A device and method for measuring the disturbance range of soil after sampling

Abstract

The invention belongs to the technical field of soil property measurement, and particularly relates to a device and method for measuring disturbance range of a soil body after sampling. The problem that in the prior art, disturbance can influence a measurement result and errors occur is solved. According to the technical scheme, the device comprises a gridding probe system and a linear driving mechanism, wherein the gridding probe system comprises a grid plate; the grid plate is connected with the linear driving mechanism; the linear driving mechanism is vertically arranged; the grid plate comprises a first grid plate and a second grid plate; the first grid plate and the second grid plate are connected with the same number of single probe systems used for detecting penetration resistance respectively; and a test sample box and a control sample box are arranged under the first grid plate and the second grid plate respectively. By comparing probe penetration resistance data of a test group and a control group, the disturbance range can be conveniently and visually determined, and the device and method are suitable for measuring the disturbance range of the soil body after sampling.

Description

technical field [0001] The invention belongs to the technical field of soil property measurement, and in particular relates to a device and method for measuring the disturbance range of soil after sampling. Background technique [0002] There are several physical and mechanical characteristics of the soil itself, such as density, porosity, shear strength, etc., and these characteristics are usually kept unchanged by default. However, it has been proved through experiments that after the relevant equipment shovels, digs, and penetrates the soil, the original structure of the soil is destroyed, and the soil will be disturbed within a certain distance from the operating range, and the disturbance will cause soil damage. changes in mechanical properties. [0003] In the prior art, most measuring devices focus on measuring a single physical quantity, such as displacement, penetration resistance, etc., and do not propose the concept of disturbance and disturbance range. On the p...

Problems solved by technology

[0003] In the existing technology, most of the measuring equipment focuses on measuring a single physical quantity, such as displacement, penetration resistance, etc., and does not propose the concept of disturbance and disturbance range

Under the premise of not considering the disturbance, when the corresponding measurement is carried out on the measured soil, the existence of the disturbance will have a certain impact on the measurement, which will directly cause the error of the measurement result
