Problems solved by technology

Traditional leveling devices and corresponding operating methods have the following disadvantages: (1) Three-point configuration, asynchronous observation, and low measurement efficiency
Because it takes a lot of energy and time for the surveyors to realize the reasonable configuration of the positions between the three points of the leveling instrument and the leveling rod in a complex terrain environment, and at the same time, the asynchronous observation of readings according to the scales respectively increases the observation time, which affects the In addition, when encountering complex terrain environments such as steep slopes, potholes, ponds, ditches, ravines, rivers, and mountainous areas, it is often impossible to set up the level in the middle of the two leveling rods, resulting in the failure of leveling. implement
(2) Single observation system, low measurement reliability
However, the above-mentioned patent application still has the following deficiencies: (1) The tripod, the leveling rod and the auxiliary ruler pad are set separately. After moving the station, they all need to be combined before leveling. Moreover, it will also affect the accuracy of continuous observation, and even damage the leveling rod during the combination process; (2) When using a three-legged tripod, it will form a four-point landing with the leveling rod, which is difficult to balance and stably place; when the ground height difference is large, After raising or lowering the height of the height signal detector (level), the surveyor cannot aim and focus through the eyepiece due to physical factors; after the tripod is installed, the ruler cannot rotate relative to the tripod (ground), straighten and aim. The steps are difficult to coordinate and cannot work

Description

technical field [0001] The invention belongs to the technical field of geodetic and engineering surveying, and in particular relates to a rapid leveling device integrated with a ruler and instrument, which can effectively improve the working efficiency and reliability of leveling without being restricted by the terrain environment. Background technique [0002] A traditional level measuring device is composed of a level and two leveling rods. When measuring, first place the two leveling rods on the ground at points A and B respectively, and then set the leveling instrument at the middle position of the two points A and B. In order to ensure the measurement accuracy, the horizontal distance between the leveling device and the two leveling rods is generally required. Equal or approximately equal. Use the horizontal line of sight of the leveling instrument to read the elevation values ​​of the two leveling rods respectively. The difference between the measured elevation values...
