Abstract

The invention provides a clay and sandy soil interbed soil sample preparation device and a use method thereof. The sample preparation device comprises a three-petal mold, a base, a hoop, a permeable stone, a freezing mold and a sampling handle. The freezing mold is used for preparing a frozen sand soil layer; the sampling handle is provided with a sucker for taking and placing the frozen sandy soil layer. The use method of the sample preparation device comprises the following steps: S10, preparing a clay soil paste and a frozen sand soil layer; S20, assembling a sample preparation device; S30,coating vaseline on the inner wall of the sample preparation barrel; S40, preparing interbed soil; and S50, carrying out compression molding. The interbed soil sample preparation device is simple instructure, the thickness of each layer in interbed soil is convenient to control, and the interbed soil sample preparation yield and sample preparation quality are high.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a clay-sand interlayer soil sampling device and a use method thereof. Background technique [0002] In my country's river, lake, and coastal areas, due to changes in the depositional environment and ocean dynamics, a soil layer in which clay and sand alternately appear is accumulated, commonly known as thousand-layer cake soil, or interbedded soil. The interbedded soil is often widely distributed, thick and special in nature. This kind of soil layer not only has the properties of general weak soil, but also has its own characteristics, and it is buried shallowly, and often becomes the bearing layer of the foundation of buildings and structures. Its physical and mechanical performance indicators directly affect the design and construction of foundations of buildings and structures. Construction and other engineering activities, so it is necessary to conduct labor...
