Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a construction engineering cost on-site surveying and mapping device. Background Art

[0002] Engineering refers to the process of transforming an existing entity into a man-made product with expected use value through an organized group of people, based on a set of conceived goals and applying relevant scientific knowledge and technical means. In the on-site survey and cost assessment of construction projects, it is necessary to use surveying instruments to survey the project site. Surveying and mapping is the measurement and drawing of the site. Surveying and mapping devices are usually used to measure the site. At present, some surveying equipment is generally placed on a tripod support frame to form a stable working platform.

[0003] However, in actual use, the opening angles of the three legs of some surveying and mapping devices are completely controlled by the experience of the surveying and mapping personnel, which may easily lead to inconsistent opening angles of the three legs, resulting in large surveying and mapping errors. At the same time, the bottom of the tripod support frame is generally sharp, which may easily pierce the staff during transportation or handling and cause accidental injuries. For this reason, we propose a construction project cost on-site surveying and mapping device to solve the above problems. Utility Model Content
