Description

Technical Field

[0001] This utility model relates to the field of manhole cover construction technology, specifically to a combined structure of asphalt roadbed and manhole cover. Background Technology

[0002] Manhole covers, also known as sewer manhole covers, have a relatively simple structure. They typically consist of multiple vertical protrusions arranged in a circular array on the outside of the manhole ring. When asphalt is laid, the contact area between the manhole ring and the vertical protrusions increases the bonding strength between the manhole ring and the asphalt subgrade. How to further improve the bonding strength between the manhole ring and the asphalt subgrade is a question that needs to be addressed effectively! Utility Model Content

[0003] The purpose of this invention is to provide a combined structure for asphalt roadbed and manhole cover to solve the above-mentioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A combined structure of asphalt roadbed and manhole cover includes a manhole ring, and a rim is provided along the manhole ring and along the port section, wherein a plurality of extensions are welded to the rim to fit the sidewall of the manhole ring.

[0006] The extension is a trapezoidal structure with its hypotenuse away from the well ring and towards the direction of the edge.

[0007] A rectangular port is provided on the upper surface of the extension.

[0008] Preferably, the inner wall of one side of the extension has rectangular grooves that correspond to the rectangular port, extend to the hypotenuse, and are arranged in a linear array.

[0009] Preferably, a horizontal bar is fixedly provided in the center of the rectangular port.

[0010] Preferably, the crossbar has a triangular structure, with one side of the triangular structure parallel to the rectangular port cross-section.

[0011] Preferably, the extension is made of cast iron.

[0012] In the above technical solution, the asphalt roadbed and manhole cover combination structure provided by this utility model has the following beneficial effects: simple structure, convenient and quick construction, can increase the coverage and contact between the paved asphalt and the extension, thereby increasing the combination strength between the asphalt roadbed and the manhole cover.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] like Figure 1-2 As shown, a combined structure of an asphalt roadbed and a manhole cover includes a manhole ring 1, and a perimeter 11 is provided along the port section of the manhole ring 1. Multiple extensions 2 are welded to the perimeter 11 to fit and connect with the sidewalls of the manhole ring 1. Figure 2 As can be seen, the extension 2 has a trapezoidal structure with its hypotenuse away from the manhole ring 1 and facing the direction of the perimeter 11. When laying the asphalt pavement, a predetermined amount of asphalt is poured into the rectangular port 21 opened on the upper surface of the extension 2. Then, it is compacted by a small road roller, so that the asphalt in the rectangular port 21 overflows from the inner wall of one side of the extension 2 through rectangular grooves 3 that correspond to the rectangular port 21, penetrate to the hypotenuse, and are arranged in a linear array, filling the space between the hypotenuse and the ground.

[0020] Furthermore, in combination Figure 2 It can be seen that a horizontal bar 4 is fixedly installed in the center of the rectangular port 21. The horizontal bar 4 is a triangular structure, and one side of its triangular structure is parallel to the cross section of the rectangular port 21.

[0021] In summary, the construction is convenient and quick, which can increase the coverage and contact between the paved asphalt and the extension 2, thereby increasing the bonding strength between the asphalt subgrade and the manhole cover.

[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
