In addition, if there is a description relating to "first", "second", etc. in the embodiments of the present invention, the description of "first", "second", etc. is for descriptive purposes only and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.

Referring to fig. 1, the present invention provides a pipe repair liner 10, wherein the pipe repair liner 10 includes an impermeable layer 11, an anchoring member 12 and a glass fiber layer 13. The barrier layer 11 comprises a first surface and a second surface which are oppositely arranged; the glass fiber layer is glass fiber cloth impregnated with resin, and is attached to the first surface of the impermeable layer; the anchoring parts are arranged in the transverse direction and the longitudinal direction of the first surface of the impermeable layer, and the anchoring parts are embedded in the glass fiber layer.

Specifically, when the pipeline repairing work is carried out, according to the specific condition of the pipeline to be repaired, the pipeline repairing liner 10 is made into a tubular shape which is matched with the pipeline to be repaired, then resin is impregnated, the glass fiber layer 13 is soaked, and the structural layer is formed through solidification. And then the pipe is installed into the pipe to be repaired to carry out the pipeline repairing work. When the pipeline repairing lining is arranged in the pipeline, the first surface is a surface which is contacted with the inner wall of the pipeline, and the second surface is a surface which faces the inside of the pipeline. And the radial direction of the pipe corresponds to the longitudinal direction, and the circumferential direction of the pipe corresponds to the transverse direction.

The barrier layer 11 is made of a polymer material. The high polymer material can be PPR (polypropylene), PVC (polyvinyl chloride), PB (polybutylene), PE-RT (heat-resistant polyethylene), PE (polyethylene), HDPE (high density polyethylene) and the like. Compared with the traditional metal material, the high polymer material has the characteristics of light self weight, corrosion resistance, high compressive strength, sanitation, safety, small water flow resistance, lower cost, safety, convenience and the like. Also, for cost and sanitary safety reasons, a preferred barrier material is HDPE (enhanced high density polyethylene).

Referring to fig. 2 to 3, the transverse spacing L1 between each two anchors 12 is 40mm to 50mm, and the longitudinal spacing L2 is 20mm to 40 mm. Further, the anchoring elements 12 are uniformly distributed on the outer surface of the impermeable layer 11. In one embodiment, the transverse spacing L1 between each two anchors 12 is 44mm, and the longitudinal spacing L2 is 30 mm.

The thickness h2 of the impermeable layer 11 is 1mm to 2mm, the height h1 of the anchoring bond 12 is 7mm to 9mm, the thickness of the glass fiber layer is 9mm to 11mm, and the total thickness of the pipeline repairing lining is 10mm to 12 mm. It is noted that the thickness of the pipe repair liner 10 is required during the pipe repair process. If the thickness is too thick, the water passing capacity of the repaired pipeline is affected. If the thickness is insufficient, the strength is insufficient, and the repair requirement of the large pipeline cannot be met. Also, in order to secure the height of the glass fiber layer 13 to sufficiently fix and support the glass fiber layer 13, the height of the anchor member 12 should be appropriate. In a preferred embodiment, the anchor is 7.5mm high. The glass fiber layer is 2mm to 3mm higher than the anchoring piece, the specific height is adjusted according to the height of the anchoring piece and needs to be higher than the anchoring piece by a certain distance, and uniform and close fit with a pipeline to be repaired is guaranteed.

Referring to fig. 4, the anchoring member includes a first supporting plate 121, a second supporting plate 122 and a connecting member 120, wherein the bottoms of the first supporting plate 121, the second supporting plate 122 and the connecting member 120 are all connected to the first surface of the impermeable layer 11, one side of the connecting member 120 is connected to one end of the first supporting plate 121, the other side of the connecting member is connected to one end of the second supporting plate 122, and the transverse projections of the first supporting plate 121 and the second supporting plate 122 are overlapped. In a preferred embodiment, the first support plate and the second plate are the same shape. In this way, the fixing capacity of the two sides of the anchoring element 12 to the glass fiber layer 13 is the same, and the glass fiber layer 13 can be fixed on the impermeable layer 11 more stably.

The connecting piece is a triangular prism, two side faces of the triangular prism are respectively connected with the first supporting plate and the second supporting plate, the two side faces are intersected to form an edge, the edge is fixedly connected with the first surface of the impermeable layer, and the longitudinal projection of the first supporting plate and the second supporting plate is in an upward gradually-expanding V shape. The connecting member 120, in addition to serving as a connecting member, also serves as a reinforcing table, and solves the problem of easy deformation of the anchoring member 12 to some extent. The first support plate 121 and the second support plate 122 are arranged obliquely, so that the dragging force between the anchoring element 12 and the impermeable layer 11 is reduced.

The included angle between the first supporting plate and the second supporting plate is 30-120 degrees. If the included angle between the first support plate 121 and the second support plate 122 is too large or too small, the height of the anchoring element 12 and the contact area between the anchoring element 12 and the glass fiber layer 13 cannot be ensured well, and the anchoring element 12 is easily damaged due to stress concentration if the included angle is too large. The included angle is too small, and the dragging force between the anchoring piece 12 and the impermeable layer 11 is too large, so that the service life of the pipeline repairing lining is influenced.

The distance from the top of the connecting piece to the first surface of the impermeable layer is less than the distance from the top of the first support plate and the second support plate to the first surface of the impermeable layer. If the connector 120 is too high, the strength and integrity of the resin cured body may be affected.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
