METHOD FOR REGENERATING EXISTING PIPE, PIPING HANDLING MACHINE, PRESSURE PUMP, AND DEVICE FOR SUPPLYING BACK-FILLING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a novel method for generating an existing pipe enabling an injection of highly viscous mortar having a constant viscosity by pipe transportation even when the height difference between the ground and the existing pipe is large, and to provide a pipe-making device structure.

SOLUTION: A single axis eccentric screw-type pump 5 is built at the respective position where a passage of each of pipes 22 and 23 supplying the lowly viscous mortar and an additive increasing the viscosity of the lowly viscous mortar to a back filling material injection machine 10 sags along a vertical shaft 202, and the lowly viscous mortar and the additive are transferred to the back filling material injection machine 10 by operating each respective single axis eccentric screw-type pump 5.
