Novel night leveling rod

Technical Field

The utility model belongs to the technical field of the engineering survey, relate to the levelling rod, in particular to novel night levelling rod.

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 gauge is arranged between two points on the ground, a leveling staff erected on the two points is observed, and the height difference between the two points is calculated according to the reading on the staff. The elevation of each point is typically determined from the leveling origin or any known elevation point, from station to station along the selected leveling route. Because the measurement precision of leveling measurement is relatively high, the leveling device is widely applied to the fields of engineering measurement, industrial measurement, geodetic measurement and the like.

Currently, levels for practical use are classified into optical levels and electronic levels according to their operating principles. In practice, a large number of measurements are inevitably carried out in a nighttime environment, such as: the method comprises the following steps of in-tunnel water level observation, engineering night construction, and bridge dynamic and static load test, highway settlement observation and the like under the condition that vehicles at night are scarce because the measurement precision is reduced due to vibration generated by the vehicles at daytime. Because the illumination condition often can not reach the requirement of looking through at night, the level observation is completed by the aid of lighting or a flashlight. This requires additional personnel and is not effective. Particularly, the electronic level has high requirement on illumination intensity, and reading cannot be performed under the conditions of low illumination intensity, uneven light or shadow on a bar code ruler.

Therefore, there is a need to provide a new technical solution to overcome the above-mentioned drawbacks.
