AI Technical Summary

Technical Problem

Existing methods for preparing aerated soil samples cannot monitor drainage in real time, resulting in inconsistent soil moisture content and making it difficult to ensure the consistency of the initial state of parallel samples. Furthermore, the sample preparation equipment lacks dimensional compatibility and ease of operation.

Method used

Gravity sensors are used to monitor the drainage volume in real time during the consolidation process. Zeolite powder adsorbs gas to form slurry. The final mass is calculated by back-calculating the target moisture content. A flip-up sample stage is used to adapt to different size requirements, simplifying the hardware structure.

Benefits of technology

It enables quantitative control of aerated soil samples, ensures consistency of moisture content among multiple samples, improves the versatility and ease of operation of sample preparation equipment, and reduces equipment cost and maintenance complexity.

Abstract

The present application relates to geotechnical engineering soil test technical field, disclose a kind of quantitatively preparing different water content gas-containing soil sample preparation method and device, and the sample preparation method is: dry soil powder, gas-free water and the zeolite powder mixed uniformly with adsorbed gas are prepared gas-containing mud;The mud is poured into the acrylic sample consolidation tube on gravity sensor to obtain initial total mass;Then the mud is subjected to gravity consolidation by pressure device;According to the mass of each component and the target water content, the target final mass is calculated;The total mass is reduced to the target final mass and remains unchanged when the gravity sensor is used to monitor in real time during consolidation and drainage, and the consolidation is stopped;The device includes a base, a vertical rod, a reversible sample table with a fixed buckle, a consolidation tube, and a pressure device. The present application uses zeolite powder as an internal gas phase physical carrier, combined with gravity sensor dynamic monitoring and cutting off the drainage path, to accurately prepare the soil sample with water content and gas content.
