Development Oversized Jet Grouting
M. Shibazaki, M. Yokoo, H. Yoshida

This paper discusses the development of a practical jet grouting method capable of obtaining a large diameter exceeding 5 meters, based on fundamental experiments for seeking the relationship between discharging energy and eroding capability, and for originating equipments for creating oversized columns. Authors also refer to a trial execution to find optimal geometrics for contract works and a case history which proves superior o the conventional method.
