Abstract

The invention discloses a gradiograph salvaging device. The gradiograph salvaging device comprises a horn-shaped salvaging head. The big head end of the horn-shaped salvaging head is arranged downwards, the outer wall of the small head end of the horn-shaped salvaging head is connected with at least one steel bar connecting rod, and the other ends of the steel bar connecting rods are connected with steel pipes. A notch is formed in the horn-shaped salvaging head. During using, the big head end of the salvaging head is downwards inserted into a surveying pipe, and a salvaging instrument clampedin the surveying pipe is salvaged; the horn-shaped salvaging head with the notch is adopted, and a guide wheel of a gradiograph can enter the horn-shaped salvaging head; and meanwhile, due to the fact that the minimum inner diameter of the horn-shaped salvaging head is slightly larger than the diameter of the gradiograph, the guide wheel of the gradiograph can penetrate the salvaging head, and accordingly it is guaranteed that the problem of guide wheel clamping or lower guide wheel clamping in the salvaging process can be solved.

Description

technical field [0001] The invention belongs to a salvage device for geotechnical engineering measuring instruments, in particular to an inclinometer salvage device for salvaging an inclinometer stuck in an inclinometer pipe and a using method thereof. Background technique [0002] An important monitoring item in the field of geotechnical engineering monitoring is the horizontal displacement of deep soil. During the construction of foundation pits, docks, bank slopes, foundations, dams, etc., the monitoring of horizontal displacement of deep soil is a must-test item. . [0003] Inclinometers are divided into portable inclinometers and fixed inclinometers. Portable inclinometers are divided into portable vertical inclinometers and portable horizontal inclinometers. Fixed inclinometers are divided into single-axis and dual-axis inclinometers. At present, portable inclinometers are the most widely used. [0004] See attached figure 1 and 2 , the inclinometer tube (a) is usu...
