CLOSE-FIT PIPES LINING SYSTEM OF TRENCHLESS TECHNOLOGY HAVING MEANS FOR PREVENTING DEFORMATION BY CHANGES OF TEMPERATURE AND APPARATUS THEREBY

摘要

The present invention can be applied to the product produced in the factory by the non-excavation method of inserting the deformation pipe as it is, ensuring quality stability and quality control is easy, and does not require the process of curing the resin in the field compared to other methods It is economical because the construction period can be shortened, and it is economical, and it is suitable for eco-friendliness that does not cause harmful water discharge due to the reduction of buried pipe diameter and does not emit harmful substances. To provide a non-excavated strain pipe insertion method and apparatus having a strain preventing means by a temperature change that can reduce or improve the shrinkage or expansion of the liner that may be caused by a temperature change using a strain preventing means. There is a purpose.;In order to achieve the above object, the present invention is inserted into a liner of a folded and flexible material, which is used as a deformation pipe by using a means of introduction to the existing buried pipe for repair or reinforcement; At least one elastic member is attached to both ends of the buried pipe inner wall and the liner; A packer member is mounted at both ends of the buried pipe in order to seal the buried pipe into which the liner of the folded shape is inserted, the packer member of one side is provided with an injection pipe, and an opposite piper member is provided with a discharge pipe; The fluid supplied from the fluid supply part is injected into the buried pipe through the injection pipe of the packer member and discharged through the discharge pipe, and the liner in a folded form is unfolded by the fluid injected through the fluid supply and the expansion and close contact with the inner wall of the buried pipe is carried out. Become; The packer member is removed after the expansion-contacted liner is cooled; In order to prevent the deformation of the liner is in close contact with the inner wall of the buried pipe to provide a strain pipe insertion method and apparatus for preventing the deformation caused by the temperature change is installed on the inner wall of the liner.;Sewer pipe, deformation pipe, deformation prevention means, liner, water-expandable rubber material, ring member, fluid
