1) the measurement accuracy is low, and the error is very large by adopting a steel ruler or a depth gauge for manual reading.
2) The measurement efficiency is low, only manual reading and manual recording can be passed, and a large amount of labor cost is consumed in the test.
3) The cross section ruler is an integral part, the length of the cross section ruler is more than 3.5m, and the cross section ruler cannot be disassembled and is inconvenient to carry.
Although the vehicle-mounted laser cross section instrument has high test precision, high automation degree and high test efficiency, the road surface can be tested in the walking process of the test vehicle, and the vehicle-mounted laser cross section instrument is more suitable for testing large projects of engineering quantity. The vehicle-mounted laser cross section instrument has the following defects:
