Problems solved by technology

[0003] At present, in the process of simulating a test that approximates the permeable surrounding rock, it is necessary to use a water-permeable sleeve device, such as a kind of indoor test water-permeable sleeve disclosed by the notification number CN215339431U, but the metal water-permeable sleeve set The connection strength between the mesh cylinder and the sand cylinder is not high. When the bentonite expands, it may cause deformation and damage at both ends of the sand cylinder. In addition, during the test, it needs to be fixed by bolts, which is cumbersome and time-consuming, which reduces the test efficiency.

Abstract

The invention discloses a water-permeable sleeve device for indoor tests, and belongs to the technical field of geotechnical engineering test devices.The water-permeable sleeve device is characterized in that a mounting groove is formed in one end of a metal net cylinder, the inner wall of the mounting groove is in contact connection with a sand cylinder, one end of the metal net cylinder is sleeved with a reinforcing sleeve, and the other end of the metal net cylinder is in contact connection with a bottom plate; the surface of the bottom plate is in contact connection with a test water tank, one side of the test water tank is fixedly connected with a connecting sleeve, and the inner wall of the connecting sleeve is rotatably connected with a rotating rod. Meanwhile, one end of the sand cylinder and one end of the metal net cylinder are reinforced through the reinforcing sleeve, the supporting strength of the water-permeable sleeve is greatly improved, the sleeve can be conveniently and rapidly fixed in the test water tank to be tested through the arranged extrusion plate with the adjustable position, and the test efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering testing devices, and more particularly, to a water-permeable sleeve device for indoor testing. Background technique [0002] Studying the influence of groundwater infiltration through the surrounding rock of the repository on the internal system of the repository is an important topic in the research on the geological disposal of high-level radioactive waste. [0003] At present, in the process of simulating the surrounding rock with similar permeability, it is necessary to use a water-permeable sleeve device, such as an indoor test water-permeable sleeve disclosed in Bulletin No. CN215339431U, but the water-permeable sleeve is provided with metal The connection strength between the mesh cylinder and the sand cylinder is not high. When the bentonite expands, the two ends of the sand cylinder may be deformed and damaged, and during the test, it needs to be fixed by means of bolts, ...
