Experimental device and method for strengthening soft foundation under vacuum

Abstract

The invention relates to the technical field of soft foundation treatment, in particular to an experimental device and method for strengthening soft foundations under vacuum. The experimental device includes a box body, a vacuum drainage system and a test system. Two partitions are arranged in the box body, and the two partition boards separate the box body into two water chambers and an accommodating chamber for containing the experimental soil. , the two water holding chambers are respectively located on opposite sides of the housing chamber, wherein a plurality of water seepage holes are provided on the partition, and the water holding chamber communicates with the housing chamber through the water seepage holes for Accurately and effectively simulate the hydrogeological conditions in actual engineering, the vacuum drainage system drains the water in the experimental soil and consolidates the experimental soil, the test system collects various data in the experiment for research, provides scientific data for theoretical research, and promotes In-depth study of the soft foundation consolidation treatment method under the action of vacuum.

Description

technical field [0001] The invention relates to the technical field of soft foundation treatment, in particular to an experimental device and method for strengthening soft foundations under vacuum. Background technique [0002] There are soft soil foundations widely distributed along the river, along the river, along the lake and in the coastal areas of our country. With the rapid growth of the national economy and the expansion of cities, industrial and civil construction projects and traffic engineering will inevitably have more and more problems with these soft soil foundations. The closer the intersection. In order to ensure the quality of engineering construction and operational safety, soft foundation reinforcement is indispensable, and the vacuum preloading method is an effective soft foundation treatment method, which has achieved great success in domestic and foreign applications. The mechanism of soil consolidation is still controversial, which seriously restricts...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a soft foundation reinforcement experimental device under the action of vacuum that can accurately simulate the hydrogeological conditions in actual engineering, and has a simple structure, so as to obtain various accurate parameters of the experimental soil in the experiment, so as to solve the problem of the existing vacuum action. The experimental device for the consolidation mechanism of soft foundations is not enough to support the theoretical research of the consolidation mechanism of soft foundations under vacuum
