[0024] like Figures 1-6 As shown, the road speed bump structure of the present invention has a pit 11 provided on the road surface 10, and the pit 11 is provided with: a support frame, including a first support plate 21, second support plates 22 are vertically provided on both sides of the first support plate 21, and a third support plate 23 is vertically provided on the side of the second support plate 22; the first support plate 21 and the second support plate 22 are arranged in affixed to the inner wall of the pit 11, the third support plate 23 extends out of the pit 11 and is fitted on the road surface 10, and a limiting groove 12 is provided on the road surface 10 to match the third support plate 23; a cement stabilization layer 31, a first grid layer 32, a coarse sand layer 33, a second grid layer 34, a fine sand layer 35, and an interlocking block layer 36 are laid on the first support plate 21 from bottom to top; the upper surface of the interlocking block layer 36 is arranged in an arc shape.
[0025] The road speed bump structure of the utility model is easy to construct, has low cost, is stable and reliable in structure, has high load-bearing strength, has a long service life, and has a good deceleration effect; it can improve the comfort of vehicles driving over speed bumps, reduce the bumpy feeling of vehicles, ensure the proper safety, and avoid vehicle engine stalling.
[0026] In this embodiment, the pit 11 is in the shape of a rectangular parallelepiped, the depth of the pit 11 is 15-30 cm, and the width of the pit 11 is 60-100 cm. A road speed bump structure is arranged in the pit 11 of the above size, so that the road speed bump structure can be stable and reliable, and has high load-bearing strength.
[0027] By arranging a support frame in the pothole 11, the construction of the road speed bump structure can be facilitated, and the support frame can play a supporting role, so that the road speed bump structure is stable and reliable, and has high load-bearing strength.
[0028] The support frame is an integral part and can be integrally formed through a processing technology, which can make the support frame structure stable and reliable and have a long service life.
[0029] The first support plate 21 is fitted and fixed to the bottom surface of the pit 11. Preferably, a plurality of anchor holes are provided on the first support plate 21, and connecting bolts are fixed in the anchor holes. The first connecting plate 21 is fitted to the bottom surface of the pit 11, and the connecting bolts pass through the anchor holes and are inserted and fixed in the pit 11, so that the first support plate 21 can be fixed to the bottom surface of the pit 11.
[0030] The second support plate 22 is fitted and fixed to the side wall of the pit 11. Preferably, a plurality of anchor holes are provided on the second support plate 22, and connecting bolts are fixed in the anchor holes. The second support plate 22 is fitted to the side wall of the pit 11, and the connecting bolts pass through the anchor holes and are inserted and fixed in the pit 11, so that the second support plate 22 can be fixed to the side wall of the pit 11.
[0031] The third support plate 23 is fitted and fixed to the bottom surface of the limiting groove 12. Preferably, a plurality of anchor holes are provided on the third support plate 23, and connecting bolts are fixed in the anchor holes. The third support plate 23 is fitted to the bottom surface of the limiting groove 12, and the connecting bolts pass through the anchor holes and are inserted and fixed in the limiting groove 12, so that the third support plate 23 can be fixed to the bottom surface of the limiting groove 12.
[0032] like Figure 4 As shown, in this embodiment, the surface of the third support plate 23 is flush with the road surface 10, and no specific limitation is made here.
[0033] Or, as Figure 5 As shown, in other preferred embodiments, the surface of the third support plate 23 is lower than the road surface 10, and the surface of the third support plate 23 is covered and fixed by the road surface 10; on the one hand, the connection and fixation of the third support plate 23 can be strengthened; on the other hand, a gap can be avoided from forming between the third support plate 23 and the road surface 10, and the edge of the third support plate 23 can be avoided from being lifted up, thereby ensuring that the vehicle passes smoothly and preventing the vehicle tires from being worn or blocked by the lifted third support plate 23.
[0034] The cement stabilization layer 31 is 4-7 cm thick, and the coarse sand layer 33 is 4-7 cm thick. Together, these layers form the base layer of the speed bump structure. This thick base prevents the structure from sagging, ensuring its durability. Furthermore, the cement stabilization layer 31 and coarse sand layer 33 ensure layered force transmission, resulting in a stable and reliable structure with high load-bearing strength and a long service life.
[0035] The thickness of the first grid layer 32 is 4-6 mm, and the thickness of the second grid layer 34 is 4-6 mm.
[0036] By arranging the first grid layer 32 and the second grid layer 34 spaced apart from each other, the load-bearing strength of the road speed bump structure can be improved, the force can be dispersed, and the cement stabilization layer 31, the coarse sand layer 33, the fine sand layer 35 and the interlocking block layer 36 can be effectively prevented from being crushed and sunken, so that the road speed bump structure maintains sufficient structural strength and is not damaged by crushing.
[0037] In addition, by providing the first grid layer 32 and the second grid layer 34 spaced apart from each other, the comfort of the vehicle when driving over a speed bump can be improved, the bumpiness of the vehicle can be reduced, and proper safety can be ensured to prevent the vehicle engine from stalling.
[0038] The top surface of the fine sand layer 35 is curved, with a height H2 of 5-10 cm from the highest point of the top surface of the fine sand layer 35 to the bottom surface of the fine sand layer 35. Using fine sand to create an arched shape with a height of H2 creates a smooth, stable structure that is less prone to collapse. The provision of the fine sand layer 35 allows the interlocking block layer 36 to be securely and effectively laid and fixed to the fine sand layer 35, preventing the interlocking block layer 36 from shifting or breaking.
[0039] The maximum vertical distance H1 between the top surface of the interlocking block layer 36 and the road surface 10 is 5-10 cm, which can make the slope gentle, improve the comfort of the vehicle when driving over the speed bump, and reduce the bumpy feeling of the vehicle; in addition, it can also make the interlocking block layer 36 have high load-bearing strength and good deceleration effect.
[0040] like Figure 6 As shown, in another preferred embodiment, a plurality of elastic members 37 are provided in the fine sand layer 35 at equal intervals, and the tops of the elastic members 37 are in contact with the bottom surface of the interlocking block layer 36. The elastic members 37 can play a shock-absorbing and buffering role, improving the comfort of the vehicle when driving over the speed bump and reducing the bumpy feeling of the vehicle.
[0041] The elastic member 37 may be a commonly used elastic component in the technical field. For example, the elastic member 37 may be a cylindrical spring.
[0042] The elastic member 37 can be secured using any common method in the art and is not specifically limited here. For example, flat plates can be welded to both the top and bottom of the elastic member 37, with the top flat plate of the elastic member 37 contacting the bottom surface of the interlocking block layer 36. Alternatively, the top flat plate of the elastic member 37 can be connected to the bottom surface of the interlocking block layer 36, without specific limitation here. The bottom flat plate of the elastic member 37 can contact the top surface of the second grid layer 34, or alternatively, it can be connected to the top surface of the second grid layer 34, without specific limitation here.

Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
