Description

Technical Field

[0001] This utility model relates to the field of road manhole cover technology, specifically to an anti-settlement road manhole cover. Background Technology

[0002] With the continuous acceleration of urbanization, the scale of urban road construction is expanding, and the number of manhole covers on roads is also increasing dramatically. As an important part of urban infrastructure, manhole covers are mainly used to cover the openings of underground pipelines, inspection wells, and other facilities, playing a role in protecting underground facilities and ensuring the safety of pedestrians and vehicles. During road use, manhole covers are affected by a variety of factors such as frequent vehicle traffic, vibration, and the natural environment.

[0003] Traditional manhole covers lack an effective buffer structure, and the vibrations generated by vehicles are directly transmitted to the manhole and underground facilities. This not only aggravates the damage to the manhole and underground facilities, but also makes the connection between the manhole and the surrounding soil or concrete less stable. Under repeated vehicle rolling, the soil around the manhole is prone to uneven settlement, causing the manhole cover to sink, damaging the road surface and affecting driving comfort and safety.

[0004] Meanwhile, the lack of reliable support devices when opening and closing the manhole cover makes it difficult to maintain a stable open or closed state after opening. This makes it inconvenient for workers to operate the manhole and poses certain safety risks, such as the manhole cover potentially falling and injuring people. Therefore, an anti-settlement road manhole cover has been proposed. Utility Model Content

[0026] Please see Figure 1-5 A type of anti-settlement road manhole cover mainly consists of a manhole cylinder 1, a manhole cover base 2, a manhole cover 3, and opening and closing components. The manhole cylinder 1 serves as the main supporting part of the entire manhole cover structure, and the manhole cover base 2 is fixedly installed on its top. The manhole cover 3 is set on top of the manhole cover base 2, and the opening and closing components are set at the connection between the manhole cylinder 1 and the manhole cover 3 to realize the opening and closing operation of the manhole cover 3.

[0027] The well casing 1 has an overall ring-shaped structure. The outer wall of the well casing 1 is fitted with a rubber layer 7 that is tightly attached to it. The top of the rubber layer 7 is tightly attached to the bottom surface of the well cover base 2. The bottom of the well casing 1 is also provided with a base plate 5. The top surface of the base plate 5 is tightly attached to the installed rubber layer 7, providing stable bottom support for the well casing 1. The rubber layer 7 can not only play a buffering role, reduce the rigid contact between the well casing 1 and the surrounding soil, and reduce the impact of vibration caused by vehicle movement on the well casing 1, but also prevent groundwater from seeping into the interior of the well casing 1 to a certain extent.

[0028] The manhole cover base 2 also has a circular structure and is fixedly installed on the top of the manhole cylinder 1. The manhole cover base 2 provides a stable installation platform for the manhole cover 3, and a positioning slot 43 is provided at its top. The positioning slot 43 is used to install the retaining shaft 41 on the manhole cover 3, ensuring that the manhole cover 3 can be accurately installed on the manhole cover base 2, so that the manhole cover 3 can rotate around the retaining shaft 41 as the axis to realize the opening and closing operation.

[0029] like Figure 2 , 3 As shown, the base plate 5 is located at the bottom of the well casing 1, and a reinforcing ring layer 6 is provided on its outer side. An inner cavity, spaced apart from the outer wall of the well casing 1, is formed on the inner side of the reinforcing ring layer 6. This inner cavity is filled with a concrete layer 10. Eight support columns 8 are arranged in a circular array on the inner wall of the reinforcing ring layer 6 and fixed to the outer wall of the well casing 1. One end of each support column 8 is fitted with a support cover 81, which is fixed to the reinforcing ring layer 6. The support columns 8 and the concrete layer 10 work together to enhance the structural strength of the bottom of the well casing 1 and improve the overall anti-settlement capability of the well cover. The concrete layer 10 is bonded and fixed to the support columns 8 and the rubber layer 7, further ensuring the stability of the entire structure.

[0030] The opening and closing components include a hinge block 4 and a fixing rod 9. The hinge block 4 is located at the top of the well shaft 1, and a locking groove 42 is provided at its bottom. The locking groove 42 is connected to the positioning groove 43.

[0031] like Figure 5 As shown, the fixing rod 9 can be snapped into the inner side of the engaging groove 42. The top side of the fixing rod 9 is in contact with the bottom surface of the manhole cover 3. When the manhole cover 3 is opened, the fixing rod 9 is snapped into the engaging groove 42, which can support the manhole cover 3 and keep it in a vertical position, making it convenient for workers to carry out underground operations. The central section of the fixing rod 9 is provided with a connecting concave rod 91 that snaps into the positioning slot 43. The bottom end of the connecting concave rod 91 is provided with a fixing clip 92, which snaps into the inner side of the engaging groove 42, ensuring that the fixing rod 9 can be stably fixed in the engaging groove 42, thereby reliably fixing the opening and closing state of the manhole cover 3.

[0032] Working principle:

[0033] Under normal use, the manhole cover 3 covers the manhole cover base 2, serving to seal the manhole opening. When it is necessary to open the manhole cover 3 for underground operations, the operator first rotates the manhole cover 3 upward around the pivot 41 to open it to a certain angle. Then, the connecting concave rod 91 of the fixing rod 9 is inserted into the positioning slot 43, and the fixing clip 92 is engaged with the inner side of the engaging groove 42. At this time, the top side of the fixing rod 9 is in contact with the bottom surface of the manhole cover 3, thereby fixing the manhole cover 3 in a vertical position, which facilitates the operator's work. After the work is completed, the fixing rod 9 is removed from the engaging groove 42, and the manhole cover 3 is lowered to cover the manhole cover base 2 again.

[0034] During vehicle movement, the rubber layer 7 on the outer wall of the manhole 1 acts as a buffer, reducing the impact of vibration on the manhole 1. At the same time, the support column 8 and concrete layer 10 inside the reinforcing ring layer 6 provide strong support for the manhole 1, effectively preventing the manhole cover from settling due to vehicle rolling and ensuring the smoothness of the road and driving safety.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
