[0002] With the development of cities, the scale of urban underground pipeline networks is constantly expanding. As a result, a large number of underground pipelines have reached or are close to their service life due to their long-term laying. Pipeline repair technology has increasingly attracted attention from all parties. Pipeline repair refers to the use of various technologies to restore the normal use function of damaged and leaking transmission pipelines. Its repair includes two technologies: external anti-corrosion layer repair and internal repair. Pipeline repair technology includes spiral winding method, and spiral winding method generally requires the use of flexible lining.

[0003] According to a Chinese patent with authorized publication number CN217302124U, a flexible liner for pipeline repair is disclosed. Reinforced anchor bars for enhancing the structural strength of the flexible liner are embedded in the bottom of the buckle groove. After the liner pipeline is formed, its compressive strength can be improved by reinforcing the anchor bars. In actual use, the effect of enhancing the structural strength of the flexible liner only by reinforcing the anchor bars is relatively limited. Therefore, during use, the flexible liner structure may be deformed due to insufficient strength of the flexible liner structure, resulting in the flexible liner failing to achieve the expected effect on pipeline repair, thereby reducing the practicality of the existing flexible liner for pipeline repair.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0031] See also Figures 1 to 4 The utility model provides a technical solution: a flexible lining for pipeline repair, comprising a body 1, a mounting plate 2 bonded to the top of the body 1, a plurality of T-shaped positioning ribs 3 fixed to the top of the mounting plate 2, a reinforcing mechanism 200 installed inside the body 1 for improving the structural strength of the flexible lining, and a laying component 300 installed on the top of the mounting plate 2 for spirally buckling and laying the flexible lining;

[0032] Through the coordinated use of the main body 1, the mounting plate 2, and the reinforcing mechanism 200, the structural strength of the lining can be effectively improved during actual use, thereby effectively avoiding the deformation of the flexible lining structure due to insufficient structural strength of the flexible lining, thereby ensuring that the expected effect of pipeline repair can be achieved, and through the coordinated use of the laying component 300, the structural strength of the spiral winding of the flexible lining can be improved to prevent it from coming out under the action of external force, thereby improving the practicability of the flexible lining used for pipeline repair.

[0033] In this embodiment, the reinforcing mechanism 200 is a structure used to improve the strength of the flexible lining structure.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the reinforcing mechanism 200 includes a reinforcing component 201 installed inside the body 1 for reinforcing the structural strength of the flexible liner, and a connecting component 202 installed inside the body 1 for making the connection more stable.

[0035] In this embodiment, the reinforcing component 201 is a structure used to improve the strength of the flexible lining structure.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the reinforcement component 201 includes a thermal insulation layer 2011 sliding on the inner bottom wall of the main body 1, an anti-seepage layer 2012 fixed to the top of the thermal insulation layer 2011, a reinforcement layer 2013 fixed to the top of the anti-seepage layer 2012, an elastic layer 2014 fixed to the top of the reinforcement layer 2013, a plurality of fixed tubes 2015 fixed to the inner bottom wall of the main body 1, a reinforcement rod 2016 slidably connected to the inside of the fixed tube 2015, two stabilizing grooves 2018 respectively opened on the left and right inner walls of the fixed tube 2015, two limit blocks 2017 respectively fixed on the left and right sides of the reinforcement rod 2016, and two fixed plates 2019 respectively fixed on the left and right sides of the thermal insulation layer 2011.

[0037] It should be noted that the bottom of the fixing plate 2019 is slidably connected to the inner bottom wall of the main body 1, and the top of the fixing plate 2019 is in close contact with the bottom of the mounting plate 2, ensuring that the fixing plate 2019 can play a certain supporting role.

[0038] In addition, the top end of the reinforcing rod 2016 is fixed to the bottom of the mounting plate 2, and the bottom end of the reinforcing rod 2016 is in close contact with the inner bottom wall of the main body 1. The structural strength of the flexible lining can be effectively improved through the support of the reinforcing rod 2016 and the fixing tube 2015, making it less likely to deform.

[0039] In addition, the diameter of the reinforcing rod 2016 is equal to the inner diameter of the fixing tube 2015, and the limiting block 2017 is slidably connected to the inside of the stabilizing groove 2018, so that the connection between the reinforcing rod 2016 and the fixing tube 2015 is more stable.

[0040] At the same time, the thermal insulation layer 2011 is a thermal insulation foam particle layer, and the anti-seepage layer 2012 is an anti-permeability membrane, so that the flexible lining has good thermal insulation effect and the effect of preventing liquid penetration. The reinforcement layer 2013 is a glass fiber layer, and the elastic layer 2014 is an elastic fiber layer, which can further effectively improve the structural strength of the flexible lining.

[0041] In this embodiment, the connection component 202 is a structure used to make the connection more stable.

[0042] like Figure 1 , Figure 2 and Figure 4As shown, the connecting component 202 includes a plurality of snap-in blocks 2021 respectively fixed on opposite sides of two fixing plates 2019, a plurality of mounting grooves 2022 respectively opened on the left inner wall and the right inner wall of the main body 1, a plurality of snap-in grooves 2024 opened on the bottom of the mounting plate 2, and an anti-slip sleeve 2023 fixed inside the snap-in groove 2024.

[0043] It should be noted that the length of the clamping block 2021 is equal to the length inside the anti-slip sleeve 2023, and the width of the clamping block 2021 is equal to the width inside the anti-slip sleeve 2023, ensuring that the clamping block 2021 can be installed more stably in the clamping groove 2024 through the anti-slip sleeve 2023.

[0044] In addition, the clamping block 2021 is plugged into the mounting groove 2022 , and the height of the clamping block 2021 is equal to the height of the mounting groove 2022 , thereby ensuring that the clamping block 2021 can be effectively plugged and fixed into the mounting groove 2022 .

[0045] At the same time, the mounting plate 2 and the fixing plate 2019 are both made of rubber, ensuring a certain degree of softness for laying respectively equal to the flexible lining.

[0046] The laying assembly 300 in this embodiment is a structure for laying the flexible liner in a spiral manner.

[0047] like Figure 1 and Figure 4 As shown, the laying component 300 includes a U-shaped block 301 fixed to the top of the mounting plate 2, a triangular block 302 fixed to the right side wall of the U-shaped block 301, a buckle groove 303 opened inside the U-shaped block 301, a boss 304 fixed to the top of the mounting plate 2, a compression sealing strip 305 fixed to the top of the boss 304, a vertical plate 306 fixed to the top of the mounting plate 2, and a convex buckle 307 fixed to the top of the vertical plate 306.

[0048] It should be noted that the shape of the buckle groove 303 is matched with the convex buckle 307 to ensure a more stable connection between the buckle groove 303 and the convex buckle 307.

[0049] The working principle of the above embodiment is:

[0050] When in use, the fixing plate 2019 is placed inside the body 1, the clamping block 2021 is plugged into the mounting groove 2022, and then the mounting plate 2 is bonded to the body 1. At this time, the top of the elastic layer 2014 is in close contact with the bottom of the mounting plate 2. At this time, the reinforcing rod 2016 is located inside the fixing tube 2015, and the top of the fixing tube 2015 is in close contact with the bottom of the mounting plate 2. Under the action of the limit block 2017 and the stabilizing groove 2018, the reinforcing rod 2016 and the fixing tube 2015 are installed more stably, so that under the coordinated use of the reinforcing layer 2013, the elastic layer 2014, the reinforcing rod 2016 and the fixing tube 2015, the reinforcing layer 2013, the elastic layer 2014, the reinforcing rod 2016 and the fixing tube 2015 can effectively improve the stability of the fixing tube 2015. The structural strength of the high-flexible lining can effectively avoid deformation caused by insufficient structural strength of the flexible lining, and the top of the snap-in block 2021 is located inside the snap-in groove 2024, in close contact with the anti-slip groove 203, so that the main body 1 and the mounting plate 2 are more stable, and then the convex buckle 307 of the other flexible lining is inserted into the buckle groove 303 of the flexible lining. Under the action of the triangular block 302 and the buckle groove 303, the convex buckle 307 is stably and effectively inserted into the buckle groove 303, and the compression sealing strip 305 is in close contact with the bottom of the U-shaped block 301, thereby completing the connection between the two flexible liners, thereby realizing the spiral winding buckle of the flexible liner.

[0051] Compared with the prior art, the flexible lining for pipeline repair can effectively improve the structural strength of the lining during actual use through the coordinated use of the main body 1, the mounting plate 2, the reinforcing layer 2013, the elastic layer 2014, the reinforcing rod 2016, the fixing tube 2015 and the clamping block 2021 in the reinforcing mechanism 200, thereby effectively avoiding the deformation of the flexible lining structure due to insufficient structural strength of the flexible lining, thereby ensuring that the expected effect of pipeline repair can be achieved, and through the coordinated use of the triangular block 302 and the convex buckle 307 in the laying component 300, the structural strength of the spirally wound buckle of the flexible lining can be improved to prevent it from coming out under the action of external force, thereby improving the practicability of the flexible lining for pipeline repair and solving the problem of low practicability of the existing flexible lining for pipeline repair.
