[0039] In the embodiment of the present invention, there are two support top plates 4, which are detachably connected to the corresponding support arc plates 3, and the two support top plates 4 are connected to the ends away from the corresponding support arc plates 3. The support top plates 4 can be connected to the support arc plates 3 by bolts, and two support top plates 4 are provided for easier installation, and the structure is symmetrical.

[0040] More specifically, an adhesive layer 7 is provided between the supporting arc plate 3 and the lining body 1 , and between the supporting top plate 4 and the lining body 1 , so as to improve the sealing performance between the components.

[0041] Furthermore, both ends of the base 2 are provided with stepped grooves 9, and the middle portion of the base 2 is provided with a channel 8 for conveniently arranging lines and pipes.

[0042] Furthermore, Figure 3 As shown, the supporting arc plate 3 includes a first arc plate 31, an edge plate 32, a first connecting plate 33 and a first supporting plate 34. The first arc plate 31 is arranged on the inner side of the lining body 1, and the outer wall shape of the first arc plate 31 is adapted to the inner wall of the lining body 1; the edge plate 32 is arranged at the bottom of the first arc plate 31, and the edge plate 32 is arranged at the step groove 9, and is connected and fixed to the base 2 by fasteners; the first connecting plate 33 is arranged at the top of the inner side of the first arc plate 31, and is inclined upward; the first supporting plate 34 is parallel to the top surface of the base 2 and is detachably connected to the supporting top plate 4.

[0043] The first arc plate 31 , the edge plate 32 , the first connecting plate 33 and the first supporting plate 34 may be integrally formed, or may be fixedly connected by other feasible methods, such as welding.

[0044] More specifically, Figure 4 As shown, the support top plate 4 includes a second arc plate 41, a second connecting plate 42 and a second supporting plate 43. The second arc plate 41 is arranged on the inner side of the lining body 1 and connected to the first arc plate 31. The second connecting plate 42 is arranged on the inner side of the second arc plate 41 and tilted downward. One side of the second connecting plate 42 is connected to the second arc plate 41, and the other side is connected to the second supporting plate 43.

At the same time, a first connecting plate 33 and a second connecting plate 42 are fixedly connected to one side of the two support arc plates 3 and the outside of the two support top plates 4, respectively. Bolts 6 are arranged between the first supporting plate 34 and the second supporting plate 43 to facilitate the installation and disassembly of the support arc plates 3 and the support top plates 4. A groove 8 is arranged on the top surface of the base 1 to facilitate the user to arrange lines or pipelines. Among them, an adhesive layer 7 is arranged between the support arc plates 3 and the support top plates 4 and the lining body 1, so that the sealing between the components is better. At the same time, injection ports 10 are opened on the outside of the support arc plates 3 and the support top plates 4 to facilitate the arrangement of fillers between the support arc plates 3 and the support top plates 4 and the lining body 1 to meet the needs of actual use.
