Title: Two-stage jacking pipe
Inventor: FURUICHI TOSHIJI
IPC: F16L1/024
Filed: 2000-05-08
Abstract: PROBLEM TO BE SOLVED: To solve the problem that workable distance of a small-bore jacking construction is limited to 100-150 m by adhesive force and friction force being generated around a jacking pipe. SOLUTION: Friction force can be reduced by injecting a lubricant with high viscosity to the gap part between the inner and outer pipes of this two- stage jacking pipe, and also the weight of the jacking pipe can be reduced by buoyancy operating on the inner pipe. Also, by using the two-stage jacking pipe, the driving force up to that point can be nearly returned to zero by the jacking (two-stage jacking) by the inner pipe only when the simultaneous jacking (one-stage jacking) of the inner and outer pipes reaches the limit, thus almost double jacking length as compared with a conventional jacking construction is possible.
