Abstract

The utility model discloses an indoor triaxial test sample device, in particular to a device for demolding a remolded soil sample. Its composition includes: a soil sample forming cylinder, a demoulding ring, a base and a handle, and is characterized in that: the inner diameter of the upper part of the demoulding ring is the same as the inner diameter of the soil sample forming cylinder, and the inner diameter of the lower part is the same as the outer diameter of the soil sample forming cylinder Similarly, the demoulding ring can drive the soil sample forming ring to move downward, and the demoulding ring includes two fixed handles for applying vertical pressure. The utility model improves and innovates the traditional layered compacting device. It makes it very easy to demould after the sample is made, so that the sample can be guaranteed to be uniform and not damaged, and meet the requirements of saving time and effort.

Description

A device for demoulding of remolded soil samples

technical field

The utility model relates to an indoor remodeling soil test sample device, which belongs to the technical field of soil engineering experiments.

Background technique

In geotechnical tests, mechanical properties are very important for the design and use of geotechnical structures. The uniformity of remodeling soil, sample preparation, and control of various physical properties have greater advantages than undisturbed soil. The demoulding process of remolded soil has an important influence on the molding rate of soil samples. The traditional remolded soil sample preparation device is precise but not easy to demould. During the demoulding process, the uniformity of the soil sample will be destroyed, and even the soil sample will be unqualified. , resulting in a significant reduction in the accuracy of the test results. Therefore, need to design a kind of novel demoulding device of remodeling soil, avoid above-mentioned problem.

Utility model content

The purpose of the utility model is to solve the above technical problems and provide a demoulding device for remolded soil with simple operation, wide applicability, high sample forming rate and little disturbance.

In order to achieve the above object, the technical scheme of the utility model is as follows:

A device for demoulding remolded soil samples, comprising a soil sample forming cylinder, a demoulding ring and a base, characterized in that: there are two fixed handles on both sides of the demoulding ring, and the demoulding ring is round The inner diameter of the upper part of the demoulding ring is the same as the inner diameter of the soil sample forming cylinder, the inner diameter of the lower part of the demoulding ring is the same as the outer diameter of the soil sample forming cylinder, and the demoulding ring can be stuck on the top of the soil sample forming cylinder to drive the soil The sample forming cylinder moves downward, the base and the soil sample forming cylinder have the same inner diameter, and the base can move with the soil sample forming cylinder; handles are provided on both sides of the demoulding ring, and the experimenter can apply force through the handle Demoulding; the base is a solid cylinder with the same diameter as the inner diameter of the soil sample forming cylinder; the inner diameter of the base is the same as the lower part of the demoulding ring, and the height of the base is the same as that of the soil sample forming cylinder.

Compared with the existing technology, the advantages of the utility model are as follows: the soil sample is completely separated from the mold through the difference between the inner and outer diameters of the mold release ring and the soil sample.

A further technical solution is that the height of the soil sample forming cylinder is the same as that of the base, and the soil sample can be completely separated from the mold when demoulding.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

The utility model embodiment is:

Referring to accompanying drawing 1, the utility model provides a kind of device that is used for demoulding of remodeling soil sample, is made up of demoulding ring 1, soil sample forming cylinder 2 and base 3, described demoulding ring 1 and base 3, two are used together.

The utility model can be widely used in the demoulding of remolded soil samples, and here only the demoulding process of the utility model is taken as an example to illustrate its usage. First put the base 3 on the horizontal workbench, align the sample made by the layered compaction method with the base 3, then align the demoulding ring 1 on the soil sample forming cylinder 2, and adjust the demoulding ring 1 and the position of the base 3, the experimenter applies pressure vertically through the handles on both sides until the soil sample forming cylinder 2 breaks away from the reshaped soil sample.

The above-mentioned embodiment is only a preferred embodiment of the utility model, only to illustrate the technical concept and structural features of the utility model, and the purpose is to allow relevant technical personnel to implement it accordingly, but the above-mentioned content does not limit the utility model. The scope of protection of the new utility model, so all changes made according to the shape and principle of the utility model should be covered within the scope of protection of the utility model.
