GROUND INFILTRATION TEST DEVICE AND GROUND INFILTRATION TESTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a ground infiltration test device capable of performing a test irrespective of size of infiltration capacity.;SOLUTION: A ground infiltration test device includes: waterworks 1; a flow channel 2 for supplying liquid which supplies water to be supplied from the waterworks 1 to a test hole H; a flow rate sensor 312 which is provided to the flow channel 2 for supplying liquid to measure flow rate of water to be supplied to the test hole H; a displacement detection sensor 5 which detects a level of water to be supplied to the test hole H; a flow rate control valve 313 which controls the flow rate of water to be supplied to the test hole H on the basis of a signal to be output from the displacement detection sensor 5; and a CPU board 321 which records variation of the liquid to be supplied to the test hole H with lapse time. Water is intermittently transmitted from the waterworks 1 to the test hole H, and an amount of the liquid to be supplied to the test hole H is adjusted by the flow rate control valve 313.;COPYRIGHT: (C)2013,JPO&INPIT
