Background
Anchor bolt support is a commonly used reinforcing support mode when carrying out side slope management, and the region of easily landslide usually adopts combination formula stock in order to strengthen the support intensity, and the mode of binding is usually adopted at present to be in the same place with stranded steel strand, and the steel strand twine twines together easily, influences the construction, inserts the back of anchor eye and slip casting with combination formula stock, can not fine laminating between stock and the slip casting, and the slip casting takes place tensile fracture easily after the atress, has weakened support intensity, influences the construction effect.
Disclosure of Invention
In view of the above, the present invention provides a detachable anchor positioning support with stable and reliable structure.
The anchor rod positioning and supporting piece comprises a base body which is formed by enclosing at least two arc-shaped supporting blocks and has a circular section, the arc-shaped supporting blocks are fixedly connected through elastic fasteners, a grouting pipe mounting hole is formed in the base body in a hollow mode, an anchor rod mounting hole is formed in each arc-shaped supporting block, and the axis of the anchor rod mounting hole is parallel to the axis of the grouting pipe mounting hole.
Furthermore, the outer arc surfaces of the arc-shaped supporting blocks are provided with grooves along the bending direction, the grooves are communicated with each other to form an annular groove for mounting an elastic fastener, and the elastic fastener is mounted in the annular groove.
Further, the elastic fastener is a spring or an elastic collar.
Furthermore, an included angle formed between a contact surface between two adjacent arc-shaped supporting blocks and a tangent line passing through the excircle of the base body is not equal to 90 degrees.
Further, a lubricant is arranged between the contact surfaces of two adjacent arc-shaped supporting blocks.
Further, the lubricant is polytetrafluoroethylene.
Further, the inner wall of one end of the anchor rod mounting hole is in smooth transition with the end face of the arc-shaped supporting block.
The invention has the beneficial effects that: the anchor rod positioning support piece is composed of a plurality of arc-shaped support blocks, the arc-shaped support blocks are fixedly connected through the elastic fasteners, the structure is stable and reliable, the anchor rods of the combined anchor rods respectively penetrate through anchor rod mounting holes, the anchor rods are supported and positioned through the anchor rod mounting holes, a plurality of anchor rods are arranged in order, grouting pipe mounting holes are used for fixing grouting pipes, the anchor rods are uniformly stressed after being inserted into the anchor holes and grouted, after the anchor rods are tensioned and prestressed, a plurality of support positioning blocks are separated in stress, grouting bodies are extruded, and the support strength is enhanced.
Drawings

Detailed Description
The invention is further described below with reference to the following figures and examples:
as shown in fig. 1 and 2, an anchor rod positioning support member comprises a base body, the cross section of which is formed by enclosing at least two arc-shaped supporting blocks 2 is in a ring shape, each arc-shaped supporting block 2 is fixedly connected through an elastic fastener 5, the structure is stable and reliable, a grouting pipe mounting hole 1 is formed in the base body in a hollow mode, the grouting pipe mounting hole 1 is used for positioning and supporting a grouting pipe, an anchor rod mounting hole 3 is formed in each arc-shaped supporting block 2, the axis of each anchor rod mounting hole 3 is parallel to the axis of each grouting pipe mounting hole 1, and each anchor rod mounting hole 3 is used for positioning and supporting an anchor rod.
In this embodiment, the outer arc surface of each arc-shaped supporting block 2 is provided with a groove 4 along the bending direction, each groove 4 is communicated with each other to form an annular groove for installing an elastic fastening piece 5, the elastic fastening piece 5 is installed in the annular groove, and the annular groove is used for positioning the elastic fastening piece 5, so that the elastic fastening piece 5 is prevented from moving along the outer arc surface of the arc-shaped supporting block 2, and the fastening effect is prevented from being influenced. The elastic fastening piece 5 generates radial pressure on the base body, so that the arc-shaped supporting blocks 2 are not easy to move relatively, and the elastic fastening piece 5 is a spring or an elastic clamping ring.
In this embodiment, an included angle formed between the contact surface 21 between two adjacent arc-shaped supporting blocks 2 and a tangent line passing through the excircle of the base body is not equal to 90 degrees, so that the arc-shaped supporting blocks 2 can slide more easily when the base body is stressed. And a lubricant is arranged between the contact surfaces 21 of two adjacent arc-shaped supporting blocks 2, and is preferably polytetrafluoroethylene, so that the arc-shaped supporting blocks 2 can slide mutually more easily.
In this embodiment, the inner wall of 3 one ends of stock mounting hole and the terminal surface rounding off of arc supporting shoe 2 when carrying out stretch-draw to the stock, increase stock and arc supporting shoe 2 area of contact, make arc supporting shoe 2 atress even to reduce the wearing and tearing of stock.
When the combined anchor rod is used, the anchor rods are respectively inserted into the anchor rod mounting holes 3, the grouting pipes are inserted into the grouting pipe mounting holes 1, then the combined anchor rod is inserted into the pre-drilled anchor holes for grouting, the combined anchor rod is tensioned by a tensioning machine after grouting is finished, prestress is applied, the base body is stressed, the plurality of arc-shaped supporting blocks 2 are separated, surrounding grouting bodies are extruded, and the arc-shaped supporting blocks 2 extrude the grouting bodies, so that the anchor rods are not easy to displace, the supporting strength of the anchor rods on surrounding rocks is enhanced, and the side slope supporting effect is improved.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
