Fixed-point surveying and mapping device for surface movement and deformation in ecological restoration

According to the technical scheme, the fixed-point surveying and mapping device is characterized in that a cleaning structure is arranged and used for solving the problem that soil attached to the surface of a probe pipe is inconvenient to clean, and an installation structure is arranged and used for solving the problem that a drill bit is inconvenient to replace after being abraded; a convex sliding plate slides into a sliding groove, limiting and fixing after sliding of the sliding plate are achieved through cooperation of a fixing bolt and a bolt hole, then the probe pipe slides relative to a sponge sleeve and an elastic scraping hopper through vertical sliding of a threaded rod, soil and other impurities on the surface of the probe pipe are scraped and cleaned, and automatic cleaning is achieved; the practicability is improved; through clamping of the clamping block and the clamping groove, preliminary installation of the threaded rod and the drill bit is achieved, the elastic force of the installation sp
