the reduced number of borings.;SOLUTION: The ground-water treatment method using curved borings 21 and 22 drills the ground within a range of investigation, and since the investigation such as water-pressure, the velocity of a flowing fluid, a flowing direction or the nature of the soil or the like is made at an optional point in a borehole, and the three dimensional analysis of ground-water or the like is easily made. The ground-water treatment method using the curved borings drills the ground within a range of draining the ground-water, a drain pipe is inserted into the borehole, and since the water collected from the drain pipe is discharged from the end of the drain pipe, the efficient collection of the ground-water can be made with the reduced number of borings.;COPYRIGHT: (C)2004,JPO
