Description

Technical Field

[0001] This utility model relates to the field of road surface testing technology, specifically to an asphalt pavement water seepage detection device. Background Technology

[0002] Because asphalt pavement structures are subjected to far more severe water erosion than the pavement surface, the water pressure generated by surface water under the tires of high-speed vehicles can directly penetrate the asphalt surface layer. To minimize water damage to the pavement structure layers, the interlayer bonding materials of asphalt pavements must not only possess high water tightness but also a certain degree of resistance to water loss. Currently, in road construction, a pavement permeability meter is commonly used to measure the amount of water that permeates into a certain area of ​​the pavement per unit time. This permeability coefficient is used to evaluate the pavement's permeability performance, reflecting factors such as the gradation composition of the asphalt mixture. Permeability rate has become an important indicator for evaluating pavement performance.

[0003] Chinese Patent CN220603256U discloses an asphalt pavement water seepage detection device, including a fixed base. A motor is fixedly connected to the top of the fixed base, and a transmission shaft is fixedly connected to the output end of the motor. A gear is fixedly connected to the top of the transmission shaft. When the motor is started, it drives the transmission shaft to rotate, which in turn drives the gear to rotate the gear plate. The rotation of the gear plate causes the first and second movable rings to rotate in a circle around the fixed base. The rotation of the first and second movable rings causes the first fixed plate to rotate synchronously, which in turn causes the waterproof adhesive to rotate. After the waterproof adhesive rotates, the adhesive liquid inside can be evenly spread around the base ring. At the same time, the rotation of the first fixed plate drives the connecting rod to rotate, which in turn drives the scraper to rotate. The rotation of the scraper allows the adhesive liquid at the bottom to be evenly scraped away, thereby improving the sealing of the base ring.

[0004] However, the above technical solution has the following shortcomings: on the one hand, it requires a motor and a miniature cylinder to independently realize the two actions of rotating the waterproof adhesive around the edge of the fixed seat and applying the adhesive; on the other hand, it is necessary to ensure that the miniature cylinder and the motor move synchronously to ensure the uniformity of the adhesive application, which not only results in high production costs but also poor practicality.

[0017] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0018] This invention utilizes a coordinated arrangement of a drive mechanism, a transmission mechanism, and a glue-applying mechanism.

This not only reduces the use of power components and lowers production costs but also ensures the synchronization of the glue-applying head rotation and glue application, improving the uniformity of glue application.
