What Are The Commonly Used Measurement Methods For Rail Shoulder Difference?

In the process of railway construction and maintenance, the height and level of the track are very important parameters. Among them, the rail shoulder difference is an important factor affecting railway driving safety. Therefore, in order to ensure the safety of railway traffic, it is necessary to measure the rail shoulder difference. What are the commonly used measurement methods for rail shoulder difference?

1. Direct measurement method. The direct measurement method is a method based on the line of sight measurement principle. The surveyor needs to stand next to the track and measure the rail shoulder difference by measuring the intersection point of the vertical line and the track. This method is simple to operate and does not require much equipment, but the error is large.

2. Laser measurement method. The laser measurement method is a relatively accurate measurement method. The laser instrument is used to measure the track height difference on both sides of the track to calculate the derailment shoulder difference. This method can be accurate to the millimeter level, but requires specialized equipment and qualified personnel to operate.

3. Electronic measurement method. The electronic measurement method is a measurement method based on electronic instruments and sensors. It can measure the rail shoulder difference at multiple points at one time with a small error. However, it requires professional equipment and staff to operate, and the cost is relatively high.

Railway shoulder difference measurement is very important for railway safety and maintenance, and requires accurate and reliable measurement methods. Various measurement methods have their own advantages and disadvantages, and they need to be selected and applied based on the actual situation. At the same time, you need to pay attention to safety when making measurements to ensure that the measurement results are accurate and reliable.
