Problems solved by technology

[0011] These test methods obviously have the following deficiencies: (1) Since the test principles for measuring the physical properties of soil are not the same, a corresponding measurement test needs to be designed for each physical property of the soil. Large amount and low work efficiency; (2) Most test data are recorded manually, with low degree of automation and insufficient precision

Embodiment Construction

[0041] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0042] Such as figure 1 Shown, the test method of measuring soil physical property index of the present invention, its main steps comprise: (1) gather soil sample---collect soil sample with the known soil sample collection container of volume; (2) weigh and Drying - put the soil sample collected in the first step on the weighing heating base and weigh it, and the weighing electronic measuring equipment will display the mass as m 1 , sent to the data storage and processing equipment through the data transmission line, and then the soil sample is heated and dried through the base, and the stabilized data is displayed by the weighing electronic measuring equipment, recorded as m 2 , sent to the data storage and processing equipment through the data transmission line, then m 2 is the mass of soil particles m s , m 1 with m 2 The difference...

Abstract

The invention relates to a method and a device for measuring physical property indexes of a soil body. The method comprises the following steps of: measuring six basic parameters, namely corresponding masses and volumes of soil particles, water and gas in the soil body; and calculating to acquire nine conventional physical property indexes of the soil body through running relevant programs by virtue of data storage and processing equipment, and displaying the nine conventional physical property indexes once, wherein the conventional physical property indexes of the soil body can be measured quickly and comprehensively.

Description

technical field [0001] The invention relates to a method for measuring soil physical property indexes and related measuring devices for implementing the measuring method, and belongs to the field of soil physical property index measurement methods and measuring instruments. Background technique [0002] Some physical properties of soil are mainly determined by the volume and mass (weight) ratio of the three phases of solid particles, water and gas in the pores that make up the soil. The indicators that reflect this relationship are called the physical properties of soil. index. The physical property index of soil can not only describe the physical property of soil and its state, but also reflect the mechanical property of soil to a certain extent. Therefore, in the implementation of many projects, it is very important to understand the physical properties of soil. [0003] Soil physical property indexes can be divided into two categories: one kind must be determined throug...
