Fully automatic rock wet and dry cycle and permeability instrument

Abstract

The present invention relates to a fully automatic rock wet and dry cycle and permeability instrument which is characterized by comprising a drying chamber, a permeation chamber, an expansion chamber, a rotating carrying platform rack and a rock sample carrying platform and other components. By automatic rotation of the rotating carrying platform rack, a rock sample is sent to different laboratories, then through automatic sealing technology of the rotating carrying platform rack and the laboratories, the rock sample is extracted, and the laboratories are automatically sealed for testing. By use of the fully automatic rock wet and dry cycle and permeability instrument, the same rock sample can be placed in three laboratories for repeatedly testing in turn to obtain a variety of physical data of the rock sample under wet and dry cycle and permeability tests, and a reference for study on internal structural changes of rock under wet and dry cycle and permeability conditions is provided.

Description

Technical field: [0001] The invention belongs to the field of development of rock physics testing machines, and in particular relates to a fully automatic rock dry-wet cycle and infiltration instrument, which is suitable for automatic detection and collection of test data in dry-wet cycle and infiltration tests of rock samples. technical background: [0002] Red bed soft rocks generally exist in southern China, and the south is the area where rainfall is concentrated in my country, and the weather and climate environment change frequently. Therefore, in the construction of major projects in this area, after the soft rock is excavated, the dry The cycle of alternating wet and wet causes the internal structure of the rock mass to be loose, and the strength is rapidly reduced, resulting in frequent occurrence of engineering disasters such as slopes, tunnels, and foundation pits. Therefore, the study of the catastrophe mechanism of soft rocks under the action of dry-wet cycles ha...

AI Technical Summary

Problems solved by technology

However, the existing dry-wet cycle and permeability test instruments have relatively single functions on the one hand, and can only carry out repeated dry-wet cycle experiments on rock samples through independent drying or water immersion, which has low efficiency and high cost; on the other hand, the degree of automation Low, the measurement data is completed manually, resulting in large human errors
