Abstract

PURPOSE: To provide a construction method which can shorten the period for digging and building as compared with the conventional construction method by injection of chemical agents, thereby shortening the entire construction period of plant, etc.
CONSTITUTION: Underwater digging (excavation without timbering) is made in the ground as it is by a given depth h of the structure without sheet pile outside the structure and injection of chemical agents (cement milk layer). Then, sand, etc. is placed into the section so dug above the ground-level 2 to build the structure 4 on the sand. After completion of the structure, it is made to subside to a given depth by removing sand at the bottom little by little.
