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 fixing device, the top of the fixing device is provided with a frame head, and the side of the fixing device is provided with an upper supporting device; through an angle measuring device, surveyors and mappers can clearly observe the The opening angle of the outriggers is convenient for surveyors to control the opening angles of the three outriggers in a consistent manner, which helps to reduce surveying and mapping errors and improves the accuracy of construction project cost estimation. The outriggers are fixed by the angle limit device , so that the opening angle of the outrigger is fixed, and the opening angle of the outrigger will not change during the process of centering, leveling and surveying, which increases the stability of the device. Through the cooperation of the clamping device and the adjusting device, it is convenient Surveyors fine-tune the length of outriggers, which is less difficult to operate, reduces the error rate of adjustment, shortens the time spent on centering and leveling work, speeds up surveying and mapping, increases work efficiency, speeds up the process of the project, and improves the practicability of the device.

Description

technical field [0001] The invention relates to the field of construction engineering cost on-site surveying and mapping devices, and more specifically, relates to a construction engineering cost on-site surveying and mapping device. Background technique [0002] The construction cost refers to the construction cost of the project, that is, all the fixed asset investment expenses expected to be paid or actually paid for the construction of a project. These expenses mainly include equipment and tool purchase fees, construction engineering and installation engineering fees, and other construction costs etc. Before estimating the construction project cost, it is necessary to use the construction project cost on-site surveying and mapping device to survey and map the site and measure the terrain, so as to estimate the construction project cost more accurately. The existing construction project cost on-site surveying and mapping device consists of a frame head and a tripod The tr...

Problems solved by technology

[0005] In view of the actual use of the existing construction cost on-site surveying and mapping devices in the prior art, the opening angles of the three outriggers are completely controlled by the experience of the surveying and mapping personnel, and it is easy to make the opening angles of the three outriggers inconsistent, resulting in surveying and mapping. The error is large, and in the process of centering and leveling, the amount of adjustment to the length of the outriggers is relatively small, which requires surveyors and mapping personnel to have the ability to use skillfully, the operation is difficult, and it is easy to make adjustment errors, resulting in centering and leveling The time spent on work is relatively long, the surveying and mapping speed is slow, the work efficiency is low, and the process of the project is slowed down. The purpose of the present invention is to provide a construction project cost on-site surveying and mapping device, which can well solve the problems proposed in the background technology. question
