The invention according to claim 1 is a hollow pipe reinforcing sheet sticking method for sticking a cylindrical reinforcing sheet in the hollow pipe body in order to reinforce the hollow pipe body. A communication hole, which is a hole that communicates, is provided, and a first wire having flexibility and elasticity passes through the communication hole and the inside of the reinforcement sheet, and is fixed to the distal end side of the reinforcement sheet. Then, a pilot hole which is a hole communicating with the inside of the side surface of the hollow pipe body is formed by a hole making step, and the first wire is placed outside from the communication hole and the pilot hole by a reinforcing sheet insertion step. While holding, the reinforcing sheet is pushed into the hollow pipe together with the reinforcing sheet, and the reinforcing sheet is inserted into the hollow pipe body. Is held at a predetermined position. Thereafter, the reinforcing sheet is pressed against the inner wall of the hollow pipe by applying a force to the inside of the reinforcing sheet by a predetermined pressing force applying means through the front communication hole and the pilot hole in the reinforcing sheet sticking step, The reinforcing sheet is affixed to the hollow pipe inner wall with the adhesive applied to the inner wall and / or the adhesive contained in the reinforcing sheet.
請求項１０に記載の発明は、前記補強シートは予め中空パイプ体内壁に塗布しておいた接着剤により前記中空パイプ体内壁に貼り付けられるものであり、前記孔空け工程の後、前記補強シート挿入工程の前に、前記中空パイプ体の最大内径よりもやや大きく膨らむことができるであって、外周面には接着剤が噴出する接着剤噴出口が形成される小型風船体に可撓性と弾性を有する第四線材を固定し、当該小型風船体の内部に空気を入れるための空気注入管と、前記接着剤噴出口に接着剤を供給する接着剤供給管とが前記パイロット孔から外部に存する状態を保持しつつ、当該小型風船体が縮んだ状態で前記第四線材とともに前記小型風船体を前記パイロット孔から前記中空パイプ体内に押入れる。そして、前記補強シート内部に存する当該小型風船体を前記空気注入管に空気を入れることで膨らませるとともに、前記第四線材を操作して前記小型風船体を前記中空パイプ体内部で移動させ、前記接着剤供給管から接着剤を供給することで、前記接着剤噴出口から噴出する接着剤により中空パイプ体内壁に接着剤を塗布する接着剤事前塗布工程を有するものである。なお、第四線材を空気注入管又は接着剤供給管が兼ねるような構成とする場合もあり得る。 The invention according to claim 10 is characterized in that the reinforcing sheet is affixed to the inner wall of the hollow pipe with an adhesive previously applied to the inner wall of the hollow pipe, and after the perforating step, the reinforcing sheet Before the insertion step, the hollow pipe body can expand slightly larger than the maximum inner diameter, and the outer peripheral surface is formed with an adhesive jet port through which an adhesive jets are formed. An air injection pipe for fixing the fourth wire having elasticity and introducing air into the small balloon body, and an adhesive supply pipe for supplying an adhesive to the adhesive outlet are provided from the pilot hole to the outside. While maintaining the existing state, the small balloon body is pushed into the hollow pipe body from the pilot hole together with the fourth wire in a state where the small balloon body is contracted. And while inflating the small balloon body existing in the reinforcing sheet by putting air into the air injection pipe, operating the fourth wire rod to move the small balloon body inside the hollow pipe body, By supplying an adhesive from the adhesive supply pipe, an adhesive pre-application step of applying the adhesive to the inner wall of the hollow pipe by the adhesive ejected from the adhesive ejection port is provided. In addition, it may be set as the structure which an air injection pipe or an adhesive supply pipe serves as a 4th wire.
