However, the water filling method is limited to the length of the pipe. In addition, the method using a level requires an expensive level, which increases the measurement cost and requires skill in handling the level. Further, the leveling of the rail has a large error because it is a visual measurement, and therefore correction calculation is required when the rail has a cant, and an obstacle B such as a weed is present between the rail surface Rb and the electric pole S. Sometimes I can't survey. Further, since it is necessary to bend over and collimate, it is a difficult work and requires skill.
