Description

A surveying instrument

Technical Field

The present application relates to the technical field of engineering construction, and in particular to a surveying and mapping instrument.

Background technique

The construction process is inseparable from the project cost, that is, the construction price of the project. The construction project cost refers to all the expenses incurred in the construction project. Its core content is investment estimation, design budget, revised budget, construction drawing budget, project settlement and final settlement, etc. Some project costs in construction projects usually involve leveling, angle measurement, distance measurement, straight line orientation, small area control measurement, large-scale topographic mapping and application, and construction site control measurement. Most measurements require the use of engineering cost surveying instruments.

Patent No. CN218819028U discloses a surveying instrument, which is convenient for installing and fixing the surveying instrument body through the setting of fixing components, and is also convenient for quick removal, and is easy to operate. The setting of the adjustment component can be used to adjust the angle, and after the angle adjustment is completed, it can also be quickly reset to avoid the tediousness of manual reset. The setting of the support component can be used to adjust the height, which is convenient for operators of different heights to use, and can also maintain horizontality, which is conducive to use on uneven ground. The device is easy to install and disassemble, easy to carry and easy to use. However, when adjusting the height of the surveying instrument, it needs to be adjusted multiple times according to the data of the level meter. Not only does it need to reach the appropriate height, but it also needs to be adjusted to a horizontal state. Each adjustment before using the surveying instrument takes a lot of time and energy, and the adjustment efficiency is low.
