Collection device of earth-stone binary medium earth-pillar and hydrologic parameter measurement system and method

Abstract

The invention discloses a collection device of an earth-stone binary medium earth-pillar and a hydrologic parameter measurement system and method, and belongs to the technical field of the earth-pillar test. A pre-collected earth-pillar is placed in a specific device so as to be detected. The integrity and the stability of the original earth-pillar structure, physical character, and the chemical character can be well guaranteed, thereby effectively overcoming the obstacle that the traditional external force-embedded earth-sampling way cannot smoothly and accurately collect the original earth-pillar due to more gravels; the size setting is flexible, the operation is convenient and labor-saving, the joint mixture can be injected through injection holes around a sampler so as to fill the cracks, and the collection requirement of the large-size original earth-pillar can be satisfied; the advanced embedding of more sensors can be satisfied by means of the injection holes, the damage causedby the secondary development of the earth-pillar is reduced, and the accuracy of the earth-pillar test monitoring is improved. The obtained original earth-pillar containing the gravels is closer to the original state, thereby providing more scientific and accurate test sample for subsequently researching the subsequent earth-stone binary medium.

Description

technical field [0001] The invention relates to a device and a method for collecting a soil column in an earth-rock binary medium and measuring its hydrological parameters, and belongs to the technical field of soil column testing. Background technique [0002] The undisturbed soil column refers to the undisturbed soil column whose natural structure has not been damaged by external forces, and the soil column does not undergo deformation such as torsion or compaction during the sampling process. Undisturbed soil column collection is one of the important sampling methods in geology, soil science, agronomy, forestry and other disciplines. [0003] The Taihang Mountains are one of the important water sources in the North China Plain, and the soil-rock binary mixed medium is widely distributed on the hillsides. Crushed stones have greatly changed the basic physical properties and structure of the soil, resulting in soil moisture characteristic parameters and infiltration, flow ...

Problems solved by technology

[0005] In view of the defects or deficiencies of the above-mentioned existing methods, the technical problem to be solved by the system and method for the collection of soil-rock binary medium soil column and the measurement of its hydrological parameters disclosed by the present invention is: to realize the collection of soil-rock binary medium soil column It has the following advantages: (1) The disturbance to the undisturbed soil column is small, which can well ensure the integrity and stability of the undisturbed soil column structure, physical properties, and chemical properties, and effectively overcome the traditional external force embedding (2) The size setting is flexible, the operation is convenient and labor-saving, and the caulking agent is injected through the injection hole around the sampler to fill the gap, which can Meet the collection requirements of large-scale original soil columns; (3) With the help of injection holes, more sensors can be buried in advance, reducing the damage caused by the secondary development of soil columns, and improving the accuracy of soil column test monitoring
