Embodiment Construction

[0053] The invention realizes the sample delivery in two directions through the specially designed two-way sample delivery component, realizes the sample delivery of the fissure network seepage test in one direction, and realizes the sample delivery of the single fixed fracture shear-seepage test in the other direction. The switch between the above two test functions is realized on the test equipment, which greatly facilitates the use of users. Based on this, a test system that can simulate the mechanical properties of rock samples under the joint action of stress field and water flow field is developed and manufactured, which can be applied to the experimental research on the failure mechanism of rock cracks under the joint action of stress field and water flow field.

[0054] It should be noted that in the following embodiments, the two-way sample delivery module is described as a two-dimensional rock sample fracture network seepage test device. Of course, in other embodimen...

Abstract

The invention provides a bidirectional sample conveying component and a two-dimensional rock sample seepage test device applying the bidirectional sample conveying component. The bidirectional sample conveying component comprises an underframe body, a sample conveying rotary table, a first sliding rail and a second sliding rail, wherein a test area is arranged above the middle position of the underframe body, and at least two sampling areas, namely a first sampling area and a second sampling area are arranged on a plane where the test area is positioned; the sample conveying rotary table is arranged above the test area and can rotate around a rotating shaft at the center of the test area, and a common sliding rail is arranged on the sample conveying rotary table; the first sliding rail is arranged between the first sampling area and the test area; the second sliding rail is arranged between the second sampling area and the test area; the common sliding rail can be spliced with the first sliding rail or the second sliding rail to form a complete sample conveying sliding rail. Through the specially-designed bidirectional sample conveying component provided by the invention, the sample conveying in the test area in two directions is realized.

Description

technical field [0001] The invention relates to the field of geotechnical engineering measuring instruments, in particular to a multi-directional sample delivery component and a two-dimensional rock sample seepage test device using the same. Background technique [0002] In recent years, with the construction of a large number of large-scale projects such as energy mining, nuclear waste treatment, water conservancy projects, and underground space utilization, rock seepage issues have attracted increasing attention. , fissure seepage has an important influence on the stability of rock mass engineering. On the one hand, cracks in rock mass are one of the important causes of water damage in underground engineering. On the other hand, the existence of cracks also greatly reduces the strength of rock mass. It is well known that fluid pressure in water-bearing pores can change the stress state in rock mass because water has little compressibility and easily transmits pressure. H...
