Lifting type undisturbed soil triaxial sample preparation device

Abstract

The invention discloses a lifting type undisturbed soil triaxial sample preparation device, which belongs to the field of indoor geotechnical testing of civil engineering discipline, and comprises a supporting mechanism, a lifting mechanism, a cutting mechanism, a limiting mechanism and a sample bearing mechanism; the invention adopts a hydraulic lifting table to drive the lifting of a soil sample, and replaces manual cutting by a circular rotatable cutting blade; due to the use of the circular cutting blade, the soil can be directly cut into a cylindrical sample during a cutting process. In this way, according to the soil sample data, the hardness of the soil sample is determined, and different cutting speeds are determined; the soil sample can be raised by the hydraulic lifting platform,and the gradually raised soil sample is cut by the rotation of the cutting blade to complete a preliminary production of a triaxial sample. According to the lifting type undisturbed soil triaxial sample preparation device, the problems that existing sample preparation devices have complicated operation steps in a sample preparation process, are greatly affected by the proficiency of a sample preparation operator, have a low sample preparation efficiency, have a large disturbance to the soil sample during the sample preparation process, have a low success rate of the sample preparation and thelike are solved.

Description

technical field [0001] The application relates to a lift-type undisturbed soil triaxial sample preparation device, which belongs to the technical field of indoor geotechnical testing in the discipline of civil engineering. Background technique [0002] At present, with the continuous development of the construction industry, it is necessary to determine the mechanical properties of the undisturbed soil at the beginning of the project. Triaxial mechanical tests are usually used to provide information for the design of building structures. When the undisturbed soil is tested for triaxial mechanical tests, the cylindrical soil body with a diameter of 150 mm and a height of 200 mm should be made into a standard sample. The standard sample is usually a cylinder with a diameter of 39.1 mm and a height of 80 mm; To disturb the sample, appropriate sample preparation equipment, commonly called a soil cutter or sampler, must be used. At present, although the sample preparation device...
