CLOSE-FIT PIPES LINING SYSTEM OF TRENCHLESS TECHNOLOGY USING MEANS FOR REMOVING PLEAT 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 due to excellent roughness coefficient, and it is suitable for environment-friendly, which does not cause the decrease of water supply capacity due to the reduction of buried pipe diameter, and does not emit harmful substances. Wrinkles of the liner that may be generated at the site of the joint step, etc. can be removed using the wrinkle removal means, and non-excavation using the wrinkle removal means capable of preventing the reduction of the flow rate by removing the wrinkles. It is an object of the present invention to provide a modified tube insertion method and apparatus.;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; 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; The present invention provides a wrinkle removal strain pipe insertion method and apparatus in which wrinkles of the inner wall of the liner inflated and adhered to the inner wall of the buried pipe are removed by introducing the wrinkle removing means into the inside of the liner.;Sewage pipe, deformation pipe, wrinkle removal means, liner, halogen heater, packer member for repair
