Abstract: PURPOSE: A method for repairing and reinforcing a drain pipe using resin transfer molding is provided to reduce the period of construction work by using thermosetting resins and to save the costs for construction by excluding a refrigerator car for restraining resin hardening. CONSTITUTION: A fibrous preform(6) having a flexible tube(7) is prepared. A resin pipe having a flexible film for preventing contamination and damage is installed in a drain pipe(5) to be repaired or reinforced. The tube is expanded to closely adhere the fibrous preform to the drain pipe. Both ends of the tube are sealed by caps(14,15) having a gate(12) and an air vent(13). Thermosetting resin is injected to the tube and hardened. The fibrous preform remaining in the drain pipe performs as a protecting film.

Abstract: The present invention relates to a method for repairing and reinforcing an underground pipe. The method of the present invention comprises the steps of inserting an inner mold made of flexible material through the interior of a reinforcing element including a fiber preform surrounded by impermeable inner and outer tubes made of the flexible material and combining the inner mold with the reinforcing element; positioning a combined element, which includes the reinforcing element and the inner mold, into the underground pipe to be repaired and reinforced; injecting and expanding the inner mold with and by high temperature fluid, and brining the reinforcing element into close contact with an inner wall of the underground pipe; injecting the reinforcing element with thermosetting resin; and removing the inner mold after the thermosetting resin has been cured. According to the method of the present invention, there are advantages in that simplification of the processes and reduction of incidental expenses can be obtained since it is not necessary to fasten the cover for injecting the resin and air.

Abstract: A method of repairing or reinforcing worn-out underground buried drainpipes by a resin transfer molding process using both flexible tubes and bagging films is disclosed. In the method of this invention, a reinforcement is primarily inserted into a desired position within a target worn-out drainpipe buried underground. The reinforcement consists of a fiber preform internally having a flexible tube, such as a silicon tube, axially extending along the central axis of the preform and wrapped with an adhesive-coated flexible film as a bagging film to provide protection from sewage or underground water. The flexible tube is, thereafter, expanded to bring the fiber preform into close contact with the interior surface of the target drainpipe. The opposite ends of the reinforcement are sealed with two lids. Thereafter, thermosetting resin is transferred into the fiber preform, thus allowing the fiber preform to be impregnated with the thermosetting resin. The impregnated resin is, thereafter, cured to shape the fiber preform as desired, thus repairing and reinforcing the target drainpipe.
