Description

Technical Field

[0001] The utility model relates to the field of road rescue, in particular to a scraping tool for road rescue. Background Art

[0002] The requirements for road engineering technology go beyond simply building high-strength, durable, and comfortable roads at all levels. They also require the ability to efficiently repair roads and maintain transport functionality in the event of sudden damage. Cement concrete patching materials are commonly used in municipal road rescue projects. These materials suffer from several issues: low early strength, poor dimensional stability, and prone to cracking due to shrinkage. Cement calcination consumes significant amounts of energy and releases significant amounts of harmful exhaust gases. The coarse and fine aggregates used in concrete are typically non-renewable resources obtained through destructive mining activities such as mountain blasting and riverbed excavation, making them environmentally and energy-unfriendly.

[0003] To address the shortcomings of cement-based patching materials, existing municipal emergency projects in China Southern Airlines primarily utilize inorganic patching materials made from industrial solid waste, such as slag, steel slag, fly ash, and metakaolin. Inorganic polymers, as high-strength cementitious materials, replace cement, offering not only higher mechanical strength and durability, but also environmentally friendly production and the ability to recycle industrial solid waste, resulting in significant social benefits.

[0004] In municipal road emergency repair projects, whether it is cement concrete repair material or new solid waste repair material, it needs to be flush with the original road surface after pouring. The most widely used road leveling method is to use vibrating equipment such as a vibrating ruler to vibrate the filled road surface. The vibrating equipment can enhance the density of the repair material and hydraulically press the repair slurry to be roughly flush with the original road surface. However, the basic working principle of the vibrating equipment is to install a vibrating motor on a vibrating plate to drive the plate for vibrating compaction, which imposes certain requirements on the construction environment. The lack of power near the construction site will cause inconvenience to the use of the vibrating equipment. At the same time, the motor and alloy ruler of the main part are made of heavy metal, which is not convenient to move and transport. In addition, the power provided by the vibrating motor is strong and the vibrating equipment has high working intensity, which will cause splashing of the repair material during construction, which has an adverse effect on the construction workers and the cleanliness of the construction site. Summary of the Invention

[0005] In view of this, the utility model proposes a scraping tool for road rescue, which effectively ensures that the shape of the road surface in the repair area is as consistent as possible with the original road surface, ensuring driving comfort.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] The road rescue scraping tool of the utility model comprises a scraping unit and at least one connecting unit arranged on the scraping unit, wherein the scraping unit comprises a lower resin layer, an upper resin layer and an isolation layer laid between the lower resin layer and the upper resin layer, wherein both the upper resin layer and the lower resin layer are light-cured resin layers;

[0008] The connection unit includes a connection block and a connection cylinder provided on the connection block. The bottom of the connection block has a connection portion, and the connection portion is solidified in the upper resin layer.

[0009] The beneficial effects are: the scraping unit of the utility model can be prepared on site so that it can completely fit the original road surface, so that the shape of the road surface in the repair area is as consistent as possible with the original road surface, ensuring driving comfort; the upper resin layer and the lower resin layer have high hardness, further ensuring the scraping effect; the isolation layer between the resin layers further improves the strength of the scraping unit, thereby increasing its service life.

[0010] During actual production, the number of connecting units can be determined according to the width of the repair area. When the repair area is wider, there are two or more connecting units. Sufficient external force is applied to the leveling unit through the connecting unit to make it completely fit the road surface during the leveling process.

[0011] Preferably, the connecting portion includes at least one ring of fixed teeth disposed at the bottom of the connecting block, the fixed teeth being tilted relative to the bottom surface of the connecting block, with adjacent fixed teeth tilted in opposite directions. More preferably, the sum of the angles between adjacent fixed teeth and the bottom surface of the connecting block is 180°. This advantageously prevents the fixed teeth from tilting and deforming in the same direction when subjected to tangential forces in different directions, further preventing the fixed teeth from dislodging.

[0012] More preferably, the vertical distance between the tip of the fixing tooth and the connecting block is 1 mm, so as to ensure the embedding depth of the fixing tooth and further ensure the fixing effect of the connecting block and the upper resin layer.

[0013] Preferably, the thickness of the upper resin layer and the lower resin layer is 1 mm, which effectively ensures the mechanical strength and hardness of the scraping unit; the height of the connecting block is 5 mm, and the connecting block is preferably made of vulcanized rubber with deformation properties.

[0014] Preferably, the length of the scraping unit is greater than the width of the repaired road section, and the width of the scraping unit is ≥72mm, ensuring that the repaired width can be scraped in one pass, so that the scraped road surface is consistent in height with the existing road surface, further ensuring the scraping effect of the repaired road surface.

[0015] Preferably, the isolation layer is a glass fiber layer.

[0016] Compared with the existing technology, the scraping unit of the utility model can be prepared on site so that it fits the original road surface as much as possible, so that the shape of the road surface in the repair area is as consistent as possible with the original road surface, ensuring driving comfort; the upper resin layer and the lower resin layer have high hardness, which further ensures the scraping effect; the isolation layer between the resin layers further improves the strength of the scraping unit, thereby increasing its service life.

For those skilled in the art, the specific meanings of the above terms in this utility model can be understood based on specific circumstances.

[0022] like Figure 1-2 As shown, the road rescue scraping tool of the present invention includes a scraping unit and a connecting unit provided on the scraping unit. The scraping unit includes a lower resin layer 1, an upper resin layer 2, and an isolation layer 3 laid between the lower resin layer 1 and the upper resin layer 2. The upper resin layer 2 and the lower resin layer 1 are both light-cured resin layers. The isolation layer 3 is preferably a glass fiber layer to further improve the mechanical strength of the scraping unit.

[0023] The connecting unit includes a connecting block 4 and a connecting cylinder 5 provided on the connecting block 4. The bottom of the connecting block 4 has a connecting portion, which is solidified in the upper resin layer 2, thereby achieving a fixed connection between the connecting unit and the scraping unit.

[0024] The scraping unit of the present invention adopts light-curing resin, which is simple to manufacture and has high mechanical strength. The lower resin layer 1 at the bottom is completely in contact with the original road surface, so that the road surface in the repair area is as consistent as possible with the shape of the original road surface, ensuring the scraping effect and driving comfort; the isolation layer 3 between the resin layers further improves the strength of the scraping unit.

[0025] During actual production, the scraping unit is a rectangular structure with its long side length greater than the width of the repair area and its short side length ≥72mm, ensuring that the scraping unit can completely scrape across the repair area so that the scraped road surface is consistent in height with the existing road surface, further ensuring the scraping effect of the repaired road surface.

[0026] During actual production, the number of connecting units can be determined according to the width of the repair area. When the repair area is wider, there are two or more connecting units. Sufficient external force is applied to the leveling unit through the connecting unit so that the leveling unit can fully fit the road surface during the leveling process to ensure the leveling effect.

[0027] In actual production, the connecting block 4 is made of vulcanized rubber with deformable properties. The connecting part at the bottom of the connecting block 4 is a circle of fixed teeth 6 set at the bottom of the connecting block 4. The fixed teeth 6 are tilted and the tilt directions of the two adjacent fixed teeth 6 are opposite. The fixed teeth 6 are helical teeth, and the two adjacent fixed teeth 6 are symmetrical. The sum of the angles between the two adjacent fixed teeth 6 and the bottom surface of the connecting block 4 is 180°, which can prevent the fixed teeth from tilting and deforming in the same direction, further prevent the fixed teeth 6 from coming out, and ensure reliable connection. For details, see Figure 1 Of course, during actual processing, one of the fixed teeth 6 may be tilted inwards and the other outwards, and so on alternately.

[0028] During actual production, the thickness of the upper resin layer 2 and the lower resin layer 1 are both 1 mm, which effectively ensures the mechanical strength of the scraping unit; the vertical distance between the tip of the fixed tooth 6 and the connecting block 4 is 1 mm, and the fixed tooth 6 is completely solidified in the upper resin layer 2, effectively ensuring the fixing effect of the connecting block 4 and the scraping unit.

[0029] In actual production, the connecting block 4 is preferably made of deformable vulcanized rubber, and its height is controlled to be about 5 mm. The connecting block 4 is a rectangular structure or a circular structure, and the connecting tube 5 is installed in the central area of ​​the connecting block 4.

[0030] The production process of the utility model is as follows: find an area with intact road surface and no obvious slope near the construction section, enclose a rectangular groove in the area, the long side of the rectangular groove is longer than the width of the repaired area, and the short side of the rectangular groove is ≥72mm, to ensure that the scraping unit can completely scrape the repaired area;

[0031] A PET film is laid in the rectangular groove to prevent the formed screed unit from adhering to the road surface; a light-curing resin is poured into the rectangular groove, and a layer of glass fiber cloth is laid on the light-curing resin. Then, an ultraviolet light source is used to penetrate and irradiate the light-curing resin, causing it to completely cure in a short time;

[0032] After the lower resin layer 1 is completely cured, pour the photocurable resin again, insert the fixing teeth 6 at the bottom of the connecting block 4 into the photocurable resin, and ensure that the fixing teeth 6 are completely immersed in the resin, and then use ultraviolet light to cure, thereby achieving a tight connection between the connecting block 4 and the upper resin layer 2; after the upper resin layer 2 is completely cured, the utility model can be taken out.

[0033] In the present invention, the number of connecting units is determined by the area of ​​the scraping unit, ensuring that the entire scraping unit is evenly stressed during the scraping process, so that the scraping unit is close to the ground, further ensuring that the scraped road surface is basically consistent with the original road surface, and driving comfort is guaranteed.

[0034] Compared with the existing technology, the leveling unit of the present invention can be prepared on site so that it fits the original road surface as closely as possible, making the shape of the road surface in the repair area as consistent as possible with the original road surface, ensuring driving comfort; the upper resin layer 2 and the lower resin layer 1 have high hardness, further ensuring the leveling effect; the isolation layer 3 between the resin layers further improves the strength of the leveling unit, thereby increasing its service life.

[0035] Finally, it should be emphasized that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments without inventive effort, or replace some of the technical features therein with equivalents. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
