Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1 and fig. 2, the present invention provides a technical solution:

the anti-skid wearing composite layer for the asphalt pavement comprises a pavement base layer 1, an adhesive layer 6 and an anti-skid wearing layer 7 arranged at the upper end of the adhesive layer 6, wherein a macadam base layer 2 is arranged at the upper end of the pavement base layer 1, a concrete layer 3 is arranged at the upper end of the macadam base layer 2, a cement asphalt mixing layer 4 is arranged at the upper end of the concrete layer 3, and a plurality of reinforcing components 5 matched with the adhesive layer 6 are uniformly distributed at the upper end of the cement asphalt mixing layer 4;

the reinforcing component 5 comprises a reinforcing barrel 501, a conical block 502 arranged at the lower end of the reinforcing barrel 501 and an annular fixing block 503 arranged outside the reinforcing barrel 501, a communicating cavity 504 is formed in the middle of the side wall of the reinforcing barrel 501, a plurality of air outlet cavities 505 are uniformly distributed in the middle of the annular fixing block 503, the air outlet cavities 505 respectively penetrate through the side wall of the reinforcing barrel 501 and are communicated with the inside of the communicating cavity 504, glue leakage openings 506 communicated with the inside of the communicating cavity 504 are formed in the bottom surface of the reinforcing barrel 501, a plurality of glue outlet openings 507 communicated with the inside of the communicating cavity 504 are uniformly distributed at the lower end of the side wall of the reinforcing barrel 501, two rectangular openings 508 communicated with the inside of the communicating cavity 504 are symmetrically formed in the side wall of the reinforcing barrel 501, two supporting rods 509 are symmetrically arranged on the side wall of the reinforcing barrel 501, a plurality of reinforcing rods 510 are symmetrically arranged in the middle of the two supporting rods 509, and one ends, far away from the supporting rods 510, are in a sharp-prick shape.

Further, the glue outlets 507 are all obliquely arranged, and one end with a high opening is communicated with the inside of the communicating cavity 504; in practical application, the structural adhesive flows out along the adhesive outlet 507 and is bonded with the cement asphalt mixing layer 4.

Further, an opening at the upper end of the reinforcing cylinder 501 is an arc-shaped concave surface; in practical applications, the structural adhesive is made to flow into the reinforcing cylinder 501 along the curved concave surface.

Further, the outer diameter of the conical block 502 is larger than that of the reinforcing cylinder 501, so that in practical application, a gap exists between the outer surface of the reinforcing cylinder 501 and the inner wall of the hole pressed by the conical block 502 for filling structural adhesive.

The working principle is as follows: when the structure glue injection device is used, firstly, a reinforcing cylinder 501 in a reinforcing component 5 is downwards hammered into the cement asphalt mixing layer 4, the reinforcing cylinder 501 moves downwards to enable a conical block 502 to move downwards, after a pointed part of a reinforcing rod 510 on the outer side of the reinforcing cylinder 501 is also inserted into the cement asphalt mixing layer 4, then a worker adds the structure glue from the middle part of the reinforcing cylinder 501, the structure glue flows downwards under the action of self gravity and flows into a communicating cavity 504 along a glue leakage opening 506, so that air in the communicating cavity 504 is extruded and discharged, the problem that the structure glue cannot freely fall down or air bubbles exist in the middle part of the structure glue due to air resistance in the adding process of the structure glue is avoided, then the structure glue sequentially flows into a groove drilled at the upper end of the cement asphalt mixing layer 4 along a glue outlet 507, so that the structure glue is contacted with the cement asphalt mixing layer 4, and then the structure glue can spread to the upper surface of the cement asphalt mixing layer 4, the structure is glued and is spread can make bracing piece 509 and reinforced bar 510 to be flooded gradually, improves and consolidates the effect, when the structure is glued and is spread and flood a reinforcement section of thick bamboo 501 up end, the staff continues to add the structure and glues for the structure is glued and is higher than a reinforcement section of thick bamboo 501 up end, then trowels, is convenient for lay anti-skidding wearing layer 7.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
