PIPE GUIDE MECHANISM FOR NON-OPEN-CUT PIPE LAYING METHOD

PROBLEM TO BE SOLVED: To provide a pipe guide mechanism wherein when a pipe is brought into a borehole formed in the ground from an arrival shaft, the pipe can be guided so that the axial line thereof is completely aligned with that of the borehole in the arrival shaft. SOLUTION: In the non-open-cut pipe laying method wherein a pipe is brought into a borehole from within an arrival shaft excavated on an end of the borehole formed in the ground, guide plates G3, in pairs, are disposed in the 1 arrival shaft in opposition to each other, spaced apart a predetermined interval, so as to slidably contact the upper and lower parts of a pipe T respectively, thereby vertically positioning the pipe, and guide plates, in pairs, are disposed in the arrival shaft in opposition to each other, horizontally spaced apart a predetermined interval, so as to slidably contact the left and right sides of the pipe T brought into the borehole respectively, thereby horizontally positioning the pipe.
