Abstract

The invention discloses a static shearing test sample making instrument and a making method of the static shearing test sample making instrument. The static shearing test sample making instrument comprises upper protection rings, internal hexagonal screws, lower protection rings, lower ring cutters, upper ring cutters, a pressing block and a cushion block, and is characterized in that screw holes I are formed in two sides of the cushion block; screw holes II are also formed in two sides of the lower protection rings, and the central distances of the screw holes II are the same as those of the screw holes I; the lower ring cutters and the upper ring cutters are arranged below and above the inner sides of the upper protection rings and the lower protection rings. The static shearing test sample making instrument has incomparable advantages in the sample making precision and the test operation and has the outstanding advantages of simplicity in operation, high sample making efficiency and high precision.

Description

technical field [0001] The invention belongs to the field of soil mechanical performance testing in the discipline of civil engineering, and in particular relates to a static pressure shear sample preparation instrument and a preparation method thereof. Background technique [0002] According to the soil engineering test method standard (GB / T50123-1999), when the disturbed soil is sampled, the sample hitting method and the sample pressing method are generally used. These two methods have many disadvantages: 1. The density accuracy cannot be achieved. The requirements of the test; 2. Sampling does not guarantee a success once. Even if it is successful once, a ring knife sample will consume a lot of soil, which increases the workload of crushing the soil in the early stage; 3. The test process is time-consuming, and making a The ring knife sample takes about half an hour. Generally, the requirements for geotechnical experiments are not high, and it does not take much time to ...
