| titleOfInvention | Immersion tube with ordinary temperature hardening type for reinforcement of sewer pope, method for manufacturing and constructing the same |
| abstract | TECHNICAL FIELD The present invention relates to a room temperature curing type impregnated tube for reinforcing a non-excavated sewage pipe, a method of manufacturing the same, and a construction method. A first aspect of the present invention provides an epoxy resin composition comprising: an epoxy resin; Urethane resin; Acrylic resin; Curing agent; Other additives including reaction retarders, curing accelerators; The present invention provides a composition for room temperature curing type impregnated tube for reinforcing a non-excavated sewer pipe. The second aspect of the present invention also provides a process for producing a polyurethane foam, comprising: a raw material mixing step of mixing an epoxy resin, a first liquid containing a urethane resin curing agent, a second liquid containing an acrylic resin and an additive; A press forming process of applying pressure to the mixed raw material mixture by a compression press or a cold isostatic press to form a room temperature curing type impregnated tube for reinforcing a non-excavated sewage pipe; And a drying step of drying the cured product in a dryer at a temperature of 120 to 130 캜 and curing the cured product. The present invention also provides a method of manufacturing a room temperature curing type impregnated tube for reinforcing a non-excavated sewage pipe. According to a third aspect of the present invention, there is provided a method for repairing an untreated sewer pipe, comprising the steps of: Maintenance for repairing unreachable sewer pipe After inspecting the location and shape to repair and entering the sewer pipe to check the obstacles including soil, remove foreign matter in the repair area in the sewer pipe with high pressure jet cleaner A second stage of cleaning; A third step of pulling the room temperature curing type impregnated tube manufactured according to the present invention by hydraulic pressure using a hydraulic device at a position where the room temperature curing type impregnated tube is to be repaired; And a fourth step of expanding and expanding the impregnated tube by applying pressure to the surface-curing impregnated tube mounted on the surface by injecting compressed air into the reinforced impregnated tube composition at room temperature; The present invention also provides a method of constructing a room-temperature-curing impregnated tube for reinforcing an unreachable sewer pipe. According to the present invention, it is possible to maximize unique advantages of each resin by specifically synthesizing a urethane, epoxy, and acrylic composite resin to compensate for the disadvantages of currently used thermosetting resins and to use them without heating at 4 to 40 ° C And has excellent elasticity due to the merits of each resin. Thus, it has a high bending strength and impact strength, excellent non-rigidity, excellent corrosion resistance, excellent heat resistance, excellent workability and viscosity control Is excellent in impregnation property and can produce a uniform product at the time of tube production. Also, since the reaction accelerator is fast after the initiation of reaction and the initial stiffness is excellent, not only the rigidity of the molded product after full curing is high, but also the impregnation speed of the fiber and other non- Impregnation property is excellent. |
