CHEMICAL INJECTION TEST DEVICE AND CHEMICAL INJECTABIILTY JUDGMENT SYSTEM USING SAME

摘要

PROBLEM TO BE SOLVED: To judge a filling possibility limit easily at a high accuracy by sampling an unagitated sample of field soil at the ground into which chemical is to be filled by a sampler and using the unagitated sample in a filling test. ;SOLUTION: A resin sampling tube comprising a polycarbonate resin transparent tube body 11 is assembled into a triple tube sampler for sampling, and an unagitated sample 15 of the ground into which chemical is to be injected is stored in the resin sampling tube. Also the resin sampling tube in which the unagitated sample 15 is stored is installed as a filling test mold 10 on a chemical filling test device 1. Then during and after the filling of the chemical, the filling condition into the filling test mold 10 is checked visually so as to judge the filling possibility limit of the ground into which chemical is to be filled. By this, before the chemical is filled, the filling possibility limit can be judged easily at high accuracy, and a cost and time required for the investigation on chemical injection can be reduced remarkably.;COPYRIGHT: (C)1997,JPO
