Description

Technical Field

[0001] This utility model relates to the technical field of asphalt pavement permeability meters, and in particular to a pavement permeability meter. Background Technology

[0002] An asphalt pavement permeability meter is an instrument used to determine the permeability coefficient of asphalt mixture pavements and compacted asphalt mixture specimens. The permeability rate reflects the water permeability performance of the asphalt pavement. When using a permeability meter, a waterproof material needs to be applied around it, and a counterweight should be used to seal the meter.

[0003] A search revealed a Chinese patent application with patent number CN202421573928.4, which discloses a road seepage meter. This device has a marking ring on the base of a traditional road seepage meter, allowing for direct manual marking, which is convenient to use, more accurate, and less prone to loss. However, the above technical solution still requires manual opening and closing of the exhaust valve and the control valve on the outer wall of the connecting pipe according to the detection steps, thus resulting in low efficiency in road seepage detection. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a road surface permeability meter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A road surface permeability meter includes a base, with multiple columns fixed to the top outer wall of the base, a top plate fixed to the top outer wall of each column, a water-holding cylinder inserted into the inner wall of the top plate, a connecting pipe inserted into the bottom end of the water-holding cylinder, the connecting pipe passing through the bottom outer wall of the base, a first electrically controlled valve installed on the outer wall of the connecting pipe, a water collection frame fixed to the top outer wall of the base, an exhaust pipe inserted into the bottom inner wall of the water collection frame, a second electrically controlled valve installed on the outer wall of the exhaust pipe, and an immersion probe installed on one side inner wall of the water collection frame.

[0006] As a further embodiment of this utility model: a support plate and a water immersion sensor are fixed to the outer wall of the top plate, a control panel is fixed to the outer wall of the support plate, the water immersion sensor is connected to the water immersion probe through a signal transmission line, and the water immersion sensor is connected to the control panel through a signal transmission line.

[0007] As a further improvement of this utility model, a counterweight is inserted into the outer wall of the base and the column.

[0008] As a further embodiment of this utility model: a water pump is fixed to the outer wall of the support plate, a drain pipe is inserted into the output end of the water pump, and the water pump is electrically connected to the control panel.

[0009] As a further embodiment of this utility model: a first mounting bracket and a second mounting bracket are respectively fixed on the outer walls of both sides of the support plate. A first infrared transmitter is provided on the outer wall of the opposite side of the first mounting bracket, and a second infrared transmitter is provided on the outer wall of the opposite side of the second mounting bracket.

[0010] As a further improvement of this utility model: a buoyancy block is provided on the inner wall of the water-holding cylinder, and the diameter of the buoyancy block is smaller than the inner diameter of the water-holding cylinder.

[0011] As a further improvement of this utility model: a warning light is fixed to the outer wall of the support plate, and the warning light is electrically connected to the control panel.

[0012] As a further improvement of this utility model, a power supply box is fixed to the outer wall of the top of the top plate.

[0013] The beneficial effects of this utility model are as follows: 1. This utility model allows workers to automatically complete the venting, water filling, and control of the opening and closing of the corresponding connecting pipes and venting pipes simply by installing and sealing the base on the corresponding test surface. Workers can calculate the accurate pavement permeability coefficient based on the countdown time displayed on the control panel and the remaining water level in the measuring cylinder. There is no need for workers to manually open and close the connecting pipes and venting pipes according to the test procedure, or to add water to the measuring cylinder multiple times. This allows for quick and accurate measurement of the pavement permeability coefficient, improving the efficiency of pavement permeability measurement.

[0014] 2. The second infrared transmitter corresponds to the 500ml area inside the water measuring cylinder, and the first infrared transmitter corresponds to the 100ml area inside the water measuring cylinder. When the water level inside the water measuring cylinder reaches 500ml, the buoyancy block located inside the water measuring cylinder will float to the side of the second infrared transmitter, blocking the light emitted by the second infrared transmitter. At this time, the control panel will control the water pump to turn off, allowing the water pump to automatically pump 500ml of water into the water measuring cylinder.

[0015] 3. When the control panel stops timing and closes the first electrically controlled valve, the control panel will light up to indicate the end of the inspection and allow staff to calculate the road permeability coefficient based on the timing and the water level data inside the measuring cylinder.

Detailed Implementation

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0020] Example 1: A road surface permeability meter, such as Figure 1-6 As shown, the system includes a base 1, with multiple columns 15 fixed to the top outer wall of the base 1, a top plate 4 fixed to the top outer wall of the columns 15, a water measuring cylinder 10 inserted into the inner wall of the top plate 4, a connecting pipe 17 inserted into the bottom end of the water measuring cylinder 10, the connecting pipe 17 passing through the bottom outer wall of the base 1, a first electrically controlled valve 16 provided on the outer wall of the connecting pipe 17, a water collecting frame 18 fixed to the top outer wall of the base 1, an exhaust pipe 21 inserted into the bottom inner wall of the water collecting frame 18, a second electrically controlled valve 20 provided on the outer wall of the exhaust pipe 21, and a water immersion probe 19 provided on one side inner wall of the water collecting frame 18. The top outer wall of the top plate 4 is fixed with a support plate 11 and a water immersion sensor 3. The outer wall of the support plate 11 is fixed with a control panel 13. The water immersion sensor 3 is connected to the water immersion probe 19 through a signal transmission line. The water immersion sensor 3 is also connected to the control panel 13 through a signal transmission line. The base 1 and the column 15 are fitted with counterweights 2 on their outer walls; A water pump 9 is fixed to the outer wall of the support plate 11. A drain pipe 8 is inserted into the output end of the water pump 9. The water pump 9 is electrically connected to the control panel 13. First, following the steps given in T0971-2019 Test Method for Permeability Coefficient of Asphalt Pavement in Highway Subgrade and Pavement Field Testing Procedure JTG3450-2019, after sealing and fixing the base 1 at the corresponding test position on the pavement, the input end of the water pump 9 can be connected to the water outlet device such as the water storage tank through the pipeline. Then, the control panel 13 controls the operation of the water pump 9, and pumps water into the water measuring cylinder 10 through the drain pipe 8. After pumping 500ml of water into the water measuring cylinder 10, the control panel 13 controls the water pump 9 to turn off, and then controls the first electric control valve 16 to open, injecting water into the base 1 through the connecting pipe 17, thereby venting the gas inside the base 1 to the outside through the exhaust pipe 21. After the gas inside the base 1 is exhausted, the water that has been filled into the base 1 will flow into the water collection frame 18 through the exhaust pipe 21. At this time, the immersion sensor 3 will detect the water flowing into the water collection frame 18 through the immersion probe 19 on the inner wall of the water collection frame 18. This allows the control panel 13 to control the second solenoid valve 20 and the first solenoid valve 16 to close in time. Then, the control panel 13 controls the water pump 9 to start running again and replenish the water volume cylinder 10 with water until the water volume cylinder 10 is filled with 500ml of water again. Then, the control panel 13 will control the water pump 9 to close. Then, the control panel 13 will control the first solenoid valve 16 to open again, and the timing mechanism inside the control panel 13 will start a three-minute countdown. When the water level inside the measuring cylinder 10 drops by 400ml, even if it has not exceeded three minutes, the control panel 13 will control the first solenoid valve 16 to close, and at the same time end the timing and display the time on the screen. When three minutes have passed and the water level inside the measuring cylinder 10 has not dropped by 400ml, the control panel 13 will control the first electric valve 16 to close. Then, the staff can calculate the road seepage coefficient based on the actual water level inside the measuring cylinder 10. This invention allows workers to automatically vent air, add water, and control the opening and closing of the corresponding connecting pipe 17 and vent pipe 21 simply by installing and sealing the base 1 on the corresponding test surface. Workers can calculate the accurate pavement permeability coefficient based on the countdown time displayed on the control panel 13 and the remaining water level inside the measuring cylinder 10. This eliminates the need for workers to manually open and close the connecting pipe 17 and vent pipe 21 according to the testing procedure, or to add water to the measuring cylinder 10 multiple times. This allows for quick and accurate measurement of the pavement permeability coefficient, improving the efficiency of pavement permeability measurement.

[0021] like Figure 1-5 As shown, a first mounting bracket 12 and a second mounting bracket 6 are respectively fixed on the outer walls of both sides of the support plate 11. A first infrared transmitter 5 is provided on the outer wall opposite to the first mounting bracket 12, and a second infrared transmitter 7 is provided on the outer wall opposite to the second mounting bracket 6. The inner wall of the water measuring cylinder 10 is provided with a buoyancy block 22, the diameter of which is smaller than the inner diameter of the water measuring cylinder 10.

[0022] The second infrared transmitter 7 corresponds to the 500ml area inside the water measuring cylinder 10, and the first infrared transmitter 5 corresponds to the 100ml area inside the water measuring cylinder 10. When the water level inside the water measuring cylinder 10 reaches 500ml, the buoyancy block 22 located inside the water measuring cylinder 10 will float to the side of the second infrared transmitter 7, blocking the light emitted by the second infrared transmitter 7. At this time, the control panel 13 will control the water pump 9 to turn off, so that the water pump 9 can automatically pump 500ml of water into the water measuring cylinder 10. When the water level inside the measuring cylinder 10 drops by 400ml, the buoyancy block 22 located on the inner wall of the measuring cylinder 10 will float on one side of the first infrared transmitter 5, blocking the light emitted by the second infrared transmitter 7. At this time, the control panel 13 will control the first electric valve 16 to close and stop the timing, indicating that 400ml of water has been discharged from the measuring cylinder 10. like Figure 1 As shown, a warning light 23 is fixed to the outer wall of the support plate 11. The warning light 23 is electrically connected to the control panel 13. When the control panel 13 ends the timing and controls the first electric valve 16 to close, it will simultaneously control the warning light 23 to light up, indicating to the staff that the inspection is over and allowing the staff to calculate the road permeability coefficient in a timely manner based on the timing and the water level data inside the water-filled measuring cylinder 10.

[0023] like Figure 1 As shown, a power supply box 14 is fixed to the outer wall of the top plate 4; the outer wall of the power supply box 14 is provided with an AC power interface, so that the road surface infiltration meter can be powered by AC power. At the same time, a storage battery can be installed inside the power supply box 14 to power the road surface infiltration meter.

[0024] In this embodiment, the timing mechanism inside the control panel 13 can be a microcontroller timer or other timing device. The second infrared transmitter 7 and the first infrared transmitter 5 are both commercially available infrared transmitter devices. The immersion sensor 3 and the immersion probe 19 are both commercially available immersion sensors. Therefore, the specific working principle of the above devices will not be elaborated here.

[0025] Working principle: After the base 1 is sealed and fixed at the corresponding detection position on the road surface, the input end of the water pump 9 can be connected to the water outlet device such as the water storage tank through the pipeline. Then, the control panel 13 controls the operation of the water pump 9, and the water is pumped into the water measuring cylinder 10 through the drain pipe 8. After 500ml of water is pumped into the water measuring cylinder 10, the control panel 13 controls the water pump 9 to turn off, and then controls the first electric control valve 16 to open, injecting water into the base 1 through the connecting pipe 17, thereby venting the gas inside the base 1 to the outside through the exhaust pipe 21. After the gas inside the base 1 is exhausted, the water that has been filled into the base 1 will flow into the water collection frame 18 through the exhaust pipe 21. At this time, the immersion sensor 3 will detect the water flowing into the water collection frame 18 through the immersion probe 19 on the inner wall of the water collection frame 18. This allows the control panel 13 to control the second solenoid valve 20 and the first solenoid valve 16 to close in time. Then, the control panel 13 controls the water pump 9 to start running again and replenish the water volume cylinder 10 with water until the water volume cylinder 10 is filled with 500ml of water again. Then, the control panel 13 will control the water pump 9 to close. Then, the control panel 13 will control the first solenoid valve 16 to open again, and the timing mechanism inside the control panel 13 will start a three-minute countdown. When the water level inside the measuring cylinder 10 drops by 400ml, even if it has not exceeded three minutes, the control panel 13 will control the first solenoid valve 16 to close, and at the same time end the timing and display the time on the screen. If the water level inside the measuring cylinder 10 does not drop by 400ml after three minutes, the control panel 13 will control the first electric valve 16 to close. Then, the staff can calculate the road seepage coefficient based on the actual water level inside the measuring cylinder 10.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
