Abstract
Description
Technical Field
[0001] This utility model relates to the field of asphalt pavement structure technology, and in particular to a lightweight permeable asphalt pavement structure. Background Technology
[0002] Asphalt pavement refers to various types of road surfaces constructed by incorporating road-grade asphalt materials into mineral materials. Asphalt binders enhance the ability of paving aggregates to resist damage from traffic and natural factors, resulting in a smooth, dust-free, impermeable, and durable surface. Therefore, asphalt pavement is one of the most widely used high-grade pavements in road construction. While the asphalt structural layer itself falls under the category of flexible pavements, its base layer can also utilize rigid cement concrete or semi-rigid hydraulic materials in addition to flexible materials.
[0003] For example, Chinese Patent Application No. 202420034977.4 discloses a lightweight permeable asphalt pavement structure, belonging to the field of permeable asphalt pavement technology. It includes an asphalt pavement layer with water storage chambers installed on both sides. A drain pipe is installed at the lower side of each water storage chamber, and a cover plate is installed at the upper end of each chamber. The cover plate and the water storage chamber are fixedly connected by a cover plate fixing mechanism. A filter screen fixing mechanism is installed inside each water storage chamber. This invention, by setting up a cover plate fixing mechanism, facilitates the fixing of the cover plate, making it easier to clean the debris in the water storage chamber after opening the cover plate, thus preventing the debris from clogging the drain and hindering drainage. The filter screen fixing mechanism also prevents larger debris from falling to the bottom of the water storage chamber and facilitates the removal and cleaning of the filter screen, ensuring its effectiveness.
[0004] However, in the aforementioned asphalt pavement structure, the drainage pipes are difficult to position quickly during assembly, affecting assembly efficiency. Therefore, those skilled in the art have provided a lightweight permeable asphalt pavement structure to solve the problems mentioned in the background art. Utility Model Content

[0039] Reference Figures 1-4 The present invention provides a lightweight permeable asphalt pavement structure, including an asphalt pavement body 1, with drainage pipes 2 fixed on both sides of the asphalt pavement body 1, a filter metal plate 3 movably inserted into the top of the drainage pipe 2, multiple water filtering grooves 4 opened inside the filter metal plate 3, a locking mechanism 5 set on the outside of the drainage pipe 2, a stable closing mechanism 6 installed on the top of the drainage pipe 2, and a positioning mechanism 7 set on the outside of the drainage pipe 2.
[0040] The locking mechanism 5 includes a rust-proof threaded rod 51, one end of which is fixed with a limit plate 52, a washer 53 is movably sleeved on the outside of the rust-proof threaded rod 51, and a rust-proof threaded sleeve 54 is threadedly connected to the outside of the rust-proof threaded rod 51.
[0041] The positioning mechanism 7 includes a positioning movable plate 71, with a positioning groove 72 inside the positioning movable plate 71. An anti-detachment slider 73 is fixed to the outside of the positioning movable plate 71. A guide groove 75 is provided on one side of the drain pipe 2. A rust-proof metal handle 74 is fixed to the outside of the anti-detachment slider 73. The drain pipe 2 is slidably connected to the anti-detachment slider 73 through the guide groove 75. The size of the positioning groove 72 is adapted to the size of the rust-proof threaded rod 51. The outside of the rust-proof threaded sleeve 54 is provided with anti-slip texture to facilitate the user to rotate the rust-proof threaded sleeve 54, the rust-proof threaded rod 51, and the drain pipe 2. The water pipe 2 is fixedly connected. The inside of the gasket 53 is provided with a through hole that matches the size of the anti-rust threaded rod 51, so that the gasket 53 can move outside the anti-rust threaded rod 51. One side of the positioning movable plate 71 is attached to the outside of the drain pipe 2, and one side of the drain pipe 2 is connected to the asphalt pavement body 1. Water that seeps into the asphalt pavement body 1 can be discharged through the drain pipe 2. The outside of the anti-slip metal handle 74 is provided with anti-slip texture. The anti-rust metal handle 74 and the anti-detachment slider 73 are bonded and fixed to each other, which can ensure the stable connection between the anti-rust metal handle 74 and the anti-detachment slider 73.
[0042] The stable closing mechanism 6 includes a rust-proof metal shell 61. A support spring 62 is provided on one inner wall of the rust-proof metal shell 61. One end of the support spring 62 is connected to a movable plate 63. A positioning plate 64 is fixed on one side of the movable plate 63. A rust-proof metal column 66 is fixed on the outer side of the movable plate 63. A handle block 65 is fixed on the outer side of the movable plate 63. A groove is provided inside the filter metal plate 3. The size of the groove is adapted to the size of the positioning plate 64. When one end of the positioning plate 64 is movably inserted into the groove of the filter metal plate 3, the filter metal plate 3 can be locked. A through hole adapted to the size of the positioning plate 64 is provided inside the rust-proof metal shell 61. A guide groove is provided inside the rust-proof metal shell 61 to accommodate the movement of the handle block 65, so that the positioning plate 64 and the handle block 65 can move normally.
[0043] Working principle: When connecting adjacent drainage pipes 2, after the corresponding surfaces of the drainage pipes 2 are in contact, the rust-proof metal handle 74 can be moved. The rust-proof metal handle 74 drives the anti-disengagement slider 73 to slide within the guide groove 75, allowing the positioning movable plate 71 to be movably fitted onto the outside of the corresponding rust-proof threaded rod 51. Rotating the rust-proof threaded sleeve 54 clockwise allows the corresponding surface of the gasket 53 to be tightly pressed against the outside of the corresponding positioning movable plate 71, facilitating the connection and positioning between adjacent drainage pipes 2. This makes positioning and assembly easy. After assembly, when the asphalt pavement body 1 is in use, water is allowed to pass through the asphalt pavement. The asphalt permeable layer of the main body 1 enters the drainage pipe 2 for collection and diversion. After the filter metal plate 3 is installed on the top of the drainage pipe 2, the filter metal plate 3 can be used to block fallen leaves and garbage, reducing the amount of garbage entering the drainage pipe 2. After long-term use, the filter metal plate 3 needs to be opened to clean the inside of the drainage pipe 2. At this time, pull the handle block 65 horizontally to make the moving plate 63 drive one side of the positioning plate 64 to come out from the filter metal plate 3, which can easily complete the unlocking operation of the filter metal plate 3. After unlocking, the filter metal plate 3 on the top of the drainage pipe 2 can be opened, which facilitates the cleaning of the inside of the drainage pipe 2.
