Abstract

The invention discloses an outer wall cutting device for a soft clay based hollow cylindrical test sample and a use method of the outer wall cutting device. The device comprises an external support, a screw rod, a driving device, a test sample fixing device and a test sample cutting device, wherein the screw rod is arranged in the external support, the bottom end of the screw rod is rotationally supported to a bottom plate, and the upper end of the screw rod is connected with the driving device; the test sample fixing device is connected onto the screw rod and can rotate from top to bottom in the rod axis direction of the screw rod when the screw rod rotates, the test sample cutting device is arranged in the rod axis direction of the screw rod, the screw rod is driven by the driving device to rotate so as to drive the test sample to rotate from top to bottom, and when the test sample passes through the cutting device, the cutting device cuts the outer wall of the test sample. According to the outer wall cutting device, the defects that disturbance to the hollow cylindrical test sample is possibly produced and cutting is not performed in place during manual cutting are overcome, the operation is simple, and uniform cutting molding can be realized once.

Description

technical field [0001] The invention relates to an outer wall cutting device of a soft clay hollow cylindrical sample and a use method thereof. Background technique [0002] As one of the most complex and powerful instruments in indoor geotechnical testing, the hollow cylinder torsional shear instrument has been used more and more at home and abroad. Usually, the outer wall of the soft clay hollow cylinder sample needs to be cut to make a standard Hollow cylindrical specimen. With the continuous increase of experimental research on soft clay hollow cylindrical soil samples, how to stably and conveniently cut the outer wall of soft clay hollow cylindrical samples is of great significance to shorten the test time and ensure the authenticity and reliability of test results. For example, the Chinese patents ZL 200710070117.7 and ZL 201310251375.0 respectively invented the sample preparation methods of the original soft clay and reshaped soft clay hollow cylinder samples, and th...
