Description

Technical Field

[0001] This invention relates to the field of road infrastructure technology, and in particular to a phosphogypsum-based curbstone for preventing vehicles from running off the road and its preparation method. Background Technology

[0002] Curbstones are marker stones placed between the road surface and other structures. Curbstones are required in urban roads, between the median strip and the road surface, between the sidewalk and the road surface, at the edge of the median strip in the center of the highway, at the right edge of the driving lane, or at the outer edge of the shoulder.

[0003] Currently, the main method to prevent vehicles from running off the road is to install guardrails. However, according to national regulations, guardrails are only installed on sidewalks on roads with speed limits of 40 km / h or higher. Furthermore, when a vehicle hits a guardrail, it usually causes the surrounding guardrails to collapse. Therefore, there is an urgent need to develop a type of curb that can prevent vehicles from running off the road.

[0004] Furthermore, most existing curb stones are made of precast concrete or processed stone. Human activities, including production, construction, daily life, and other processes, generate large amounts of solid waste. Accumulated industrial solid waste severely damages the ecological environment, occupies land resources, and pollutes the soil. It not only pollutes surface, groundwater, and atmospheric resources but also causes serious safety accidents. Therefore, the reuse of solid waste is urgently needed. Summary of the Invention

[0005] To address the aforementioned problems, this invention aims to provide a phosphogypsum-based curbstone for preventing vehicles from running off the road and its preparation method.

[0006] The technical solution of the present invention is as follows:

[0011] The second spring, the supporting steel plate, and the limiting steel plate are arranged vertically from left to right on the upper surface of the lower steel plate. The top of the second spring is connected to the non-hook end of the hooked steel bar. When the upper steel plate is moved and limited to the limiting steel plate after being hit by a vehicle, the hooked steel bar is facing the through hole. The top of the supporting steel plate abuts against the upper steel plate. The left and right ends of the second steel bar are connected to the limiting steel plate and the right steel plate, respectively.

Detailed Implementation

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and technical features described in this application can be combined with each other. It should also be pointed out that, unless otherwise indicated, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terms "comprising" or "including" and similar words used in this invention refer to elements or objects preceding the word that encompass the elements or objects listed following the word and their equivalents, without excluding other elements or objects.

[0035] On the one hand, such as Figure 1-5 As shown, the present invention provides a phosphogypsum-based curbstone to prevent vehicles from running off the road, comprising a phosphogypsum-based curbstone shell 1 and an anti-run-off device disposed within the phosphogypsum-based curbstone shell 1;

[0036] The anti-bumping device includes a left steel plate 2, a right steel plate 3, an upper steel plate 4, a lower steel plate 5, a first reinforcing bar 6, a second reinforcing bar 7, a first spring 8, a second spring 9, a hooked reinforcing bar 10, a supporting steel plate 11, and a limiting steel plate 12. The upper steel plate 4 is provided with a through hole 13 through which the hooked reinforcing bar 10 can pass. The height of the limiting steel plate 12 is greater than the height of the supporting steel plate 11.

[0037] The left and right ends of the lower steel plate 5 are connected to the left steel plate 2 and the right steel plate 3 respectively. The left end of the upper steel plate 4 is connected to the left steel plate 2. The right end of the upper steel plate 4 is connected to the left end of the reinforcing bar 6. The right end of the reinforcing bar 6 is connected to the right steel plate 3.

[0038] The left and right ends of the spring 8 are connected to the upper steel plate 4 and the right steel plate 3 respectively, and are arranged parallel to the reinforcing bar 6;

[0039] The second spring 9, the supporting steel plate 11, and the limiting steel plate 12 are arranged vertically from left to right on the upper surface of the lower steel plate 5. The top of the second spring 9 is connected to the non-hook end of the hooked steel bar 10. When the upper steel plate 4 is moved and limited to the limiting steel plate 12 after being hit by a vehicle, the hooked steel bar 10 is facing the through hole 13. The top of the supporting steel plate 11 abuts against the upper steel plate 4. The left and right ends of the second steel bar 7 are connected to the limiting steel plate 12 and the right steel plate 3, respectively.

[0040] In the above embodiment, when the vehicle crashes into the phosphogypsum-based curbstone from the left, the outer shell 1 of the phosphogypsum-based curbstone acts as the first layer of buffer. Then, the left steel plate 2 is impacted and moves to the right, causing the upper steel plate 4 to move to the right. At this time, the reinforcing bar 6 acts as the second layer of buffer. When the reinforcing bar 6 breaks, the upper steel plate 4 moves to the limiting steel plate 12, and the hooked reinforcing bar 10 pops out from the through hole 13, embeds itself under the vehicle to slow down the vehicle speed and hook the vehicle to prevent it from running off the road.

[0041] In one specific embodiment, a reinforcing bar 3 14 is provided between the left steel plate 2 and the lower steel plate 5. In this embodiment, by providing the reinforcing bar 3 14, the buffering effect can be further enhanced through the action of the reinforcing bar, thereby strengthening the deceleration effect on the vehicle.

[0042] In one specific embodiment, multiple reinforcing bars 6 are provided and arranged around the spring 8. In this embodiment, by providing multiple reinforcing bars 6, the buffering effect of the reinforcing bars 6 can be further enhanced, the force required to break the reinforcing bars 6 can be increased, and the protective effect can be improved.

[0043] In one specific embodiment, multiple reinforcing bars 7 are provided and distributed at equal intervals in the vertical direction. In this embodiment, by providing multiple reinforcing bars 7, the stability of the limiting steel plate 12 can be improved, preventing the limiting steel plate 12 from being pushed to the right by the upper steel plate 4, thus preventing the hook reinforcing bar 10 from being directly aligned with the through hole 13 and thus from being able to pop out smoothly.

[0044] In one specific embodiment, the hook end of the hooked steel bar 10 adopts a semi-circular hook or a conical hook.

[0045] In one specific embodiment, spring 8 and spring 9 are both springs with a spring constant of 240-260 kN / m, and all steel plates are high-strength alloy steel plates with a yield strength of 1300-1500 MPa and a thickness of 10 mm. The hooked steel bar 10 is a semi-circular / conical hooked steel bar with a nominal diameter of 16 mm, and steel bars 6, 7, and 14 are steel bars with a nominal diameter of 6 mm.

[0046] In the above embodiments, the spring used requires an impact force of at least 40 km / h from a regular car to be compressed, and the 6mm steel bar used generally requires a speed of 30 km / h from a regular car to break, thus enhancing the buffering effect of the present invention.

[0047] In one specific embodiment, the left steel plate 2 is shot-blasted to enhance its fatigue resistance. It should be noted that in this embodiment, the left steel plate 2 is the side closest to the vehicle, hence the treatment is applied to that side. Alternatively, other steel plates can also be shot-blasted if cost and other factors are not a concern.

[0048] In one specific embodiment, the phosphogypsum-based curbstone casing 1 includes a main casing 101 and a cover casing 102 that accommodate the anti-ejection device. After the anti-ejection device is installed inside the main casing 101, the main casing 101 and the cover casing 102 are connected by cement grout 103. Optionally, the cover casing 102 is L-shaped.

[0049] In one specific embodiment, the phosphogypsum-based curbstone shell 1 is prepared from the following materials: 12-24 parts cement, 10-20 parts phosphogypsum powder, 80-100 parts natural fine aggregate, 50-70 parts 5-10mm crushed stone, 80-100 parts 10-16mm crushed stone, 1-2 parts water-reducing agent, and 20-40 parts water.

[0050] In the above embodiments, using phosphogypsum powder as one of the raw materials enables the recycling and reuse of solid waste materials, providing technical support for ecological environment protection. Furthermore, in the above embodiments, by incorporating natural fine aggregate and two different sizes of crushed stone, the compressive strength of the curbstone can be guaranteed, thereby extending its service life.

[0051] In one specific embodiment, the phosphogypsum-based curbstone shell 1 is prepared by the following steps:

[0052] Cement, phosphogypsum powder, natural fine aggregate, and crushed stone are mixed evenly. Water and water-reducing agent are then added and stirred evenly to obtain a slurry.

[0053] The slurry is loaded into a prefabricated mold for the phosphogypsum-based curbstone shell and then cured at room temperature to obtain the phosphogypsum-based curbstone shell.

[0054] In one specific embodiment, the phosphogypsum-based curbstone shell 1 is prepared by the following steps: 18 parts of cement, 15 parts of phosphogypsum powder, 90 parts of natural fine aggregate, 60 parts of 5-10mm crushed stone, and 90 parts of 10-16mm crushed stone are weighed and mixed. After mixing evenly, 2 parts of water-reducing agent and 30 parts of water are added and stirred evenly to obtain a slurry. The slurry is then poured into a prefabricated mold of the phosphogypsum-based curbstone shell for molding. After molding, it is cured at room temperature for 28 days to obtain the phosphogypsum-based curbstone shell.

[0055] On the other hand, the present invention also provides a method for preparing the phosphogypsum-based curbstone for preventing vehicles from running off the road as described in any one of the above claims, comprising the following steps:

[0056] S1: Prepare the phosphogypsum-based curbstone shell 1 and assemble the anti-ejection device;

[0057] S2: The anti-run-off device is installed inside the phosphogypsum-based curbstone shell 1 to obtain the phosphogypsum-based curbstone that prevents vehicles from running off the road.

[0058] In summary, this invention provides a strong buffer for vehicles and prevents them from running off the road at high speeds, thus ensuring pedestrian safety. Compared with existing technologies, this invention represents a significant advancement.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
