Problems solved by technology
[0003] Because the existing technology is only a few consolidation coefficient tests under fixed pressure in the indoor test, it is impossible to obtain real-time data in a certain place in the field in real time. Moreover, during the indoor test, the result of sampling will cut off the plant root system, which affects the real time. The effect of the plant root system on the soil consolidation force, therefore, the experimental data has a large deviation

The invention discloses a device for measuring consolidation force of a tree root system to soil. The device for measuring the consolidation force of the tree root system to the soil is used for measuring the consolidation force of the tree root system to the soil in real time. The device for measuring the consolidation force of the tree root system to the soil comprises an outer cylinder, wherein a through hole is formed in the outer cylinder, a measuring head is arranged in the through hole, one end of the measuring head is a plane, the other end of the measuring head is a conical surface, a dowel bar is arranged inside the outer cylinder, a driving cone is arranged at the bottom of the dowel bar, the conical surface of the driving cone is matched with the conical surface of the measuring head, the upper portion of the dowel bar is connected with a threaded rod, the threaded rod is matched with a nut which is fixed to the upper portion of the outer cylinder, the threaded rod is fixedly connected with a force arm, and a force meter is arranged at the tail end of the force arm. The device for measuring the consolidation force of the tree root system to the soil has the advantages of being simple in structure, convenient to use, and applicable to measurement of land with any geographic features, and really reflecting the consolidation force of the plant root system to the soil of a location.
Description
technical field [0001] The invention relates to the field of instruments and meters, in particular to an environmental monitoring and monitoring device, more specifically to a soil consolidation force measuring device. Background technique [0002] As the concept of environmental protection is deeply rooted in the hearts of the people, countries are paying more and more attention to the environment. One of the important means to ensure a good environment is to use the consolidation effect of plants on the soil to prevent desertification of the soil and reduce the formation of harmful weather. Existing technologies often consider the soil condition through the soil consolidation coefficient, which reflects the index of soil consolidation speed. The consolidation coefficient depends on the permeability coefficient, void ratio and compressibility coefficient of the soil under a certain pressure, so the consolidation coefficient that is the same as the actual stress state (the ...
