A device for making soil/rock samples with different moisture content

Abstract

A device for making soil samples / rock samples with different moisture content. The main box is a closed space. A bracket is installed in the middle of the main box. A weight detection device is installed on the bracket. The weight detection device is equipped with a weighing tray. The space inside the main box is divided into the space for placing soil samples / rock samples on the upper side and the humidification space on the lower side. There is a water tank in the humidification space of the main box, and a heating device is installed in the water tank. The main box is placed in the soil / rock sample The position of the space is provided with a box door for putting in and taking out the soil sample / rock sample, and an air pressure detection device, a temperature detection device and a humidity detection device are arranged on the top of the soil sample / rock sample storage space in the main box. The invention makes the water content state of the obtained soil sample / rock sample more uniform, the physical and mechanical properties of the soil sample / rock sample are stable and easy to control, the operation process is simple and convenient, 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
