A vertical plate 303 is rotatably sleeved on the shaft of one of the rotating shafts 302, and a semicircular seat 304 is fixedly sleeved on the shaft of the other rotating shaft 302. A rotating seat 305 is rotatably installed on one side of the bottom surface of the semicircular seat 304, and an arc-shaped toothed plate 306 is fixedly embedded on the other side of the bottom surface of the semicircular seat 304. The top surface of the mounting frame 301 A placement box 307 is fixedly installed on the top, and a downpipe 308 is fixedly installed in the middle of the bottom surface of the placement box 307. In this embodiment, the water injection component 4 includes a water supply box 401, and a nozzle 402 is fixedly installed at the center of the bottom surface of the water supply box 401. Water is sprayed to the upper surface of the road surface sample through the nozzle 402, and the water penetrates the road surface sample and falls from the bottom of the road surface sample. Since the bottom surface of the placement box 307 is conical, the penetrated water will enter the downpipe 308;

[0033] The vertical plate 303 and the rotating seat 305 are respectively fixedly mounted on the two side edges of the top surface of the bottom frame 101 .

[0034] The water supply box 401 is fixedly mounted on the top surface of the top plate 103 , and the nozzle 402 is located directly above the placement box 307 .

[0035] The two vertical plates 201 are respectively fixedly mounted on the front and rear edges of one side of the top surface of the bottom frame 101 , and one end of the output shaft of the driving motor 204 is fixedly connected to one end of the screw rod 202 .

[0036] The bottom surface of the long tooth plate 203 is in contact with the top surface of the bottom frame 101, and the long tooth plate 203 is meshed with the arc-shaped tooth plate 306. The screw 202 can drive the long tooth plate 203 to move by rotating, and the arc-shaped tooth plate 306 can be rotated by the movement of the long tooth plate 203, and the semicircular seat 304 can be rotated by the rotation of the arc-shaped tooth plate 306.

[0037] The outer thread of the down pipe 308 is connected to a No. 1 threaded pipe 309, and the outer thread of the No. 1 threaded pipe 309 is connected to a No. 2 threaded pipe 310.

The water passes through the downpipe 308 and falls into the water collecting box 104. The water that passes through the pavement sample is stored in the water collecting box 104. After the water spraying time is preset, the water spraying is stopped, and the water that passes through the pavement sample stored in the water collecting box 104 is weighed, thereby completing the water permeability test of the pavement sample.

[0039] Working principle: When conducting sample testing, the pavement sample is taken out and placed in the placement box 307. After the sample is placed, water is sprayed on the upper surface of the pavement sample through the nozzle 402. The water penetrates the pavement sample and falls from the bottom of the pavement sample. Since the bottom surface of the placement box 307 is conical, the penetrated water will enter the downpipe 308, pass through the downpipe 308 and fall into the water collecting box 104. The water that penetrates the pavement sample is stored in the water collecting box 104. After the preset water spraying time, the water spraying is stopped, and the water that penetrates the pavement sample stored in the water collecting box 104 is weighed, thereby completing the water permeability test of the pavement sample. At the same time, when it is necessary to detect the permeability of the pavement sample on a slope, The water property can be detected by starting the driving motor 204, which drives the screw 202 to rotate. The rotation of the screw 202 can drive the long tooth plate 203 to move. The movement of the long tooth plate 203 can drive the arc tooth plate 306 to rotate. The rotation of the arc tooth plate 306 can drive the semicircular seat 304 to rotate. The rotation of the semicircular seat 304 can cause the installation frame plate 301 to rotate. The rotation of the installation frame plate 301 can drive the placement box 307 to rotate. The rotation of the placement box 307 can drive the road surface sample placed therein to rotate, so that road surfaces with different slopes can be simulated as needed, and then the above-mentioned detection steps can be repeated to detect the water permeability of the road surface sample under the slope state.

[0040] When further testing is required on the spot, the device can be moved to the detection position, and then the No. 2 threaded tube 310 and the No. 1 threaded tube 309 can be manually rotated so that the bottom end of the No. 2 threaded tube 310 is in contact with the bottom surface, and then the joint between the No. 2 threaded tube 310 and the road surface is sealed by spraying foam glue through a spray bottle. After sealing, a certain amount of water is poured into the placement box 307, and the permeability of the road surface is detected by recording the time it takes for water to completely penetrate from the device into the road surface, which is more practical.
