Abstract

The invention provides an automatic operation platform for rapidly analyzing the porosity of soil at different depths, which comprises a workbench, a soil sampling device, a soil cutting device and awater injection device, wherein the soil sampling device, the soil cutting device and the water injection device are respectively arranged on the workbench; the soil sampling device comprises an external sleeve, wherein the axis of the external sleeve is perpendicular to the surface of the workbench and is in sliding connection with the workbench, a rectangular fixing frame is mounted at the bottom of the external sleeve, four longitudinal cutters are mounted at the edge of the lower surface of the fixing frame, the lower ends of the four longitudinal cutters are edged, and an internal soil sampling box with an opening at the lower end is fixedly mounted at the inner wall of the four longitudinal cutters. According to the automatic operation platform for rapidly analyzing the porosity of soil at different depths, soil sampling, soil cutting and water injection are integrated, so that the porosity of soil at different depths can be rapidly analyzed, the field scientific investigation operation is convenient and simple, and the experiment is carried out at the first time, so that other environmental interferences are reduced to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of soil porosity detection, in particular to an automatic operation platform for quickly analyzing soil porosity at different depths. Background technique [0002] The freeze-thaw cycle is the process of continuous freezing and thawing of the soil, which redistributes the water in the soil and weakens the structure, and changes the original skeleton and fabric of the soil, which are closely related to the porosity of the soil. Relationship. It is determined by experiments that with the increase of freeze-thaw times, the porosity of the original loess fluctuates between 0.325-0.426, while the porosity of the remodeled loess fluctuates between 0.348-0.433. plastic loess. [0003] Especially in the Qinghai-Tibet Plateau region, the freeze-thaw cycle has great significance for the change law of soil porosity. Under the continuous freeze-thaw cycle, the soil porosity changes repeatedly and unevenly. Most of th...
