Problems solved by technology

In the early days, the pressure-subsidence test was carried out with a portable Bayesian instrument, which was loaded with compressed air, but the power did not meet the requirements, while the portable cone index measuring instrument was powered by a battery and could penetrate to a greater depth, but its structure could not be installed with a pressure plate. Pressure-subsidence test, so it is difficult to ensure the comparability and feasibility of the test

Abstract

The invention provides a portable soil measuring test device capable of performing conical index measuring and a pressure-sinking test. The portable soil measuring test device comprises a support, a hydraulic mechanism, a measuring test mechanism and a controller; the support comprises a bottom plate, a guide column erected on the bottom plate and a fixing top plate connected with the upper end of the guide column; the hydraulic mechanism comprises a hydraulic cylinder, a hydraulic driving unit driving the hydraulic cylinder and a slide block; one end of the cylinder body of the hydraulic cylinder is connected with the fixing top plate and the other end of the cylinder body of the hydraulic cylinder is connected with the guide column by a fixing part; a free end of a piston of the hydraulic cylinder is connected with the sliding block; the guide column penetrates through the slide block to guide the same; the measuring test mechanism comprises a measuring rod, a measuring head and a built-in pull press sensor; one end of the measuring rod is connected with the slide block and the other end of the measuring rod is connected with the measuring head, the built-in pull press sensor is arranged internally between the measuring rod and the measuring head; the controller is fixed on the bottom plate of the support by a mounting frame and controls the hydraulic mechanism and the measuring test mechanism.

Description

technical field [0001] The invention relates to a portable soil measurement test device. Background technique [0002] In the technical field of soil mechanical parameter detection, soil cohesion modulus and soil friction modulus are two important soil characteristic parameters. These two parameters can be obtained through the pressure-subsidence test and the soil mechanics formula based on the semi-empirical theory. In addition, the cone index is a parameter representing the strength of the soil. Based on the experimental data, the correlation model between the soil cone index and these two parameters can be obtained, and these two parameters can also be calculated. [0003] It is very difficult to carry out the pressure-subsidence test on the ground with the most complex and common impact on the vehicle, because the portable equipment is insufficient in power and light in weight, and the vehicle installed with the vehicle-mounted equipment may change the state of the grou...
