Heavy heterogeneous soil remodeling sample preparation device

Abstract

The invention provides a large soil preparation device for indoor heterogeneous soil sample preparation. A soil preparation unit is of a graded half-open cylinder structure, a water separation channel / washer and fixing lug buckles improve the leakproofness and quick detaching properties of a layered soil filling model, and the integrity of a soil body before and after a test is maintained; a base vibrator and a soil surface flattener improve convenience and accuracy in the manual making process of a large soil body model; a soil filling frame is of a spliced design, and multi-dimension joint can meet the requirement for internal filling of heterogeneous bodies of various sizes; for soil compaction, a manual rotation jack is adopted for compression, the compression thickness is controlled by the number of screw-in circles of a thread, and the purpose of controlling the density of the soil body is achieved.

Description

Technical field [0001] The invention relates to an indoor soil sampling device, in particular to an indoor production simulation device for heavy heterogeneous soil. Background technique [0002] At present, indoor soil tests generally use small-sized remolded soil and original samples as samples. In order to facilitate the expansion and calculation of various basic tests, the soil is usually made with reference to the size of the ring knife (such as a ring knife with a diameter of 61.8mm and a height of 20mm). , and mainly homogeneous soil or randomly filled heterogeneous soil, the relevant research results are very rich and relatively mature. The preparation of large-scale spatially quantitative heterogeneous soil samples has the limitations of high cost, small test expansion, and lack of analytical models, so relevant research results are very scarce. However, with the rapid development of urban construction, various Soil types emerge in endlessly. For example, the resea...

Problems solved by technology

The preparation of large-scale spatially quantitative heterogeneous soil samples has the limitations of high cost, small test expansion, and lack of analytical models, so relevant research results are very scarce. However, with the rapid development of urban construction, various Soil types emerge in endlessly. For example, the research on heterogeneous fill soil needs to be improved and developed urgently. The existing research results and analysis models of mean soil are difficult to apply to the design and construction of related soil engineering.
