Embodiment Construction
[0069] see Figure 10 , Figure 10A and Figures 11A to 11D , the first embodiment of the anti-theft and anti-jumping well cover device of the present invention includes a well cover 1, and several blind holes 11 are provided on the well cover 1, and the blind holes 11 at least include a clamping surface 111 and a bottom surface 112, and the clamping surface 111 In principle, a vertical surface is suitable, and in a preferred embodiment, the clamping surface 111 is slightly inclined and has an angle α inwardly or outwardly, such as Figure 11D As shown, if necessary, an anti-slip means such as a rough surface or a concave-convex surface can be added on the vertical surface or inclined surface to make the clamping force better for it, that is, the clamping surface 111 can be provided with a rough surface. Surface or concave-convex surface and other anti-slip means are used to stabilize the clamping effect of the clamp. Therefore, the α angle of the aforementioned clamping sur...

The invention discloses an anti-theft and anti-jumping manhole cover device, which comprises a manhole cover, and the well cover is provided with more than one concave-convex groove block, and the concave-convex groove block has a clamping surface for opening and closing of a spreader. The clamping surface of the concave-convex groove block is one of a vertical surface and an inclined surface, and the clamping surface may have an anti-slip structure. The shape of the concave-convex groove block can be any one of circular, rectangular, triangular, polygonal or circular. The concave-convex groove block can be a downward blind hole, and sealant, gypsum or other fillers are poured into the blind hole. It can also be an upward convex groove block, and the reinforced concrete filler is filled in the groove formed between each convex groove block. The manhole cover device of the present invention can make the thief find no point of effort to open the manhole cover when stealing the manhole cover, so that the manhole cover does have an anti-theft function in use, thereby ensuring the safety of the road surface and avoiding danger.
Description
technical field [0001] The invention relates to an anti-theft and anti-jumping manhole cover device. Background technique [0002] By the way, in modern construction projects, many pipelines and facilities are undergrounded to protect the safety of people and vehicles on the road, reduce their interference with people's lives, and increase the beauty of the cityscape. However, the use of any underground pipelines and facilities will inevitably require maintenance or expansion installations, so manhole covers and cover seats must be buried in appropriate locations to facilitate the aforementioned work. However, because the material of the manhole cover and the cover seat is good in texture, durable, and rich in economic value, it becomes one of the favorite prey of thieves because it cannot be monitored all the time. [0003] The current manhole covers are equipped with holes or related facilities for opening the manhole covers, so as to facilitate the opening of the manhole...
