摘要： PROBLEM TO BE SOLVED: To provide a construction method of an artificial low water permeable layer adopted as a kind of underground water level lowering construction method at underground work of the large depth in the sand ground or the gravel ground having a high underground water level. SOLUTION: A water filling well 3A is arranged in one of the construction object ground, and a pumping well 3B is arranged in the other. At least two aqueous solutions X and Y are simultaneously or separately injected into the ground from the water filling well. Water is pumped up from the pumping well, and a hydraulic gradient is formed in the ground, and an underground water flow is generated to promote permeation. Water permeability of the ground is reduced by generating a fine and water insoluble deposit in the ground by contacting and reacting the two aqueous solutions in the ground. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide a method for washing a rechargeable well while preventing its clogging, by creating negative pressure without causing the collapse of the ground. SOLUTION: A casing pipe 11, a water filler pipe 16 and a water pumping pipe 17 are made of very corrosion resistant material such as stainless to prevent metal corrosion which may cause clogging inside the well casing of the rechargeable well 10. A layer of a filter 12 where the strainer of the well is installed is thickly formed to seal the well 10. Prior to water injection, a sudden negative pressure is produced in the filled well by pumping water using a backwashing water pump 14 installed at the water pumping pipe 17, whereby fine grains 9 around the well causing clogging are forcibly removed prior to the start of a recharging operation.
