Description

Technical Field

[0001] The invention relates to the technical field of traffic engineering, and in particular to a detection device used for traffic engineering supervision. Background Art

[0002] Transportation engineering includes railway engineering, water transport engineering, highway engineering, etc., among which highway engineering refers to the survey, measurement, design, construction, maintenance, and management of highway structures. In the process of highway engineering construction, it is necessary to detect and measure the thickness of each structural layer of the highway. The pit digging method is a common method for detecting the thickness of each structural layer of the highway. The pit digging method requires the use of tools such as pickaxes, shovels, and chisels to dig the road surface until the bottom of the current layer is dug, and then the bottom of the pit is cleaned with a brush. Confirm that the bottom of the pit is the top surface of the next layer, and then use a steel ruler to measure. However, when measuring, it often happens that the measuring device cannot maintain the levelness due to the uneven ground, which leads to abnormal measurement data and affects the accuracy of the measurement. In addition, the small stones inside the pit will also interfere with the accuracy of the measurement data.

[0003] Announcement No. CN 217303801 U discloses a detection device for traffic engineering supervision. By installing an adjustment mechanism, the horizontality during measurement can be adjusted so that the measuring rod and the bottom of the pit are in a vertical state, avoiding abnormal measurement data due to uneven ground during measurement, and effectively improving the accuracy of the measurement data. By installing an obstacle-breaking head, the stones inside the pit can be squeezed and pushed, avoiding the stones from obstructing the measuring rod during measurement and affecting the measurement effect, further improving the measurement accuracy. At the same time, by installing an extrusion rod, the obstacle-breaking head can have a certain degree of mobility when cleaning the stones, which is convenient for the obstacle-breaking head to clean the stones. By installing an extrusion spring, the obstacle-breaking head can have a certain degree of elasticity during extrusion, and the stones can be pushed and cleaned more thoroughly. However, the patent still has the following problems in actual use: Although the detection device for traffic engineering supervision can adjust the horizontality during measurement by installing an adjustment mechanism so that the measuring rod and the bottom of the pothole are in a vertical state, thus avoiding abnormal measurement data due to uneven ground during measurement, it is necessary to dig or drill holes in the detection area in advance when conducting detection, which is not only cumbersome to operate but also inconvenient to control the thickness of the excavation. Once the depth of the excavation exceeds the thickness of the various structural layers of the highway, it will affect the accuracy of the detection data.
