Description

Technical Field

[0001] This utility model relates to the field of measuring instruments, specifically to a road surface water permeability measuring instrument. Background Technology

[0002] With the acceleration of urbanization, road construction, as a crucial component of infrastructure development, directly impacts traffic safety and road lifespan. Road surface permeability is a vital indicator of road quality; good permeability effectively reduces water accumulation on the road surface, improves driving safety, and extends the road's lifespan. Therefore, conducting permeability testing after road construction is essential.

[0003] However, currently available pavement permeability measuring instruments have certain limitations in practical applications. Specifically, newly paved or repaired pavement surfaces often have issues such as dust, fine particles, and incompletely filled potholes. When using traditional permeability measuring instruments, these surface defects make it difficult to form a tight contact and effective seal between the instrument's base and the pavement. Due to the poor sealing, moisture inside the measuring cylinder may leak out through these gaps, interfering with the normal permeability measurement process and leading to errors in the measurement.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a road surface water permeability measuring instrument to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A pavement permeability measuring instrument includes a measuring base, a sealing groove on the top of the measuring base, a measuring cylinder slidably installed inside the sealing groove, a sealing gasket fixedly connected to the bottom surface of the measuring base, a bearing ring fixedly connected to the top of the measuring base, a fan fixedly installed on the surface of the bearing ring, an exhaust pipe fixedly connected to the air outlet of the fan, a connecting sleeve fixedly installed at the end of the exhaust pipe, a heating channel inside the measuring base, a heat-conducting plate fixedly connected to one side of the heating channel and fixedly connected to the sealing gasket, an air inlet pipe fixedly installed on one side of the heating channel and an exhaust port at the other end, the air inlet pipe cooperating with the connecting sleeve.

[0008] Furthermore, in order to enable the measuring device to move and be supported, a positioning plate is fixedly connected to the surface of the measuring base, and an adjusting bolt is threadedly connected to one side of the surface of the positioning plate. A caster wheel is rotatably installed at the end of the adjusting bolt.

[0009] Furthermore, in order to improve the sealing performance between the gasket and the road surface measuring point, the gasket is made of thermoplastic vulcanized rubber.

[0010] Furthermore, to facilitate applying load to the measuring base by pressing, pressing handles are fixedly installed on both sides of the surface of the bearing ring.

[0011] Furthermore, to facilitate the observation of the amount of water seepage inside the graduated cylinder, a sliding groove is provided on the inner wall of the graduated cylinder, and a floating block is slidably installed inside the sliding groove.

[0012] Furthermore, in order to accurately monitor the seepage time, a timer is fixedly installed on one side of the surface of the bearing ring.

[0013] Furthermore, in order to provide power to the fan and timer, a power interface is provided on one side of the surface of the bearing ring.

[0014] The beneficial effects of this utility model are as follows: Before measurement, the blower can clean the water seepage measurement points on the road surface by blowing air, efficiently dispersing and cleaning dust and other impurities at the measurement points, improving the sealing performance when the sealing gasket contacts the road surface at the measurement point. Furthermore, the blower blows hot air into the heating channel inside the measurement base, causing the thermoplastic sealing gasket to soften. After pressing the measurement base, the softened sealing gasket can fill the gaps and small potholes on the ground, further improving the sealing performance when the sealing gasket contacts the road surface at the measurement point. This effectively improves the measurement accuracy and effect of road surface water seepage measurement, ensuring the accuracy of water seepage measurement. Attached Figure Description

A sealing groove 2 is formed at the top of the measuring base 1, and a measuring cylinder 3 is slidably installed inside the sealing groove 2 for measuring pavement permeability. A sealing gasket 4, made of thermoplastic vulcanized rubber, is fixedly connected to the bottom surface of the measuring base 1 for sealing contact with the pavement at the measurement point. A bearing ring 5 is fixedly connected to the top of the measuring base 1, and a fan 6 is fixedly installed on the surface of the bearing ring 5. This fan 6 is a hot and cold air fan capable of blowing hot air and room temperature air. An exhaust pipe 7 is fixedly connected to the air outlet of the fan 6, and a connecting... The heating channel 9 is opened inside the measuring base 1. A heat-conducting plate 10 is fixedly connected to one side of the heating channel 9. The heat-conducting plate 10 is a copper ring and is fixedly connected to the sealing gasket 4. An air inlet pipe 11 is fixedly installed on one side of the heating channel 9 and an air outlet 12 is opened at the other end. The air inlet pipe 11 cooperates with the connecting sleeve 8. The air outlet pipe 7 is connected to the air inlet pipe 11 through the connecting sleeve 8. After the fan 6 is started, hot air is blown into the heating channel 9 and discharged through the exhaust port 12, so that the heat-conducting plate 10 transfers heat to the sealing gasket 4, so that the sealing gasket 4 softens after being heated, thereby increasing the sealing performance when the sealing gasket 4 is pressed and in contact with the road surface.

[0027] like Figures 1-5 As shown, a positioning plate 13 is fixedly connected to the surface of the measuring base 1. An adjusting bolt 14 is threadedly connected to one side of the surface of the positioning plate 13. A universal wheel 15 is rotatably installed at the end of the adjusting bolt 14. By turning the adjusting bolt 14, the universal wheel 15 can be raised and lowered, allowing the universal wheel 15 to move and support the entire measuring instrument after the measurement is completed, facilitating the movement of the entire measuring instrument and leveling it. Press handles 16 are fixedly installed on both sides of the surface of the bearing ring 5, which can be used to press and load the measuring base 1 and the sealing gasket 4, increasing the sealing performance between the sealing gasket 4 and the measuring point. A sliding groove 17 is opened on the inner wall of the measuring cylinder 3. A float block 18 is slidably installed inside the sliding groove 17. The float block 18 moves with the liquid level in the measuring cylinder 3, which can facilitate the observation of the seepage amount during the measurement. A timer 19 is fixedly installed on one side of the surface of the bearing ring 5, which can facilitate the accurate monitoring of the seepage time at the measuring point. A power interface 20 is opened on one side of the surface of the bearing ring 5, which is used to facilitate the power connection of the fan 6 and the timer 19.

[0028] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0029] In summary, with the help of the above-mentioned technical solution of this utility model, in actual use, by starting the fan 6, aligning the connecting sleeve 8 at the end of the exhaust pipe 7 with the bottom of the measuring base 1, the exhaust air blows on the road surface measuring area, effectively blowing away and cleaning the dust and other impurities at the measuring area, improving the sealing performance of the sealing gasket 4 when it comes into contact with the road surface at the measuring area; after cleaning, the sealing gasket 4 is placed at the measuring area, and the connecting sleeve 8 at the end of the exhaust pipe 7 is installed on the air inlet pipe 11 on one side of the measuring base 1. The fan 6 is started and blows out hot air, which enters the heating channel 9. The heat of the hot air is transferred to the sealing gasket 4 through the heat-conducting plate 10 at the bottom of the heating channel 9. The thermoplastic sealing gasket 4 softens after being heated. By pressing the measuring base 1 down with the handle 16, the softened sealing gasket 4 is subjected to pressure and makes full contact with the measuring area, improving the sealing performance during the measurement. During the measurement, a certain amount of water is injected into the measuring cylinder 3, and a seepage time is set by the timer 19, so as to observe the change in the amount of water seepage in the measuring cylinder 3.
