Making device for soil samples/rock samples with different moisture contents

Abstract

The invention relates to a making device for soil samples / rock samples with different moisture contents. The inside of the main case is a closed space, a bracket is disposed at the middle part in the main case, a weight detector is installed on the bracket, the weight detector is provided with a tray for weighing, the tray divides the space in the main case into an upper soil sample / rock sample placement space and a lower humidification space. The humidification space of the main case is internally equipped with a water tank, the water tank is internally provided with a heating unit, the main case is provided with a case door convenient put in and take out the soil sample / rock sample at the position where the soil sample / rock sample placement space is located, and the inside of the main case is equipped with an air pressure detector, a temperature detector and a humidity detector at the top of the soil sample / rock sample placement space. With the making device provided by the invention, the moisture states of the obtained soil samples / rock samples can be more uniform, the physical and mechanical properties of the soil samples / rock samples are stable and easy to control, also the operation process is simple, and the preparation efficiency is high.

Description

technical field [0001] The invention relates to a device for making soil samples / rock samples with different water contents. Background technique [0002] In geotechnical engineering, it is often necessary to use various soil / rock samples with different moisture contents for experiments. Since it is difficult to find natural soil / rock samples that meet the required moisture content, it is generally necessary to artificially prepare soil / rock samples with various moisture contents. Most of the existing methods for making soil samples / rock samples with different water contents are in the form of splashing and stirring. The main disadvantage is that although soil / rock samples with different moisture contents can be obtained by splashing and stirring, such soil / rock samples are generally not homogeneous, and may cause soil agglomeration due to uneven water distribution. Affect the physical and mechanical properties of soil / rock samples. The existing method of making rock samp...

The main disadvantage is that although soil / rock samples with different moisture contents can be obtained by splashing and stirring, such soil / rock samples are generally not homogeneous, and may cause soil agglomeration due to uneven water distribution. Affect the physical and mechanical properties of soil / rock samples

The existing method of making rock samples is mainly obtained by soaking in water and then baking, but the water distribution is difficult to achieve uniformity; in the public information, the rock samples are prepared in a constant temperature and humidity device, However, there are defects such as too long preparation time and poor matching
