[0002] In the construction of road and bridge-tunnel engineering, road compaction degree is one of the key indicators to measure the project quality. The traditional methods for detecting road compaction degree mainly include the core cutter method, sand replacement method, nuclear densitometer method, etc. Subgrade compaction degree is one of the key indicators for detecting the construction quality of subgrade and pavement. It represents the density condition after on-site compaction. The higher the compaction degree, the greater the density and the better the overall performance of the material. For subgrade, semi-rigid base of pavement and granular flexible base, the compaction degree refers to the ratio of the actual dry density achieved on the construction site to the maximum dry density obtained from the indoor standard experiment; for asphalt surface course and asphalt stabilized base, the compaction degree refers to the ratio of the density achieved on-site to the indoor standard density.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1: As Figures 1-9 shown, the present invention provides a technical solution: a road compaction degree intelligent detection instrument for road and bridge-tunnel projects, including an intelligent compaction degree detection mechanism 1. An outer shell mechanism 2 is arranged on the outside of the intelligent compaction degree detection mechanism 1. Lifting control mechanisms 3 are symmetrically installed on both sides of the intelligent compaction degree detection mechanism 1. A cleaning mechanism 4 is arranged on the bottom side of the outer shell mechanism 2. Moving mechanisms 5 are symmetrically installed on both sides of the outer shell mechanism 2. The intelligent compaction degree detection mechanism 1 includes an intelligent detector 101. The bottom of the intelligent detector 101 is fixedly connected with an intelligent detection seat 105. The outer shell mechanism 2 includes a shell body 201. The shell body 201 is arranged on the outside of the intelligent detector 101. A flip cover plate 202 is movably installed on the top of the shell body 201. A lifting opening 204 is penetrated and opened at the bottom of the shell body 201;

[0034] The lifting control mechanism 3 includes a lifting cylinder 301. The lifting cylinders 301 are symmetrically arranged on both sides of the intelligent detector 101. The output end of the lifting cylinder 301 is connected with a pneumatic telescopic rod 302. The bottom end of the pneumatic telescopic rod 302 is fixedly connected with a connecting plate 303. The connecting plates 303 are fixedly connected to both sides of the intelligent detector 101. A side mounting frame 304 is fixedly installed on one side of the lifting cylinder 301. A mounting seat 305 is installed on the side surface of the side mounting frame 304. The mounting seats 305 are fixedly installed on both sides of the inner wall of the outer shell 201.

[0035] Electric telescopic rods 203 are symmetrically and movably connected to the inner wall of the outer shell 201. The output end of the electric telescopic rod 203 is movably connected to the inner wall of the flip cover plate 202. A through groove 205 is penetrated and opened on one side of the outer shell 201. A bottom cover plate 206 is movably connected to the inside of the through groove 205. A rotating shaft 207 is arranged on the side surface of the outer shell 201. One end of the rotating shaft 207 is connected with a limit baffle 208. Anti-slip strips 209 are arranged on the side surface of the limit baffle 208.

[0036] A smart touch screen 102 is fixedly installed on the top of the intelligent detector 101. A control switch 103 and control buttons 104 are arranged on the top of the intelligent detector 101.

[0037] In this embodiment, the intelligent detector 101 is arranged inside the outer housing 201. The cooperation between the outer housing 201 and the flip cover 202 provides effective protection for the intelligent detector 101. The lifting port 204 facilitates the cooperation with the lifting control mechanism 3 to provide a space for lifting, which is convenient for rapid detection work. Among them, the electric telescopic rod 203 uses an electric control method to provide the operation of electrically controlling the opening and closing of the flip cover 202, improving the convenience of operation. The through groove 205 facilitates providing a space for the bottom cover 206 to slide out, so that it is convenient to slide out the bottom cover 206 from the side during detection, making the lifting port 204 open to facilitate moving out the intelligent detection seat 105 for detection work. The rotating shaft 207 provides a rotating function for the installation of the limit baffle 208, facilitating the upward flipping of the limit baffle 208 to fit against the side of the outer housing 201 after the bottom cover 206 slides out, and providing a limit fastening function through the limit baffle 208. The anti-slip strip 209 further enhances the anti-slip effect, which is beneficial to ensuring the stability during limiting. Among them, the intelligent detection seat 105 is the main body of nuclear detection. The nuclear density moisture meter utilizes the rays generated by radioactive elements (such as cesium-137 or americium-241). These radioactive elements emit gamma rays. When the gamma rays enter the material to be measured, they will interact with the atoms in the material. The main interactions between gamma rays and matter include the photoelectric effect, Compton scattering, and pair production effect, etc. In nuclear density detection, Compton scattering is mainly utilized. When a gamma ray photon undergoes Compton scattering with an electron in the material, the photon will lose a part of its energy and change its direction of motion. The number and energy of the scattered gamma rays are related to the electron density in the material. The greater the density of the material, the more electrons there are per unit volume, the greater the probability of Compton scattering of gamma rays with electrons, and the fewer scattered gamma rays received by the detector. By measuring the intensity of the scattered gamma rays, the density of the material can be deduced.

[0038] The lifting cylinder 301 is connected to the connecting plate 303 through the pneumatic telescopic rod 302. The connecting plate 303 is fixed on both sides of the intelligent detector 101. At the same time, the side of the lifting cylinder 301 is connected and fixed to the mounting seat 305 on the inner wall of the outer housing 201 through the side mounting frame 304. The lifting cylinder 301 pneumatically controls the intelligent detector 101 to descend inside the outer housing 201. Before descending, the bottom cover 206 is opened, and then the intelligent detection seat 105 contacts the ground. The intelligent detection seat 105 fully supports the ground, and then the intelligent detector 101 is started to detect the compactness of the road. The operation method is convenient. After the detection is completed, the lifting cylinder 301 drives the pneumatic telescopic rod 302 to contract, which can drive the intelligent detector 101 and the intelligent detection seat 105 to rise, and retract them into the inner part of the outer housing 201. Then the bottom cover 206 is closed, which can provide effective protection for the compactness intelligent detection mechanism 1, avoiding the problem of damage caused by collision and reducing the detection accuracy.

[0039] The display control of the device is facilitated through the intelligent touch screen 102, and the power-on and power-off of the device are facilitated through the control switch 103. The control button 104 is beneficial for providing the control of physical buttons, ensuring stable operation. During operation, a radioactive isotope is built in as a gamma-ray source. Gamma rays have strong penetration ability. When gamma rays are emitted and penetrate the road material to be detected, some rays will interact with the atoms in the material, mainly losing energy and changing direction through ways such as the photoelectric effect, Compton scattering, and electron pair effect. Among them, an intelligent nuclear densitometer usually contains a radioactive source, and generally radioactive isotopes such as cesium-137 or cobalt-60 are used. These radioactive isotopes continuously emit gamma rays. Gamma rays are a kind of high-energy electromagnetic wave with strong penetration ability and can penetrate the material to be detected. When gamma rays enter the material to be detected, they will interact with the electrons in the material and produce Compton scattering. During the Compton scattering process, the energy and direction of gamma rays will change, and the degree of scattering is related to the electron density in the material. And the density of the material is related to the electron density. The denser the material, the higher the electron density, and the stronger the scattering of gamma rays. Gamma rays may also have a photoelectric effect with the atoms in the material, that is, gamma rays transfer all their energy to the electrons in the atoms, causing the electrons to escape from the atoms. The probability of the photoelectric effect is also related to the density of the material. The greater the material density, the higher the possibility of the photoelectric effect occurring. The intelligent nuclear densitometer is equipped with detectors, such as scintillation detectors or semiconductor detectors, etc. The role of the detector is to receive the gamma rays scattered or absorbed by the material to be detected and convert them into electrical signals. The detector will generate corresponding electrical pulse signals according to information such as the intensity and energy of the received gamma rays. The magnitude and quantity of these electrical signals are proportional to the intensity and energy of gamma rays. The electronic circuit in the instrument will amplify, shape, etc. the electrical signals generated by the detector, and then transmit them to the data processing system. The data processing system will calculate the scattering, absorption, etc. of gamma rays in the material to be detected according to the received electrical signals. By establishing corresponding mathematical models and algorithms, these measurement data are converted into the density value of the material.

[0040] Example 2: As Figure 7 and Figure 8As shown in the figure, the cleaning mechanism 4 includes an air tank 401. One end of the air tank 401 is provided with an air filling pump 402. One end of the air tank 401 is fixedly connected with an air delivery hose 403. One end of the air delivery hose 403 is fixedly connected with a jet box 411. A number of high-pressure jet nozzles 404 are symmetrically and evenly distributed on both sides of the jet box 411. A number of cleaning brushes 405 are evenly distributed on the bottom of the jet box 411. The top of the jet box 411 is fixedly connected with a sliding adjustment 406. One end of the sliding adjustment 406 is slidably connected with an adjustment slide rail 407. The top of the adjustment slide rail 407 is connected with the bottom of the outer housing 201. An adjustment lead screw 408 is installed through the inside of the adjustment slide rail 407. One end of the adjustment lead screw 408 is connected with a motor 409. The motor 409 is installed at one end of the adjustment slide rail 407. The other end of the sliding adjustment 406 is slidably connected with a guiding slide rail 410. The top of the guiding slide rail 410 is connected with the bottom of the outer housing 201.

[0041] In this embodiment, the air filling pump 402 works to fill compressed gas into the air tank 401. Before detection is required, by opening the valve at the end of the air tank 401, the high-pressure gas is conveyed to the jet box 411 through the air delivery hose 403. The high-pressure gas is distributed to the position of each high-pressure jet nozzle 404 through the jet box 411 and is ejected at high pressure through the high-pressure jet nozzles 404, thereby realizing an effective cleaning effect, which is beneficial to quickly cleaning the detection position. At the same time, the motor 409 drives the adjustment lead screw 408 to rotate, which can drive the sliding adjustment 406 to move parallel on the adjustment slide rail 407, and then drive the cleaning brush 405 to move to provide a cleaning effect on the ground, which is beneficial to improving the cleaning effect. And during the jetting process, it can move at the same time, effectively increasing the cleaning range and ensuring the cleaning effect, thereby being beneficial to improving the detection effect and avoiding the situation that the detection is incorrect due to sand and gravel.

[0042] Embodiment 3: As Figure 9 shown in the figure, the moving mechanism 5 includes a first-level lifting column 501. The bottom of the first-level lifting column 501 is provided with a steering shaft 502. The bottom of the steering shaft 502 is connected with a bottom support socket 503. A second-level lifting column 504 is movably installed inside the bottom support socket 503. The bottom end of the second-level lifting column 504 is connected with a moving wheel frame 505. Guide rail strips 506 are symmetrically arranged on the inner wall of the bottom support socket 503. Guide blocks 507 are slidably connected to the inside of the guide rail strips 506. The guide blocks 507 are symmetrically installed on both sides of the top of the moving wheel frame 505.

[0043] In this embodiment, the first-level lifting columns 501 are arranged on both sides of the outer housing 201. A steering shaft 502 is connected to the bottom of the first-level lifting column 501, which facilitates the functions of lifting adjustment and rotation. The bottom of the steering shaft 502 is connected to a bottom support sleeve seat 503. A moving wheel frame 505 is built inside the bottom support sleeve seat 503 and is lifted and supported by a second-level lifting column 504. Furthermore, when it is not detected that movement is needed, the first-level lifting column 501 is used to push the steering shaft 502 and the bottom support sleeve seat 503 to descend, so that the bottom of the bottom support sleeve seat 503 supports on the ground. Subsequently, the second-level lifting column 504 is used to push the moving wheel frame 505 to descend, so that the moving wheel frame 505 supports on the ground. Thus, it is convenient to move the entire device by pushing the outside of the outer housing 201, avoiding the time-consuming and laborious process of carrying by hand. During the lifting process, the guide block 507 is slidably connected to the inside of the guide rail 506, which is beneficial for providing lifting guidance and ensuring the stability of use. When in detection use, the first-level lifting column 501 and the second-level lifting column 504 are contracted and stored on both sides of the outer housing 201, reducing the obstruction outside the intelligent detection seat 105 during detection and ensuring the detection accuracy.

[0044] In the present invention, when the intelligent road compaction detection instrument for road bridge and tunnel engineering is used, firstly, compressed gas is added to the inside of the gas tank 401 through the gas pump 402. Before the detection is needed, the valve at the end of the gas tank 401 is opened to transport the high-pressure gas to the jet box 411 through the gas hose 403. The high-pressure gas is distributed to the position of each high-pressure jet nozzle 404 through the jet box 411, and the high-pressure gas is sprayed out through the high-pressure jet nozzle 404, thereby achieving an effective cleaning effect, which is conducive to the rapid cleaning of the detection position. At the same time, the motor 409 drives the adjusting screw rod 408 to rotate, which can drive the sliding adjustment 406 to adjust the sliding The cleaning brush 405 can move parallel to the rail 407, thereby driving the cleaning brush 405 to move and provide a cleaning effect on the ground, which is beneficial to improving the cleaning effect. In addition, the cleaning brush 405 can move simultaneously during the jetting process, which effectively improves the cleaning range and ensures the cleaning effect. The lifting cylinder 301 is connected to the connecting plate 303 in cooperation with the pneumatic telescopic rod 302. The connecting plate 303 is fixed to both sides of the intelligent detector 101. At the same time, the side of the lifting cylinder 301 is connected and fixed to the mounting seat 305 on the inner wall of the outer shell 201 through the side mounting frame 304. The intelligent detector 101 is pneumatically controlled by the lifting cylinder 301 to descend inside the outer shell 201. Before falling, open the bottom cover 206, then make the intelligent detection seat 105 contact the ground, and then start the intelligent detection instrument 101 to detect the compactness of the road. The operation is convenient. After the detection is completed, the pneumatic telescopic rod 302 is retracted by the lifting cylinder 301, which can drive the intelligent detection instrument 101 and the intelligent detection seat 105 to rise and be stored in the interior of the outer shell 201. Then close the bottom cover 206 to provide effective protection for the compaction intelligent detection mechanism 1. The intelligent detection instrument 101 is set inside the outer shell 201, and the outer shell 201 is used to detect the compaction of the road. The cooperation with the flip cover 202 provides effective protection for the intelligent detector 101. The lifting port 204 is convenient for cooperating with the lifting control mechanism 3 to provide lifting space, which is convenient for rapid detection. The electric telescopic rod 203 adopts an electric control method to provide electric control opening and closing operations for the flip cover 202, which improves the convenience of operation. The through groove 205 is convenient for providing a sliding space for the bottom cover 206, so that it is convenient to slide the bottom cover 206 from the side during detection, so that the lifting port 204 is opened to facilitate the removal of the intelligent detection seat 105 for detection. When working, a radioactive isotope is built in as a gamma ray source. Gamma rays have strong penetrating ability. When gamma rays are emitted and penetrate the road material being detected, some rays will interact with the atoms in the material, mainly losing energy and changing direction through the photoelectric effect, Compton scattering and electron pair effect. Among them, Compton scattering is the main basis for density measurement. The number and energy of scattered gamma rays are closely related to the density of the material. The denser the material, the higher the probability of gamma rays interacting with atoms, and the fewer gamma rays are scattered back.The nuclear density meter receives the scattered gamma rays through the detector, and the density of the material can be calculated according to the intensity of the received rays and the calibration curve established in advance. The rotating shaft 207 provides a rotating function for the installation of the limit baffle 208, which is convenient for flipping up and fitting on the side of the outer shell 201 after the bottom cover 206 slides out, and provides a limit buckling effect through the limit baffle 208. The anti-skid effect is further improved by the anti-skid strip 209, which is conducive to ensuring the stability during the limit. The first-level lifting column 501 is arranged on both sides of the outer shell 201, and the bottom of the first-level lifting column 501 is connected with a steering shaft 502, which is convenient for providing lifting adjustment and rotation. The bottom of the steering shaft 502 is connected with a bottom support sleeve seat 503, and the bottom of the bottom support sleeve seat 503 is internally provided with a moving wheel frame 505 and is connected to the second-level lifting column 5 04 lifting support, which is beneficial for the process of not needing to move when testing, by pushing the steering shaft 502 and the bottom support sleeve 503 down through the first-level lifting column 501, so that the bottom of the bottom support sleeve 503 is supported on the ground, and then the moving wheel frame 505 is pushed down by the second-level lifting column 504, so that the moving wheel frame 505 is supported on the ground, so that it is convenient to move the entire device by pushing the outside of the outer shell 201, avoiding the time and effort caused by carrying by hand.
