Experimental device with easy-to-disassemble adjustable anchorage length and experimental method thereof

Abstract

The invention relates to an experimental device with easy-to-disassemble adjustable anchorage length, which comprises a support, wherein a plurality of layers of front quadrangular enclosing plates are vertically arranged on the front side of the upper side of the support through two front screw components; a plurality of layers of rear quadrangular enclosing plates are vertically arranged on therear side of the upper surface of the support through two rear screw components; a layer of left flat enclosing plate is arranged on the left side of each layer of the front quadrangular enclosing plate and the rear quadrangular enclosing plate; a layer of right flat enclosing plate is arranged on the right side of each layer of the front quadrangular enclosing plate and the rear quadrangular enclosing plate; an anchorage experimental panel is horizontally arranged on the front screw component and the rear screw component; a plurality of vertical pass-through anchorage holes are formed in theanchorage experimental panel. The invention further discloses an experimental method of the experimental device with easy-to-disassemble adjustable anchorage length. The experimental device with easy-to-disassemble adjustable anchorage length and experimental method thereof in the invention can simulate the whole process of the roadway bolt or anchor cable support in an intuitive system, facilitate the research of the on-site anchor bolt or anchor cable support construction process, and also facilitate the detection of the quality of the on-site anchor bolt or anchor cable support; meanwhile,the anchoring process of the roadway bolt or anchor cable can be simulated.

Description

technical field [0001] The invention belongs to the technical field of coal mine roadway support, and in particular relates to an experimental device and an experimental method for an easily disassembled and adjustable anchorage length. Background technique [0002] At present, anchor rod or anchor cable support has become a safe and efficient main support method for coal mine roadways, and has been widely promoted and applied in coal mine roadways in my country. Bolt or anchor cable support is to anchor the anchor rod or anchor cable in the coal rock body, tighten the anchor rod or anchor cable end nut (lock), apply pre-tightening force to the surrounding rock, and restrain the deformation and separation of the roadway surrounding rock. Swelling and slippage. Studying the axial load and axial deformation performance of bolt or cable support is of great significance for deepening the research of bolt or cable support mechanism, improving the reliability of bolt or cable sup...
