Problems solved by technology
[0005] In order to make up for the deficiencies of the existing technology, the existing detection trolley does not have a special marking device, and it is impossible to find small concave areas in time only by the detection personnel following behind, so that the detection efficiency of road surface depressions is not high. The present invention proposes A road surface depression detection device for municipal engineering

The invention discloses a pavement depression detection device for municipal engineering. The pavement depression detection device comprises a vehicle body and a detection unit, a working box is fixedly connected to the bottom of the vehicle body; the detection unit is arranged in the working box; the detection unit comprises a positioning mechanism and a marking mechanism; the positioning mechanism comprises a positioning wheel, a supporting rod, an upper contact, a lower contact, a first fixing plate, a damping assembly and a limiting assembly. The positioning wheel is arranged at the bottom of the supporting rod; the top end of the supporting rod penetrates through the inner wall of the working box and is arranged below the first fixing plate. The upper contact is fixedly connected to the bottom of the first fixing plate. By arranging the detection unit, the vehicle body linearly moves on the urban road, and the positioning mechanism is matched with the marking mechanism, so that the vehicle body moves while drawing a straight line by using lime powder, and when the vehicle body encounters a sunken place, an upper contact and a lower contact are disconnected, so that the marking assembly stops drawing the line, and detection personnel can conveniently find the sunken position of the road surface in time; and related data are recorded, so that the pavement depression detection efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of building construction detection equipment, in particular to a road surface depression detection device for municipal engineering. Background technique [0002] Municipal engineering includes urban roads, bridges, water supply and drainage, sewage treatment, and gardens. The smoothness of the road surface is one of the main technical indicators for evaluating the quality of the road surface. It is related to the safety and comfort of driving, the impact force on the road surface and the service life. The uneven road surface will increase the driving resistance and cause additional vibration for the vehicle. In urban roads, in order to maintain the road surface better, it is necessary to regularly inspect the road surface for sags and find the sags in time. According to the actual situation, give Come up with a reasonable fix. [0003] At present, there are many methods for measuring pavement sag, among wh...
