On-site surveying and mapping device for construction project cost

Abstract

The invention discloses an on-spot mapping device for construction project costs. The device comprises a protective device, wherein a supporting device is arranged on the bottom surface of the protective device; through a fixing device, a mapping instrument can be conveniently fixed and disassembled by mapping personnel, so that the mapping instrument can be maintained; through a suspension device, the mapping personnel can quickly and accurately carry out centering operation, so that the mapping speed is increased, and thus the accuracy of mapping is further improved; through the cooperationof the protective device, a clamping device, the suspension device and a lifting device, the mapping instrument can pop out from the interior of the protective device and be engaged in the mapping work; through the cooperation of the clamping device and the lifting device, the mapping instrument can be retightened to the interior of the protective device by directly pressing a sealing plug after the mapping instrument is used by the mapping personnel, an operation process is simple and rapid, very convenient to implement, time-saving and labor-saving, the working efficiency is improved, the mapping speed is further increased, and the practicability of the on-spot mapping device for the construction project costs is improved.

Description

technical field [0001] The invention relates to the field of construction engineering cost on-site surveying and mapping equipment, more specifically, relates to a construction engineering cost on-site surveying and mapping device. Background technique [0002] The project cost refers to the construction price of the project, which refers to the sum of all the expected or actual costs required to complete the construction of a project. From the perspective of the owner or investor, the project cost refers to the construction cost of the project, which is the construction cost. All fixed asset investment expenses that are expected to be paid or actually paid for a project, these expenses mainly include equipment and tool purchase expenses, construction engineering and installation engineering expenses, other project construction expenses, reserve expenses, interest during the construction period, and adjustment of fixed asset investment direction Taxes, etc., defined from the...

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 the surveying and mapping instrument is directly bolted on the tripod and is exposed. After a single use, in order to prevent the surveying and mapping instrument from being damaged during transportation, people usually separate the surveying and mapping instrument from the tripod and install the surveying and mapping instrument. Carrying in a suitcase, the operation process is cumbersome, very inconvenient, time-consuming and laborious, low work efficiency, and slow surveying and mapping speed. proposed question
