An air pump is fixedly installed on the inner bottom wall of the base plate, and the air inlet end of the air pump penetrates the base plate and extends to the back of the base plate; the road thickness detection device for highway engineering can drive the forward and reverse motors to adjust up and down by providing the power provided by the electric push rods to cooperate with the sliding frame, and then can cooperate with the spiral drill bit to drill holes in the road surface, without the need for the staff to manually support the drilling equipment, the verticality and quality of the drilling can be guaranteed, which saves the labor intensity of the staff and ensures the drilling effect, but the patent still has the following problems in actual use:

[0004] The above-mentioned device still needs to drill through the concrete layer when drilling, and ensure that the measured drilling depth is greater than or equal to the thickness of the road by observing whether the impurities automatically cleaned out are concrete or soil.

As a result, in subsequent measurements, when the ruler is completely in contact with the bottom of the hole, it is impossible to estimate the error in the thickness of the soil layer contained in the measured data, and the accuracy and credibility of the obtained data are low. In addition, the above-mentioned device also needs to move the equipment after drilling, and then use the ruler to measure an inaccurate data. The operation is complicated and the cost performance is low.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows: the road thickness detection device for highway engineering, by using the rotation characteristics of the threaded rod, can determine the feedback force change within one circle by the depth error generated when the rotation resistance of the rotating handle changes suddenly, and finally makes the measurement error within a controllable and knowable range, saves detection time by estimating high-precision data, and when high-precision depth measurement is required, after cleaning the soil at the bottom of the concrete column, the concrete column pushed out of the rotating cylinder is placed on the lifting plate, and then the depth scale is compared, so that the height of the concrete column can be directly and accurately measured, and then the thickness of the road is accurately measured. The specific contents are as follows:

[0017] 1. The extension shaft rotates by rotating the handle, and then the two threaded rods drive the threaded sleeve to move vertically, and then the connecting plate drives the rotating column to descend, and then the rotating cylinder is slowly inserted into the road. As the concrete hinders the rotation of the handle, resistance is encountered. When the resistance changes suddenly when the handle is rotated, the thickness of the concrete pavement with errors but small errors can be directly obtained through the indicator block and the depth scale, so that the general road condition of the road surface can be obtained through multi-point measurement, avoiding the complex operation of drilling, cleaning the hole, and finally inserting the ruler to measure. In addition, due to the manual rotation of the threaded rod, the threaded rod needs to be rotated many times before the threaded sleeve descends a short distance, which leads to the depth error caused by the sudden change of the rotation resistance. When the handle is rotated by hand, the feedback force change can be determined within one circle, and finally the measurement error is within a controllable and knowable range, saving detection time through the estimated high-precision data;

[0018] 2. The discharging sleeve allows the movable groove to slide outside the rotating cylinder, so that the pushing cross plate pushes out the concrete column inside the rotating cylinder, automatically cleaning the rotating cylinder for the next use. At the same time, when high-precision depth measurement is required, the soil at the bottom of the concrete column is cleaned off, and the concrete column pushed out of the rotating cylinder is placed on the lifting plate, and then the depth scale is compared, so that the height of the concrete column can be directly and accurately measured, and then the thickness of the road can be accurately measured.

[0034] Working principle: Before using this road engineering pavement thickness detection device, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 5 As shown, first push the device to the target area, then start the drive motor 201 to make the connecting shaft 202 rotate through the connecting head 203, the sliding column 204 and the connecting pad 205 to make the rotating column 206 rotate, so that the rotating cylinder 219 rotates, and then rotate the handle 224 to make the extension shaft 207 rotate, and let the connecting wheel 208 drive the transmission belt 209 to rotate, so that the two threaded rods 210 drive the threaded sleeve 211 to move vertically, and then make the connecting plate 213 drive the rotating column 206 to descend, so that the rotating cylinder 219 is slowly inserted into the road, and the rotation of the handle 224 is resisted by the obstruction of the concrete. When the resistance of the rotating handle 224 changes suddenly, it means that the rotating cylinder 219 passes through the concrete and is inserted into the soil below. At this time, the scale of the depth scale 218 pointed to by the indicator block 216 indicates the depth of the rotation cylinder 219 at this time, and thus the thickness of the concrete pavement with an error but a small error can be directly obtained, thereby obtaining the approximate road condition of the road through multi-point measurement, avoiding the complicated operation of drilling, cleaning the hole, and finally measuring. In addition, due to the manual rotation of the threaded rod 210, the threaded rod 210 needs to be rotated many times before the threaded sleeve 211 descends a short distance, which leads to the depth error caused by the sudden change of the rotation resistance. When the feedback is fed back to the manual rotation of the knob 224, the change of the feedback force can be determined within one circle, and finally the measurement error is within a controllable range.

[0035] When the threaded rod 210 is rotated to make the rotating cylinder 219 rise, the discharge sleeve 221 slides outside the rotating cylinder 219 through the moving groove 220, so that the pushing cross plate 222 pushes out the concrete column inside the rotating cylinder 219, automatically cleaning the rotating cylinder 219 for the next use. At the same time, when high-precision depth measurement is required, the soil at the bottom of the concrete column is cleaned off, and the concrete column pushed out of the rotating cylinder 219 is placed on the lifting plate and compared with the depth scale 218, so that the height of the concrete column can be directly and accurately measured, and thus the thickness of the road can be accurately measured;

[0036] By rotating the threaded screw 302, the support pad 303 is pressed against the bottom surface, thereby increasing the stability of the device during operation.
