Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of indoor geotechnical experiment, and relates to a geotechnological experiment device, in particular to a novel geotechnological experiment film-accepting cylinder. BACKGROUND

[0002] In indoor geotechnical experiment, super-large triaxial test is a very important test project, and many large and medium-sized water conservancy and hydropower projects need to carry out super-large triaxial test to provide relevant parameters for stability and deformation calculation. The film-accepting cylinder is an essential accessory for preparing test pieces in super-large triaxial test.

[0003] For the preparation of test samples in super-large triaxial test, the traditional film-accepting cylinder adopts a detachable whole component, which consists of a cylinder plate, an air hole at the middle part of the cylinder, a screw for connecting the cylinder plate, a handle for carrying the cylinder plate, a rubber ring and a rubber paste.

[0004] Before the present application, in the process of preparing super-large test samples in indoor experiment, the bottom end of the rubber film is first turned over to cover the base and is tightly fastened with a rubber ring and is installed on the base, the cylinder plate is carried to the base by the handle, the screw is connected to form a hollow cylinder, the cylinder is installed on the base to cover the rubber film, the top end of the rubber film is turned over to cover the top of the cylinder and is tightly fastened with a rubber ring, the connection between the cylinder plates is sealed with a rubber paste, the air pump sucks air through the air hole on the cylinder to make the rubber film tightly adhere to the inner wall of the cylinder, the rubber film forms a hollow cavity, the soil material is filled into the rubber film, and finally when the soil material is filled, all the screws and rubber paste are removed to complete the preparation of the test sample. As can be seen, in the traditional test sample preparation process, the film-accepting cylinder needs a large number of screws for connection and rubber paste for sealing, and the rubber film is tightly fastened with the base and the cylinder, so the device has the above defects: 1. A large number of screw connections make the installation and disassembly process of the film-accepting cylinder extremely cumbersome and inconvenient to operate; 2. The screw connection and the rubber paste sealing method cause poor air tightness of the film-accepting cylinder; 3. The disassembly process easily disturbs the test sample, thereby affecting the accuracy of the related experiment of the soil test sample. SUMMARY
