Device for preparing soil sample with specific water content as well as application thereof

Abstract

The invention provides a device for preparing a soil sample with specific water content as well as application thereof, and belongs to the technical field of geotechnical engineering. The device comprises a soil sample preparation device, a water storage device, a data acquisition and storage processor and a real-time control system, wherein the soil sample preparation device comprises a water spraying controller, a dry soil sprayer, a gravity sensor and a soil sample accommodating device. The device achieves the effect that the water content of the soil body is uniform and constant by combining layered spraying pavement of the soil layers and layered water spraying. As an example not limited and compared with the prior art, the device has the following beneficial effects that the uniformdegree of the water content of the soil body can be controlled well, in particular the problems that in the preparation process of the soil sample with the specific water content, the soil sample is agglomerated, the water content is non-uniform and the human factor has huge influence can be solved. The device is suitable for preparation of loess, sandy soil, expansive soil, in particular the sticky soil sample liable to agglomerate.

Description

technical field [0001] The invention belongs to the field of geotechnical engineering, and relates to a device for preparing soil samples with specific moisture content and application thereof. Background technique [0002] At present, many countries in the world, including my country, are carrying out engineering construction activities, and it is necessary to have sufficient understanding of foundation soil before engineering construction. Indoor test is one of the main methods to understand the properties of soil. Many indoor tests need to prepare soil samples with specific moisture content before carrying out the test. How to quickly and efficiently prepare high-quality soil samples with specific moisture content is the first problem to be solved before other indoor tests. [0003] At present, the manual mixing method is mainly used to prepare soil samples with specific moisture content. The manual mixing method is to put a certain quality of dry soil in the container,...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a device for preparing soil samples with a specific moisture content and its application, which is suitable for the preparation of soil samples with a specific moisture content, and is especially suitable for the preparation of cohesive soil samples. The device can effectively solve the problems of agglomeration and agglomeration of soil samples prepared by manual mixing method, uneven moisture content of soil samples, inaccurate moisture content of soil samples, adverse health effects, and relatively large influence of human factors.
