GROUND IMPROVEMENT MACHINE, METHOD FOR IMPROVING GROUD, AND MULTI PUMPING MACHINE FOR COMPRESSION TRANSPORTING SOLIDIFYING AGENT

摘要

PROBLEM TO BE SOLVED: To provide a ground improvement machine which enables smooth and reliable supply and jet of solidifying agents. SOLUTION: Corresponding to an improved rod 10 which has a plurality of jet holes 11, 11 leaving longitudinal spaces, a system for supplying solidifying agents, which is composed of pumping means 16 for compression transporting solidifying agents and a feeding route 17 transporting and supplying solidifying agents sent from pumping means 16 to jet holes 11, is provided independently to each jet hole 11. A multi pumping machine 20 is suitably used, of which the plural sending out sections 30 equivalent to pumping means 16 are driven by one driving source 42. In this case, each sending out section 30 is detachable independently and the number of sending out sections is made possible to be increased or decreased.
