The present invention relates to the technical field of
measuring equipment, and discloses a device for detecting
karst caves in rotary-drilled piles using
laser radar, including a positioning frame and a fixing frame, the bottoms of the two groups of fixing frames are plugged into the tops of the positioning frames, a driving motor is installed on the fixing frame on the rear side, a same rotating shaft is installed between the two fixing frames, the rear end of the rotating shaft is fixedly connected to the output shaft of the driving motor, a winding wheel is fixedly connected to the outside of the rotating shaft, and a pulling
rope with scales is wound inside the winding wheel. The device for detecting
karst caves in rotary-drilled piles using
laser radar and its use method, when the device reaches the bottom of the hole, slowly lift the device, turn off the device and stop scanning, the
laser radar sensor is selected from mature sensors currently on the market, the entire device is mature in technology, strong in
operability, simple to make, convenient and quick to install, accurate in positioning, can provide accurate information for solving
karst cave solutions, safe and reliable.
