Abstract
Description
Technical Field
[0001] This invention relates to a vehicle for measuring the width and thickness of concrete roads and its measurement method, belonging to the field of concrete road inspection technology. Background Technology
[0002] According to the standards for quality inspection and evaluation of highway engineering, the width and thickness of concrete pavement need to be tested. Currently, steel rulers are commonly used to measure the width and thickness of concrete pavement. For measuring the width, the inspector uses a steel ruler to measure the width of the pavement horizontally along the road centerline. For measuring the thickness, the inspector drills a core sample in the pavement and then measures the thickness of the core sample, i.e., the thickness of the pavement structural layer, with a steel ruler; or the thickness of both sides of the pavement can be measured directly. However, these commonly used methods for measuring the width and thickness of concrete pavement have the following shortcomings:
[0003] First, when the road surface has camber, cross slope, or longitudinal slope, the inspectors use a steel ruler to measure against the ground. This not only fails to keep the surface perfectly level but also causes the measurement to tilt, leading to inaccurate measurement results and affecting the authenticity of the project quality.
[0004] Secondly, the drilling method for detecting the thickness of concrete pavement involves drilling core samples from the pavement and then estimating the thickness of the concrete pavement by measuring the back of the core samples. This not only damages the integrity of the pavement structure layers but also requires multiple people to operate, which is time-consuming and labor-intensive. Directly measuring the thickness of the pavement on both sides cannot reflect the true thickness of the pavement, and the measurement results have significant limitations.
[0005] Third, because the surveyors use handheld steel rulers to measure, it is difficult to guarantee true horizontality and verticality based on experience and intuition, making it difficult to accurately obtain the true width and thickness of the concrete pavement.
[0006] Fourth, in accordance with the requirements for engineering quality testing and evaluation, the measurement station number needs to be accurately recorded when measuring the width and thickness of concrete pavement. This requires surveyors to carry a GPS navigation system for real-time positioning and measurement. Therefore, when measuring the width and thickness of concrete pavement, it is necessary to carry a variety of instruments and equipment, which greatly increases the number of personnel and affects work efficiency. Summary of the Invention

A transverse angle disk is mounted on the transverse rotating rod, and a transverse angle line is on the transverse angle disk. A vertical scale is mounted at the bottom of the transverse angle disk, and the vertical scale has a vertical groove, a movable caliper, a buckle, and a measuring stylus.
[0012] As an improvement to the above technical solution, the rectangular sliding frame includes a horizontal scale and a sliding rod. The horizontal scale is controlled to extend and retract by a fixed button No. 1, and a slide rail is provided inside it. A spherical slider is mounted on the slide rail. The sliding rod is controlled to extend and retract by a fixed button No. 2, and a circular slider is fitted on the slide rod. Sliding drivers are installed at the left and right ends of the rectangular sliding frame.

[0014] As an improvement to the above technical solution, the sliding driver is equipped with a No. 2 motor in the horizontal direction; the No. 2 motor drives the threaded rod on the transmission rod to rotate through a gear; a traction line is wound on the threaded rod; and the traction line is connected to the horizontal connecting rod of the width measuring device; the No. 2 motor is connected to the No. 2 solar panel through a No. 2 wire.
[0015] As an improvement to the above technical solution, the distance recorder is connected to the rotation driver and the fixed ring respectively via a fixed round rod; the fixed ring is connected to the U-shaped frame via a movable rod, and a transmitter is installed in the middle of the U-shaped frame, with a receiver controller installed on the transmitter; a transmitter controller is installed on the side of the small wheel, and the small wheel is installed on the U-shaped frame via a collar.
[0016] As an improvement to the above technical solution, the electronic controller is mounted on a vertical support rod by a bracket, and a display screen is provided on it. The electronic controller is also equipped with buttons for controlling the rotation driver, the sliding driver, and the distance recorder.
[0017] The above-mentioned method for measuring the width and thickness of concrete roads using a measuring vehicle includes the following steps:
[0018] Step 1: Using the electronic controller, move the measuring vehicle to the original coordinate control zero point and simultaneously activate the distance recorder. At this time, the transmitter and receiver controllers on the distance recorder are aligned, and the transmitter connects and matches with the electronic controller. The electronic controller displays the number of small wheel rotations (0) and the fixed wheel circumference (L1). Then, based on the measurement quantity and the location of the next measurement point, move the measuring vehicle to the target point. After the measuring vehicle stabilizes, temporarily stop the distance recorder. The data transmitter on the distance recorder then transmits the specific number of small wheel rotations (N) to the electronic controller. The surveyor records the movement distance L = L1·N displayed on the electronic controller and calculates the station number of the target point based on the original coordinate control zero point. No additional GPS is required; efficient and accurate operation can be performed by just one person.
[0019] Step 2: Adjust the thickness measuring device according to the width of the concrete pavement at the measurement point. First, adjust the left and right thickness measuring devices to both sides of the concrete pavement using the horizontal telescopic rod. At the same time, adjust the measuring ruler probe to the bottom of the concrete pavement and the subgrade interface using the vertical telescopic rod according to the pavement thickness. Since the longitudinal angle plate of the thickness measuring device can be kept vertical in the longitudinal direction by the internal rotating bearing, and the transverse angle plate can be kept vertical in the transverse direction by the transverse angle plate, the transverse and longitudinal angle plates can be used to automatically calibrate the transverse and longitudinal tilt angles of the concrete pavement. Record the deviation angles in the two directions according to the transverse and longitudinal angle lines. Next, move the movable caliper on the measuring ruler to be parallel to the pavement on the vertical slide. After the thickness measuring device is stable in the transverse and longitudinal directions, fix the movable caliper with the buckle. Read the angles θ1 and θ2 of the longitudinal and transverse angle plates and the thickness h1 data on the measuring ruler. The probe length is fixed at c1. Finally, calculate the thickness of the concrete pavement based on the longitudinal and transverse angles, the thickness, and the probe length. If the road surface is longitudinally inclined, the actual thickness is: H = H1·cosθ1 + C1; if the road surface is transversely inclined, the actual thickness is: H = H1·cosθ2 + C1; if the road surface is inclined both longitudinally and transversely, the actual thickness is: H = H1·cosθ1·cosθ2 + C1. Avoid using steel rulers to measure the inclined thickness or core drilling measurements, as this could affect the stability of the road surface structure.
[0020] Step 3: Based on the width of the concrete pavement at the measurement point, activate the electronic controller to move the width measuring device along the slide rail and slider to the left end of the pavement. Align the laser probe with the left curb. Since the width measuring device is equipped with a mechanism that uses gravity to maintain horizontal and vertical alignment, the horizontal rotator and vertical slider on the width measuring device can be used to keep the laser probe horizontal and vertical. Once the width measuring device is stable, record the data D1 on the horizontal scale of the rectangular slide frame. Repeat the same procedure, activating the electronic controller to move the width measuring device along the slide rail and slider to the right end of the pavement. Align the laser probe with the right curb. Once the width measuring device is stable, record the data D2 on the horizontal scale of the rectangular slide frame. Calculate the true horizontal width of the concrete pavement, D = D1 - D2. This method avoids data inaccuracies obtained by two people using a steel tape measure when the pavement is uneven, has camber, cross slope, or longitudinal slope.
[0021] Step 4: Record the station number, thickness, and width of the concrete pavement at each measuring point according to the specifications.
[0022] Step 5: Continue measuring the corresponding data of the next test point according to steps one through four above, and finally complete the data collection of the thickness and width of the concrete pavement of the section.
[0023] The concrete road width and thickness measuring vehicle and its implementation method described in this invention have the following advantages compared to the prior art:
[0024] 1. By setting up a distance recorder and a rotation driver, the station number of the measured point can be recorded at any time by relying on the motor, rotation bearing, transmitter, transmitter controller, receiver controller, etc., without having to carry a separate GPS recorder.
[0025] 2. By setting up a thickness recorder, the vertical telescopic rod, longitudinal angle plate, transverse angle plate, transverse rotating rod, horizontal ring, measuring ruler, moving caliper and measuring needle can work together to make angle correction measurements possible for cross-sectional and longitudinal inclinations in concrete pavement thickness measurement. This ensures vertical and accurate measurements and improves the accuracy of concrete pavement measurement.
[0026] 3. By setting up a width measuring device, the sliding driver, rectangular sliding frame, slide rail, slide rod, circular slider, spherical slider, indicator needle, vertical connecting rod, arc-shaped slide groove, longitudinal slider, transverse rotator, horizontal control ring, and laser probe work together to avoid the need for inspectors to use steel rulers to measure the width of concrete pavement, which may affect the measurement results due to inability to keep the surface level. The device can move left and right and automatically maintain a horizontal position to measure the width of concrete pavement, making it highly efficient and accurate.
[0027] 4. By integrating the rotary drive, thickness measuring device, rectangular sliding frame, width measuring device, sliding drive, distance recorder, and electronic controller into a single structure, the measuring vehicle not only meets the measurement needs under different road surfaces, but also simplifies operation, reduces personnel, and improves overall measurement efficiency and accuracy.
[0028] 5. By installing solar panels, the power source for the driving equipment of the measuring vehicle is ensured to rely on solar energy, which is green, environmentally friendly, and cost-effective. Attached Figure Description

[0045] The above-mentioned method for implementing a concrete road width and thickness measuring vehicle includes the following steps:
[0046] Step 1: Using the electronic controller, move the measuring vehicle to the original coordinate control zero point and simultaneously activate the distance recorder. At this time, the transmitter and receiver controllers on the distance recorder are aligned, and the transmitter connects and matches with the electronic controller. The electronic controller displays the number of small wheel rotations (0) and the fixed wheel circumference (L1). Then, based on the measurement quantity and the location of the next measurement point, move the measuring vehicle to the target point. After the measuring vehicle stabilizes, temporarily stop the distance recorder. The data transmitter on the distance recorder then transmits the specific number of small wheel rotations (N) to the electronic controller. The surveyor records the movement distance L = L1·N displayed on the electronic controller and calculates the station number of the target point based on the original coordinate control zero point. No additional GPS is required; efficient and accurate operation can be performed by just one person.
[0047] Step 2: Adjust the thickness measuring device according to the width of the concrete pavement at the measurement point. First, adjust the left and right thickness measuring devices to both sides of the concrete pavement using the horizontal telescopic rod. At the same time, adjust the measuring ruler probe to the bottom of the concrete pavement and the subgrade interface using the vertical telescopic rod according to the pavement thickness. Since the longitudinal angle plate of the thickness measuring device can be kept vertical in the longitudinal direction by the internal rotating bearing, and the transverse angle plate can be kept vertical in the transverse direction by the transverse angle plate, the transverse and longitudinal angle plates can be used to automatically calibrate the transverse and longitudinal tilt angles of the concrete pavement. Record the deviation angles in the two directions according to the transverse and longitudinal angle lines. Next, move the movable caliper on the measuring ruler to be parallel to the pavement on the vertical slide. After the thickness measuring device is stable in the transverse and longitudinal directions, fix the movable caliper with the buckle. Read the angles θ1 and θ2 of the longitudinal and transverse angle plates and the thickness h1 data on the measuring ruler. The probe length is fixed at c1. Finally, calculate the thickness of the concrete pavement based on the longitudinal and transverse angles, the thickness, and the probe length. If the road surface is longitudinally inclined, the actual thickness is: H = H1·cosθ1 + C1; if the road surface is transversely inclined, the actual thickness is: H = H1·cosθ2 + C1; if the road surface is inclined both longitudinally and transversely, the actual thickness is: H = H1·cosθ1·cosθ2 + C1. Avoid using steel rulers to measure the inclined thickness or core drilling measurements, as this could affect the stability of the road surface structure.
[0048] Step 3: Based on the width of the concrete pavement at the measurement point, activate the electronic controller to move the width measuring device along the slide rail and slider to the left end of the pavement. Align the laser probe with the left curb. Since the width measuring device is equipped with a mechanism that uses gravity to maintain horizontal and vertical alignment, the horizontal rotator and vertical slider on the width measuring device can be used to keep the laser probe horizontal and vertical. Once the width measuring device is stable, record the data D1 on the horizontal scale of the rectangular slide frame. Repeat the same procedure, activating the electronic controller to move the width measuring device along the slide rail and slider to the right end of the pavement. Align the laser probe with the right curb. Once the width measuring device is stable, record the data D2 on the horizontal scale of the rectangular slide frame. Calculate the true horizontal width of the concrete pavement, D = D1 - D2. This method avoids data inaccuracies obtained by two people using a steel tape measure when the pavement is uneven, has camber, cross slope, or longitudinal slope.
[0049] Step 4: Record the station number, thickness, and width of the concrete pavement at each measuring point according to the specifications.
[0050] Step 5: Continue measuring the corresponding data of the next test point according to steps one through four above, and finally complete the data collection of the thickness and width of the concrete pavement of the section.

7. A measurement method for a concrete road width and thickness measuring vehicle according to claim 5, characterized in that, Includes the following steps: Step 1: The electronic controller moves the measuring vehicle to the original coordinate control zero point, and the distance recorder is activated simultaneously. At this time, the transmitter and receiver controllers on the distance recorder are aligned, and the transmitter is connected to the electronic controller for matching. The electronic controller displays the number of small wheel rotations as 0 and the fixed circumference of the wheel as L1. Then, based on the measurement quantity and the location of the next measurement point, the measuring vehicle is driven to the measurement point. After the measuring vehicle stabilizes, the distance recorder is temporarily set. At this time, the data transmitter on the distance recorder transmits the specific number of small wheel rotations N to the electronic controller. The surveyor records the movement distance L = L1·N on the display screen of the electronic controller, and then calculates the station number of the measurement point based on the original coordinate control zero point. Step Two: Adjust the thickness measuring device according to the width of the concrete pavement at the measurement point. First, use the horizontal telescopic rod to adjust the left and right thickness measuring devices to both sides of the concrete pavement. Simultaneously, adjust the measuring ruler's probe to the bottom of the concrete pavement and the subgrade interface using the vertical telescopic rod, based on the pavement thickness. Since the longitudinal angle dial of the thickness measuring device can be kept vertical by its internal rotating bearing, and the transverse angle dial is kept vertical by its transverse angle, the transverse and longitudinal angle dials are used to automatically calibrate the transverse and longitudinal tilt angles of the concrete pavement. Record the deviation angles in both directions based on the transverse and longitudinal angle lines. Then, move the measuring ruler... The ruler is moved along the vertical groove until it is parallel to the road surface. After the thickness measuring device is stable in both the longitudinal and transverse directions, the moving caliper is fixed with a clip. The angles θ1 and θ2 of the longitudinal and transverse angle discs and the thickness H1 data on the measuring ruler are read. The length of the probe is fixed at C1. Finally, the thickness of the concrete pavement is calculated based on the longitudinal and transverse angles, the thickness, and the probe length. If the pavement is longitudinally inclined, the actual thickness is: H = H1·cosθ1 + C1; if the pavement is transversely inclined, the actual thickness is: H = H1·cosθ2 + C1; if the pavement is inclined in both the longitudinal and transverse directions, the actual thickness is: H = H1·cosθ1·cosθ2 + C1. Step 3: Based on the width of the concrete pavement at the measurement point, activate the electronic controller to move the width measuring device along the slide rail and slider to the left end of the pavement. Align the laser probe with the left curb. Since the width measuring device is equipped with a mechanism that uses gravity to maintain horizontal and vertical alignment, use the horizontal rotator and vertical slider on the width measuring device to keep the laser probe horizontal and vertical at all times. Once the width measuring device is stable, record the data D1 on the horizontal scale of the rectangular sliding frame. Activate the electronic controller to move the width measuring device along the slide rail and slider to the right end of the pavement. Align the laser probe with the right curb. Once the width measuring device is stable, record the data D2 on the horizontal scale of the rectangular sliding frame. Calculate the actual horizontal width of the concrete pavement, D = D... 1- D2; Step 4: Record the station number, thickness, and width of the concrete pavement at each measuring point according to the specifications. Step 5: Continue measuring the corresponding data of the next test point according to steps one through four above, and finally complete the data collection of the thickness and width of the concrete pavement of the section.
