Description

Technical Field

[0001] The utility model belongs to the technical field of surveying and mapping benchmarks, and in particular relates to an assembled benchmark for real estate surveying and mapping. Background Art

[0002] In real life, people need to use surveying equipment for real estate surveying, among which surveying poles are one kind of surveying equipment. Surveying poles refer to measuring tools in the shape of poles with red and white paint on them. They are mainly used to indicate measuring points. Existing poles generally use wooden poles. During use, the poles are inserted into the measuring points so that the surveyors can accurately observe the measuring points. In the process of surveying, a staff member is generally required to hold the pole at the surveying point to keep it stable. Traditional poles are generally long and inconvenient to carry. In addition, during the use of the poles, the position of the poles may shift, affecting the accuracy of surveying. In addition, a staff member is required to hold the pole all the time during the surveying process, which consumes the manpower of the staff. Based on this, we propose a pole that is easy to carry and easy to use. Utility Model Content
