Description

TECHNICAL FIELD

[0001] The utility model relates to highway detection technical field, especially a kind of highway collapse test detector. BACKGROUND

[0002] With the rapid development of transportation industry, as one of the most important traffic infrastructure, the safety and stability of highway are concerned. Under the influence of vehicle load, natural environment erosion (such as rainwater scouring, thermal expansion and contraction caused by temperature change) and underground geological condition change (such as groundwater level fluctuation, soil creep) and other factors, pavement collapse problem occurs occasionally.

[0003] The patent with publication number CN220908350U discloses a highway foundation collapse monitoring device. During use, the staff controls the motor through the operation panel to adjust the electric push rod to the horizontal state, then controls the electric push rod to adjust the position of the sleeve ring, adjusts the height of the sleeve ring through the telescopic rod, and then fixes it through the locking bolt after adjustment. Then insert the detection rod into the sleeve ring to make its bottom end contact with the road surface, then move the base to the edge of the road surface, and the detection rod is in the middle position of the road surface. The collapse of the roadbed is monitored by moving the push frame pushing device. During the detection process, the ball is always in contact with the road surface. When the road surface collapses, the detection rod will move downward along the collapse depth of the road surface. At this time, the depth of the roadbed collapse can be understood by observing the monitoring screen of the scale value of the observation camera. However, the device has the following defects during use. Although the electric push rod can move the detection rod to a certain extent, it is difficult to achieve full coverage for wider road surface or area that needs large-area continuous monitoring. For example, on a multi-lane highway, the detection rod of the device may not be able to detect the collapse of all lanes at one time, and the device position needs to be adjusted multiple times, which is complicated and inefficient, and potential collapse hidden danger areas are easily missed.

[0004] Therefore, how to increase the detection range of the device becomes a technical problem that needs to be solved by those skilled in the art. UTILITY MODEL CONTENT
