TRACER TESTING DEVICE AND SINGLE-HOLE TRACER TESTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a tracer inserting device and a single-hole tracer testing method capable of setting a test zone in the heterogeneous ground and optionally setting the water pressure and tracer concentration in the test zone with high precision.;SOLUTION: A boring hole 1 is excavated in the ground 2, and the test zone 3 closed at the upper and lower sections with packers 5 is set. The data of the water pressure of the test zone 3 measured by a water pressure gauge 11 are sent to the servo control 37 of a water supply pump while a fixed quantity of water is lifted by a storage pump 27. A feedback signal is transferred to the water supply pump 21 to control the flow rate of the water supply pump 21, a tracer or the like is inserted into the test zone 3, then water is pumped, and the information of the moving state of the tracer is acquired.;COPYRIGHT: (C)2002,JPO
