Description

Technical Field

[0001] The utility model relates to the technical field of highway quality detection, in particular to a flatness detection device for highway engineering quality detection. Background Art

[0002] Road surface smoothness refers to the deviation value of the longitudinal convexity of the road surface. It is one of the important technical indicators for evaluating road quality. It is related to driving safety, comfort, the impact force that the road surface can withstand and its service life. Uneven road surface will increase driving resistance and cause additional vibration to the vehicle. Therefore, the road surface smoothness needs to be tested before the highway is put into use.

[0003] Chinese patent with announcement number CN216846061U discloses a flatness detection device for highway engineering quality inspection, including a transport platform, wherein two through slots are provided in the middle of the transport platform, and guide rails are fixedly connected to both ends of the two through slots. The advantages of the utility model are that: locking assemblies that can move up and down are arranged inside the two through grooves, and the four guide rails are grouped in pairs, and the four bolts are loosened, and then a number of measuring columns automatically fall onto the road surface. The height difference between the top surfaces of the several measuring columns is convenient for intuitively displaying the flatness of the road surface. After the measurement is completed, the two bolts are tightened, one of the locking assemblies is lifted, and a locking assembly is limited by a block, so that the user can look straight at the scale line and read the flatness of the road surface. The two locking assemblies can measure and read respectively, thereby improving the detection efficiency. At the same time, the overall structure of the device is simple and easy for users to operate. However, the above patent is not only inconvenient for the staff to observe the detection results intuitively, but also the sliding of the measuring column will cause a certain impact on the detection results, reducing the practicability of the device. Therefore, a person skilled in the art provides a flatness detection device for highway engineering quality detection to solve the problems raised in the above background technology.
