[0002] An asphalt pavement permeability meter is a specialized device used to measure the permeability of asphalt pavements. It is primarily used to assess the drainage capacity of roads, ensuring that asphalt pavements can effectively drain water in rainy or wet conditions, thereby improving driving safety and extending the service life of the road. The asphalt pavement permeability meter mainly consists of a permeability ring, measuring equipment, a counterweight, and water. By placing the permeability ring on the asphalt pavement and ensuring its seal, a certain amount of water is injected into the ring, and timing begins, recording the drop in water level to calculate the water permeability.

[0003] Before conducting water seepage tests, the asphalt pavement needs to be cleaned to prevent debris from affecting the test results. Usually, staff members have to take out brooms to clean the pavement, which is time-consuming and laborious, greatly affecting the efficiency of the tests. Utility Model Content

[0021] like Figures 1 to 6 The aforementioned water permeability testing device for asphalt pavement construction includes a mobile frame 1, with a push handle 21 fixedly connected to one end of the mobile frame 1. The mobile frame 1 has four wheels 22 at its bottom corners. A lifting bracket is mounted on the mobile frame 1, and an asphalt pavement water permeability meter is fixedly connected to the lifting bracket. The asphalt pavement water permeability meter includes a testing base 3. A drain pipe 6 and a fixing frame 4 are fixedly connected to the upper end of the testing base 3. A measuring cylinder 5 communicating with the drain pipe 6 is fixedly connected to the fixing frame 4. A switch valve is provided on one side of the drain pipe 6. A testing groove communicating with the drain pipe 6 is provided at the lower end of the testing base 3. An exhaust valve communicating with the testing groove is provided on the testing base 3. A testing hole 2 cooperating with the asphalt pavement water permeability meter is provided on the mobile frame 1. The lifting bracket includes support frames 8 fixedly connected to both sides of the testing hole 2. Fixing plates are fixedly connected to both sides of the fixing frame 4. A lifting cylinder 7 is fixedly connected between the support frame 8 and the fixing plates.

[0022] A jet pipe 11 is rotatably connected to the mobile frame 1. A cleaning arm 15 is fixedly connected to one end of the jet pipe 11 extending to the bottom surface of the mobile frame 1. A cleaning brush 17 is fixedly connected to the bottom surface of the cleaning arm 15. A cavity communicating with the jet pipe 11 is provided inside the cleaning arm 15. Cleaning nozzles 16 communicating with the cavity are provided on both sides of the cleaning arm 15. A jet pump 9 is fixedly connected to the mobile frame 1. An output pipe 10 is fixedly connected to the output end of the jet pump 9. The output pipe 10 is rotatably connected to the jet pipe 11. A reciprocating swing mechanism for driving the jet pipe 11 to rotate is provided on the mobile frame 1.

[0023] The reciprocating swing mechanism includes a driven incomplete gear 12 fixedly sleeved on the outer wall of the jet pipe 11, an active incomplete gear 13 rotatably connected to the bottom surface of the mobile frame 1 and meshing with the driven incomplete gear 12, a motor 14 fixedly connected to the mobile frame 1 to drive the active incomplete gear 13 to rotate, a return spring 18 that cooperates with the driven incomplete gear 12 on the mobile frame 1, a return slider 19 fixedly connected to the upper end of the driven incomplete gear 12, an arc-shaped groove 20 on the bottom surface of the mobile frame 1 that cooperates with the movement trajectory of the return slider 19, and the return spring 18 is arc-shaped and fixedly connected to one end of the return slider 19 and the arc-shaped groove 20.

[0024] In practical use, the mobile frame 1 is pushed to move the asphalt pavement permeability meter to the required testing point.
