Abstract

The invention relates to the technical field of measuring equipment, and further discloses equipment for detecting the karst cave in the rotary excavating pile through the laser radar. The equipment comprises a positioning frame and a fixing frame, the bottoms of the two sets of fixing frames are connected with the top of a positioning frame in an inserted mode. A driving motor is installed on thefixing frame on the rear side, the same rotating shaft is installed between the two fixing frames, the rear end of the rotating shaft is fixedly connected with an output shaft of the driving motor, awire winding wheel is fixedly connected to the outer portion of the rotating shaft, and a pulling rope with scales is wound in the wire winding wheel. In the equipment for detecting a karst cave in arotary excavating pile through a laser radar and a using method thereof, when the device reaches the bottom of a hole, the device is slowly lifted, equipment is shut down, scanning is stopped, a mature sensor on the market at present is selected as a laser radar sensor, the whole equipment is mature in technology, high in operability, easy to manufacture, convenient and rapid to install and accurate in positioning, accurate information can be provided for a karst cave solution, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of measuring equipment, in particular to a device for detecting karst caves in rotary excavation piles using laser radar and a method for using the same. Background technique [0002] In the construction of engineering rotary excavation piles, for the construction area of ​​karst landform, the landform is uneven and the geological conditions are complex. During the process of hole formation, the situation in the hole can be grasped in time, and problems such as karst caves and cracks along the rock can be accurately judged and analyzed. Make targeted treatment plans and measures. [0003] The technical solution of the prior art: in the actual construction process, if there is a risk of hole collapse in caves or rock fissures, it is usually prohibited to manually drill holes to collect information on caves in the holes. The usual practice is to throw a steel ruler around the hole and use a flashlight to meas...
