[0027] Figures 1 to 3This invention illustrates an embodiment of a sealing structure for the opening of a water inlet hole in an open channel sidewall. The sealing structure includes a bracket 1, an open channel sidewall 2, and a water inlet hole 21 located on the open channel sidewall 2. A plugging material 3 is provided inside the water inlet hole 21. A plugging plate 11 is provided on the bracket 1, and a hook portion 4 is provided at the top of the bracket 1. The hook portion 4 is hung on the top of the open channel sidewall 2. The plugging plate 11 is placed on the water inlet side of the water inlet hole 21. The bracket 1 is fixed to the open channel sidewall 2 above the water inlet hole 21 by a fixing component 5. A water-stopping component 6 is abutted between the plugging plate 11 and the open channel sidewall 2, and the water-stopping component 6 is arranged around the periphery of the water inlet hole 21.

[0028] This sealing structure is used to seal the water inlet side of the water inlet hole 21 when it is opened on the sidewall 2 of the open channel. Specifically, it is sealed on the water inlet side of the water inlet hole 21 by combining the plugging plate 11 with the water-stopping component 6. In this way, the plugging material 3 can be removed from the other side (the dry side) of the water inlet hole 21 to carry out the opening construction, preventing water from entering the water inlet side of the water inlet hole 21 during the opening process, so that the opening work can be carried out under dry conditions. This sealing structure can meet the sealing requirements of the water inlet side of the water inlet hole 21 on the sidewall 2 of the open channel and is easy to install and disassemble.

[0029] Furthermore, such as Figure 2 As shown, in this embodiment, the water-stopping component 6 includes an expansion water-stopping ring 61. The expansion water-stopping ring 61 is disposed on the plugging plate 11, abuts against the side wall 2 of the open channel, and is arranged around the periphery of the water inlet 21. The expansion water-stopping ring 61 is a conventional water-expanding ring or an air-expanding ring. The expansion water-stopping ring 61 can meet the sealing requirements of uneven surfaces and improve the sealing effect.

[0030] Furthermore, in this embodiment, a gasket frame 7 is provided on the plugging plate 11, and an expansion sealing ring 61 is provided on the gasket frame 7. Specifically, the expansion sealing ring 61 abuts against the outer side of the gasket frame 7 and the side wall 2 of the open channel. The gasket frame 7 is a solid frame, and after being fixed on the plugging plate 11, a groove with an opening facing the water inlet hole 21 is formed in its middle.

[0031] Furthermore, in this embodiment, the pad frame 7 is provided with a groove 71 on the side facing the open channel sidewall 2, and the expansion sealing ring 61 is engaged in the groove 71. The expansion sealing ring 61 is engaged in the groove 71 to prevent detachment and to facilitate installation. Preferably, the cross-section of the groove 71 is convex.

[0032] Furthermore, in this embodiment, the water-stopping component 6 also includes a flexible corner sealant 62, which seals the angle between the gasket 7 and the open channel sidewall 2. Sealing the angle between the gasket 7 and the open channel sidewall 2 with the flexible corner sealant 62 improves the water-stopping effect. The flexible corner sealant 62 can be materials such as putty or asphalt.

[0033] Further, in the embodiment, the expansion water stop ring 61 is attached to the pad frame 7, so as to improve the connection strength of the two and further prevent disconnection.

[0034] Further, as shown in Figure 1 and Figure 3 In the embodiment, the operating table 8 is arranged on the hanger 1 and is located below the fixed assembly 5 and above the water inlet hole 21. The operating table 8 is arranged below the fixed assembly 5, so as to facilitate the operator to stand on the operating table 8 to operate the fixed assembly 5.

[0035] Further, in the embodiment, the fixed assembly 5 comprises a lower row of fixing bolts 51 and an upper row of reinforcing bolts 52, and the fixing bolts 51 and the reinforcing bolts 52 are fixedly connected to the open channel side wall 2 and the hanger 1. The upper row of reinforcing bolts 52 is located above the lower row of fixing bolts 51. Specifically, the lower row of fixing bolts 51 and the lower row of fixing bolts 51 are arranged transversely. Preferably, the upper row of reinforcing bolts 52 is close to the top surface of the hanger 1, and the lower row of fixing bolts 51 is close to the operating table 8.

[0036] Further, in the embodiment, the hook part 4 is in a U shape, so as to meet the requirement of being sleeved on the top of the open channel side wall 2.

[0037] Although the present application has been disclosed with reference to the preferred embodiments, it is not intended to limit the present application. Any person skilled in the art, without departing from the technical scheme of the present application, can make many possible changes and modifications to the technical scheme of the present application, or modify equivalent embodiments. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application shall fall within the scope of protection of the technical scheme of the present application.
