On-site surveying and mapping device for construction project cost

Abstract

The present invention relates to the technical field of on-site surveying and mapping devices, in particular to an on-site surveying and mapping device for construction engineering cost, which includes a triangular bracket. platform, and a surveying instrument is fixedly connected to the middle position on the top of the installation platform. When the connection between the tripod and the ground becomes loose, the entire surveying and mapping device will change, and the installation platform will tilt, resulting in a leveling failure. At the same time, the cone will touch the tilt trigger device on the side, and after being sensed by the tilt trigger device, After the tilt trigger device touches the cone, it triggers the rotation of the rotary drive device and activates the warning light at the same time. The rotary drive device rotates on the drive indicator ring and moves with the warning light to warn, reminding the nearby staff to re-level in time to avoid causing damage. Inaccurate surveying and mapping due to failure to check in time is conducive to the accuracy of later construction project costs.

Description

technical field [0001] The invention relates to the field of on-site surveying and mapping devices, in particular to a construction project cost on-site surveying and mapping device. Background technique [0002] Before carrying out large-scale engineering construction, the topographic map must be measured and drawn by surveying and mapping engineers, and other information materials must be provided before decision-making, planning and design can be carried out. The information obtained from on-site surveying and mapping is helpful for construction projects to consider the cost of the project. [0003] Some patent documents related to engineering surveying and mapping are disclosed in the prior art. The Chinese patent application number 201811574229.0 discloses a field surveying and mapping device for construction engineering cost, including a surveying instrument body, a base and a foot installed on the base. It also includes an annular base; the annular base is provided w...

AI Technical Summary

Problems solved by technology

[0004] The existing on-site surveying and mapping device for construction project cost needs to be leveled before use to ensure the accuracy of the measurement. Due to the difference in the geographical environment of the survey, when the connection between the bottom end of the tripod supporting the surveying instrument and the ground becomes loose, the entire The instability of the surveying and mapping device will cause the previous leveling to lose its effect. If the staff cannot be reminded to check in time during work, they will directly record the surveying and mapping, resulting in inaccurate technical data
