On-site surveying and mapping device for construction project cost

Abstract

The invention discloses an on-site surveying and mapping device for construction project cost, which comprises a handrail board, a drive chamber is arranged inside the handrail board, a drive shaft extending up and down is connected to the inner wall of the top end of the drive chamber in rotational fit, and the upper end of the drive shaft is provided with The shielding device is located on the upper side of the armrest board. The surveying and mapping device uses expandable protection to extend the life of the main components of the surveying and mapping device. The driving shaft is provided with a driving gear located in the driving chamber. There are left-right symmetrical fine-tuning sliders, and the fine-tuning sliders are fixedly connected with a crossbeam, and the upper end surface of the crossbeam is fixedly connected with a motor that is dynamically connected with the drive shaft; the present invention has a simple structure and is realized by mechanical initial position calibration Accurate measurement also avoids the limitations of electronic equipment, and marks the location of the initial measurement for subsequent inspection, and uses the shielding structure to realize the protection function.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping tools, in particular to an on-site surveying and mapping device for construction engineering costs. Background technique [0002] The direct written meaning of project cost is the cost of project construction, and its three elements are quantity, calculation and price. The most important thing after the three is measurement. There are many traditional measurement tools, but most of them need to calibrate and zero the initial levelness and vertical end during on-site surveying and mapping. Generally, users are required to collect and collect surrounding things, but in the wild, these conditions do not exist, and the user's own operating skills are required to adjust. This will result in inaccurate measurement data. Although there is an intervention adjustment of electronic sensing equipment, the limitation of electronic equipment is large and the cost is expensive. Moreover, the m...

This will result in inaccurate measurement data

Although there is an intervention adjustment of electronic sensing equipment, due to the limitations of electronic equipment and the high cost

Moreover, the measurement of urban road sections will cause vibrations on the ground due to the traffic of vehicles, which will also cause deviations in the measurement data.
