The rock mass disintegration tester solves the shortcomings of existing rock or soil disintegration instruments such as complex structure and incomplete functions, and has a simple structure, complete functions and convenient use.

Description

A rock and soil disintegration tester

technical field

The utility model relates to a rock and soil disintegration test instrument, in particular to an engineering experiment instrument for measuring the disintegration of rock or soil.

Background technique

In geotechnical engineering science, disintegration is an important technical characteristic, and the research on disintegration of rock and soil is very necessary. At present, there are few types of instruments used to measure the disintegration of rock and soil, and most of them have complex structures, incomplete functions, and high costs.

Contents of the invention

In order to solve the shortcomings of the existing rock and soil disintegration instrument, such as complex structure and incomplete functions, the utility model provides a rock and soil disintegration test instrument, which has simple structure, complete functions and convenient use.

The technical solution adopted to achieve the above-mentioned purpose of the utility model is: a rock and soil disintegration tester, at least including a hollow tube and a screen, the bottom of the hollow tube is closed, scales are marked on the tube wall, and the screen is suspended outside the hollow tube. at the bottom of the hollow tube.

The hollow tube is composed of several sections of detachable tubes, and the sections are connected by screw ports. The bottom of the hollow tube is in the shape of an inverted cone, and the bottom of the hollow tube is provided with an iron ring weight.

The rock-soil disintegration tester is placed in a transparent container filled with solution, the disintegration sample is placed on the screen, and the number of iron ring weights and the height of the hollow tube are adjusted according to the floating situation, so that Floats vertically in solution. Record the initial readings. With the disintegration of rock and soil on the screen, its mass decreases, and the hollow tube floats up. Record the readings of the hollow tube at regular intervals, so as to obtain the disintegration speed of rock and soil in different periods, and draw the relationship between time and rate. Variation curve; observe the rock and soil disintegration phenomenon in different periods at the same time. Because the number of iron ring weights and the height of the hollow tube can be adjusted, the rock and soil disintegration tester is suitable for disintegration experiments of rock and soil samples of different specifications, and the rock and soil disintegration tester is simple in structure and low in cost .

Among them, 1-hollow tube, 2-detachable tube, 3-iron weight, 4-screen.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figure 1, the rock and soil disintegration tester provided by the utility model mainly includes a hollow tube 1, an iron ring weight 2 and a screen 4, and the screen 4 is located outside the hollow tube 1 and is suspended from the bottom of the hollow tube 1. . The hollow pipe 1 is composed of several sections of detachable pipes 2, and the sections are connected by screw ports, as shown in FIG. 2 . The tube wall of hollow tube 1 is marked with scale, and its bottom end is closed. The bottom of the hollow tube 1 is in an inverted conical shape, and a detachable hoop-type weight 3 is arranged on it. The inner wall of the hoop-type weight 3 is provided with threads, and is connected with the bottom of the hollow tube 1 through threads.

Place the disintegration sample to be measured on the screen 4, place the rock and soil disintegration tester in a transparent container filled with liquid, and adjust the iron level according to the specification weight of the rock or soil and the overall floating condition of the disintegration tester. The number of ring weights 3 and the height of the hollow tube 1 allow the disintegration tester to float vertically in the container and record the initial reading. As the rock or soil disintegrates, its mass gradually decreases, the hollow tube 1 floats up, and the readings of the hollow tube 1 are recorded at regular intervals, and the reduction of the rock or soil can be calculated according to Archimedes' law Quality, get the disintegration speed of rock and soil in different periods, and draw the change curve of time and rate; at the same time, you can observe the disintegration phenomenon of rock and soil in different periods.

The rock and soil disintegration tester can not only measure the disintegration of rocks, but also can be used to measure the disintegration of soil, suitable for disintegration experiments of samples of different specifications and qualities, and the rock and soil disintegration tester The structure is simple and the cost is low.
