Problems solved by technology

[0009] In continuous production practice, the applicant found that the size of the soil sample cylinder of the prior art air pressure consolidation instrument is fixed, so the test can only be carried out on a soil sample of a certain size, but in reality, due to the difference in soil types and engineering backgrounds, It is often necessary to use soil samples of different sizes for testing, and the uniqueness of the size of the soil sample cylinder greatly limits the applicability of the air pressure consolidation instrument
In addition, there is no better solution in this field for the drainage problem of the air pressure consolidation instrument

Abstract

The invention provides an atmospheric pressure consolidation instrument for different soil sample sizes. The atmospheric pressure consolidation instrument is characterized in that a loading component and a soil sample cylinder component are separately arranged. A set of loading component is applicable to the soil samples in different sizes, so that the defect that the size of the traditional consolidation test soil sample cylinder is single and nonadjustable is overcome. The atmospheric pressure consolidation instrument is fit for the research on the soil consolidation characteristics of different soil properties under different engineering backgrounds and is higher in applicability. Meanwhile, through the combined application of water-permeable flagstone and hollow drainage rod, the consolidation atmospheric pressure applied to the soil sample and water injection / drainage in the soil sample are realized in a same pipeline system. The atmospheric pressure consolidation instrument is simple and practical. The defects of complexity and large volume of the traditional atmospheric pressure consolidation instrument are overcome.

Description

technical field [0001] The invention relates to the field of geotechnical engineering measuring instruments, in particular to an air pressure consolidation instrument adaptable to different soil sample sizes. Background technique [0002] With the rapid development of my country's economic construction and large-scale infrastructure construction nationwide, the issue of building settlement control has received increasing attention. Soil in nature is widely distributed, has complex properties, and varies in hardness and softness, resulting in a wide range of compression and settlement performances under the action of overlying building loads. Since the properties of soil vary from place to place and are highly unpredictable, if the engineering characteristics of the soil are ignored during the design and construction of the foundation, and special rectification of the soil is not carried out, it will have a major impact on the construction of the project. Based on this, it i...
