[0001] The utility model relates to the technical field of survey equipment, in particular to a construction engineering survey equipment. Background Art

[0002] Construction sites usually require surveys before construction. The purpose of the survey is to evaluate land and environmental conditions, determine the feasibility of construction, and understand possible risks and challenges. This includes considering factors such as topography, soil type, geological conditions, and hydrological conditions. Through surveys, appropriate construction plans and measures can be formulated to ensure smooth construction and minimize possible problems and delays; construction sites usually require drilling surveys before construction.
