Description

Technical Field

[0001] The utility model belongs to the technical field of well covers and relates to an anti-slip cast well cover. Background Art

[0002] With the rapid development of urban construction, well covers, as an important part of urban infrastructure, play a crucial role in road safety. There are various types of well covers on the market at present, including but not limited to cast iron well covers, stainless steel well covers, composite material well covers, etc. In order to improve the safety performance of well covers in wet and slippery environments, many well cover designs include anti-slip measures. The common practice is to set anti-slip patterns on the surface of the well cover. These anti-slip patterns can be simple concave-convex lines or complex pattern designs, aiming to increase the friction coefficient of the well cover surface, thereby reducing the risk of pedestrians or vehicles slipping on rainy days or in snowy and icy weather.

[0003] However, although the anti-slip patterns can effectively improve the anti-slip performance of well covers in the initial stage, in actual applications, especially in road environments with heavy traffic and frequent heavy loads, the anti-slip patterns on the surface of the well cover will gradually become smooth after long-term wear. This wear not only affects the aesthetics of the well cover, but more importantly, greatly reduces its anti-slip effect, especially in harsh weather conditions, increasing potential safety hazards. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti-slip cast well cover, with the surface of the well cover filled with concrete, so that it always maintains the same friction coefficient as the road surface and will not reduce the anti-slip performance due to long-term use, being safer in actual use.

[0005] To solve the above technical problems, the utility model provides an anti-slip cast well cover, which includes a well seat and a cover body detachably connected to the upper end of the well seat. An outer support ring is arranged on the outer side of the well seat, and an inner support ring matched with the cover body is arranged on the inner side of the well seat. A lower contact ring matched with the inner support ring is arranged at the lower end of the cover body. A rubber buffer ring matched with the lower contact ring is arranged at the upper end of the inner support ring. A filling groove is arranged at the upper end of the cover body. A number of filling grids are arranged upward in the filling groove. The filling groove is filled with a concrete filling material. The cover body is provided with a cover lifting opening. The lower end of the cover lifting opening passes through the cover body, and the upper end of the cover lifting opening extends out of the concrete filling material and is flush with the upper end of the cover body.

[0006] The utility model is further arranged such that a rotating groove is arranged on one side of the well seat, and a rotating seat rotationally connected with the rotating groove is arranged on the outer wall of the cover body.

[0007] The utility model is further arranged such that a plurality of outer reinforcing ribs are arranged between the outer support ring and the well seat.

[0008] The present utility model is further configured such that lifting holes are provided in two outer reinforcing ribs on opposite sides of the well seat.

[0009] The present utility model is further configured such that a plurality of bottom cover reinforcing ribs are provided at the lower end of the cover body.

[0010] The present utility model is further configured such that the upper plane of the well seat is flush with the upper plane of the cover body, and the upper plane of the filling grid is lower than the upper plane of the cover body.

[0011] The present utility model is further configured such that the concrete filling material is asphalt concrete.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] Firstly, by filling the filling groove of the cover body with a concrete filling material and setting a pattern on its surface, not only can the friction on the surface of the manhole cover be increased, but also the anti-slip performance of the manhole cover can be further improved. Especially in rainy and snowy weather, the risk of pedestrians and vehicles slipping can be significantly reduced.

[0014] Secondly, the present utility model is provided with a rubber buffer ring at the upper end of the inner support ring. When a vehicle passes by, the rubber buffer ring can effectively absorb vibration and impact, avoiding the abnormal noise generated by the traditional manhole cover due to vehicle rolling, improving the driving comfort, and reducing the noise pollution.

[0015] Thirdly, the present utility model uses a concrete filling material to fill the filling groove, which can replace part of the cast iron material. This not only reduces the weight of the manhole cover, but also reduces the consumption of cast iron, helps to reduce the production cost, and improves the resource utilization rate at the same time.

[0016] Fourthly, the lifting opening provided in the present utility model enables the staff to conveniently open the cover body, facilitating the inspection and maintenance of the facilities in the well. At the same time, it also allows the gas in the sewer to be discharged, preventing potential safety hazards caused by gas accumulation. Description of the Drawings
