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 dynamic triaxial test soil sample film loader which comprises a triangular fixing device and a film loading device, the triangular fixing device can be divided into a triangular base fixing device and a triangular top frame fixing device through disassembly, and the film loading device can be divided into a soil sample vertical pier, a soil sample sleeve, a soil sample sleeve lifting rod and a rubber film pressing ring through disassembly. One set of film loading device is prepared for each of common soil samples with the diameter of 39.10 mm and the diameter of 50.00 mm; and according to the invention, the problem that the appearance and dynamic strength of soil are easily damaged when a soil sample is loaded by a film loading device in the prior art is solved, the success rate of soil sample film loading is increased, the speed of soil sample film loading is increased, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the field of dynamic strength triaxial tests of soil, in particular to a soil sample film loading device for soil dynamic triaxial tests. Background technique [0002] The dynamic strength triaxial test of soil refers to prepare the undisturbed soil or remolded soil as a soil sample of a certain specification, put the rubber film in the real triaxial or false triaxial testing machine, and set the required three-way dynamic strength Load value (or confining pressure value, vertical dynamic load value), dynamic load frequency, etc., apply dynamic load to the 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 indoor test for many dynamic engineering and scientific research. [0003] At present, there is no film installer that can be used in the membr...
