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

In order to measure the soil consolidation force of forest tree roots in real time, the invention discloses a device for measuring the soil consolidation force of forest tree roots. One end of the head is a plane, the other end is a conical surface, a dowel rod is arranged inside the outer cylinder, and a driving cone is arranged at the lower part of the dowel rod, and the conical surface of the driving cone matches the conical surface of the measuring head; The upper part of the force rod is connected with the screw rod, the screw rod cooperates with the nut fixed on the upper part of the outer cylinder, the screw rod is fixedly connected with the force arm, and a dynamometer is arranged at the end of the force arm. The invention has the advantages of simple structure, convenient use, suitable for land measurement of any geographical features, and truly reflects the soil consolidation force of plant roots at the site.
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 ...
