Problems solved by technology

[0003] At present, there is no film loading device that can be used in the film loading process of the triaxial test of the dynamic strength of soil. Engineering and scientific research personnel have to set the rubber film on the soil sample with bare hands. Such a free-hand fitting process will easily damage the shape and dynamics of the soil sample. The intensity of the study makes the number of precious soil samples more tense
In addition, such a bare-handed suit process generally requires 2 people to complete, and the speed is relatively slow, which has affected the efficiency of the dynamic strength triaxial test of the whole soil

Abstract

The invention discloses a soil sample membrane loading device for a soil movement triaxial test, comprising a triangular fixing device and a membrane loading device. Divided into soil sample pier, soil sample sleeve, soil sample sleeve lifting rod and rubber membrane pressure ring, the membrane loading device prepares one set of commonly used soil samples with a diameter of 39.10mm and a diameter of 50.00mm; In the prior art, the shape and dynamic strength of the soil are easily damaged when the membrane loading device is used for membrane loading of soil samples, which improves the success rate of soil sample loading membrane, improves the speed of soil sample loading membrane, and reduces labor costs.

Description

technical field [0001] The invention relates to the field of soil dynamic strength triaxial test, in particular to a soil sample film packer for soil dynamic triaxial test. Background technique [0002] The dynamic strength triaxial test of soil refers to preparing undisturbed soil or remodeled soil into a soil sample of a certain size, putting rubber membrane on it and placing it in a true triaxial or false triaxial testing machine. Load value (or confining pressure value, vertical dynamic load value), dynamic load frequency, etc., apply dynamic load to soil sample to obtain the test of soil sample dynamic strength and other dynamic parameters. The dynamic strength triaxial test of soil is widely used in the fields of geology, mining, safety and construction, and is an indispensable laboratory test for many dynamic engineering and scientific research. [0003] At present, there is no membrane mounter that can be used in the triaxial test of soil dynamic strength. Engineers...
