Description

Technical Field

[0001] The utility model relates to the field of measuring equipment, in particular to a measuring device for the loose paving thickness of an asphalt concrete pavement. Background Art

[0002] With the rapid development of asphalt mixture technology, asphalt concrete pavement has gradually replaced cement concrete pavement. At the same time, my country's transportation roads are also developing rapidly. By the end of 2022, the total mileage of national roads will reach 5.35 million kilometers, an increase of 74,100 kilometers from the end of the previous year. With the huge total mileage of roads, the country has also put forward higher requirements on the quality of road pavement, that is, on the construction quality of asphalt concrete pavement, and the control of asphalt concrete pavement thickness is an extremely important part of asphalt concrete pavement construction quality management.

[0003] The variation of asphalt concrete pavement thickness has a certain impact on its strength, rutting resistance, stability, service life and flatness. The variation of asphalt concrete pavement structure layer thickness is related to its compaction thickness. Under the same rolling process, the final compaction thickness depends on the initial loose paving thickness. Therefore, it is necessary to test the loose paving thickness of asphalt concrete during paving to ensure the construction quality of asphalt concrete pavement.

[0004] At present, detection equipment based on ground penetrating radar has been used to measure pavement thickness. However, since the asphalt concrete pavement during the paving process is relatively loose, the wheels of ordinary detection equipment are easily stuck to the asphalt concrete pavement during the paving process, and the movement resistance is too large, resulting in difficulty for such equipment to move on the asphalt concrete pavement during the paving process, and thus unable to measure the thickness of the asphalt concrete pavement during the paving process. That is, the detection equipment based on ground penetrating radar cannot measure the loose paving thickness of the asphalt concrete pavement.

[0005] The traditional method generally uses the insertion ruler method to measure the loose laying thickness of the asphalt concrete pavement, which requires manual visual reading. Not only is the measurement efficiency low, but the measurement accuracy is greatly affected by human factors. In addition, during the measurement process, only selected points of the asphalt concrete pavement can be measured within the entire length. It is difficult to measure the loose laying thickness of the entire asphalt concrete pavement over the entire length, and it is difficult to objectively reflect the loose laying thickness of the entire asphalt concrete pavement. That is, the accuracy of the loose laying thickness of the asphalt concrete pavement is difficult to guarantee. Utility Model Content

DETAILED DESCRIPTION

[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] The technical solution provides a device for measuring the loose paving thickness of an asphalt concrete pavement, comprising a mobile vehicle 1, a ground penetrating radar 2, a thickness display 3, an oil storage tank 4 and an oil injection pipe 5;

[0033] The ground penetrating radar 2 is arranged at the front end of the mobile vehicle 1, and the ground penetrating radar 2 is used to measure the loose paving thickness of the asphalt concrete pavement during the paving process;

[0034] The thickness display 3 is arranged on the top of the mobile vehicle 1, and the thickness display 3 is electrically connected to the ground penetrating radar 2. The thickness display 3 is used to display the loose paving thickness measured by the ground penetrating radar 2;

[0035] The oil storage tank 4 is arranged in the middle of the mobile vehicle 1, and the oil storage tank 4 is used to store anti-sticking silicone oil;

[0036] At least two fuel injection pipes 5 are provided, and the two fuel injection pipes 5 are respectively provided on the two side walls of the oil storage tank 4, and the inlet of the fuel injection pipe 5 is connected to the outlet of the oil storage tank 4; at least two wheels 11 are provided at the bottom of the mobile vehicle 1, and the outlet of the fuel injection pipe 5 faces the wheel 11, and the fuel injection pipe 5 is used to spray the anti-sticking silicone oil stored in the oil storage tank 4 to the wheel 11.

[0037] In order to use the ground penetrating radar 2 to measure the loose thickness of asphalt concrete pavement and improve the efficiency and accuracy of the measurement, the present technical solution proposes a measuring device for the loose thickness of asphalt concrete pavement, such as Figure 1-3 As shown, it includes a mobile car 1, a ground penetrating radar 2, a thickness display 3, an oil storage tank 4 and an oil injection pipe 5. The ground penetrating radar 2 is arranged at the front end of the mobile car 1. The ground penetrating radar 2 is used to measure the loose paving thickness of the asphalt concrete pavement during the paving process. The ground penetrating radar 2 is a conventionally used bottom penetrating radar in the prior art. Its working principle is: one antenna is used to transmit high-frequency broadband electromagnetic waves, and the other antenna receives the reflected waves from the underground medium interface. When the electromagnetic wave propagates in the medium, its path, electromagnetic field intensity and waveform change with the electrical properties and geometric shape of the medium it passes through. According to the received walking time, amplitude and waveform data, the spatial position and medium structure of the underground interface or geological body are inferred, so as to measure the loose paving thickness of the asphalt concrete pavement. The thickness display 3 is arranged on the top of the mobile car 1. The thickness display 3 is electrically connected to the ground penetrating radar 2. The thickness display 3 is used to display the loose paving thickness measured by the ground penetrating radar 2, which is convenient for reading data at any time and intuitive and clear.

[0038] In order to prevent the wheels 11 of the mobile trolley 1 from sticking to the asphalt pavement during movement, which makes it difficult for the mobile trolley to move on the asphalt concrete pavement during paving, the oil storage tank 4 is arranged in the middle of the mobile trolley 1 in the technical solution. The oil storage tank 4 is used to store anti-sticking silicone oil, and the oil injection pipe 5 is connected to the oil storage tank 4; at least two wheels 11 are arranged at the bottom of the mobile trolley 1, and the outlet of the oil injection pipe 5 faces the wheels 11. The oil injection pipe 5 is used to spray the anti-sticking silicone oil stored in the oil storage tank 4 to the corresponding wheels 11. The anti-sticking silicone oil forms an anti-sticking silicone oil film with a certain thickness on the wheels 11. The anti-sticking silicone oil film is used to separate the wheels 11 from the asphalt concrete pavement during paving, thereby ensuring that the mobile trolley 1 can move smoothly during paving and ensuring that the loose paving thickness of the asphalt concrete pavement can be measured by the ground penetrating radar 2.

[0039] Further explanation, the number of the wheels 11 is four, and the four wheels 11 are respectively located at the four corners of the bottom of the mobile vehicle 1;

[0040] The oil injection pipe 5 includes a connecting pipe 51 and a nozzle 52. The connecting pipe 51 is interconnected with the oil storage tank 4, and the connecting pipe 51 is used to transport the oil from the oil storage tank 4 to the nozzle 52; the middle part of the nozzle 52 is interconnected with the connecting pipe 51, and two nozzles 521 are opened at the end of the nozzle 52, and the two nozzles 521 are respectively directed to the two wheels 11 located on the same side of the mobile vehicle 1, and the nozzles 521 are used to spray the anti-sticking silicone oil transported from the connecting pipe 51 to the nozzle 52 toward the corresponding wheels 11.

[0041] In a preferred embodiment of the present technical solution, four wheels 11 are provided to ensure the stability of the operation of the mobile vehicle 1, which is beneficial to ensuring the stability of the measurement data of the ground penetrating radar 2.

[0042] Furthermore, the fuel injection pipe 5 includes a connecting pipe 51 and a nozzle 52. The connecting pipe 51 is interconnected with the oil storage tank 4. The connecting pipe 51 is used to transport the oil storage tank 4 to the nozzle 52. The middle part of the nozzle 52 is interconnected with the connecting pipe 51, and at least two nozzles 521 (i.e., serving as outlets of the fuel injection pipe 5) are respectively opened at both ends of the nozzle 52. The two nozzles 521 are respectively directed to two wheels 11 located on the same side of the mobile vehicle 1. The nozzles 521 are used to spray the anti-sticking silicone oil transported from the connecting pipe 51 to the nozzle 52 into the corresponding wheels 11, ensuring that each wheel 11 can be sprayed with the anti-sticking silicone oil to form an anti-sticking silicone oil film, which is conducive to ensuring that the mobile vehicle 1 can run smoothly on the asphalt pavement during the paving process.

[0043] Further description, it also includes a spray sensor 6, which is arranged inside the mobile vehicle 1 and located behind the oil storage tank 4. The spray sensor 6 is electrically connected to the oil injection pipe 5, and the spray sensor 6 is used to detect the spraying amount and spraying frequency of the oil injection pipe 5.

[0044] When the anti-sticking silicone film formed by the anti-sticking silicone oil on the wheel 11 is too thin, the wheel 11 is also prone to adhesion with the asphalt concrete pavement during the paving process, affecting the movement of the mobile trolley, which is not conducive to the measurement of the loose paving thickness; when the anti-sticking silicone film formed by the anti-sticking silicone oil on the wheel 11 is too thick, the friction between the wheel 11 and the asphalt concrete pavement during the paving process is insufficient, which also affects the movement of the mobile trolley, which is not conducive to the measurement of the loose paving thickness. Therefore, in a preferred embodiment of the present technical solution, the spraying amount and spraying frequency of the oil injection pipe 5 are detected by setting a conventional spraying sensor 6 (such as the sensor with the model Spary Sensorde produced by A2PS Company). If the spraying amount and spraying frequency of the oil injection pipe 5 are too high or too low, the operator can adjust the spraying amount and spraying frequency of the oil injection pipe 5 according to the spraying amount and spraying frequency obtained by the spraying sensor 6, so that the spraying amount and spraying frequency of the oil injection pipe 5 are suitable, the adjustability and applicability of the equipment are enhanced, and the structure is simple, the performance is reliable, and the requirements of the user are better met.

[0045] Further description, it also includes a spray regulator, which is arranged inside the mobile vehicle 1 and located behind the spray sensor 6. The spray regulator is electrically connected to the fuel injection pipe 5, and the spray regulator is used to adjust the spraying amount and spraying frequency of the fuel injection pipe 5.

[0046] In a preferred embodiment of the present technical solution, the spraying amount and spraying frequency of the fuel injection pipe 5 are adjusted by setting a conventional spray regulator (not shown in the figure, such as a knob, etc.). If the spraying amount and spraying frequency of the fuel injection pipe 5 are too high or too low, the operator can use the spray regulator to adjust the spraying amount and spraying frequency of the fuel injection pipe 5 according to the spraying amount and spraying frequency obtained by the spray sensor 6, so that the spraying amount and spraying frequency of the fuel injection pipe 5 are appropriate, thereby enhancing the adjustability and applicability of the equipment, and the structure is simple, the performance is reliable, and the requirements of users are better met.

[0047] Further explanation, it also includes a power supply device 7, the power supply device 7 is located on the top of the mobile vehicle 1, the power supply device 7 is located behind the thickness display 3, the power supply device 7 is electrically connected to the ground penetrating radar 2 and the fuel injection pipe 5, and the power supply device 7 is used to power the ground penetrating radar 2 and the fuel injection pipe 5;

[0048] The power supply device 7 includes an electrically connected battery 71 and a voltage conversion output device 72, wherein the battery 71 is used to store low-voltage electrical energy; the voltage conversion output device 72 is electrically connected to the ground penetrating radar 1 and the fuel injection pipe 5, and the voltage conversion output device 72 is located in front of the battery 71. The voltage conversion output device 72 is used to convert the low-voltage electrical energy stored in the battery 71 into high-voltage electrical energy.

[0049] In a preferred embodiment of the present technical solution, a power supply device 7 is provided to provide power to the ground penetrating radar 2 and the fuel injection pipe 5, so that the ground penetrating radar 2 and the fuel injection pipe 5 can work normally, which is conducive to ensuring that the measurement of the loose paving thickness can be carried out smoothly.

[0050] Furthermore, the power supply device 7 includes an electrically connected battery 71 and a voltage conversion output device 72, the battery 71 is used to store low-voltage electrical energy; the voltage conversion output device 72 is electrically connected to the ground penetrating radar 1 and the fuel injection pipe 5, and the voltage conversion output device 72 is used to convert the low-voltage electrical energy stored in the battery 71 into high-voltage electrical energy, thereby providing the high-voltage electrical energy required for the operation of the ground penetrating radar 2 and the fuel injection pipe 5.

[0051] To further explain, a battery charging port and a maintenance port are provided on the side wall of the power supply device 7 , wherein the battery charging port is used to charge the storage battery 71 , and the maintenance port is used to maintain the power supply device 7 .

[0052] In a preferred embodiment of the present technical solution, a battery charging port (not shown) is provided to charge the battery 71 so that the battery 71 has sufficient electrical energy, thereby ensuring that the power supply device 7 can provide the high-voltage electrical energy required for the bottom-penetrating radar 2 and the fuel injection pipe 5 to operate.

[0053] Furthermore, by providing an inspection port (not shown in the figure), when the storage battery 71 and the voltage conversion output device 72 need to be replaced and repaired, they can be replaced through the inspection port.

[0054] Further, the side wall of the oil storage tank 4 is provided with a liquid injection port, and the liquid injection port is used to inject the anti-sticking silicone oil into the oil tank;

[0055] The side wall of the mobile trolley 1 is provided with an avoidance position, and the avoidance position is used to avoid the injection port;

[0056] The mobile vehicle further comprises a sealing cover 12, which is installed at the avoidance position and is used to open and close the avoidance position.

[0057] In a preferred embodiment of the present technical solution, a liquid injection port (not shown in the figure) is opened on the top of the oil storage tank 4, and an avoidance position (not shown in the figure) is set on the top of the mobile cart 1, and the avoidance position is used to avoid the liquid injection port. The mobile cart also includes a sealing cover 12, which is installed in the avoidance position. The sealing cover 12 is used to open and close the avoidance position to prevent the anti-sticking silicone oil in the oil storage tank 4 from flowing into the interior of the mobile cart 1, which is beneficial to improve the sealing of the oil storage tank 4.

[0058] Further description, it also includes a vehicle speed sensor, which is located inside the mobile vehicle 1 and in front of the oil storage tank 4 , and is used to detect the running speed of the mobile vehicle 1 .

[0060] It is further explained that the ground penetrating radar 2 is a laser radar.

[0061] Since laser radar has the advantages of low cost, high precision, high resolution and strong anti-interference ability, it is sufficient to measure the loose paving thickness of asphalt concrete pavement.

[0062] Further description, the fuel tank 4 and the fuel injection pipe 5 are both made of stainless steel; the wheel 11 is a rubber tire.

[0063] Since stainless steel has good corrosion resistance and oxidation resistance, it is suitable for high temperature and corrosion resistant environment. Therefore, the technical solution is conducive to improving the service life of the oil storage tank 4 and the oil injection pipe 5 by limiting the material of the oil storage tank 4 and the oil injection pipe 5 to stainless steel.

[0064] Since the rubber tire has a high hardness and can resist various friction forces, it also has good anti-aging ability, can effectively resist the damage of external ultraviolet rays, and maintain good appearance performance; in addition, it can effectively reduce the impact of vibration on the mobile car 1 and improve the stability of operation. Therefore, in a preferred embodiment of the present technical solution, the wheel 11 is limited to a rubber tire, which increases the service life of the wheel 11 and improves the operational stability of the mobile car 1.
