Description

Technical Field

[0001] This utility model belongs to the field of geodetic surveying and engineering surveying technology, and specifically relates to a surveying tool that facilitates general surveying and burial selection. Background Technology

[0002] The dimensions of the protective mat at national control points are typically 0.6m × 0.6m × 0.15m, with a calculated volume of 0.054m³. 3 Based on the standard concrete density of 2400 kg / m³, the theoretical weight of the concrete in this retaining wall is approximately: Wconcrete = 0.054 × 2400 = 129.6 kg. It should be noted that this weight is a theoretical value excluding the additional weight of the reinforcing steel frame; the actual weight may be slightly higher.

[0003] The weight of a single protective plate exceeds the carrying capacity of an average adult male. In the traditional operation mode of national control point survey and selection, it is necessary to use tools such as pry bars to assist in moving it, and usually multiple operators are required to work together to complete the moving operation.

[0004] Therefore, it is necessary to design a surveying tool that facilitates surveying and burial, thereby effectively addressing the pain points of high labor intensity and safety risks associated with manual handling of survey markers in traditional work methods. Tool-based design reduces the physical burden on field workers and simultaneously minimizes potential safety hazards caused by manual handling; modular connection features enable rapid installation and disassembly, shortening preparation time and improving the overall construction efficiency of surveying and burial markers.
