Description
Technical Field
The utility model relates to a levelling device of levelling rod distance is reported in dynamic display belongs to field leveling technical field.
Background
Leveling, also known as "geometric leveling", is a method of measuring the difference in height between two points on the ground using a level gauge and a leveling rod. A level (English: level) is an instrument for establishing a horizontal sight line to measure the height difference between two points on the ground.
Leveling work is carried out, field observation is greatly influenced by terrain, and the requirement on field observation precision is high. The technical indexes of field observation are taken as example of national second-class leveling: the sight length is less than or equal to 50m, the difference between the front sight distance and the rear sight distance is less than or equal to 1.5 m, and the cumulative difference between the front sight distance and the rear sight distance is less than or equal to 6.0 m; the height of the sight line is more than or equal to 0.5m; station measurement tolerance: the difference of the readings of the two times is less than or equal to 0.4mm, and the difference of the height difference measured by the two times is less than or equal to 0.6 mm. If the front and rear sight distances are not equal in the leveling process, the measurement precision is difficult to guarantee. The larger the difference between the front and rear visual distances is, the larger the measurement error caused by the fact that the instrument has an i angle (an included angle caused by the fact that the sight axis is not parallel to the horizontal axis) is, and the precision of field measurement data is greatly reduced.
And carrying out field leveling measurement, eliminating measurement errors caused by unequal front and rear sight distances in order to ensure that the front and rear sight distances are equal, and ensuring that field measurement data meet the precision requirement. The existing field leveling mainly adopts the following two modes.
The first one is that in leveling work, 3 measuring staff need to be equipped to carry out observation and ruler holding work, 2 measuring staff are additionally equipped to carry out front and rear sight distance measuring work in the leveling process by using a tape measure, a steel ruler or 1 measuring staff by using a hand-push roller type measuring ruler, and the sight distance length is ensured to be less than or equal to 50m, the front and rear sight distance difference is less than or equal to 1.5 m, and the front and rear sight distance accumulation difference is less than or equal to 6.0 m to reach the standard (the requirement of the second-class leveling field operation in China). The measuring method needs 4 to 5 measuring personnel. The labor cost for the measurement work increases. The measuring method needs to frequently measure the distance in the measuring process, the distance measurement takes a large amount of time, and the measuring working efficiency is reduced. The measuring method is limited by external terrains, such as large relief, uneven ditch ridge, incapability of distance measurement or low distance measuring precision.
The second is that in the leveling work, the operator of the instrument measures the distance between the measuring station and the front ruler and the distance between the measuring station and the rear ruler in advance by using the distance measuring function of the menu bar of the electronic level. Or the optical level is used for measuring the front ruler and the rear ruler, reading the reading of the upper thread and the lower thread, calculating the distance from the measuring station to the rear ruler of the front ruler, and commanding the staff holding the ruler to move the ruler back and forth for measurement. The measuring method occupies a large amount of time for measuring the distance, and the working efficiency of measurement is reduced. The measuring method has high requirements on instrument operators and ruler holding personnel, the measuring personnel need to frequently measure and calculate the distance, the ruler holding personnel are instructed to move the ruler back and forth after the distance is checked, and the field observation quality is difficult to guarantee.
