ADJUSTMENT METHOD AND DEVICE OF OUTSIDE DIAMETER OF CONSOLIDATION BODY IN DEVELOPMENT OF COLUMNAR CONSOLIDATION BODY USING TELESCOPIC PIPE

摘要

PURPOSE: To save labor required for adding to a triple pipe in the case a cylindrical consolidation body is developed in greater depth. ;CONSTITUTION: At least two stirring wings 17a-17c are provided at intervals D to a triple pipe 15 provided to the last step pipe 22 of a telescopic pipe 20, and nozzles 18a-18c are provided to the stirring wings 17a-17c. High velocity jets 19a-19c from the nozzles 18a-18c are made to intersect to develop a cylindrical consolidation body H2 together with a columnar consolidation body H1 as a unit.;COPYRIGHT: (C)1995,JPO
