Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
Example one
The present embodiment will be described in detail with reference to fig. 1 to 5. The lining hose easy to fill with resin according to the present embodiment includes a lining hose body 1 and a resin filling bag 4.
The resin filling bag 4 includes a first filling section 41 connected to the outer side of the end of the lining hose body 1, and a second filling section 42 connected to the resin filling device. The resin filling bag 4 of the present embodiment is made of a transparent film material, and is not limited to a high strength PE film, and films made of other materials are also suitable for the resin filling bag 4 of the present invention. And the diameter of second filling section 42 is less than the diameter of first filling section 41, and the diameter of second filling section 42 suits with the diameter of the output end of resin filling equipment, can be quick rather than looks fixed connection for connect more convenient, improve production efficiency. And leakage of resin during filling is avoided. The resin filled in the lining hose is thermosetting or light-curing resin and can be cured under heating or ultraviolet irradiation.
The lining hose body 1 according to the present embodiment includes:
the first resin absorbent material layer 11 is formed in a tubular shape by hermetically connecting two opposite side edges of a sheet-shaped needle-punched non-woven fabric at a seam by a sealing structure.
A polyester thermoplastic polyurethane film 12 laminated on the outer side of the resin absorbent material layer 11;
the sealing structure of the sheet-shaped needle-punched non-woven fabric comprises a strip-shaped non-woven fabric 13 which is positioned at the inner side of the seam of the first resin absorption material layer 11 and is glued with the needle-punched non-woven fabric, and a mesh belt 14 which is positioned at the outer side of the seam of the first resin absorption material layer 11 and is glued with the needle-punched non-woven fabric; the outside of the webbing belt 14 is also provided with a resin layer 16, the resin layer 16 covering the webbing belt 14.
The first resin absorption material layer 11 is used as a layer of the resin-lined hose, and may be made of any needle-punched non-woven fabric that absorbs thermosetting property or light-curing property. The thickness of the first resin absorbent material layer 1 is generally 0.3 to 10cm in thickness. The needle-punched non-woven fabric has a fluffy structure, and more pores are formed in the needle-punched non-woven fabric, so that more resin can be absorbed.
The polyester thermoplastic polyurethane film 12 is attached to the surface of the first resin absorption material layer 11, so that the first resin absorption material layer 11 can effectively prevent the first resin absorption material layer 11 from permeating to the outer side of the first resin absorption material layer 1 after absorbing resin. And absorbing the resin into the first resin absorption material layer 11, and attaching the resin to the inner wall of the underground pipeline to be repaired through overturning. The polyester thermoplastic polyurethane film is located inside the pipe after the construction is completed because the inside of the pipe needs to be smooth.
The strip-shaped nonwoven fabric 3 used in the sealing structure at the seam of the first resin absorbent material layer 11 is a polyester fiber needle-punched nonwoven fabric, and the webbing 14 used may be a tape-shaped material prepared from polyester filaments or glass fiber filaments. The distance between the edge of the webbing 14 and the seam is at least 5cm, and this distance ensures the strength and the anti-seepage effect of the sealing structure.
Further, the strip-shaped non-woven fabric 13, the braid 14 and the first resin absorption material layer 11 are glued by polyurethane adhesive. The strip-shaped nonwoven fabric 13 and the webbing 14 can be well glued to the first resin absorbent material layer 11.
And after the woven tape 14 is glued with the first resin absorption material layer 1, the outer side of the woven tape 14 is covered with a resin layer 16, and the woven tape is completely covered. The resin layer 16 used is a resin coating or a resin film. The resin layer 16 is provided so as to prevent the resin absorbed by the first resin absorbent material layer 11 from leaking between the webbing and the first absorbent material layer 11. And can guarantee the smoothness of the repaired pipeline inner wall after the construction is finished.
Further, the first resin absorbent material layer 11 is constituted by the first polyester fiber layer 111, the glass filament woven cloth 112 and the second polyester fiber layer 113 which are needle-punched in the present embodiment. The glass fiber filament woven fabric is arranged between the two polyester fiber layers, so that the strength of the resin lining hose can be effectively improved.
Further, the end of the resin-lined hose body 1 provided with the fixing device 2 is adhesively sealed via an adhesive. The number of the fixing means 2 may be determined according to the diameter of the resin-lined hose, and may be 1, 2 or 4, or even more.
The fixing device 2 comprises a bolt 21 penetrating through the end part of the lining hose body 1, the other end of the bolt 21 is provided with a nut 22, and a gasket 23 is arranged between the nut 22 and the lining hose body 1; the gasket 23 is sleeved with the bolt 21; the bolt 21 comprises a nut 211 and a screw 212, and the diameter of the nut 211 and the washer 23 is 3-10 times of the diameter of the screw 212.
Further, the outside of the nut 211 and the washer 23 is covered with a sheet-shaped non-woven fabric 24; the sheet-shaped nonwoven fabric 24 is glued to the resin-lined hose body 1. The sheet-shaped non-woven fabric 24 is covered on the nut 211 and the gasket 23 to prevent the nut 211 and the gasket 23 from damaging the resin-lined hose during use.
Example two
This embodiment will be described in detail with reference to fig. 6 and 7. The present embodiment relates to an easily resin-filled lining hose, which is different from the first embodiment in that:
the end part of the lining hose body 1 connected with the resin filling bag 4 is fixedly provided with a hoisting belt 3 through a fixing device 2. In this embodiment, the bolts 21 also pass through both ends of the sling 3. One end of the sling 3 is positioned between the nut 211 and the resin-lined hose body 1, and the other end is positioned between the gasket 23 and the resin-lined hose body 1. Because the diameter of nut 211 and gasket 23 is great, can be fine fix hoisting belt 3 and resin lining hose body 1 mutually. In the present embodiment, the diameter of the nut 211 and the washer 23 is larger than the diameter of the screw 212. The required hole diameter at the end of the resin-lined hose body 1 can be made small and a large fixing area can be provided.
Further differences are: a second resin absorption material layer 15 in a cylindrical shape is further arranged on the inner side of the first resin absorption material layer 11, and the second resin absorption material layer 15 is a needle-punched non-woven fabric. The needle-punched non-woven fabric constituting the second resin absorbent material layer 15 is a polyester fiber needle-punched non-woven fabric. Can absorb more resin and is used for repairing underground pipelines with different diameters.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
