Problems solved by technology

However, when using the ring knife to sample in the sample preparation cylinder, it will often cause disturbance to the lower soil, and even crack the lower soil, so that the lower soil can no longer be sampled with the ring knife
This will not only waste the amount of soil, but also take a lot of time to prepare prefabricated soil samples, so it is urgent to improve the existing device

Abstract

The invention discloses a ring knife sample prefabricating device for undisturbed soil and a working method. The device of the invention is capable of producing a prefabricated soil sample by the following steps of: fixing a segmented sleeve on the L-shaped base of a clamping device; then clamping and fixing the segmented sleeve by a horizontal restraining device; and finally, processing the segmented sleeve. The device is simple in manufacture, low in cost, and convenient in operation. The process for preparing a prefabricated sample is simple, efficient, and fast.

Description

technical field [0001] The invention belongs to the field of civil engineering experiment research, and in particular relates to a ring knife sample prefabrication device and working method of undisturbed soil. Background technique [0002] In order to carry out the geotechnical characteristic experiment on the undisturbed soil in the process of engineering and laboratory experiment, the most critical point is to prepare the ring knife sample. Under normal circumstances, it is necessary to put the sample soil into the soil sampling box, and then open it in the indoor laboratory. With the cutting cooperation of the soil cutter, use the ring knife to directly act on the entire soil sample to obtain the sample. However, when the ring knife is used to sample in the sample preparation cylinder, the lower soil mass is often disturbed, and even the lower soil mass is cracked, so that the lower soil mass can no longer be sampled with the ring knife. This will not only waste the amo...
