METHOD AND DEVICE FOR PULLING RESIN PIPE

摘要

PROBLEM TO BE SOLVED: To reduce a drilled area without damaging an existing pipe nor being affected by an other buried object. SOLUTION: In this method for pulling a resin pipe, vertical holes 10A for working are drilled in both end positions of the existing pipe 4A in a section to be repaired of the existing pipe 4A buried underground, and the resin pipe 1 is drawn in from a one end side to the other end side of the existing pipe 4A by a pulling means 11 installed on the ground so as to line the existing pipe 4A with the resin pipe 1. A supporting means is arranged between the pulling means 11 and an inner wall part 21 so as to receive drawing reactive force acted by drawing in the resin pipe 1 by the pulling means 11 on the inner wall part 21 of the vertical hole 10A for working.
