DETAILED DESCRIPTION
[0033] The following will be described in detail in combination with the accompanying Figures 1-3 The present application will be further described in detail.
[0034] The embodiment of the present application discloses a pipe gallery pipeline repair structure, referring to Figure 1 and Figure 2 , comprising an annular glue injection shell 2 sleeved on the outer periphery of the connection of adjacent pipelines 1, the annular glue injection shell 2 wrapping and covering the interface pipe 11 of the connection of adjacent pipelines 1, the annular glue injection shell 2 being spliced by two arc-shaped plates 21, the inner periphery of the arc-shaped plate 21 being provided with an arc-shaped groove 210, the arc-shaped groove 210 being open at both ends, and the arc-shaped grooves 210 of the two arc-shaped plates 21 being spliced to form a ring-shaped groove, the inner periphery of the ring-shaped groove being left with a gap from the outer periphery of the interface pipe 11 between the adjacent pipelines 1. The outer periphery of the arc-shaped plate 21 is connected with a connecting pipe 22, and the connecting pipe 22 is in communication with the arc-shaped groove 210 of the corresponding arc-shaped plate 21.
[0035] When the pipe is repaired later, the sealant can be injected into the annular sealant injection shell 2 through the connecting pipe 22 to fill the leakage between the pipeline 1 and the interface pipe 11; at the same time, the annular sealant injection shell 2 limits the exposure of the filled sealant to the outside, effectively reducing the aging failure of the sealant.
[0036] With reference to Figure 1 and Figure 2 , the connecting lugs 3 are protruded at both ends of the arc-shaped plates 21 and are integrally formed with the arc-shaped plates 21. The connecting lugs 3 at the proximal ends of the two arc-shaped plates 21 are connected by a plurality of connecting pieces, so that the annular sealant injection shell 2 formed by splicing the two arc-shaped plates 21 can be stably sleeved on the outer periphery of the pipeline 1. Specifically, the connecting pieces include connecting bolts 4 and connecting nuts 41; the connecting lugs 3 are provided with through holes 30 corresponding to the connecting bolts 4, the connecting bolts 4 are arranged in the connecting lugs 3 at the proximal ends of the adjacent arc-shaped plates 21 through the corresponding through holes 30, and the connecting nuts 41 are threadedly connected to the tail ends of the connecting bolts 4 and abut against the proximal connecting lugs 3, thereby achieving the connection and fixation of the connecting lugs 3 at the proximal ends of the two arc-shaped plates 21.
[0037] The connecting lugs 3 at the proximal ends of the two arc-shaped plates 21 are respectively provided with positioning protrusions 31 and positioning recesses 32, the positioning protrusions 31 and the positioning recesses 32 are respectively located on the splicing surfaces of the proximal connecting lugs 3 of the two arc-shaped plates 21, and the positioning protrusions 31 and the positioning recesses 32 are inserted and fitted. The positioning protrusions 31 are located on the side of the through holes 30 close to the arc-shaped plates 21, and the positioning protrusions 31 and the positioning recesses 32 extend to both ends of the connecting lugs 3. Through the above arrangement, on the one hand, when the two arc-shaped plates 21 are spliced, the positioning protrusions 31 and the positioning recesses 32 are inserted and fitted, so that the two arc-shaped plates 21 can be quickly positioned, so that the two arc-shaped plates 21 can be quickly positioned relative to each other, which facilitates the splicing of the two arc-shaped plates 21 in place, and on the other hand, the positioning protrusions 31 and the positioning recesses 32 can improve the sealing performance of the connecting lugs 3 at the proximal ends of the two arc-shaped plates 21.
[0038] With reference to Figure 1 and Figure 3 , the two arc-shaped plates 21 are distributed above and below the pipeline 1, and the connecting pipes 22 on the two arc-shaped plates 21 are vertically arranged. Through the above arrangement, when the pipeline 1 is in daily operation, the sewage leaked from the leakage point between the pipeline 1 and the interface pipe 11 can be discharged in time through the connecting pipe 22 located at the lower part of the pipeline 1, which is conducive to avoiding the accumulation of water in the annular sealant injection shell 2, and at the same time, the maintenance personnel can observe the dripping condition of the connecting pipe 22 of the arc-shaped plate 21 located at the lower part of the pipeline 1 to quickly locate the leakage point of the pipeline 1.
[0039] With reference to Figure 1 and Figure 2The check valve 23 is installed at the pipe joint 22 of the upper part of the pipeline 1. During the daily use of the pipeline 1, the check valve 23 can be used to block the pipe joint 22, so as to prevent the sewage leaked from the pipe joint of the pipeline 1 from leaking out through the pipe joint 22 of the upper arc-shaped plate 21, and facilitate the sewage leaked from the pipe joint of the pipeline 1 to be discharged through the pipe joint 22 of the lower arc-shaped plate 21. Before the sealing glue is injected into the annular glue injection shell 2, the check valve 23 installed at the pipe joint 22 of the upper part of the pipeline 1 is removed and installed at the pipe joint 22 of the lower part of the pipeline 1. Then, the sealing glue is injected into the annular glue injection shell 2 through the check valve 23 installed at the pipe joint 22 of the lower part of the pipeline 1, so as to prevent the sealing glue from leaking out through the pipe joint 22 of the lower part of the pipeline 1. The check valve 23 is a spring check valve with a threaded joint. The outer periphery of the pipe joint 22 is provided with an external thread structure, so as to be connected with the check valve 23.
[0040] In the embodiment, the arc-shaped plate 21 is made of transparent acrylic plate, so as to facilitate the observation of the leakage of the pipe joint between the pipeline 1 and the interface pipe 11 through the annular glue injection shell 2. Meanwhile, the filling of the sealing glue can be observed through the annular glue injection shell 2 when the sealing glue is injected into the annular glue injection shell 2. In other embodiments, the arc-shaped plate 21 can also be made of metal or high-strength plastic, such as stainless steel or polycarbonate.
[0041] With reference to Figure 2 The inner concave side of the arc-shaped plate 21 is fixed with a flexible pad 211 through glue. In the embodiment, the flexible pad 211 is a rubber pad. The flexible pad 211 can improve the sealing performance of the connection between the inner concave side of the arc-shaped plate 21 and the outer wall of the pipeline 1, so as to prevent the sealing glue injected into the annular glue injection shell 2 from leaking out through the gap between the inner concave side of the arc-shaped plate 21 and the pipeline 1. Meanwhile, the rigid contact between the arc-shaped plate 21 and the pipeline 1 can be prevented when the two arc-shaped plates 21 are assembled, so as to reduce the damage to the pipeline 1.
[0042] The principle of the embodiment is that, when the pipe joint between the pipeline 1 and the interface pipe 11 leaks, the check valve 23 installed at the pipe joint 22 of the upper arc-shaped plate 21 is removed and installed at the pipe joint 22 of the lower arc-shaped plate 21. Then, the sealing glue is injected into the annular glue injection shell 2 formed by the two arc-shaped plates 21 through the check valve 23 installed at the pipe joint 22 of the lower arc-shaped plate 21, so as to seal the leakage of the pipe joint between the pipeline 1 and the interface pipe 11. Meanwhile, the sealing glue is wrapped by the annular glue injection shell 2, so as to prevent the structure of the sealing glue from being directly exposed to the outside, which can cause the aging and failure of the sealing glue.
[0043] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
