Problems solved by technology

[0003] Geological prospecting is the survey and research activities of geological exploration and detection through various means and methods, determining the appropriate bearing layer, determining the foundation type and calculating the foundation parameters according to the foundation bearing capacity of the bearing layer. Excavate pits, grooves, wells, and holes for observation and detection, and measure the distance between the pits, which is convenient for making geological structure models. Because the bottom surface is usually in a state of unevenness, it is difficult to use tools such as tape measure to measure. The existing distance measurement methods mainly Theodolite and range finder are used to measure. This method of measurement is ...
