Abstract
Description
Technical Field
[0001] This utility model is a civil engineering surveying and setting-out device, belonging to the field of surveying tool technology. Background Technology
[0002] Civil engineering generally refers to civil engineering projects, which encompass the planning, construction, and maintenance of all infrastructure related to water, soil, and culture. In reality, typical civil engineering projects include housing, roads, waterworks, canals, flood control, and transportation. Before civil engineering projects commence, it is generally necessary to use surveying equipment to measure the construction site. Preliminary work for building construction includes clearing and leveling the site and surveying and setting out lines. Based on the architectural design drawings, the construction is positioned. After the building positioning stakes are set, the surveyors from the construction unit, the site supervisor, and the project manager jointly participate in the surveying and setting out work. During the setting out process, construction personnel need to measure the construction site.
[0003] When encountering muddy or wet ground, the rope will be covered with mud or clay after laying out the line. Since the existing line laying equipment lacks a cleaning mechanism, the mud and dirt on the rope will increase its weight, making it more difficult to reel in and out the rope when laying out the line repeatedly.
