Embodiment Construction

[0065] This embodiment is a parallel intelligent pressurized triaxial sample preparation process. The working process of this application is as follows:

[0066] (1) Preparation before experiment

[0067] According to the stress history, deposition conditions and particle composition of the soil used in the experiment, determine the pressure to be applied during the experiment and the time required for the experiment.

[0068] (2) Instrument preparation

[0069] ① First determine whether the amount of filler in the upper power part 11 of the pressure mechanism 1 is sufficient, and its gravity should make the upper pressure spring 46 press to the exact design height, check whether there is filler in the lower power part 12, if there is no filler, use The upper cross bar 31 is in a horizontal state.

[0070] ②Fix the special latex film inside the cylinder 52. When placing it, try to keep the length of the latex film on both sides longer than the length of the cylinder 52 consi...

Abstract

The application relates to a parallel intelligent pressurized triaxial sample preparation technique and belongs to the technical field of indoor geo-techniques of civil engineering. The parallel intelligent pressurized triaxial sample preparation technique includes: (1) preparing before an experiment, to be specific, determining magnitude of pressure to be applied in the experiment process and experiment-required time according to stress history, depositional conditions and particle composition of experimental soil; (2) preparing instruments; (3) placing a soil sample; (4) compacting; (5) extracting the soil sample; (6) resetting the instruments, and preparing a next sample according the steps of (1) to (5). The parallel intelligent pressurized triaxial sample preparation technique enablestriaxial sample preparation pressure and time to be intelligently controlled, enables multiple samples to be formed at a time, ensures shorter sampling time and less disturbance upon a soil sample, overcomes the defect that traditional sample tube sampling is difficult and has certain engineering applicability.

Description

technical field [0001] The application relates to a parallel intelligent pressurized triaxial sample preparation process, which belongs to the field of indoor geotechnical technology of the civil engineering discipline. Background technique [0002] With the increase of construction projects on soft soil foundations in coastal areas, the test of soft soil mechanical properties has become an important content in current civil engineering. Triaxial test is a common experimental method to measure the mechanical properties of soft soil. The sample is cylindrical with a diameter of 3.91cm and a height of 8.0cm. During the experiment, 3-5 standard samples need to be made to test 3-5 different The mechanical properties of soft soil under confining pressure. Usually, manual compaction is used to uniformly compact the soil sample to achieve the target soil sample compactness, and manual demoulding is used. Due to the low efficiency of making samples one by one, it is difficult to a...
