Description

Technical Field

[0001] The invention relates to the technical field of engineering surveying and mapping, and in particular to a multifunctional benchmark for engineering surveying. Background Art

[0002] When conducting engineering surveying, it is necessary to first install a prism on the benchmark, and then insert the benchmark into a suitable position so that there is no obstruction between the benchmark and the total station.

[0035] The specific usage and function of this embodiment are as follows: when in use, first rotate the protective mounting sleeve 3 to make the protective mounting sleeve 3 move upward along the position adjusting thread 101 until the position fixing rod 2 is exposed.
