Embodiment Construction

[0049] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0050] Such as figure 1 As shown, a large-scale and complex surrounding rock condition anchoring and grouting integrated coupling test system includes an underground simulation system 3; wherein the underground simulation system 3 includes: a sealed box 31, and several uniformly arranged on the inner wall of the box 31 The lateral pressure unit 2 that independently provides lateral extrusion force, wherein the lateral pressure unit 2 is uniformly arranged on the inner wall, facilitates pressure on the coal rock mass 1 in the sealed box 31 through the side wall, and the box 31 is filled with coal Rock mass 1; wherein, the lateral pressure unit 2 includes: several extrusion plates that are controlled by hydraulic cylinders and perform telescopic movement relative to the inner space of the box body 31 . Specifically, the specific struct...

Abstract

The invention discloses a large-scale complex surrounding rock condition bolting-grouting integrated coupling effect test system and method, and the system mainly comprises a sealed box body, a plurality of side pressure units which independently provide side extrusion force are sequentially and uniformly arranged on the inner wall of the box body, and the box body is filled with a coal and rock mass or an analog simulation material; a plurality of transverse shearing units, and a twisting unit for twisting the grouting anchor rod and a stretching unit for controlling the twisting unit to stretch linearly are sequentially arranged in the linear direction of the embedded anchor rod or the grouting anchor rod of the test system. The free end of the grouting anchor rod embedded in the test system is detachably connected with the grouting device. Through the large-scale underground simulation test system, the mechanical properties of a common anchor rod and a grouting anchor rod under thesingle-factor or multi-factor coupling action of pulling, twisting, shearing, cutting and bending under complex geological conditions can be simulated; and deformation rules and mechanical propertiesof the underground rock mass and the grouting rock mass under complex conditions can be simulated, and seepage diffusion rules of different slurries and changes of rock mass strength are tested.

Description

technical field [0001] The invention relates to the field of mine support equipment and detection and test equipment thereof, in particular to a test system and method for an anchor-grouting integration coupling effect under large-scale complex surrounding rock conditions. Background technique [0002] Bolt support has become an efficient support method for coal mine roadways, tunnels and slopes, and has been widely promoted in my country. Taking coal mines as an example, bolts can not only increase the anchoring force of the anchored coal and rock mass, but also improve the mechanical properties of the coal and rock mass through grouting, preventing the displacement of the two sides of the roadway and the bottom of the roadway floor. [0003] After the bolt is driven into the surrounding rock of the roadway, the actual stress situation under the action of the surrounding rock is very complicated. A bolt is subjected to one or more combinations of forces under the conditions...
