Description

Technical Field

[0001] The invention relates to the technical field of road construction, in particular to a high-strength and durable high curbstone for roads and a manufacturing method thereof. Background Art

[0002] In modern road construction, high curbs are one of the important infrastructures, mainly used to separate the carriageway from the sidewalk, and also play a role in protecting the edge of the road. The existence of high curbs not only improves the safety of the road, but also beautifies the urban landscape to a certain extent. However, the traditional high curbs currently used generally have some technical defects, mainly manifested in insufficient strength, easy damage, poor durability and other problems. Due to the limitations of materials and design, high curbs often crack, shift, peel off and other phenomena after being hit by vehicles or experiencing various natural environmental factors (such as heavy rain, freezing, etc.). This not only affects the overall appearance of the road, but also brings safety hazards to passing pedestrians and vehicles. Especially in areas with large traffic volume, damaged high curbs may become potential traffic danger points, increasing the risk of vehicle collision. At the same time, the manufacturing process of traditional high curbs is relatively complicated, requiring high labor and material costs, further increasing the economic burden of road construction. Therefore, improving the design, materials and manufacturing process of high curbs to improve their strength and durability is one of the problems that need to be solved in current road engineering, which will have an important positive impact on urban traffic and environmental safety.

[0003] Currently, no effective solution has been proposed for the problems in the related technologies. Summary of the invention

[0006] Furthermore, in order to enable adjacent high side stone bodies to be tightly connected under the action of the concave-convex component and improve the overall stability, the concave-convex component includes a protrusion arranged at one end of one of the high side stone bodies, and a groove matching the protrusion is opened at one end of the other high side stone body.

[0007] Furthermore, in order to increase the shock resistance under the action of the rubber convex strips and rubber strip grooves, a plurality of rubber convex strips are arranged at the top and bottom ends of the protrusion, and rubber strip grooves matching with the rubber convex strips are opened at the inner top and bottom ends of the groove.

[0008] Furthermore, in order to enable the filter mesh in the filter trough to effectively intercept garbage and debris and prevent them from entering the drainage ditch under the action of the drainage trough and the filter mesh, reduce the risk of clogging of the drainage system, and thus increase the service life of the drainage facilities, a drainage trough is opened at the bottom of one side of the high side stone body, and the bottom of the drainage trough is on the same horizontal plane as the road surface, one side of the drainage trough is connected to the filter trough, and a filter mesh is arranged at the inner bottom of the filter trough.

[0009] Furthermore, in order to allow the water flow to be quickly guided from the road surface to the drainage system under the action of the drainage ditch and the outlet trough, the height difference on one side of the drainage ditch further ensures the smooth flow of water, which is naturally discharged from high to low, reducing the possibility of water accumulation on the road surface. A drainage ditch is provided on the side of the filter mesh away from the drainage ditch, and an outlet trough connected to the drainage ditch is provided on one side of the high side stone body, and several outlet troughs are arranged along the length of the drainage ditch, and the side of the drainage ditch close to the drainage ditch is higher than the side connected to the outlet trough.

After the concrete solidifies, demoulding is performed, and the surface of the high side stone body is ground and polished to make its surface smooth and flat; S3. Process the side walls at both ends of the high side stone body by mechanical processing or mold forming to form concave and convex components for connection of adjacent high side stone bodies.

[0011] The beneficial effects of the present invention are: 1. The high curb stone of the road of the present invention has the characteristics of high strength and good durability, can effectively resist the impact of vehicle collisions and natural environmental factors, reduce the damage and replacement frequency of curb stones, and reduce road maintenance costs.

[0020] In one embodiment, for the above-mentioned protrusion 201 and groove 202, the top and bottom ends of the protrusion 201 are provided with a plurality of rubber convex strips 2011, and the inner top and inner bottom ends of the groove 202 are provided with rubber strip grooves 2021 that cooperate with the rubber convex strips 2011, so that the anti-seismic performance can be increased under the action of the rubber convex strips 2011 and the rubber strip grooves 2021.

[0021] In one embodiment, for the above-mentioned high side stone body 1, a drainage groove 4 is opened at the bottom of one side of the high side stone body 1, and the bottom of the drainage groove 4 is on the same horizontal plane as the road surface, and a filter groove 5 is connected to one side of the drainage groove 4. A filter mesh 6 is arranged at the inner bottom of the filter groove 5, so that under the action of the drainage groove 4 and the filter mesh 6, the filter mesh 6 in the filter groove 5 can effectively intercept garbage and debris to prevent them from entering the drainage ditch 7, thereby reducing the risk of blockage of the drainage system and improving the service life of the drainage facilities.

[0022] In one embodiment, for the above-mentioned drainage ditch 4, a drainage ditch 7 is provided on the side of the filter mesh 6 away from the drainage ditch 4, and a water outlet ditch 8 connected to the drainage ditch 7 is opened on one side of the high side stone body 1, and a plurality of water outlet ditch 8 are arranged along the length direction of the drainage ditch 7.

[0023] According to another embodiment of the present invention, Figure 6 As shown, a method for manufacturing a high-strength and durable high curb stone for roads is also provided, and the method for manufacturing a high-strength and durable high curb stone for roads comprises the following steps: S1, prepare high-strength concrete material, mix the high-strength concrete material according to a preset ratio, and pour the mixed concrete material into a mold in which a steel mesh 3 is pre-placed; Specifically, high-strength concrete materials include: cement, sand, gravel, admixtures, etc.

[0024] S2, after the concrete solidifies, demoulding is performed, and the surface of the high side stone body 1 is ground and polished to make its surface smooth and flat; S3, processing the side walls at both ends of the high side stone body 1 by mechanical processing or mold forming to form a concave-convex component 2 for connecting adjacent high side stone bodies 1.

[0025] It should be explained that, in order to facilitate understanding of the above technical solution of the present invention, the method for manufacturing high-strength and durable high curbstones of roads in the actual process of the present invention is described in detail below.

[0026] Step 1: Prepare high-strength concrete materials. Use ordinary Portland cement with a grade of 42.5. Use machine-made sand and crushed stone with a particle size range of 0.35mm~0.5mm. Use retarders and expansive agents as admixtures. The amount of retarder is about 0.01%-0.2% of the cement mass, and the amount of expansive agent added is usually 8%-12% of the cement mass.

[0027] Step 2: Mix cement, sand and stone in a ratio of 1:2:3 and stir evenly.

[0028] Step 3: Make a mold for the high side stone body 1, the internal dimensions of the mold are 100 cm long, 30 cm wide and 50 cm high. Place three layers of steel mesh 3 in the mold in advance, and the steel mesh 3 is woven from steel wire with a diameter of 12 mm.

[0029] Step 4: Pour the mixed concrete material into the mold, and use the mold forming method (vibration compaction technology) to press the concrete material into the mold so that its density meets the requirements.

[0030] Step 5: After the concrete solidifies, demoulding is performed. After demoulding, the high side stone body 1 is subjected to surface treatment by spraying an anti-corrosion coating to improve the corrosion resistance of the side stone.

[0031] Step 6: Process the connection part of the high side stone body 1 by using mold forming to form a special concave-convex structure (i.e., concave-convex component 2) on the side of the side stone. The concave-convex depth is 20 cm, the width is 20 cm, and grooves are opened in the middle and lower parts.

[0032] Step 7: The surface of the high side stone body 1 is sandblasted or burned, and then water jet cut to produce various shapes.

[0033] Specifically, water jet cutting technology can be used on the facade of the high side stone body 1. Water jet cutting uses high-pressure water flow to carry abrasives for cutting, and can accurately cut various complex curve shapes. Before cutting, it is necessary to design the curve pattern through computer-aided design (CAD) software and import it into the control system of the water jet cutting equipment. During the cutting process, the water flow pressure is generally controlled at 300-400MPa, and the abrasive is usually garnet sand with a particle size of about 80-120 mesh, which can ensure the cutting accuracy and efficiency.

[0034] To sum up, with the help of the above-mentioned technical scheme of the present invention, the high curb stone of the road of the present invention has the characteristics of high strength and good durability, can effectively resist the influence of vehicle collision and natural environmental factors, reduce the damage and replacement frequency of curb stones, and reduce road maintenance costs. Moreover, under the action of the concave-convex component 2, adjacent high curb stone bodies 1 can be tightly connected while being easy to adjust their positions. At the same time, under the action of the rubber convex strips 2011 and the rubber strip grooves 2021, the seismic resistance is enhanced, and the overall stability and safety of the road are improved. The manufacturing method is simple and easy, with low cost, and is suitable for large-scale production. The present invention arranges a steel mesh inside the high side stone body to increase the crack resistance, and a concave-convex component 2 is arranged at the connecting part, and the concave-convex component 2 is arranged with rubber, which not only strengthens the connection but also improves the seismic resistance. By arranging the drainage ditch 4 and the filter mesh 6, it can prevent garbage blockage and realize the drainage function, so that under the action of the drainage ditch 7 and the outlet ditch 8, the water flow can be quickly guided from the road surface to the drainage system. The height difference on one side of the drainage ditch 7 further ensures the smooth flow of water, which is naturally discharged from high to low, reducing the possibility of water accumulation on the road surface. In addition, the outer facade of the high side stone body 1 adopts water jet cutting technology, which can accurately make various shapes.
