Section 2 body of rod is reliably connected, and waits strong ties device two ends all to have a pin-and-hole, and makes the 2nd, Section 3 body of rod and connector by pin
Being fixed into an entirety, by that analogy, compound rod length is up to more than 10 meters；Upon recovery, the combined segment body of rod is reversely rotated, the
The 1 knot body of rod and the first connector separate, and the combined segment body of rod integrally detaches country rock；Merogenesis takes alignment pin apart again, by combined segment bar
Body is divided into multiple sub bar body, it is simple to transport preserves；
The anchoring section end of the first connector and the anchoring section body of rod are welded, it is simple to the combined segment body of rod is when reversion, with the
A connector separates；
Second connector uses alignment pin further, it is to avoid in removal process, depart between sub bar and sub bar, and
Make the parton body of rod cannot reclaim in being retained in country rock；
Owing to the body of rod of anchor pole can a section be attached by waiting strong ties device, the bar length of anchor pole is made to reach
More than 10m, and quick recovery portion in addition to anchoring section for the anchor pole can be reversely rotated by the hexagonal prismatic termination of body of rod end
Point, to reuse, economical and practical；
Sphere combination nut, it is simple to pallet centering, improves anchoring effect；
This bolt product is easy, low cost, installs and reclaims conveniently, and practical, the rate of recovery is high, has good popularization
It is worth and higher economic benefit.
By the surrounding rock consolidation in tunnel together, country rock self supporting self is made.Utilize the shearing resistance of anchor pole surrounding formation ground
Intensity carrys out the pulling force of transferring structure thing to keep the homeostasis of stratum excavation face, and due to the use of anchor pole, it can provide work
For on works to bear the drag of outer lotus；Anchoring stratum can be made to produce compression district and play reinforcement work to strengthening stratum
With；The intensity on stratum can be strengthened, improve the mechanical property on stratum；Structure can be made to be chained together with stratum, form one
Cooperative entirety so that it is can effectively bear pulling force and shearing；
The anchor pole being connected by connector, is adapted to the demand of different supporting height, can replace anchor cable, and can facilitate
Recovery, remarkable in economical benefits.
Brief description
Fig. 1 is the structural representation of a kind of combined anchor of the utility model.
Detailed description of the invention
By making, architectural feature of the present utility model and the effect reached are had a better understanding and awareness, in order to relatively
Good embodiment and accompanying drawing coordinate detailed description, are described as follows:
As it is shown in figure 1, a kind of combination rod-type anchor pole, anchor pole includes the anchoring section body of rod 2 and the combined segment body of rod；The anchoring section body of rod
2 are connected by the first connector 3 with the combined segment body of rod；The combined segment body of rod and the first connector 3 removably connect；Combined segment bar
Body has more piece sub bar body 1；More piece sub bar body 1 is connected by the second connector 4 successively head and the tail；Second connector 4 and sub bar body 1
Between fix also by alignment pin 8.
Detach from country rock smoothly for the ease of the combined segment body of rod, the first connector 3 that the utility model provides and combination
Being detachably connected as between the section body of rod is threaded, and the first connector 3 is threaded connection with the anchoring section body of rod 2 and uses week
Corner weldering positioning.When inverting hexagonal prismatic termination, i.e. unclamp threaded, make the combined segment body of rod integrally depart from the anchoring section body of rod
2.Certainly, use alignment pin 8 to fix between sub bar body 1 and sub bar body 1, it is to avoid in Umklapp process, a certain sub bar body 1 with
Sub bar body 1 departs from and is retained in country rock and cannot reclaim.
For the ease of reversely rotating the combined segment body of rod, the combined segment body of rod that the present invention provides is away from the one of the anchoring section body of rod 2
End is hexagonal prismatic termination 5, it is also possible to be other terminations being easy to rotate.
Anchor pole also includes pallet 6, it is simple to realize lifting reinforcing to country rock；Pallet 6 is fixed on by sphere combination nut 7
Have on the sub bar body 1 of hexagonal prismatic termination 5.
The alignment pin 8 that the utility model provides is pin；The two ends of sub bar body 1 radially begin with pin-and-hole；Second connector 4
The position corresponding with pin-and-hole offers the pin-and-hole coaxial with pin-and-hole；Pin sequentially passes through the pin-and-hole of the second connector 4, sub bar body
The pin-and-hole of 1, makes the second connector 4 and sub bar body 1 be fixed as one.
The first connector 3 and the second connector 4 that the utility model provides such as are at the strong ties device.
The utility model provide combination rod-type anchor pole, have reinforcing arch action, suspension function, combination beam effect,
Country rock strengthening action, reduction span function, particularly as follows:
(1) suspension function is in stratified rock, and anchor pole is suspended in the rock stratum that bottom is unstable on firm rock stratum, top.
Pulling force suffered by anchor pole is from the rock stratum weight being suspended.
(2) combination beam acts in the lamelliform rock stratum not having firm ground, by the pre-tensile stress of anchor pole, will be regarded as group
Close each slice jam-packed of beam, improve its self-bearing ability.The principal element of decision combination beam stability is the pre-tensile stress of anchor pole
And lever strength and nature of ground.
(3) reinforce arch action and for the bulk cut by crisscross plane of weakness or rupture shape country rock, if used in time
Bolt anchorage, just can improve the shearing strength of rock mass structure plane of weakness, forms one not in the range of country rock periphery certain thickness
It is only capable of maintaining homeostasis, and the reinforcing arch of its top wall rock loosening and deformation can be prevented, thus keep stablizing of tunnel.
(4) reduce span effect back and stamp anchor pole, be equivalent to stamp some post in this place.Therefore, it is equivalent to
Span back rock being hanged dew reduces, thus improves the bending resistance of roof strata.
Of the present utility model general principle, principal character and of the present utility model advantage have more than been shown and described.One's own profession
Skilled person will appreciate that of industry, the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply principle of the present utility model, on the premise of without departing from the utility model spirit and scope, the utility model also has respectively
Plant changes and improvements, in the range of these changes and improvements both fall within claimed the utility model.The utility model requires
Protection domain defined by appending claims and equivalent thereof.
