<p>PURPOSE:To provide a process for regenerating a pipe whereby water leakage and the like from a pipe corroded by aging underground are eliminated in the laid conditions and the efficiency of flow is improved as compared to that before regeneration. CONSTITUTION:Cement mortar is poured into an inner bottom section of a pipe 1 having a water-leaking site 2 to form a base section 3 with smooth surface 3A. Next, half synthetic resin pipe bodies 4 are laid with their open sections 4A upward by splicing them successively, and spliced sections 4B and shell sections 4C in the half bodies 4 are successively equipped with bolts 5 with their heads 5A projected upward. Then, cement mortar is charged into side gaps formed between the inner face of the pipe 1 and the outer face of the half bodies 4. So as to form side wall sections 6 having the upper faces 6A inclined toward the open sections 4A of the half pipe bodies. Thus, the pipe may be regenerated without digging it out of the ground, and at the same time, the efficiency of flow may be improved after regeneration owing to the sectional form of the regenerated pipe.</p> |
