A repairing method for used fresh water pipe with thermosetting resin immersion PE soft textile reinforce tube using air and water pressure-driven turn inside out insertion device of pipe fixed type.

摘要

The present invention is to invert the tube by pneumatic or hydraulic pressure into the resin liquid impregnated PE soft non-woven reinforcement tube used to renovate the old water and sewage pipe by PE soft non-woven reinforcement tube insertion method In particular, when rehabilitation of old water and sewage pipes, the PE flexible nonwoven fabric reinforcement tube impregnated with thermosetting resin solution is reversibly inserted into water pressure or air pressure after removing the scale inside the old pipe, and then drying the tube after drying. By miniaturizing and reducing the weight of the device, it is possible to shorten the time of working process, reduce the cost of facility investment, reduce the cost of construction by reducing the loss of expensive PE soft nonwoven tube, and improve the process. The conventional method of inserting such a thermosetting resin-impregnated PE soft non-woven reinforcement tube into an old top and sewer rehabilitation pipe mainly includes a hydraulic reversal insertion method and a pneumatic reversal insertion method used in an unexcavated rehabilitation method of an old sewer pipe. It has been constructed. Conventional hydraulic pressure reversal insertion method puts an iron support tower on the ground at the construction site, installs a vertical water supply pipe vertically and fills the water in the water supply pipe continuously to invert the resin liquid impregnated PE soft nonwoven tube at the pressure of head pressure. By inserting, it is easy to be exposed to the electric shock of grounded high-voltage cable tube, the danger of conduction due to traffic obstacle and strong wind. In addition, head pressure and insertion distance are directly proportional to each other, so there is a limit to long-distance construction. In the conventional method, the pneumatic reversal inserting device has a resin-impregnated PE soft non-woven reinforcement tube wound in advance in the winder inside the device to fix the inlet tube, and then blows compressed air (FIG. 7) into the sealed device to form a balloon-like shape. It can be inserted in the old pipe by inverting it into the old pipe. The long distance can be inserted by adjusting the compressed air. However, the 80 ~ 100m impregnated tube should be wound around the device in advance so that the device becomes large and the weight of the resin impregnated tube In addition, the weight is so heavy that the vehicle equipped with the reversing device becomes large, and thus the loss of expensive thermosetting resin-impregnated PE soft non-woven reinforcement tube is increased due to the inaccessible working excavation point. This causes a lot of heat loss in the heat curing operation, which is uneconomical. In addition, the surrogate work vehicle occupies the road in the construction section for a long time there is a disadvantage that causes traffic obstacles.;These two conventional methods are large and inefficient, and the apparatus and method applied to the non-excavation rehabilitation method of sewer rehabilitation rehabilitation method, there is a lot of unreasonable disadvantages to apply to all old and rehabilitation renovation method of water and sewage. Accordingly, the present invention invented a specialized method applied to the purpose of water and sewage old pipe rehabilitation repair method and a pneumatic-hydraulic complex reversal insertion device to reduce the cost of facility investment and shorten the work process by miniaturizing and reducing the reversal insertion device To reduce the loss of expensive thermosetting PE soft nonwoven tube used in the pipe, and to reduce the cost of construction by reducing the thickness of the tube to be suitable for rehabilitation repair of old pipes, it is possible to meet the economic efficiency and construction efficiency.;Pneumatic reversal insertion device.
