Technical Field

[0001] The utility model relates to the technical field of highway construction detection equipment, in particular to a levelness detection instrument for highway construction. Background Art

[0002] The road surface levelness is one of the important indicators of road construction quality and service level. Uneven road surface will increase driving resistance and cause additional vibration to vehicles. This vibration will cause driving bumps, affecting driving speed and safety, driving stability and passenger comfort. At the same time, the vibration will also exert impact force on the road surface, thereby aggravating the damage to the road surface and the car and the wear of the tires. Uneven road surface will accumulate rainwater and accelerate the destruction of the road surface. Therefore, the detection and evaluation of levelness is a very important part of highway construction and maintenance.

[0003] Existing level detectors for highway construction are generally fixed structures, the device itself is large in size, and cannot be folded, which is not convenient for storage box transportation, affecting the performance of the device and reducing the practicality of the device.

If the road surface levelness meets the requirements, the infrared rays emitted by the infrared transmitter 11 pass through the through holes 10 on the multiple limit blocks 9 in sequence and are received by the infrared receiver 12, and the alarm 13 does not sound an alarm. When the road surface levelness does not meet the requirements, a certain slide bar 6 rises or falls, so that the infrared rays emitted by the infrared transmitter 11 are blocked by the limit block 9 on the slide bar 6 and cannot be received by the infrared receiver 12, then the alarm 13 sounds an alarm, indicating that the road surface is not level, and the level can be measured by the scale 14.
