Devices for determination of reinforcing property ROOT SYSTEMS COVERING SOILS IN THE STUDY cutting areas

摘要

The invention relates to devices used for the study of soils and can be used in devices to determine the reinforcing property of the root systems of soil cover in the study of the cutting area during its preparation for the logging operations, planning routes skid trails. The device for determining reinforcing ability root soil coating systems for cutting areas study involving a vertical rod having a handle at one end thereof and a tip - to another, - a tip formed as a fixed perpendicular to the rod areas, on the working surface which nests mounted uniformly spaced spring loaded needle under the heels are installed normally open contacts connected in the power feeding from a single electrical circuit, comprising a digital device for counting the number of closed contacts, with the handle mounted around a wire connected with the working surface of the tip indicator scale which is graduated in percentage of closed contacts. The utility model will improve the efficiency of the device by improving its design, ensuring efficiency and accuracy of the test index and expansion of the range of indicators due to the simultaneous study of large surfaces, the size of which includes the size of the track intended to perform logging operations mover skidders and side lanes trails . The result of determination of the reinforcing ability of root systems under soil cover study cutting areas device claimed is the aspect ratio square root of the surface layer to the total soil-ground area deformable in contrast to the prior art. 2 p.
