Description

Technical Field

[0001] This utility model relates to the field of anchoring technology, and in particular to an anchor for deep hole anchoring. Background Technology

[0002] Cable anchoring is a key technology for reinforcing underground rock structures. Through the anchoring effect of the cables, it promotes a collaborative load-bearing mechanism between the support structure and the surrounding rock, providing reliable technical assurance for safe construction in underground engineering. Traditional cable anchoring systems, such as end-anchored or full-anchored structures, have potential failure risks. The core problem lies in the fact that when the roof strata and the surrounding rock of the slope migrate or are located in fractured zones such as fault zones, the interface between the anchoring agent and the rock mass is highly susceptible to debonding damage due to changes in stress conditions. Once this interface debonding occurs, it signifies a sharp decrease or loss of the load-bearing capacity of the anchoring structure, leading to a chain reaction that can cause local or even regional instability and collapse of the entire support system. Such systemic support failure can cause significant safety and economic losses.

[0003] In the construction of cable anchoring for tunnel roof support, the traditional procedure requires binding the anchoring agent to the front end of the anchor cable and then manually or mechanically pushing it into the predetermined anchoring section deep within the borehole. However, rock cuttings, fissures, or localized borehole collapses can cause damage to the anchoring agent packaging during long-distance pushing, leading to resin leakage and reduced bond strength. Simultaneously, the accumulation of broken anchoring agent residue or the anchoring agent's insufficient rigidity causing wrinkling and jamming in curved sections of the borehole can block the pushing path. Especially in areas with fractured or delamination roofs, the anchoring agent is prone to falling into the delamination voids, preventing it from reaching the designed depth, weakening the anchoring force, and increasing the risk of support failure.

After the anchor push head passes over the third wedge block and the fourth wedge block along the wedge-shaped inclined surface of the third wedge block and the fourth wedge block, the third wedge block and the fourth wedge block prevent the anchor push head from retracting.

[0010] According to one possible implementation of this utility model, the push connection device has a detachable structure.

[0011] According to one possible embodiment of the present utility model, the hinged base is connected to the first limiting steel plate and the second limiting steel plate respectively via hinge shafts.

[0012] According to one possible embodiment of the present utility model, the first limiting steel plate and the second limiting steel plate are symmetrically arranged on the side of the hinged base facing the anchor push head.

Detailed Implementation

[0018] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0019] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] See Figure 1 and Figure 3 As shown, an embodiment of the present invention provides an anchor for deep hole anchoring, comprising: an anchor body 1, an anchoring agent pushing device 2 provided at a first end of the anchor body 1, and an anchor fastening device 3 provided at a second end of the anchor body 1; The anchoring agent pushing device 2 includes: a pushing connection device 10, the first end of which is connected to the anchor body 1 and the second end of which is connected to the anchor push head 8; a hinged base 4, on which a first limiting steel plate 5 and a second limiting steel plate 6 are hinged, the first limiting steel plate 5, the second limiting steel plate 6 and the hinged base 4 forming a V-shaped receiving cavity 7; the anchor push head 8 is disposed in the receiving cavity 7 and is connected to the second end of the pushing connection device 10; At the relative positions on opposite sides of the first limiting steel plate 5 and the second limiting steel plate 6, there are corresponding blocking structures and anti-detachment structures for the anchor push head.

[0021] This anchor can be used for anchoring in deep holes (such as 10m-15m) in underground engineering rock masses.

[0022] The anchorage for deep hole anchoring provided by this utility model has an anchoring agent pushing device 2 at the first end of the anchorage body 1. The anchoring agent pushing device 2 includes: a pushing connection device 10, the first end of which is connected to the anchorage body 1 and the second end of which is connected to the anchorage push head 8; and a hinged base 4, on which a first limiting steel plate 5 and a second limiting steel plate 6 are hinged. The first limiting steel plate 5, the second limiting steel plate 6 and the hinged base form a V-shaped receiving cavity 7. During the pushing process, the V-shaped structure can protect the anchoring agent so that the anchoring agent can be reliably pushed into the predetermined anchoring section at the depth of the borehole, avoiding damage to the packaging of the anchoring agent during the pushing process, which would lead to leakage of the anchoring agent.

[0023] An anchor pusher 8 is provided within the V-shaped structure, and the anchor pusher 8 is fixedly connected to the first end of the anchor body 1. At opposite positions on opposite sides of the first limiting steel plate 5 and the second limiting steel plate 6, an anchor pusher 8 blocking structure and an anti-detachment structure 9 are provided. With the aid of the anchor pusher blocking structure, the anchor pusher 8 can push the anchoring agent pushing device 2 forward to the predetermined anchoring section. After the anchor pusher 8 pushes the anchoring agent pushing device 2 forward to the predetermined anchoring section, the anchor pusher 8 continues to push forward, and the first limiting... The steel plate 5 and the second limiting steel plate 6 open, and the anchor pusher 8 squeezes the anchoring agent 11, causing the packaging of the anchoring agent 11 to break. The anchoring agent 11 overflows and anchors the first end of the anchoring agent pushing device 2, the anchor pusher 8, and the anchor body 1 to the predetermined anchoring section. The anti-detachment structure 9 is set at the corresponding position on the opposite side of the first limiting steel plate 5 and the second limiting steel plate 6 to prevent the anchor pusher 8 and the anchor body 1 connected to it from falling off, further enhancing the reliability of the anchor body 1 in the predetermined anchoring section.

[0024] In some embodiments, the hinge base 4 is a cylindrical base with two circular surfaces that are concave from the circumference to the center. The hinge base 4 has a first through hole (not shown in the figure). During the forward movement of the anchor push head 8, the anchoring agent 11 is squeezed. After the anchoring agent 11 is squeezed and the packaging breaks, it overflows along the first through hole on the hinge base 4, so that the hinge base 4 is fully anchored to the rock wall at the bottom of the deep hole under the action of the anchoring agent, thereby improving the stability of the deep hole anchoring.

[0025] Furthermore, the circular surface of the hinged base 4 away from the anchor push head 8 is provided with grooves in different directions (not shown in the figure). The first through hole is provided at the intersection of the grooves. During the forward movement of the anchor push head 8, the anchoring agent 11 is squeezed. After the anchoring agent 11 is squeezed and the packaging is broken, the anchoring agent overflows from the first through hole. After overflowing from the first through hole, the anchoring agent flows along the direction of the groove and fully contacts the side of the hinged base 4 near the bottom of the deep hole rock wall, so that the hinged base 4 is fully anchored to the rock wall, thereby improving the anchoring stability of the anchor.

[0026] In some embodiments, the surfaces of the first limiting steel plate 5 and the second limiting steel plate 6 are respectively provided with a plurality of second through holes (not shown in the figure). During the forward movement of the anchor pusher 8, the anchoring agent 11 is squeezed. After the packaging of the anchoring agent 11 is squeezed and ruptured, the anchoring agent leaks out and flows out from the second through holes on the surfaces of the first limiting steel plate 5 and the second limiting steel plate 6, so that the first limiting steel plate 5 and the second limiting steel plate 6 are in full contact with the anchoring agent, and the first limiting steel plate 5 and the second limiting steel plate 6 are in full contact with the deep hole rock wall, thereby improving the anchoring stability.

[0027] In some embodiments, the blocking structure and the anti-detachment structure of the anchor pusher are the same structure. The anti-detachment structure of the anchor pusher is described in detail below.

[0028] See Figure 2 and Figure 3 As shown, the anti-detachment structure 9 of the anchor pusher includes: a first wedge block 12 disposed on the first side of the first limiting steel plate 5, and a second wedge block 13 disposed on the first side of the second limiting steel plate 6, the first wedge block 12 and the second wedge block 13 corresponding to each other; after the anchor pusher 8 passes over the first wedge block 12 and the second wedge block 13 along the wedge-shaped inclined surface of the first wedge block 12 and the second wedge block 13, the first wedge block 12 and the second wedge block 13 prevent the anchor pusher 6 from retracting.

[0029] In this embodiment, the anchor pusher anti-detachment mechanism 9 consists of wedge blocks, which are steel blocks with a boosting ramp. Wedge blocks are welded to the side of the first limiting steel plate 5 facing the second limiting steel plate 6 and the side of the second limiting steel plate 6 facing the first limiting steel plate 5, respectively. The boosting ramp of the wedge blocks faces the anchor pusher 8, and the wedge blocks fixed to the first limiting steel plate 5 and the second limiting steel plate 6 are symmetrical. When the hinged base 4 has not reached the bottom of the deep hole, the first limiting steel plate 5 and the second limiting steel plate 6 are not opened due to the pressure of the rock walls on both sides. At this time, the boosting ramp of the wedge blocks fixed to the opposite sides of the first limiting steel plate 5 and the second limiting steel plate 6 hinders the advancement of the anchor pusher 8. Under the action of thrust, the anchor pusher 8 contacts the boosting ramp of the wedge blocks, pushing the wedge blocks to drive the anchoring agent pushing device 2 forward. When the hinged base 4 reaches the bottom of the deep hole, after the anchor push head 8 passes the wedge block's boosting ramp, the side of the wedge block that contacts the anchor push head 8 no longer has a boosting ramp. When the anchor push head 8 retracts, it encounters resistance, preventing the anchor push head 8 from retracting. At the same time, when the anchor push head 8 passes the wedge-shaped ramp of the first wedge block 12 and the second wedge block 13 during its forward movement, it opens the first limiting steel plate 5 and the second limiting steel plate 6 to contact the inside of the rock wall, improving the stability of the anchor. At the same time, the anchoring agent 11 squeezed in the receiving cavity 7 is released.

[0030] See Figure 2 and Figure 3As shown, in some embodiments, the anti-disengagement structure of the anchor pusher further includes: a third wedge block 14 disposed on the first side of the first limiting steel plate 5, and a fourth wedge block 15 disposed on the first side of the second limiting steel plate 6, the third wedge block 14 and the fourth wedge block 15 corresponding to each other; the third wedge block 14 is closer to the hinge base 4 than the first wedge block 12, and the fourth wedge block 15 is closer to the hinge base 4 than the second wedge block 13; after the anchor pusher 8 passes over the third wedge block 14 and the fourth wedge block 15 along the wedge-shaped inclined surface of the third wedge block 14 and the fourth wedge block 15, the third wedge block 13 and the fourth wedge block 14 prevent the anchor pusher 8 from retracting.

[0031] In this embodiment, the wedge-shaped blocks in the anti-detachment structure 9 of the anchor pusher are steel blocks with a pushing ramp. The first wedge block 12 and the third wedge block 14 are fixed to the side of the first limiting steel plate 5 facing the second limiting steel plate 6, and the second wedge block 13 and the fourth wedge block 15 are fixed to the side of the second limiting steel plate 6 facing the first limiting steel plate 5. The second wedge block 13 and the fourth wedge block 15 are closer to the hinge base 4, and the positions of the wedge blocks are symmetrical. After the anchor pusher 8 passes the first wedge block 12 and the second wedge block 13, the first limiting steel plate 5 and the second limiting steel plate 6... As steel plate 6 unfolds and contacts the rock wall, anchor pusher 8 continues to advance. After passing the third wedge block 14 and the fourth wedge block 15 on the inclined plane, the first limiting steel plate 5 and the second limiting steel plate 6 are pressured by the rock wall and tend to close, squeezing anchor pusher 8 back. The anchor pusher 8, which has a tendency to retreat, is stopped by the side of the third wedge block 14 and the fourth wedge block 15 that are in contact with the anchor pusher 8. At the same time, anchor pusher 8 supports the unfolding of the first limiting steel plate 5 and the second limiting steel plate 6, further increasing the contact area with the rock wall. As anchor pusher 8 advances, it further squeezes anchoring agent 11, causing the packaging bag of anchoring agent 11 to rupture and be released from the receiving cavity 7, improving anchoring stability. The pusher anti-detachment mechanism 9 and anchor pusher 6 can ensure structural stability of anchoring agent pushing device 1 during advancement and anchoring.

[0032] In some embodiments, the same effect can be achieved by using steel blocks with arc-shaped pushing surfaces instead of the wedge-shaped blocks on the first limiting steel plate 5 and the second limiting steel plate 6. Under the action of thrust, the anchor push head 8 advances along the arc-shaped surfaces of the steel blocks located at corresponding positions on the first limiting steel plate 5 and the second limiting steel plate 6. After the anchor push head 8 passes the arc-shaped pushing surfaces of the first and second steel blocks, the first limiting steel plate 5 and the second limiting steel plate 6 unfold. The anchor push head 8 has a tendency to retreat but is prevented from retreating by the first and second steel blocks. After continuing to push the anchor push head 8 past the arc-shaped pushing surfaces of the third and fourth steel blocks, it is prevented from retreating by the third and fourth steel blocks.

[0033] In some embodiments, an anchor pusher limiting protrusion is provided within the V-shaped structure; the anchor pusher limiting protrusion includes: a first limiting protrusion 18 provided on the first side of the first limiting steel plate 5, and a second limiting protrusion 19 provided on the first side of the second limiting steel plate 6, the first limiting protrusion 18 and the second limiting protrusion 19 corresponding to each other; the initial position of the anchor pusher is locked between the limiting structure formed by the first limiting protrusion 18 and the second limiting protrusion 19, and the anti-disengagement structure formed by the first wedge block 12 and the second wedge block 13.

[0034] In this embodiment, rectangular steel blocks fixed to the first limiting steel plate 5 and the second limiting steel plate 6 form a V-shaped inner limiting protrusion. These blocks are respectively fixed to the side of the first limiting steel plate 5 facing the second limiting steel plate 6 and the side of the second limiting steel plate 6 facing the first limiting steel plate 5. The rectangular steel blocks are all fixed at the end furthest from the hinged base 3 and are symmetrically positioned. When the limiting steel plates are closed, they lock the anchor pusher 8, preventing the anchor body 1 from detaching from the anchoring agent pushing device 2 due to pullback when the anchor pusher 8 enters the deep hole, thus increasing the structural stability of the anchor during deep hole advancement.

[0035] In some embodiments, the anchor is an anchor bolt or an anchor cable.

[0036] See Figure 1 and Figure 2 As shown, in some embodiments, the anchor fastening device 3 includes a tray 17 and a lock 16. The tray 17 and the lock 16 are fixed to the second end of the anchor body 1. The lock 16 is connected to the tray 17 and is further away from the end of the anchor pusher 8 than the tray 17.

[0037] In some embodiments, the locking device 16 may specifically be a nut. After being anchored at the first end of the anchor body 1, pressure is applied to the tray 17 through the locking device 16. The tray 17 contacts the rock wall surface and transmits the concentrated force from the locking device 16 evenly to the rock surface.

[0038] In some embodiments, the push connection device 10 is a detachable structure.

[0039] In this embodiment, the pushing connection device 10 has threads at both ends, and a corresponding threaded hole is provided on the side where the anchor push head 8 connects to the pushing device 10. A corresponding threaded hole is also provided on the section where the anchor body 1 connects to the pushing connection device 10. The pushing connection device 10 is threadedly connected to the anchor body 1 and the anchor push head 8. The use of a detachable structure improves the ease of operation.

[0040] In some embodiments, the hinged base 4 is connected to the first limiting steel plate 5 and the second limiting steel plate 6 respectively via hinge shafts, so that the first limiting steel plate 5 and the second limiting steel plate 6 can achieve the state transition between closed and unfolded in the two stages of pushing in and anchoring.

[0041] In some embodiments, the first limiting steel plate 5 and the second limiting steel plate 6 are symmetrically arranged on the side of the hinged base 4 facing the anchor push head 8. The symmetrical arrangement of the first limiting steel plate 5 and the second limiting steel plate 6 on the anchor push head 8 forms a stable structure, reduces resistance during the pushing process, prevents the anchor from shaking or loosening in the anchor cable hole, and enhances the reliability of the anchoring.

[0042] In some embodiments, the anchor is made entirely of metal, which enables the anchor to withstand greater thrust and tension during use without breaking or permanent deformation, thus extending the service life of the anchor.
