Description

Technical Field

[0001] The utility model relates to the field of anchor rod support, in particular to an anchor rod support device. Background Art

[0002] Anchor support refers to a reinforcement support method used in surface engineering such as slopes, deep rock foundation pits, and underground chambers such as tunnels and stopes. Rods are made of metal, wood, polymer or other materials and driven into pre-drilled holes in the surface rock mass or the rock mass around the chamber. The special structure of the head and rod body and the tail support plate (optional) are used to combine the surrounding rock with the stable rock mass, or rely on bonding to produce a suspension effect, a composite beam effect, and a reinforcement effect to achieve the purpose of support. It has the advantages of low cost, good support effect, simple operation, flexible use, and less construction clearance.

[0003] Slope refers to a slope with a certain height and gradient. Construction slope refers to artificial slopes formed by excavation or filling construction in and around the construction site, and natural slopes that have an adverse effect on the safety or stability of the building. These slopes are generally subject to scouring, soil erosion, and shallow local landslides. Common measures for slope protection include mortar or cement plastering, civil grids, shotcrete, shotcrete, mortar-laid stone retaining walls, anchor spraying slope protection, anchor spraying net slope protection, etc.

[0004] At present, in slopes that have been artificially mined, due to the inclination of the slope surface, the soil, under the action of its own gravity, has a tendency to slide from high to low, posing safety hazards such as slope sliding. In addition, the existing slope reinforcement device is supported from the outside, and the support effect is limited. The entire slope rock and soil are unstable, which is prone to large-scale landslides, posing serious safety hazards. Utility Model Content

[0012] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0013] 1. The grid is laid on the slope body, and installed on the drilling machine through the mounting groove. After starting, the drill bit drills the slope body. After drilling to the appropriate position, the anchor rod body penetrates the grid and enters the slope body. The stop plug and the pad are inserted in sequence. The nut is rotated outside the thread so that the nut contacts the pad and presses the stop plug. The stop plug contacts the grid, thereby fixing the grid position.
