Problems solved by technology

It can be seen from the operation process that the pressure chamber in the triaxial instrument needs to manually reciprocate the water tank to realize the water injection and drainage work of the pressure chamber. This method is relatively cumbersome, which makes it particularly inconvenient to use the triaxial instrument

Embodiment Construction

[0026] The present invention will be further elaborated below by means of the accompanying drawings and examples.

[0027] Such as Figure 1-9 Shown: a self-weight type triaxial instrument drainage device, including a container 1, a telescopic rod 2, a water tank 3, a pressure plate 4, a pressure plate 2 5, and a sealing member 6. The telescopic rod 2 is installed in the container 1 . The container 1 communicates with the water tank 3 through the water inlet pipe 13, and the bottom of the container 1 is provided with a water injection pipe 15, and the water injection pipe 15 communicates with the pressure chamber 16 in the triaxial instrument. The first pressing plate 4 is sleeved on the telescopic rod 2, and the second pressing plate 5 is movably sleeved on the telescopic rod 2, and is located above the first pressing plate 4.

[0028] The sealing member 6 is arranged between the first pressing plate 4 and the second pressing plate 5 . The outer edges of the first pressing...

Abstract

The invention discloses a dead weight type triaxial apparatus water injection and drainage device, comprising a container, a telescopic rod, a water tank, a pressing plate I, a pressing plate II and asealing component; the telescopic rod is mounted in the container; the container is communicated with the water tank by virtue of a water inlet pipe, a water injection pipe is arranged at the bottomof the container; the pressing plate I sheathes the telescopic rod; the pressing plate II movably sheathes the telescopic rod and is located above the pressing plate I; the sealing component is arranged between the pressing plate I and the pressing plate II; the diameters of the pressing plate I and the pressing plate II are smaller than the diameter of the container, and the end parts of the pressing plate I and the pressing plate II are wrapped and surrounded by an annular sealing ring; and the sealing component comprises a spring, a sheath ring, a connecting rod and a supporting rod. The dead weight type triaxial apparatus water injection and drainage device disclosed by the invention controls water injection and water drainage operations of a pressure chamber in a triaxial apparatus ina manual manner, water injection process can be controlled more conveniently, and structure design of a composition device is relatively ingenious, so that cost is lower, and the device disclosed bythe invention is more applicable to being put into production in commission.

Description

technical field [0001] The invention relates to the technical field of triaxial test devices, and relates to a self-weight triaxial test device for water injection and drainage. Background technique [0002] Before using the triaxial instrument, it is necessary to fill and drain the pressure chamber inside it for normal use. However, the existing operation process is as follows: when injecting water: move the water tank to the top of the triaxial instrument, and communicate with the water injection end of the pressure chamber through a hose, and press the water in the water tank into the pressure chamber by gravity to realize water injection; drain water Time: By moving the upper water tank to the lower part of the triaxial instrument and connecting it with the drain end of the pressure chamber, the water flows into the water tank from the pressure chamber through gravity to complete the drainage. It can be seen from the operation process that the pressure chamber in the tr...
