Description

Technical Field

[0001] This invention belongs to the technical field of highway testing equipment, specifically relating to a ground permeability testing device for highway maintenance. Background Technology

[0002] In highway maintenance, pavement permeability is a crucial indicator. Poor permeability can easily lead to water accumulation on the road surface, increasing the risk of vehicle skidding and loss of control, thus affecting driving safety. Therefore, inspectors typically use existing permeability testing devices to periodically test pavement permeability. However, in existing permeability testing devices, the upper end of the measuring cylinder is usually directly exposed to the air. As the water level inside the measuring cylinder decreases, the water pressure inside the cylinder also gradually decreases, making it impossible to ensure that the water pressure inside the measuring cylinder remains constant. This can easily reduce the accuracy of pavement permeability test results. Furthermore, most existing pavement permeability testing devices can only measure the rate of water infiltration and cannot simulate the permeability of the pavement under dynamic water pressure (such as when a car is driving on the road), reducing the reliability of pavement permeability test results. Therefore, there is an urgent need to design a pavement permeability testing device for highway maintenance to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a road surface permeability testing device, including: a water outlet component, a sealing component, a base, and two counterweight plates. The sealing component uses sealing mud. During the water permeability testing process, the sealing mud placed between the road surface and the device can fill the gap between the device and the road surface, preventing water inside the device from leaking into the surrounding area of ​​the testing device through the gap. The sealing mud effectively ensures the stability of the testing environment and the accuracy of the testing results. At the same time, when this device tests the permeability of different testing points, the sealing mud needs to be replaced each time, which can further ensure the sealing effect of the sealing mud on the gaps between the device and the road surface.

[0004] The water outlet assembly includes: a valve body, a valve core, a water pressure sensor, a controller, a main detector, and an auxiliary detector. The valve body has an inlet and an outlet. The valve core is rotatably mounted on the valve body, meaning it can rotate relative to the valve body, and during rotation, it regulates the water flow between the inlet and outlet. A corresponding drive structure can be configured to drive the valve core, thereby achieving active control of the water flow. The controller controls the valve core rotation based on the water pressure sensor's detection value. The controller can be connected to a power source, such as a drive motor, to control the valve core's rotation relative to the valve body. Specifically, after the water pressure sensor detects the water pressure at the outlet, it outputs the pressure value to the control module. The control module analyzes and calculates the water pressure value, and when the water pressure value differs from the target pressure value, it converts the pressure difference into a rotation angle. The control module then sends the obtained rotation angle to the controller, which controls the corresponding drive structure to drive the valve core by the corresponding rotation angle. When the water pressure is the same as the target value, there is no need to drive the valve core to rotate. When the water pressure is less than or greater than the target value, the valve core can be driven to rotate in the forward or reverse direction, so that the adjusted water pressure meets the water supply requirements. The water pressure sensor detects the pressure at the outlet in real time, converting the water pressure information at the outlet into the angle that needs to be adjusted, and then feeding it back to the controller to adjust the valve core angle until the water pressure reaches the target value. This achieves sensor information feedback, and the process is a closed-loop execution, with a simple structure and convenient control.

[0005] When testing road permeability, it has the advantage of maintaining a constant pressure inside the glass tube, improving the accuracy and reliability of the test results. When the water level inside the glass tube begins to drop, the rubber disc moves down with the water level through the cooperation of the electric push rod and the pressure sensor, effectively ensuring that the inside of the glass tube can always be kept at a constant pressure, reducing the impact of water pressure changes on the accuracy of the test results, and thus effectively improving the accuracy of the test results.

[0006] The beneficial effects of this invention include: This invention provides a road surface permeability testing device, comprising: a water outlet component, a sealing component, a base, and two counterweight plates. The sealing component uses sealing mud. During the permeability testing process, the sealing mud placed between the road surface and the device can fill the gap between the device and the road surface, preventing water inside the device from leaking into the surrounding area of ​​the testing device through the gap. The sealing mud effectively ensures the stability of the testing environment and the accuracy of the test results. Furthermore, when this device tests the permeability at different testing points, the sealing mud needs to be replaced each time, which further ensures the sealing effect of the sealing mud on the gaps between the device and the road surface, reduces the impact of water pressure changes during permeability testing on the accuracy of the test results, effectively improves the accuracy of the test results, and saves on the cost of using road surface permeability testing.

[0009] Embodiments of the present invention are described in detail below, examples of which are illustrated 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 intended to explain the present invention, and should not be construed as limiting the present invention.

[0010] This invention discloses a ground permeability testing device for highway maintenance, comprising: a water outlet component 6, a sealing component 2, a base 1, and two counterweights. A support frame 3 is mounted on the base 1, and pulleys 4 are mounted on the bottom of the support frame 3. The sealing component 2 includes sealing mud 7. During the permeability testing process, the sealing mud 7 placed between the road surface and the device can fill the gap between the device and the road surface, preventing water inside the device from leaking into the surrounding area of ​​the testing device through the gap. The sealing mud 7 effectively ensures the stability of the testing environment and the accuracy of the testing results. Furthermore, when this device tests the permeability of different testing points, the sealing mud 7 needs to be replaced each time, which can further ensure the sealing effect of the sealing mud 7 on the gaps between the device and the road surface.

[0011] The water outlet assembly 6 includes: a valve body, a valve core, a water pressure sensor, a controller 5, a main detector, a support plate 11, and an auxiliary detector 8. The valve body has an inlet and an outlet, and is mounted on the support plate 11, which is located on the upper surface of the base 1. The valve core is rotatably mounted on the valve body, meaning it can rotate relative to the valve body, and during rotation, it regulates the water flow between the inlet and outlet. Thus, a corresponding drive structure can be provided to drive the valve core, thereby achieving active control of the water flow. Controller 5 controls the rotation of the valve core based on the detection value of the water pressure sensor. Controller 5 can be connected to a power source, such as a drive motor, to control the rotation of the valve core relative to the valve body. After the water pressure sensor detects the water pressure at the outlet, it outputs the water pressure value to the control module. The control module analyzes and calculates the water pressure value, and when the water pressure value differs from the target pressure value, it converts the pressure difference into a rotation angle. The control module then sends the obtained rotation angle to controller 5, which controls the corresponding drive structure to drive the valve core at the corresponding rotation angle. That is, when the water pressure value is the same as the target value, there is no need to drive the valve core to rotate. When the water pressure value is less than or greater than the target value, the valve core can be driven to rotate in the forward or reverse direction, thus ensuring that the adjusted water pressure meets the water supply requirements. The water pressure sensor detects the pressure at the outlet in real time, converting the water pressure information at the outlet into the angle that needs to be adjusted, and then feeding it back to controller 5 to adjust the valve core angle until the water pressure reaches the target value. This achieves sensor information feedback, and the process is a closed-loop execution, with a simple structure and convenient control.

[0012] When testing road permeability, it has the advantage of maintaining a constant pressure inside the glass tube, improving the accuracy and reliability of the test results. When the water level inside the glass tube begins to drop, the rubber disc moves down with the water level through the cooperation of the electric push rod and the pressure sensor, effectively ensuring that the inside of the glass tube can always be kept at a constant pressure, reducing the impact of water pressure changes on the accuracy of the test results, and thus effectively improving the accuracy of the test results.

[0013] When testing road surface permeability, this device has the advantage of simulating a car driving on the road and the vibrations generated during driving, further improving the accuracy of the test results. As the water level inside the glass bottle continuously decreases, a negative pressure state can be created inside the glass bottle through a rubber disc, thus simulating the effect of a car driving on the road. At the same time, the vibration force generated by multiple electronic vibrators can simulate the vibration effect of a car driving on the road, thereby better simulating the actual stress and deformation on the road surface, which further improves the accuracy of the water seepage test results and enables a more accurate assessment of the road surface's water seepage performance.

[0014] By combining the water outlet component 6 and the sealing component 2, the efficiency of permeability testing of ground stones is improved. When water is discharged from the water outlet component 6, the detection timer starts. Water flows from the top to the bottom of the ground stones. When water remains at the bottom, it reacts with quicklime. The sealing component 2 and the information illumination unit stop the timing of the detection unit. Sampling comparisons are performed based on the timing of the detection timer to detect ground permeability. The combination of the water outlet component 6 and the sealing component 2 also saves on permeability testing costs. As the water inside the water outlet component 6 descends, it reacts with quicklime at the bottom of the ground stones, generating gas. This gas pressurizes the sealing component 2. The water and quicklime inside the water outlet component 6 are inexpensive and practical; therefore, this combination saves on the cost of permeability testing for highway surfaces.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
