Abstract
A plastic steel wire rope anchor rod comprises a wire rope, a pallet and a lockset; a plastic steel pipe and a wedged iron slice wedged with the plastic steel pipe are arranged on the wire rope; and a steel bushing is arranged in the inside diameter of the plastic steel pipe, and a plurality of expansion joints are formed on the outside diameter thereof. Compared with the prior art, the plastic steel wire rope anchor rod has the advantages of simple and convenient installation and capability of instant anchoring, is applicable to the support of the two sides and the base angle of a roadway, in particular to the support and the reinforcement of the two sides of the roadway of which the country rock is dislocated easily in the cross direction and the roadway which is not soft rack, and can efficiently control the sides and the heaving floor of the roadway; and the anchor rod has excellent adaptive capacity to the country rock which is dislocated easily in the cross direction. When a drilling becomes bent, the plastic steel wire rope side anchor rod is in closer contact with the country rock, and the anchorage force is stronger. Besides, the plastic steel wire rope anchor rod can be made of hollow plastic steel pipes and recyclable wire ropes, so that the cost is greatly reduced.
Description
Technical field
The utility model relates to a kind of anchor pole, and the plastic-steel rope bolt with the base angle supporting is helped in especially a kind of tunnel two that is applicable to.
Background technology
The extensively utilization in mine support of steel anchor pole, but for supporting and reinforcing that the country rock that is easy to the horizontal changing of the relative positions and non-soft rock class tunnel two are helped, also there is not specially suitable special anchor pole class support material at present.
Summary of the invention
Technical problem: the purpose of this utility model provides a kind of two controls of helping surrouding rock deformation that country rock is easy to the tunnel of the horizontal changing of the relative positions that solve, and reduces the plastic-steel rope bolt of material consumption and support cost.
Technical scheme: plastic-steel rope bolt of the present utility model, comprise wire rope, pallet and lockset, described wire rope is provided with the plastic-steel steel pipe, and is provided with and the plastic-steel steel pipe wedge shape iron plate of wedging mutually.
The internal diameter of described plastic-steel steel pipe is provided with steel bushing, has many shrinkage joint on the external diameter; Described many shrinkage joint are three, become 120 ° of arrangements.
Beneficial effect: plastic-steel rope bolt of the present utility model, utilize the active rigid wall reinforcement mechanism of bolt support, and extruding reinforcing arching action principle, compared with the prior art, simple installation can instantaneous anchoring.Help supporting with the base angle applicable to tunnel two, be particularly useful for country rock and be easy to the tunnel of the horizontal changing of the relative positions and supporting and the reinforcing that non-soft rock class tunnel two is helped, can effectively control wall caving, the pucking in tunnel.The country rock that is easy to the horizontal changing of the relative positions is had good adaptive capacity, and when boring buckled, plastic-steel wire rope lane group anchor pole contacted tightr with country rock, and anchored force can be stronger.In addition, can utilize the recycling wire rope of hollow plastic-steel steel pipe and recovery to manufacture, save cost greatly.
Description of drawings
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model structure side view.
Among the figure: 1-wire rope, 2-wedge shape iron plate, 3-plastic-steel steel pipe, 4-pallet, 5-lockset, 3-1 steel bushing, 3-2 shrinkage joint.
The specific embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
Shown in Figure 1, the plastic-steel rope bolt is by wire rope 1, and the wedge shape iron plate 2, plastic-steel steel pipe 3, pallet 4 and the lockset 5 that are located on the wire rope 1 constitute.Wherein: wedge shape iron plate 2 and plastic-steel steel pipe 3 are located at wire rope 1 termination portion, and pallet 4 and lockset 5 are located at the anchor pole afterbody; The internal diameter of plastic-steel steel pipe 3 is provided with steel bushing 3-1, has three shrinkage joint 3-2 on the external diameter.Article three, shrinkage joint 3-2 becomes 120 ° of arrangements, and is shown in Figure 2.Wedge shape iron plate 2 is a plurality of and plastic-steel steel pipe 3 wedging mutually.The head of wire rope 1 is fixed by wedge shape iron plate 2 and plastic-steel steel pipe 3 wedge shapes, makes the wire rope tensioning by the anchorage cable stretching device between afterbody lockset 5 and the pallet 4, thereby produces anchored force.Wedge shape iron plate 2 can have screw thread to increase rubbing action with the wire rope contact surface.Stressed when anchor pole, along with the tensioning of wire rope 1, wedge shape iron plate 2 can tightly pin wire rope, thereby plays interconnect function.
During installation, at first will penetrate plastic-steel steel pipe 3 by one of the wire rope that lockset 5 connects, at the bottom of with a steel pipe plastic-steel steel pipe 3 of wire rope termination and wire rope being sent into the hole together gently, tray 4 and wire rope lockset 5 subsequently, and with the anchorage cable stretching facility with the wire rope tensioning, along with continuing to increase of wire rope strength, wedge shape iron plate 2 pushes closely more with the plastic-steel steel pipe.Then successively with pallet 4, nut, lockset 5, pulling force is fastening gets final product by design with anchor pole to use anchor pole (anchor cable) stretcher at last.
