Description

Undisturbed sample loader

Technical Field

The application relates to a non-disturbance sample loader, which belongs to the technical field of soil mechanics experimental equipment.

Background

In soil mechanics, experimental tests on mechanical properties of soil samples are often required. During testing, the soil sample needs to be made into a specified shape, such as a cylinder, a cuboid and the like, and then placed in an experimental device for testing the mechanical property, and during the experiment, the disturbance to the soil sample needs to be reduced as much as possible.

A common high-precision resonant column experimental instrument is a GCTS resonant column experimental system. As shown in figures 1-3, when the experiment is carried out, firstly, the rubber film 2 is sleeved inside the sample loader 1 as shown in the figure, and the upper end 21 and the lower end 22 of the rubber film 2 are respectively sleeved on the outer wall of the sample loader 1 in an everting way. The rubber film 2 is tightly pasted on the inner wall of the sample loader 1 by vacuumizing the air exhaust pipe 3 on the sample loader 1, then the sample loader pasted with the rubber film is sleeved on the soil sample, the contact between the soil sample and the outside air or water is isolated, and the original shape and the stress state of the soil sample are kept.

When the soil sample is loaded, as shown in fig. 2, the soil sample and the sample loader are placed together on the lower base 32. Then the sampler needs to be taken out, as shown in fig. 3, the rubber film 22 at the lower end is sleeved on the lower base 32, the upper end rubber film is turned upwards to turn out the sampler, the upper base 31 is lifted, and the sampler is taken out after being lifted to the bottom end of the motor on the upper base. Because the limit distance's between upper portion base and the lower part base restriction among the experimental apparatus, when the high great of dress appearance ware, the dress appearance ware that need be crooked when taking out, soil sample 23 also can be inclined this moment, especially in the base position, soil sample and base be virtual contact, and soil sample 23 often can be bent off with the fingers and thumb. In addition, disposable filter paper is required to be placed between the soil sample 23 and the upper and lower bases for water penetration and prevention of soil particles scattering. At this time, the filter papers placed on the upper and lower bases are also dislocated and difficult to fix, and the soil sample needs to be corrected by hands after the sample loader is taken out, so that the soil sample is vertically erected between the upper and lower bases. However, in the experiment, the soil sample is required to be fixed after being placed between the upper base and the lower base in principle, otherwise, the original compact soil body is disturbed, and the accuracy of the experiment result is affected.

In practice, to ensure that the original soil is not disturbed, the upper base and all the related upper parts, such as the motor, the sensor and the like, are usually disassembled. The method for disassembling the upper structure is time-consuming, and along with the increase of the disassembling times, the aging and the damage of the circuit are easily accelerated, the sensitivity of the sensor is reduced, and the operation is very inconvenient. In addition, in the operation process, two persons are required to operate simultaneously to successfully install the device. Wherein, one person is responsible for the lifting motor and keeps a take the altitude, and the dress appearance ware of built-in soil sample is taken out to another person's both hands.

Therefore, the above experimental device in the prior art has the following technical defects: the disturbance to the soil sample is inevitably increased in the experimental process, and the accuracy of the experimental result is influenced; the operation process can be carried out only by matching two persons, so that the experiment efficiency is low; the soil sample is shaken in the installation process, so that the soil sample and the filter paper between the upper base and the lower base are staggered.
