Detailed Description
The present application is described in further detail below with reference to figures 1-3.
The embodiment of the application discloses dangerous rock anchor structure. Referring to fig. 1 and 2, the dangerous rock anchoring structure comprises an anchor rod assembly 1, an i-steel 2 and a sliding-resistant key 3.
The bolt assembly 1 is used to provide an anchoring force to the rock wall 4. The I-steel 2 is arranged in the rock wall 4, and the I-steel 2 is used for enabling the anchoring force provided by the anchor rod assembly 1 to the rock wall 4 not to be easily reduced. The anti-sliding key 3 is arranged on the anchor rod component 1, and the anti-sliding key 3 is used for preventing the anchor rod component 1 from falling off from the rock wall 4.
The anchor rod assembly 1 comprises an anchor rod 11 and a steel backing plate 12. An anchor hole 41 is cut in the rock wall 4. After the anchor rod 11 is inserted into the anchor hole 41, cement mortar is poured into the anchor hole 41 to fix the anchor rod 11.
The end of the anchor rod 11 close to the rock wall 4 is provided with a retaining piece 42, and the retaining piece 42 is formed by enlarging the aperture of the end of the anchor hole 41 far from the steel backing plate 12 by a reamer and pouring cement mortar. The side of the backstop 42 adjacent the pad 12 abuts the rock wall 4 so that the bolt assembly 1 is not easily separated from the rock wall 4.
The steel backing plate 12 is sleeved at one end, far away from the rock wall 4, of the anchor rod 11, one end, far away from the steel backing plate 12, of the anchor rod 11 is bent to form a right-angle corner, and the right-angle corner is welded on one side, far away from the rock wall 4, of the steel backing plate 12, so that the steel backing plate 12 is fixed on the anchor rod 11.
Referring to fig. 2 and 3, the steel shim plate 12 is provided with an abutment 121 on the side thereof adjacent the rock wall 4. The abutting part 121 is obliquely arranged at one end of the steel shim plate 12 close to the anchor rod 11, the high end of the abutting part 121 is one end far away from the anchor rod 11, and the high end of the abutting part 121 is fixed on the steel shim plate 12; the lower end of the abutment portion 121 is the end close to the anchor rod 11, and the lower end of the abutment portion 121 is embedded in the anchor hole 41. When the ground produces vibrations and the rock mass has a tendency to move in a direction away from the rock wall 4, so that the abutment 121 is further embedded in the anchoring hole 41, thereby enhancing the anchoring force provided by the anchoring assembly to the rock wall 4.
Referring to fig. 2, one end of the anchor hole 41, which is far away from the rock wall 4, is provided with mounting grooves 43, the mounting grooves 43 are arranged at both sides of the anchor rod 11, and the distance between the side wall of the mounting groove 43, which is far away from the anchor rod 11, and the anchor rod 11 is greater than the distance between the anchor rod 11 and the side wall of the anchor hole 41. The I-steel 2 is vertically arranged in the mounting groove 43, one end of the I-steel 2 is abutted with the rock wall 4 on the side, away from the steel backing plate 12, of the mounting groove 43, and the other end of the I-steel 2 is abutted with the side wall, close to the anchor hole 41, of the abutting portion 121. Placing the I-steel 2 into the mounting groove 43, and pouring cement mortar into the mounting groove 43 to form a cement mortar layer, so that the I-steel 2 in the mounting groove 43 is firmly fixed in the mounting groove 43; and after cement mortar is poured into the mounting groove 43, the mounting groove 43 is not easy to collapse.
Because the rock mass of the inside of cliff 4 is difficult for being contacted with water or air in the rock mass on cliff 4 surface for the rock mass that I-steel 2 is close to cliff 4 one end receives the influence of water and air less, so that this rock mass structural strength is stronger, thereby I-steel 2 can effectively firm support steel tie plate 12, and then reach the purpose that makes anchor bolt subassembly 1 be difficult for reducing to the anchor power that cliff 4 provided. And the I-steel 2 is further embedded into the anchor hole 41 at the abutting part 121, and the I-steel 2 is extruded by the abutting part 121, so that the I-steel 2 is more firmly abutted against the side wall of the mounting groove 43, and the anchoring force provided by the anchoring assembly to the rock wall 4 is further enhanced.
Referring to fig. 2 and 3, the anti-sliding key 3 is arranged on one side of the steel backing plate 12 far away from the rock wall 4, the anti-sliding key 3 is a circular plate, and the cross-sectional area of the anti-sliding key 3 is larger than that of the steel backing plate 12. And a fastening bolt 31 penetrates through one side of the anti-sliding key 3, which is far away from the rock wall 4, and the small end of the fastening bolt 31 penetrates through the anti-sliding key 3 and is in threaded connection with the steel backing plate 12. The slide resistant key 3 is fixed to the steel shim plate 12 by tightening the fastening bolt 31.
One side that anti-skidding key 3 is close to cliff 4 is equipped with toper arch 32, and toper arch 32 inlays and establishes in cliff 4 to make anti-skidding key 3 fix in cliff 4, thereby strengthen the relation of being connected between anti-skidding key 3 and the cliff 4, and then make the stock subassembly 1 with anti-skidding subassembly fixed connection be difficult for separating with cliff 4.
Referring to fig. 1, a concrete layer 5 is laid on the side of the steel tie plate 12 away from the rock wall 4, and is formed by pouring concrete on the rock wall 4. The anchor rod assembly 1 is sealed through the concrete layer 5, so that the anchor rod assembly 1 is not easy to rust due to long-time contact with air; and the concrete layer 5 reinforces the surface of the rock wall 4, so that rock mass on the surface of the rock wall 4 is not easy to fall off from the rock wall 4.
In order to make the anti-skidding key 3 more firm inlay establish in concrete layer 5, one side that anti-skidding key 3 kept away from cliff 4 is fixed with reinforcement 33, and reinforcement 33 includes the rectangular plate of two, and the equal vertical setting of two rectangular plates, and two rectangular plate mutually perpendicular and intersect. The reinforcing member 33 is embedded in the concrete layer 5, and the side wall of the reinforcing member 33 is abutted against the concrete layer 5, so that the purpose that the anti-sliding key 3 is embedded in the concrete layer 5 more firmly is achieved.
The construction principle of the dangerous rock anchoring structure of the embodiment of the application is as follows: firstly, an anchor hole 41 is formed in the rock wall 4, an end of the anchor hole 41 close to the rock wall 4 is reamed by using a reamer, and then an installation groove 43 is formed in an end of the anchor hole 41 far away from the rock wall 4.
Then inserting the anchor rod 11 into the anchor hole 41 and inserting and fixing the i-steel 2 into the mounting groove 43, and then pouring cement mortar into the anchor hole 41 and the mounting groove 43 to fix the anchor rod 11 in the anchor hole 41; the I-shaped steel 2 is fixed in the mounting groove 43; and the cement mortar at the end of the anchor rod 11 close to the rock wall 4 is solidified to form the retaining member 42.
After the cement mortar is solidified, the steel backing plate 12 is sleeved on the anchor rod 11, so that the abutting part 121 on the steel backing plate 12 abuts against one end, away from the rock wall 4, of the I-steel 2, one end, away from the rock wall 4, of the anchor rod 11 is bent to form a right-angled corner, and the corner is welded on one side, away from the rock wall 4, of the steel backing plate 12. The anti-slide key 3 is fixed on the steel backing plate 12 through the fastening bolt 31, and the tapered protrusion 32 on the anti-slide key 3 is embedded into the rock wall 4.
Finally concrete is poured on the side of the anchor assembly 1 remote from the rock wall 4 to form a concrete layer 5. And seal the anchor subassembly through concrete layer 5 for the anchor subassembly is difficult for contacting with the outside air for a long time and leads to rustting, and concrete layer 5 consolidates the cliff 4 surface, so that the rock mass on cliff 4 surface is difficult for droing from cliff 4.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
