Description
Technical Field
The utility model relates to a stock mechanics effect presentation device, especially the presentation device that can demonstrate the anchor mechanics mechanism of stock belongs to teaching auxiliary assembly technical field.
Background
The anchor rod is a rod-shaped structure which is anchored in the rock body to maintain the stability of the surrounding rock. The anchor rod is used as the main component of the support system for the fixed rock of the underground engineering, and the anchor rod support system is formed. The anchor rods reinforce the surrounding rocks of the roadway together, so that the surrounding rocks support the surrounding rocks. The conventional anchor rod is not only used for mines, but also used in engineering technology for reinforcing main bodies such as side slopes, tunnels, dam bodies and the like. The anchor rod is used as one of main support forms of underground engineering and rock slopes, plays an important role in maintaining the stability of civil engineering, and particularly has an obvious reinforcing effect on rock bodies in joint fissure rock bodies.
At present, the theoretical research of anchor bolt support at home and abroad mainly adopts three theories of traditional suspension, composite beam and composite arch, and the theory of action of anchor bolt support is explained by different angles and different conditions.
At present, no matter any one of the theories is adopted for research at home and abroad, the research on the supporting effect and principle of the anchor rod is less, and devices for demonstrating the three theories are rare. In the past teaching, due to the fact that rock stratum is not visible in actual geotechnical engineering, the action mechanism of the anchor rod cannot be visually displayed, a demonstration experiment of the stress characteristic of the anchor rod is lacked in the teaching process, teachers can only explain complex stress according to partial graphs on textbooks, students lack visual perceptual knowledge, particularly the visual knowledge of the anchor rod anchoring mechanical action mechanism is difficult, and therefore the students are influenced to deeply, comprehensively learn and correctly apply the stress characteristic of the anchor rod.

the utility model discloses the technical scheme who adopts does:
the utility model discloses a theory of operation is:
the device can demonstrate the anchor rod anchoring action mechanism of the arch under the action of the following two different principles:
a, extrusion reinforcement: after the anchor rod is stressed, a compression area is formed in a certain range around the anchor rod. The bolts are arranged in a suitable manner so that the compression zones formed by adjacent bolts overlap each other to form a compression band. The loose stratum in the compression band is reinforced through the anchor rod, and the wholeness reinforcing, bearing capacity improve.
b, combining the beam functions: after the anchor rod is inserted into the stratum to a certain depth, the stratum is mutually extruded under the action of anchoring force, the interlayer friction is increased, the internal stress and the deflection are greatly reduced, and the method is equivalent to changing a plurality of simply superposed beams into a composite beam. The bending rigidity and the strength of the composite beam are greatly improved, so that the bearing capacity of the stratum is enhanced. The greater the anchoring force provided by the anchor rod, the more obvious the effect.
c, suspension action: the anchor rod penetrates through soft, loose and unstable rock-soil bodies and is anchored on the deep and stable rock-soil bodies to provide enough tension, so that the dead weight and the gliding force of the gliding rock-soil bodies are overcome, and the slippage and the collapse of the tunnel wall are prevented.
The utility model provides an anchor rod mechanics effect presentation device, includes the base and sets up the frame demonstration case on the base, and the frame demonstration case comprises a plurality of frame, and the top and the bottom of frame demonstration case are open structure, and the lower part outside of frame demonstration case is provided with the frame that encloses that is used for installing the die block board, and the die block board passes through the die block double-screw bolt and is connected with a frame foundation. The bottom template is provided with evenly arranged orifices, one end of the anchor rod is provided with a tray and a nut, and the end is arranged above the bottom template.
Since the technical scheme is used, the beneficial effects of the utility model are that the beneficial effect who gains is:
the device is simple in assembly, good in visualization effect, simple in structure and convenient to operate, can well demonstrate the suspension effect, the extrusion reinforcement effect and the combined arching effect of the anchor rod, and can quickly understand the anchor rod supporting mechanism particularly for the anchor rod which is in first contact. The defects that the anchoring effect process of the conventional anchor rod simulation test is not obvious, the test model is difficult to prepare and the like are overcome.
