Embodiment Construction

[0024] The present invention will describe in detail the specific implementation of the present invention in conjunction with accompanying drawing:

[0025] see figure 1 , is the anchoring structure rheological testing machine of the present invention, the whole testing machine is installed on the loading frame, and the loading frame is composed of a base, a bracket and a bracket platform.

[0026] Among them, the sample clamp and the movable beam are installed on the support platform through the connection of the slot, and can move along the direction of the slot; the function of the sample clamp is to fix the sample and ensure that the sample will not be displaced laterally during the test. .

[0027] The function of the movable beam is to adjust the position and installation space of the anchor in the sample to ensure that the sample can meet the requirements of the test.

[0028] The hydraulic oil source can generate a test force of 10KN, but it cannot be maint...

Abstract

The invention provides a testing system and method for simulating rheological properties of an anchor rod and an anchoring body by utilizing an anchoring structure rheological testing machine. The anchoring structure rheological testing machine comprises a loading framework, a test sample clamping and movable transverse beam, a rheological loading device, a measurement and control device and a computer. The loading framework is provided with the anchor rod and the anchoring body and is fixed by a test sample clip; the anchor rod is loaded through the rheological loading device; a loading process is controlled by the computer, and various measurement parameters and a stress change curve of the anchor rod and the anchoring body are displayed in real time. The testing system is small in noises, has no pollution, is economical and is convenient to operate.

Description

technical field [0001] The invention belongs to the field of rheological systems, and specifically proposes a method for simulating the rheological characteristics of geological structures under the joint action of anchor rods and surrounding rocks by using an anchor structure rheological testing machine, which can effectively simulate the impact of different anchor lengths on the anchor rod itself. The distribution and change of the force structure, as well as the anchoring force radius and stress distribution under different anchoring conditions. [0002] Background technique [0003] In order to maintain the stability of the roadway and prevent the surrounding rock from collapsing or large deformation, bolt support is required. The "carrier" composed of the anchor rod and the supported surrounding rock has good rigidity and strength characteristics, so the anchor rod has the function of restraining the deformation of the surrounding rock and maintaining stability. There...
