Abstract

PURPOSE: To create a hard layer in the impregnated portion by injecting and impregnating water glass and liquid hardening agent into the ground at the same time first and then water glass and suspensible hardening agent there at the same time.
CONSTITUTION: An impregnating pipe 1 is built by connecting three passages respectively with jet nozzles 8, 9, 10. This impregnating pipe 1 is inserted into an assigned depth under the ground. First, water glass and liquid hardening agent are injected from the 1st and the 2nd nozzle and impregnated into the ground at the same time rotating the impregnating pipe 1 and then they are switched over quickly into the 1st and the 3rd nozzle and water glass and suspensible hardening agent are injected and impregnated at the same time rotating the impregnating pipe 1.
