Description

Technical Field

[0001] The utility model relates to the technical field of grouting material surface treatment, in particular to a pouring type semi-flexible pavement grouting material solidification surface treatment device. Background Art

[0002] In the construction of semi-flexible pavement, the asphalt mixture is first laid on the roadbed and rolled repeatedly for a long time using a roller to reduce the pores in the asphalt mixture. Then, a high-fluidity cement-based grouting material is manufactured using grouting equipment and output to flow on the surface and inside of the asphalt mixture, thereby filling the pores formed by the asphalt mixture and forming a composite pavement material that is both rigid and flexible.

[0003] As mentioned above, the prepared cement-based grouting material fills the pores of the asphalt roadbed. At the same time, in order to make the road surface smooth, the staff is required to push the leveling equipment back and forth on the asphalt roadbed to promote the circulation of the cement-based grouting material to prevent it from accumulating in one place and solidifying to form an uneven road surface.

[0004] Although the scraping treatment method can reduce the probability of cement-based grouting material accumulation and solidification, the manual operation of the scraping equipment is not very rigorous, and some cement-based grouting materials will always accumulate and solidify. After the cement-based grouting material solidifies, the entire road surface has poor flatness. In order to improve the flatness of the road surface, a secondary treatment is required, that is, to remove the protruding parts of the road surface.

[0005] Although there are special road surface treatment equipment on the market, such as a Chinese patent with the publication number CN215925573U that discloses a poured semi-flexible road grouting material solidification surface treatment device, the purchase of the above equipment increases the construction cost. If the scraper can be improved, the construction cost can be reduced while improving the road leveling efficiency. Utility Model Content

The support 2 is provided with two symmetrical sets, and the upper ends of the two sets of supports 2 can be adjusted to be sleeved on the push handle 12, and the scraping plate 21 is fixedly arranged below the two sets of supports 2. The first support adjustment mechanism 5 and the second support adjustment mechanism 6 are respectively adjusted and arranged at the two ends of the scraping plate 21, and one of the support adjustment mechanisms is connected to the motor. In addition, the annular belt 3 is sleeved on the first support adjustment mechanism 5 and the second support adjustment mechanism 6, and the scraping plate 21 is arranged through the annular belt 3, and a sawtooth 31 is arranged at the lower end of the outer side of the annular belt 3, and the sawtooth 31 is evenly distributed along the circumference direction of the annular belt 3, and the lower side of the sawtooth 31 is flush with the lower side of the annular belt 3. When pouring the semi-flexible pavement, by adjusting the state of the support 2 relative to the push handle 12, the scraping plate 21 is lowered and in contact with the asphalt pavement, and the staff pushes the device to move. Under the push of the scraping plate 21, the cement-based grouting material is laid on the asphalt pavement on a large scale. After the cement-based grouting material solidifies, if it is found that the flatness of the semi-flexible pavement is poor, the staff can adjust the state of the support adjustment mechanism relative to the scraping plate 21, control the annular belt 3 to descend, and make the lower end of the annular belt 3 flush with the lower end surface of the scraping plate 21. Then, the generator 11 provides electrical energy to the motor, and the motor drives the support adjustment mechanism to rotate, thereby controlling the annular belt 3 and the sawtooth 31 to rotate synchronously at high speed, and at the same time pushing the device to move, efficiently removing protruding materials, and correspondingly improving the flatness of the semi-flexible pavement, as well as the leveling and finishing efficiency. In addition, the device is only an annular belt 3 added on the basis of the existing scraping machine, with a simple structure and low cost.
