Abstract

The invention relates to an instrument for measuring soil adherence force, which is structurally characterized in that the top part of a steel frame is connected with a hydraulic dynamometric system; the lower end of the hydraulic dynamometric system is connected with a different material replaceable testing head through a telescopic rod; a pressure regulating system and the hydraulic dynamometric system are connected through a copper pipeline in the steel frame; a detachable sample box is fixed above a housing of the pressure regulating system; an oil pressure valve and a handwheel are arranged on one side of the housing; and the pressure regulating system is fixed on a base plate. The different material replaceable testing head is driven by the hydraulic dynamometric system through the telescopic rod to transmit pull force and pressure in different directions, so as to measure the adherence force between different materials and soil of different types and states. The instrument for measuring soil adherence force provides test data and technical guidance in reducing energy consumption and improving engineering building quality for civil and military transportation.

Description

technical field [0001] The invention relates to an instrument for measuring soil cohesion. Background technique [0002] The cohesiveness (cohesiveness) of soil is the interaction between the solid constituents of the soil and external objects through bound water film and transition type water. Combined water film and transitional water, on the one hand, interact with soil particles, and on the other hand, contact with external objects, so a stress is generated, and the force between them is compound, and this effect is relatively close to the cohesive force (adhesion), this force is called cohesion. Due to the existence of this force, large vehicles or means of transport will consume excess power when operating on bare land in the wild, thereby affecting their work efficiency and consuming excess power resources. Especially in the military field, when large-scale combat and transport machinery travel on the ground, the adhesion between the wheels and the ground affects th...
