Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] see figure 1 and figure 2 , the sealing structure of the multi-measuring-point sample of the true triaxial test is shown, including the sealing rubber sleeve 2 used to wrap the sample 1, and the sealing rubber sleeve 2 is arranged with four loading plates 7 in the front, rear, left, and right directions. Two plates 7 are connected by second bolts 11 , and the loading plate 7 and the bottom plate 8 encircle to form a loading cavity for placing the sealing rubber sleeve 2 . The bottom side of the base plate 8 is provided with a chute, and a slide block 9 is arranged in the chute, and the slide block 9 is fixedly connected with the loading plate 7 by using the first bolt 10, so that the loading plate 7 can slide along the base plate 8, and then the load plate 7 can slide according to the test needs. Adjust the position of the loading chamber for better true tr...

Abstract

The invention discloses a sealing structure of a multi-measuring-point sample of a true triaxial test, which includes a sealing rubber sleeve used to wrap the sample. The sealing rubber sleeve is provided with an injection well sealing assembly and a pressure probe seal at the end where the sealing seat is located. Assemblies, electrode contact sealing assemblies are arranged on the front, rear, left, and right sides of the sealing rubber sleeve. It can meet the sealing requirements of the test point of the sample and can be used repeatedly.

Description

technical field [0001] The invention relates to a true triaxial test system, in particular to a sealing structure for a multi-measuring point sample of a true triaxial test. Background technique [0002] Under simulated real formation conditions, when performing a triaxial compression test on a sample, it is necessary to lead out the measurement through the pressure point and the metal measuring point, which requires the sample to be sealed under high pressure and with multiple measuring points. The existing design scheme is to insert the probe, injection well or probe into the installation hole, and the gap between the probe, injection well or probe and the installation hole is sealed by resin glue casting. If this sealing method is adopted, the molding cycle of the installation process is long, and disassembly is difficult, and the probe, injection well or probe can only be used as a disposable item and cannot be reused. Therefore, it is necessary to develop a new type of...
