摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method for a lining material of a conduit which dispenses with large extruding equipment corresponding to the diameter of the lining material in manufacturing the lining material by covering the whole outer peripheral surface of a fiber cylindrical body with a synthetic resin film and has a smooth inner face after lining without causing any problem for flowing of fluid.
SOLUTION: The fiber cylindrical body 1 is flatly folded and the synthetic resin film 3 is extruded through a T die 2 in succession and coated on both the flat surfaces 1a, 1b of the fiber cylindrical body 1 to form primary coating layers 5a, 5b. Then, the fiber cylindrical body 1 is flatly folded again so that the once edge part becomes substantially the center of the flat part, and the synthetic resin film 3 is extruded through the T die 2 in succession on both the flat surfaces of the fiber cylindrical body 1 so as to cover the spaces 1c, 1d between the primary coating layers 5a, 5b and so that both edges overlap with the primary coating layers 5a, 5b first to form the secondary coating layers 5c, 5d. As a result, the process, wherein the synthetic resin film is extruded through the T die and coated on the flat surface of the flatly folded fiber cylindrical body, is repeated to cover the whole surface of the fiber cylindrical body with the coating layer to obtain the lining material. Thus, only the extruding equipment of the T die is enough as the equipment for forming the coating layer on the fiber cylindrical body, which allows the lining material to be manufactured at a low cost regardless of the size of the diameter of the fiber cylindrical body.

摘要翻译：解决的问题：提供一种导管衬里材料的制造方法，该制造方法通过覆盖纤维圆柱体的整个外周面而在制造衬里材料时分配与衬里材料的直径相对应的大的挤压设备具有合成树脂膜，并且在衬里之后具有光滑的内表面，而不会导致流体流动的任何问题。解决方案：纤维筒体1平坦地折叠，合成树脂薄膜3依次通过T模头2挤出并涂覆在纤维圆柱体1的两个平坦表面1a，1b上，以形成第一涂层5a ，5b。然后，纤维筒体1再次平坦地折叠，使得一次边缘部分基本上变成平坦部分的中心，并且合成树脂膜3在纤维圆柱体的两个平坦表面上连续地通过T形管芯2挤出主体1，以便覆盖主涂层5a，5b之间的空间1c，1d，使得两个边缘首先与主涂层5a，5b重叠以形成第二涂层5c，5d。其结果是，通过T模挤出合成树脂薄膜并涂布在平坦纤维圆筒体的平坦表面上的工序，用覆盖层覆盖纤维圆筒体的整个表面，得到衬里材料。因此，只有T型模具的挤压设备作为在纤维圆柱体上形成涂层的设备就足够了，这使得衬里材料以低成本制造，而不管纤维筒体的直径如何。版权所有（C）2008，JPO＆INPIT

摘要： PURPOSE:To form a strong lining by a method wherein a lining material is arranged in a duct line to bulge the lining by sending pressure fluid into an expansion tube, pressure steam is sent therein, and after a drain stays, the steam is switched to the other expansion tube to cure a setting cylindrical article through the whole. CONSTITUTION:A lining material 2 is inserted into a duct line, and compressed air is sent into an upper side expansion tube 5a to bulge the lining material 2. When pressured steam is sent into the expansion tube 5a by replacing pressure fluid by the pressured steam, this heat is transmitted to a setting cylindrical article 3 via the expansion tube 5a to cure reaction setting type resin liquid in a SMC composing the setting cylindrical article 3, and the setting cylindrical article 3 is cured. When a drain 7 gathers in the expansion tube 5a, the steam is sent into a down side expansion tube 5b. The expansion tube 5b is bulged thereby and besides, the expansion tube 5a is crushed. Then, the drain 7 is pressed, and all the expansion tube 5a becomes uniform.

摘要： PURPOSE:To prevent entering of water from the outside of a pipe line or a leak of a fluid into the pipe line, by a method wherein an inside tube is arranged on the inside of an SMC cylindrical composite, the outside of which is covered with cloth to which water-repellent processing is applied and a strong lining material is formed of the SMC even if a little water is in the pipe line. CONSTITUTION:An SMC cylindrical composite 3 arranged on the outside of a heat-resistant inside tube is obtained by impregnating a high-strength fiber with a curing resin solution having thickening properties. Since the surface of the cylindrical composite 3 is covered with cloth 4 and the cloth 4 is allowed to permeate through styrene steam to be generated at the time of curing of the SMC, it does not happen that the lining material 1 is softened by leaving the styrene within the SMC. The SMC cylindrical composite 3 consisting mainly of the lining material 1 is cured sufficiently and the lining material having high strength is obtained. Then since water-repellent processing is applied to the cloth 4, water does not obstruct curing reaction and cured sufficiently. Since water is prevented from entering into the cloth 4 from the outside even after cure, even if the cylindrical composite 3 is not dense sufficiently, outside water is not leaked out into the pipe line.

摘要： PURPOSE:To continue a film layer extending over the whole circumference, and to prevent the leakage of a fluid and a resin on inversion insertion by forming the film layer onto the outside surface of a cylindrically shaped cylindrical cloth. CONSTITUTION:Sheet-shaped cloth 4 mainly composed of a nonwoven fabric is rounded cylindrically, and both edge sections of the cloth 4 are superposed, thus forming superposing sections 6. Needle punch is executed within a range exceeding the superposing sections 6, thus joining the superposing sections 6, then shaping cylindrical cloth 2. An airtight film layer 3 consisting of a rubber or a synthetic resin is formed onto the outside surface of the cylindrical cloth 2.

摘要： PURPOSE:To obtain a lining material for a conduit having vibration relieving property, external pressure retention and pressure resistance, and suitable diameter expandability by forming a hermetically sealing layer of rubber or synthetic resin on the outer face of a cylindrical woven fabric made by weaving warps and wafts in a cylindrical shape, disposing as wefts highly rigid yarns in a substantially oriented state inside the cylindrical woven fabric, and engaging the woven fabric in a slackened state. CONSTITUTION:In a lining material 1, a hermetically sealing layer 3 of rubber or synthetic resin is formed on the outer face of an outer cylindrical woven fabric 2, and an inner cylindrical woven fabric 4 is engaged within the fabric 2. The fabric 2 is formed by weaving warps 5 and wefts 6 in a cylindrical shape, and the layer 3 is formed on the outer face of the fabric 2. Since the fabric 4 having the wefts 8 employing highly rigid yarns is slackened, the diameter expansion of the fabric 2 is not disturbed by the rigid yarns, the lining material is suitably diameter-expanded by fluid pressure, and press-bonded to the inner face of a conduit in a state that the rigid yarns are substantially elongated. Accordingly, a pipe of a FRP structure reinforced with the rigid yarns with sufficient thickness is formed inside the conduit.

摘要： PURPOSE:To obtain a lining structure where a lining material resists outside water pressure based on subterranean water or rain water and the water or the rain water does not mix up with the drainage, by a method wherein the lining material obtained by impregnating a fiber reinforced material with a reactive curing type adhesive agent is pierced through the foregoing drainpipe while both sides are turned over by a fluid pressure which is lower than water pressure of the outside of the drainpipe. CONSTITUTION:In the case where, for example, a fitting pipe 3 branches from a branch pipe 1 an elastic ring 5 composed of rubbery elastic material is formed on the inside circumferential surface of the branch pipe 1 in a branch part of the fitting part 3. Then a lining material 6 is pierced through the branch pipe 1 while the lining material 6 is turned by liquid pressure. A lining material 6 comprises an airtight layer 8 composed of rubber or synthetic resin on the outside of a fiber reinforced material 7 such as cylindrical woven fabrics or nonwoven fabrics, to the inside of which a reactive curing adhesive agent is applied and the foregoing fiber reinforced material 7 is impregnated with the adhesive agent. The tip of the lining material 6 is fixed annularly into a manhole 2 of an end part of the branch pipe 1 and the fluid pressure is operated on the rear of an annular stationary part 9 from a pressure vessel 10. Along with adhesion of the lining material to the inside of the branch 1 in this manner a rigid pipe is constituted by curing the adhesive agent.
