Description

  TECHNICAL FIELD The present invention relates to a rehabilitation lining material feeding device, and more particularly, to a rehabilitation lining material feeding device for continuously feeding rehabilitation lining material through a manhole to an existing buried pipe installed in the ground. .

  For example, when existing underground pipes such as sewer pipes installed in the ground are aged or damaged, they can be used to repair or repair the buried pipes. The rehabilitated lining material is fed into the buried pipe and brought into close contact with the inner peripheral surface, and cured by applying light or heat, for example, to form a coating layer made of a curable resin that covers the inner peripheral surface of the buried pipe By doing so, various methods for regenerating the pipe line by the buried pipe have been developed (see, for example, Patent Document 1 and Patent Document 2).

  In the conventional method of regenerating a pipe line by a buried pipe using a retinal lining material made of a curable resin, as a method for introducing a flexible retreaded lining material before curing into an existing buried pipe, for example, an inverted elbow is used. Using a known step feeder provided, while feeding compressed air from a compressed air supply source such as a compressor, the tube-shaped rehabilitation lining material is fed into the buried pipe while being inverted, and is brought into close contact with the inner peripheral surface of the buried pipe In addition to the method, the rehabilitated lining material is drawn into the tube-shaped rehabilitated lining material from the manhole on the feed side toward the manhole on the arrival side, inside the buried pipe installed between these manholes. A method of closely contacting the inner peripheral surface of the buried pipe is generally employed (see, for example, Patent Document 2).

  In a method in which a tubular rehabilitated lining material having flexibility is drawn into the buried pipe and the drawn renewed lining material is brought into close contact with the inner peripheral surface of the buried pipe, for example, it is folded flat and folded several times. Pull out the rehabilitated lining material stored in the material storage box etc. in the stacked state and carried into the area near the manhole on the feeding side from the material storage box etc. while opening the folded state. Connect the wire rope for drawing, which extends from the manhole on the reaching side to the manhole on the feeding side through the buried pipe. After that, for example, by pulling the tip of the rehabilitated lining material into the buried pipe through the wire rope by a pulling means such as a winch installed in the vicinity of the manhole on the reaching side, the inside of the buried pipe from the manhole on the feeding side The rehabilitated lining material is sequentially fed continuously to the inside of the buried pipe over the entire length between the manhole on the feeding side and the manhole on the arrival side. Once the rehabilitated lining material is placed inside the buried pipe, attach a closure lid that can be opened and closed at both ends of the rehabilitated pipe, and compress the compressed air inside the rehabilitated lining material, so that the rehabilitated lining material becomes cylindrical. The outer peripheral surface of the rehabilitated lining material is brought into close contact with the inner peripheral surface of the buried pipe.
