[0029] refer to Figures 1 to 3 A double-layer inspection well structure according to an embodiment of the present invention is described.

[0030] like Figures 1 to 3 As shown, the double-layer inspection well structure includes a first section 100; a second section 200, which is arranged on one side of the first section 100, and the second section 200 is arranged in the same direction as the first section 100, and the horizontal elevation of the second section 200 is higher than the horizontal elevation of the first section 100, and the second section 200 has a accommodating cavity 210, and the bottom elevation of the accommodating cavity 210 is the same as the horizontal elevation of the first section 100; a manhole cover 300, which is arranged on the first section 100 structure, and the manhole cover 300 at least partially extends into the accommodating cavity 210; a support 400, which is arranged in the accommodating cavity 210, and is used to support the suspended second section 200.

[0031] like Figure 1As shown, the first road section 100 is located in front of the second road section 200. Both the first and second road sections 100 and 200 extend in the left-right direction. A manhole cover 300 is installed on the first road section 100 at the same elevation as the first road section 100. The second road section 200 is located at a higher elevation than the manhole cover 300. The second road section 200 has a receiving cavity 210 at the location corresponding to the manhole cover 300. The manhole cover 300 extends from the first road section 100 into the receiving cavity 210, meaning that the second road section 200 covers a portion of the manhole cover 300. The receiving cavity 210 is provided with a support 400 for supporting the cavity roof structure. Therefore, when widening a motorway, a portion of the manhole cover 300 can be extended into the receiving cavity 210 to avoid large-scale pipeline relocation, reducing construction costs and time, and lowering the investment in the renovation project. Furthermore, by concealing a portion of the manhole cover 300, the overall aesthetics of the road can be enhanced, improving the landscape quality of the urban environment.

[0032] In some specific embodiments of the present invention, the width of the accommodating cavity 210 is greater than the diameter of the manhole cover 300 .

[0033] In some specific embodiments of the present invention, the depth of the accommodating cavity 210 is greater than the length of the manhole cover 300 extending into the accommodating cavity 210 .

[0034] In some specific embodiments of the present invention, a movable cover plate 220 is provided on the second section 200, and the support 400, the movable cover plate 220, the first section 100 and the second section 200 enclose a receiving cavity 210, and the upper end of the support 400 abuts against the movable cover plate 220, and the support 400 is used to support the movable cover plate 220. Figure 1 and Figure 2 As shown, the ceiling of the accommodating chamber 210 is a movable cover 220, the sidewalls of the accommodating chamber 210 are the support 400 or the second section 200, and the bottom wall of the accommodating chamber 210 is the first section 100. Thus, the movable cover 220 solves the height difference between the first section 100 and the second section 200. This not only preserves the existing manhole function, but also facilitates maintenance of the manhole using the movable cover 220.

[0035] In some specific embodiments of the present invention, the support 400 is horizontally arranged and extends along the wall of the accommodating cavity 210. Figure 1 and Figure 3 As shown, the support 400 extends closely against the side wall of the accommodating cavity 210. It should be noted that the accommodating cavity 210 in this specific embodiment is rectangular, and the horizontal cross-section of the support 400 is U-shaped and is arranged below the movable cover 220. Specifically, the outer contours of the support 400 and the movable cover 220 correspond to each other, that is, the movable cover 220 is placed in the limiting groove formed by the support 400, thereby limiting the position of the movable cover 220.

[0036] In some specific embodiments of the present invention, the movable cover 220 includes a plurality of cover units 221, and the plurality of cover units 221 are arranged along a direction perpendicular to the direction in which the second section 200 extends. Figure 1 and Figure 3 As shown, there are two cover units 221 , which are arranged in sequence along the front-to-back direction. Of course, depending on the size of the accommodating cavity 210 , there can be three, four, five or more cover units 221 .

[0037] In some specific embodiments of the present invention, the cover plate unit 221 includes a concrete plate 2211 and a side beam 2212. The side beam 2212 is wrapped around the outside of the concrete. The side beam 2212 corresponds to the support 400. The support 400 is used to limit the position of the concrete plate 2211. Figure 2 and Figure 3 As shown, the concrete slab 2211 is a rectangular slab, and the side beams 2212 are arranged around the side walls of the concrete slab 2211. It should be noted that in order to enhance the stability and bearing capacity of the concrete slab 2211, side beams 2212 are arranged around the periphery of the concrete slab 2211 to strengthen the structure of the concrete slab 2211 and prevent it from cracking or deformation.

[0038] In some specific embodiments of the present invention, the cover unit 221 further includes paving blocks 2213, which are laid on the upper end of the concrete slab 2211. The paving blocks 2213 are used to ensure that the ground of the second road section 200 is flat and stable. Specifically, the paving blocks 2213 correspond to the existing paving blocks 2213 on the second road section 200. On the one hand, laying the same paving blocks 2213 as those on the second road section 200 can make the manhole cover 300 consistent with the surrounding road environment, improve the overall aesthetics, and reduce visual abruptness. On the other hand, using paving blocks 2213 of the same material and design can ensure that the ground around the manhole cover 300 is flat and stable, reducing the risk of people tripping or falling when walking through it.

[0039] In some specific embodiments of the present invention, the second road section 200 is provided with a curb 230, and the curb 230 extends along the length direction of the second road section 200. Figure 1 As shown, curbstones 230 are located on opposite sides of the second road section 200 to provide support for the edge of the second road section 200 .

[0040] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
