摘要： PURPOSE:To provide a branch pipe lining method capable of directly performing the airtight connection of a pressure bag and a branch pipe lining material by simple constitution. CONSTITUTION:A pressure bag 7 is attached to the set nozzle 10 attached to a working robot 6 and a branch pipe lining material 1 is provided in the pressure bag 7 and the protrusion 5a provided to the flange 5 of the branch pipe lining material is fitted in the groove 10c formed to the set nozzle 10. By this method, the flange 5 is attached to the set nozzle 10 in a detachable manner and compressed air is supplied into the pressure bag 7 in such a state that the flange 5 is brought into close contact with the peripheral edge of the branch pipe opening part 21a of a main pipe 20 to insert the branch pipe lining material 1 in a branch pipe 21 in a reversed state. After the curable resin infiltrated in the branch pipe lining material 1 is cured while the branch pipe lining material 1 is pressed to the inner peripheral surface of the branch pipe 21, the fitting of the protrusion 5a and the groove 10c are released to separate the working robot 6 and the pressure bag 7 from the branch pipe lining material 1 to apply lining to the branch pipe 21.

摘要： PURPOSE: To form lined tubes having various diameters and cross sections by providing a press roller following the cross-sectional shape of the end section of a shield while the roller is arranged on a wound lining cage and a correction roller 21 which is formed in an arbitrary longly elongated shape and follows the cross-sectional shape in the end section of the shield. CONSTITUTION: A press roller 18 is supported by a movable supporting section 19 and pressed against the internal surface of the end section 16 of a shield by means of a spring 20 so that the roller 18 may follow the cross-section shape of the end section 16. In addition, a correction roller 21 expands the diameter of a wound lined tube 22 formed of a wound lining belt 13 by means of its inclined position and following property through the supporting section 19 and spring 20 and brings the tube 22 into contact with a barrel 5 to be reconstructed. After the tube 22 is protruded from the end section 16, consequently, the tube 22 is expanded to a desired shape by means of the correction roller 21. Therefore, lined tubes having circular and oval cross sections can be created.

摘要： PURPOSE:To provide a method for producing a tubular lining material which is capable of furnishing the desired tubular lining material with ease by inflating a pressure tube to expand a plastic tube and a resin absorbent material into a shape of annular tube, causing the plastic tube to adhere closely to the resin absorbent material and heating them to be fused together. CONSTITUTION:A plastic tube 2 is prepared, an tubular resin absorbent material 1 is passed through within the plastic tube 2 and a highly airtight pressure tube 3 is inserted into the inside of the resin absorbent material 1. Compressed air is fed into the pressure tube 3 and thereupon, due to the pressure of air, the resin absorbent material 1 and the plastic tube 2 (a release sheet 4) are exposed into a shape of annular tube. Then, the inside of the resin absorbent material 1 is subjected to vacuum sucking, the plastic tube 2 (separate type sheet 4) is stuck closely to the outer circumferential face of the resin absorbent material 1. Thereafter, the plastic tube 2 is heated by a heater 9, molten and fused to together with the outer circumferential face of the resin absorbent material 1 successively, the surface of resin absorbent material 1 is coated with the plastic tube 2. Thus, the operations for coating the resin absorbent material 1 with plastic films and hermetically sealing the sutures of the resin absorbent material 1 can be rationalized according to this method.

摘要： PURPOSE:To constitute a lining, which runs appropriately along the inside of a pipe line and is uniform, by a method wherein the lining material is formed of a tube, a sheetlike matter wrapping the outside and a film covering the outside of the sheetlike matter under a peelable state, both side fringes of a sheet molding compound having a width wider than an inner circumferential length of the pipe line are piled up slidably each other and made cylindrical and an outer circumferential length is made smaller than the inner circumferential length. CONSTITUTION:A sheetlike matter 2 is formed of a sheet molding compound which is obtained by piling woven fabric 5 on a mat 6 comprised of a high-strength fiber, into which a curing resin solution 7 is infiltrated for thickening, folded up cylindrically and both ends are piled on slidably each other. A flexible rubber or plastic tube 3 is pierced through the inside of the same, the outside is wrapped peelably by a flexible rubber or plastic film 4 and made into a cylindrical lining material 1 where its outer circumferential length is shorter than the inner circumferential length of the pipe line. When the film 4 is removed by peeling off from the lining material 1, the lining material 1 is bent and pierced through the inside of the pipe line 8, a pressure fluid is sent into the lining material 1 and inner pressure is applied to the lining material 1, the sheetlike matters 2 are slid to each other at superposed part, the outer circumferential length is extended and stuck to the inside of the pipe line 8. Then after a heated fluid is sent into the pipe line and the curing resin solution 7 is cured and stuck to the inside of the pipe line 8, the tube 3 is peeled off and removed.
