[0002] Anchor support is a commonly used reinforcement and support method for slope treatment. In areas prone to landslides, combined anchors are usually used to enhance the support strength. Nowadays, multi-strand steel strands are usually combined in a bundled manner. At the same time, the steel hinge wires are easy to be entangled together, which affects the construction. After inserting the combined anchor rod into the anchor hole and grouting, the anchor rod and the grouting body cannot fit well, and the grouting body is prone to pull when it is stressed. Tensile fracture weakens the support strength and affects the construction effect

Embodiment Construction
[0014] The present invention will be further described below in conjunction with accompanying drawing and embodiment:
[0015] Such as figure 1 and figure 2 As shown, a anchor rod positioning support includes a base body with a circular cross-section surrounded by at least two arc-shaped support blocks 2. Each arc-shaped support block 2 is fixedly connected by elastic fasteners 5. The structure Stable and reliable, the interior of the matrix is hollow to form a grouting pipe installation hole 1, the grouting pipe installation hole 1 is used to position and support the grouting pipe, the arc-shaped support block 2 is provided with an anchor rod installation hole 3, and the anchor The axis of the rod installation hole 3 is parallel to the axis of the grouting pipe installation hole 1, and the anchor rod installation hole 3 is used for positioning and supporting the anchor rod.
[0016] In this embodiment, the outer arc surface of each arc-shaped support block 2 is provided ...

The invention discloses an anchor rod positioning support part which comprises a circular-ring-shaped base body enclosed by at least two arc-shaped supporting blocks and provided with a circular-arc-shaped cross section. The arc-shaped supporting blocks are fixedly connected through elastic fastening parts, the base body is internally hollow to form a grouting pipe installing hole, the arc-shapedsupporting blocks are provided with anchor rod installing holes, and the axes of the anchor rod installing holes are parallel to the axis of the grouting pipe installing hole. The anchor rod positioning support part is stable and reliable in structure, combined anchor rods penetrate through the anchor rod installing holes, the anchor rods are supported and positioned through the anchor rod installing holes so that the anchor rods can be orderly arranged, the grouting pipe installing hole is used for fixing a grouting pipe, the multiple anchor rods are uniform in stress after the anchor rods are inserted into the anchor holes and grouting is performed, the anchor rods are stretched and drawn to exert a prestressing force, stresses of multiple supporting and positioning blocks are separated,a grouting body is extruded, and the supporting strength is improved.
Description
technical field [0001] The invention relates to the field of slope support, in particular to an anchor rod positioning support. Background technique [0002] Anchor support is a commonly used reinforcement and support method for slope treatment. In areas prone to landslides, combined anchors are usually used to enhance the support strength. Nowadays, multi-strand steel strands are usually combined in a bundled manner. At the same time, the steel hinge wires are easy to be entangled together, which affects the construction. After inserting the combined anchor rod into the anchor hole and grouting, the anchor rod and the grouting body cannot fit well, and the grouting body is prone to pull when it is stressed. Tensile fracture weakens the support strength and affects the construction effect. Contents of the invention [0003] In view of this, the object of the present invention is to provide a structurally stable, reliable and detachable anchor rod positioning support. [...
