Description

Technical Field

[0001] The present application relates to the technical field of manhole covers, and in particular to a manhole cover that is resistant to slurry impact. Background Art

[0002] There are many underground pipelines in urban construction, such as sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. These pipelines must have an exit to the ground at intervals. In order to avoid the exit affecting the normal passage of pedestrians and vehicles, manhole covers will be installed at the exit.

[0003] Manhole covers can sink over time due to the impact of pedestrians and vehicles. Consequently, technicians have developed a number of manhole covers that can be adjusted to a horizontal position. However, this has led to a new problem: during the grouting process, the flowing slurry can enter the adjustment mechanism and, after solidification, cause the adjustment mechanism to malfunction.

[0004] Therefore, how to prevent the slurry from affecting the adjustment mechanism provided on the manhole cover is one of the problems that need to be solved urgently. Utility Model Content

[0005] The present application provides a manhole cover that is resistant to slurry influence, so as to at least solve the above technical problems existing in the prior art.

[0037] In order to make the purpose, features and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0038] Please refer to Figure 1 and Figure 2The embodiment provides a well lid capable of preventing the influence of grouting material, which comprises a well lid body 1 and a base 2, and the bottom of the base 2 is provided with a plurality of height adjusting mechanisms 3 in the axial direction, and the number of the height adjusting mechanisms 3 is at least three, preferably four, which are uniformly distributed on the bottom of the base 2 in the circumferential direction, and the horizontal state of the base 2 is adjusted by adjusting part of the height adjusting mechanisms 3, so that the horizontal adjustment of the whole well lid is realized.

[0039] In order to realize the final installation, it is also necessary to inject grouting material between the base and the well mouth. The embodiment is provided with a plurality of grouting holes 21 penetrating the base 2 in the circumferential direction.

[0040] In order to prevent the flowing grouting material from contacting the height adjusting mechanisms, as shown in Figure 2 and Figure 3 , the circumferential side of each height adjusting mechanism 3 is provided with a first protection mechanism 4, which comprises a first protection plate 41 provided on the first side of the height adjusting mechanism 3 in the circumferential direction of the base 2, and a second protection plate 42 provided on the second side of the height adjusting mechanism 3, and the first protection plate 41 and the second protection plate 42 extend downward from the bottom of the base 2. Thus, the height adjusting mechanism 3 and the injected grouting material can be isolated, the height adjusting mechanism is prevented from contacting the grouting material, and the normal work of the height adjusting mechanism is ensured.

[0041] In order to further enhance the strength of the base 2, as shown in Figure 2 , the bottom of the base 2 is also provided with a plurality of reinforcing ribs 22 extending in the radial direction at intervals. And the width of the reinforcing rib 22 located at the outer edge of the base 2 is smaller than the width of the reinforcing rib 22 located at the inner edge of the base 2, so that the strength of the base 2 is reinforced, and the grouting material can flow through due to the small width of the outer edge of the base 2. More preferably, the grouting holes 22 are arranged on both sides of the reinforcing rib 22.

[0042] Please refer to Figure 4 , in order to facilitate the opening and closing of the well lid body 1, a movable connecting mechanism 5 is arranged between the well lid body 1 and the base 2, which comprises a connecting groove 51 arranged in the longitudinal direction on the base 2, and a connecting piece 52; one end of the connecting piece 52 is slidably connected with the connecting groove 51, and the other end is rotatably connected with the well lid body 1, so that the well lid body 1 can be prevented from being washed away in extreme weather.

[0043] When the well lid body 1 needs to be opened, the well lid body 1 is only needed to be lifted vertically upward to the state shown in Figure 5 , and then the well lid body 1 is rotated along the arrow at the connecting position of the connecting groove 51, so that the well lid body 1 can be opened.

[0044] Meanwhile, in order to facilitate the lifting of the well lid body 1, as shown in Figure 1 and Figure 5 , the well lid body 1 is provided with a lifting handle 6.As shown, a handle 23 consisting of a concave annular groove is provided on the top of the manhole cover body 1 at a position opposite to the connecting groove 51.

[0045] like Figure 6 As shown, the height adjustment mechanism 3 includes:

[0046] A gasket 31 is provided below the base 2;

[0047] The bidirectional stud 32 has a first end threadedly connected to the base 2 and a second end threadedly engaged with the gasket 31. Figure 7 As shown, by screwing the bidirectional stud 32, the distance between the gasket 31 and the base 2 can be adjusted, and the gasket 31 is in contact with the ground, so that the local height adjustment of the base 2 can be achieved.

[0048] To further enhance the protection of the height adjustment mechanism 3, a second protective mechanism is provided on the gasket 31. This second protective mechanism comprises a protective tube 6 surrounding the bottom of the bidirectional stud 32. The protective tube 6 extends downward from the bottom of the gasket 31 and is integrally formed with the gasket 31. The bottom of the protective tube 6 directly contacts the ground, further preventing slurry from entering.

[0049] It is worth mentioning that in the above solution, the bottom of the protection tube 6 is through, and there is still the possibility of slurry entering. In another embodiment, in order to completely prevent the entry of slurry, the bottom of the protection tube 6 adopts a closed structure design.

[0050] It should be understood that the various forms of the processes shown above can be used to reorder, add, or delete steps. For example, the steps described in this application can be performed in parallel, sequentially, or in a different order, as long as the desired results of the technical solution of this application can be achieved. This is not limited herein.

[0051] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0052] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
