[0002] In the development of road construction and maintenance, the requirements for pavement performance and durability are constantly increasing. Traditional pavement treatment methods have limitations in some aspects, such as the inability to effectively solve problems related to waterproofing, skid resistance, and wear resistance, while construction efficiency and quality also need improvement.

[0003] With advancements in materials science and construction technology, cold-mix emulsified asphalt seal technology has emerged. Cold-mix emulsified asphalt seal is a mixture of emulsified asphalt, aggregates, fillers, water, and additives in a specific ratio, which is then evenly spread onto the road surface using a paving box to form a thin and uniform seal layer.

[0004] Early road treatment methods may have included simple surface coatings or localized repairs, but these methods often failed to provide comprehensive protection and improvement. Cold-mix emulsified asphalt seal technology, on the other hand, can better fill tiny cracks and voids in the road surface, enhancing its overall integrity and stability.

[0005] Furthermore, the increasing traffic volume and heavier vehicle loads place higher demands on the wear resistance and skid resistance of roads. The design and improvement of cold-mix emulsified asphalt seal pavers aim to meet these evolving needs, improve construction precision and efficiency, and ensure that cold-mix emulsified asphalt seals are laid uniformly and with high quality on the road surface.

[0029] Example 1:

[0030] As shown in Figures 1 to 4, a cold-mix emulsified asphalt paving box includes a box frame 2. The box frame 2 is provided with multiple slipper structures and a symmetrically arranged hydraulic system 5. Inside the box frame 2, there are symmetrically arranged handrails 8, a material distributor 10, multiple sets of spiral mixing devices 11, and a central paving box 12. The handrails 8 are provided with a control system 7. The hydraulic system 5 is used to drive the position of the multiple sets of spiral mixing devices 11. The rear side of the box frame 2 is provided with a scraping system 17.

[0031] The aforementioned sliding shoe structure includes two side sliding shoes 1 symmetrically arranged on both sides of the box frame 2 and a central sliding shoe 15 located in the middle of the box frame 2;

[0032] The multiple sets of spiral stirring devices 11 are symmetrically distributed within the box frame 2. Each spiral stirring device 11 includes a stirring shaft, stirring blades, and a driving structure. The stirring blades of adjacent spiral stirring devices 11 on the same side rotate in opposite directions.

[0033] In a preferred embodiment, the box frame 2 is provided with side baffles 6. These baffles are used to accommodate the rear cold-mixed emulsified asphalt and to provide mounting support for other components.

[0034] In a preferred embodiment, the housing frame 2 is connected to its various components via fixing bolts 3, ensuring that they do not loosen or separate during operation.

[0035] In a preferred embodiment, the housing frame 2 is equipped with multiple connecting components 9, facilitating quick assembly and connection of the main unit for cold-mixed emulsified asphalt.

[0036] In a preferred embodiment, the box frame 2 is provided with multiple crossbars 14. The auxiliary rear paving box is connected to the central paving box 12.

[0037] In a preferred embodiment, the central paving box 12 is provided with multiple fasteners 13. These fasteners are used to connect to a tractor unit, providing a towing point when transporting or moving the paving box, and also connecting to the central paving box 12 as a whole.

[0038] In a preferred embodiment, the box frame 2 is symmetrically provided with side handles 4 on both sides. This provides a gripping position for construction workers during construction.

[0039] In a preferred embodiment, the box frame 2 is equipped with a traction adjustment rod 16, which is identical to the traction scraper system 17. This provides a traction point when transporting or moving the scraper system. For example, it connects to a tractor unit via this rod when construction is about to begin.

[0040] In a preferred embodiment, the scraping system 17 includes an adjusting frame 19 connected to the traction adjusting rod 16. The adjusting frame 19 is equipped with a scraper 18, and the scraper 18 has multiple sets of counterweight grooves 20. This system evenly scrapes the cold-mix emulsified asphalt material poured into the paving box, ensuring that the cold-mix emulsified asphalt is distributed on the construction road surface with the same thickness and density during paving operations, avoiding localized areas of excessive thickness or thinness. The counterweight can be adjusted via the counterweight grooves 20, allowing for fine control of the height, position, and angle of the scraper 18.

[0041] Example 2:

[0042] As shown in Figures 1 to 4, the slipper structure is made of copper alloy material, which has a certain degree of elasticity and wear resistance, and can make good contact with the road surface during the paving process to ensure the smoothness of the paving.

[0043] Example 3:

[0044] As shown in Figures 1 to 4, the central slipper 15 is located in the center. The central slipper 15 can balance the force on the left and right sides of the paving box, making the entire paving process more stable, reducing shaking and deviation. Together with the side slippers 1 on both sides, it bears the weight of the paving box and cold-mixed emulsified asphalt, reduces the load pressure on a single slipper, extends the service life of the slipper, and connects the central paving box 12.

[0045] Example 4:

[0046] As shown in Figure 4, the scraper 18 is made of 304 stainless steel or 316 stainless steel, which provides good corrosion resistance and can resist chemical corrosion. At the same time, the scraper 18 can be disassembled at any time.

[0047] Example 5:

[0048] As shown in Figures 1 to 4, the method of using this utility model is as follows:

[0049] Step 1: Survey the road to be repaired. Generally, ruts or potholes larger than 2cm need to be filled separately, and those larger than 3cm need to be milled.

[0050] Step 2: Inspect the integrity and performance of the paving box and its components to ensure there is no damage or malfunction;

[0051] Step 3: Clean the inside of the paving box to remove any remaining debris and dirt;

[0052] Step 4: Securely connect the paving box to the cold-mix emulsified asphalt and check the sealing of the connection.

[0053] Step 5: Prepare the required cold-mix emulsified asphalt and ensure that its quality and proportions meet the construction requirements;

[0054] Step 6: Start the power system of the cold-mix emulsified asphalt and the paving box, and check whether each component is operating normally;

[0055] Step 7: Adjust the height and angle of the scraper to achieve the required paving thickness;

[0056] Step 8: Calibrate the sensors and control system to ensure that they can accurately monitor and control construction parameters, such as paving speed and cold-mix emulsified asphalt flow rate;

[0057] Step 9: Pour the cold-mixed emulsified asphalt into the paving box, start the mixing device, and ensure that the materials are mixed evenly;

[0058] Step 10: Control the cold-mixed emulsified asphalt to move forward at an appropriate speed, and at the same time open the discharge port of the paving box to spread the cold-mixed emulsified asphalt evenly on the road surface.

[0059] Step 11: During the construction process, the operators closely observe the paving effect and adjust the scraper and discharge port in a timely manner to ensure the flatness and uniformity of the paving.

[0060] Step 12: Turn off the power system of the cold-mix emulsified asphalt and the paving box, clean the remaining cold-mix emulsified asphalt material inside the paving box to prevent solidification and blockage, and finally perform a thorough cleaning and maintenance of the paving box to prepare it for the next use.

[0061] The beneficial effects of this utility model are: it solves the problems of uneven paving, unstable quality after construction, and low efficiency; it can achieve fast and continuous paving operations by connecting a guide vehicle, thereby improving construction efficiency; and it can be quickly and flexibly adjusted according to different road conditions, engineering requirements, and material properties, making it widely adaptable.
