Abstract
A steel pipe steel wire rope roadside bolt is suitable to support and reinforce the laneway whose wall rock is easy to be transversely staggered and the laneway of non-soft rock laneway. The utility model includes a steel pipe and a steel wire rope arranged in the steel pipe which is opened with 3-4 gaps; the top end of the steel pipe is provided with a tray and the tail end of the steel pipe is provided with a retaining ring with a cut; one end of the steel wire rope which is arranged in the steel pipe is fixed on the tray and the other end is fixed on a screw which is fixed on the retaining ring by a nut. When the wall rock is transversely staggered to make a bored hole buckle, the steel pipe steel wire rope roadside bolt is deformed incidentally and is more tightly contacted with the wall rock; the anchoring force is stronger; the rib spalling and the floor heave, etc. are effectively controlled. The installation is convenient, the anchoring is instant, and the supporting cost is low.
Description
Technical field
The utility model relates to a kind of steel pipe wire rope lane group anchor pole, is particularly useful for country rock and is 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.
Background technology
Anchor pole is widely used in the supporting of country rock, and the very big effect of performance, but is easy to the tunnel of the horizontal changing of the relative positions for country rock, can make the anchor pole that is adopted be cut off or produce loosening, causes anchor pole to lose support action, brings potential safety hazard to production.
The utility model content
The purpose of this utility model is the weak point that exists at prior art, provides a kind of simple in structure, is difficult for becoming flexible the steel pipe wire rope lane group anchor pole skill that supporting effect is good.
For achieving the above object, the steel pipe wire rope lane group anchor pole that the utility model adopts, it comprises steel pipe and is located at the interior wire rope of steel pipe, have 3～4 slits on the steel pipe, the top of steel pipe is provided with pallet, and tail end is provided with back-up ring with holes, wire rope one end that is located in the steel pipe is fixed on the collet, the other end is fixed on the screw rod, and screw rod is fixed on the back-up ring by nut, and wire rope and bolt length sum are equal to or slightly greater than steel pipe and nut length sum.When nut inwardly rotates, the protruding and tense wire rope of bolt along with continuing to increase of wire rope strength, makes the steel pipe dilatancy, with boring crag jam-packed, thereby produces anchored force.
3～4 slits offering on the described steel pipe are located at the leading portion of steel pipe, and wherein slit and steel pipe are isometric.Steel pipe is to adopt the high strength steel coiled sheet to be pressed into the pipe of band longitudinal joint, and caliber can be decided according to the boring size.
Adopt after the said structure, when the horizontal changing of the relative positions of country rock buckled boring, steel pipe wire rope of the present utility model lane group anchor pole was out of shape thereupon, contacted closelyr with country rock, and anchored force is stronger, can effectively control the wall caving, pucking in tunnel etc.This anchor-holding force of anchor bolt is strong, anchorage effect meets and is better than common bolt, simple installation, can instantaneous anchoring, solved country rock be easy to the horizontal changing of the relative positions the tunnel two help the control of surrouding rock deformation, and reduce material consumption and support cost, especially the country rock that is easy to the horizontal changing of the relative positions there is good adaptive capacity, in addition, can utilize the steel pipe of hollow and waste steel wire rope to make such anchor pole, greatly the economical with materials cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
Shown in Figure 1, it is made of wire rope 1, nut 3, pallet 4, steel pipe 5, back-up ring 6 and screw rod 7, wire rope 1 is located in the steel pipe 5, and pallet 4 is located at the top of steel pipe 5, and back-up ring 6 is located at the tail end of steel pipe 5, back-up ring 6 middle parts have a hole, wire rope 1 is located in the steel pipe 5, and the one end is fixed on the middle part of pallet 4 inboards, and the other end is fixed on the screw rod 7, screw rod 7 is fixed on the back-up ring 6 by nut 3, by adjusting nut 3 tense wire ropes 1.Have 2,3 slits 2,3 slits on the steel pipe 5 and open leading portion at steel pipe 5, wherein slit and steel pipe are isometric, shown in Figure 2.According to the diameter of steel pipe 5, the intensity size of steel, slit 2 can be offered 3, also can offer 4.Inside swivel nut 3, the protruding thereupon and tense wire rope 1 of bolt 7 along with continuing to increase of wire rope 1 strength, makes steel pipe 5 dilatancies, with boring crag jam-packed, thereby produces anchored force.Wire rope 1 and screw rod 7 length sums are equal to or slightly greater than steel pipe 5 and nut 3 length sums.
