Abstract
The invention discloses an anchor rod for strengthening tunnels, which comprises a rod body in a curve shape along the axial direction. According to the anchor rod in the embodiment of the invention, the rod body is in the curve shape to increase the stretching variation rate of the rod body of the anchor rod, and when rock mass is deformed, the anchor rod can absorb the large kinetic energy in the rock mass by generating large deformation, so that the damage of the rock mass is reduced, and the stability of the tunnels is ensured.
Description
Technical field
The present invention relates to a kind of field of mining, especially relate to a kind of anchor pole that the tunnel reinforces that is used for.
Background technology
Under the existing ore deposit after the tunnelling, can form the outside all around on sidewall and the roof near the rock stratum ravel area in tunnel be positioned at the rock stratum compact zone of ravel area inboard,, be easy in lane space, push, even can cave in because the rock stratum of ravel area is comparatively loose.
Therefore, the tunnel sidewall need can play and reinforce arching action and suspention effect by bolt support, makes the rock stratum of each sidewall of tunnel and anchor pole be tightened to one so-called " compound beam ", thereby improves the stability in tunnel.
Existing anchor pole device is generally straight-bar, after straight anchor pole anchors in the sidewall of tunnel, when surrouding rock deformation is big, is pulled to the plastic strain stage owing to the deformability of straight anchor pole is less, and loses support action, thereby the tunnel is destroyed.
Summary of the invention
The present invention is intended to solve at least one of technical problem that exists in the prior art.For this reason, one object of the present invention is to propose a kind of a kind of support anchor rod that adapts to the big country rock of heavily stressed distortion.
The anchor pole that the tunnel reinforces that is used for according to the embodiment of the invention comprises the body of rod, the curved vertically shape of the described body of rod.
Anchor pole according to the embodiment of the invention, by the body of rod is set is curve shape, increased the stretching rate of change of the body of rod of anchor pole, this kind anchor pole is by producing bigger distortion when rock mass deformation, can absorb kinetic energy bigger in the rock mass, thereby reduce the destruction of rock mass, thereby guaranteed the stability in tunnel.
In addition, also have following additional technical feature according to anchor pole of the present invention:
In one embodiment of the invention, the described anchor pole that is used for the tunnel reinforcing further comprises supporting plate, and described supporting plate is connected the described body of rod one end.
Wherein, an end of the described supporting plate and described body of rod welding.
In another embodiment of the present invention, an end of the described body of rod extends on straightway and the described straightway and is formed with straight thread.
Wherein, the described anchor pole that is used for the tunnel reinforcing further comprises supporting plate, and described supporting plate bolt is connected on the described straightway.
Alternatively, the described body of rod is level and smooth curve shape.
Further preferably, the described body of rod is sinusoidal, can make the deformable performance of anchor pole best.
Additional aspect of the present invention and advantage part in the following description provide, and part will become obviously from the following description, or recognize by practice of the present invention.
Description of drawings
Above-mentioned and/or additional aspect of the present invention and advantage are from obviously and easily understanding becoming the description of embodiment in conjunction with following accompanying drawing, wherein:
Fig. 1 is the schematic diagram according to the anchor pole that is used for the tunnel reinforcing of the embodiment of the invention; And
Fig. 2 is the schematic diagram during according to being used for anchor pole that the tunnel reinforces and reinforcing in the tunnel of the embodiment of the invention.
The specific embodiment
Describe embodiments of the invention below in detail, the example of described embodiment is shown in the drawings, and wherein identical from start to finish or similar label is represented identical or similar elements or the element with identical or similar functions.Below by the embodiment that is described with reference to the drawings is exemplary, only is used to explain the present invention, and can not be interpreted as limitation of the present invention.
In description of the invention, term " inboard ", " outside ", " on ", close the orientation of indications such as D score, " top ", " end " or position is based on orientation shown in the drawings or position relation, only be the present invention for convenience of description rather than require the present invention therefore can not be interpreted as limitation of the present invention with specific orientation structure and operation.
Below with reference to be used for the anchor pole that tunnel reinforce of Fig. 1 description according to the embodiment of the invention.
As shown in Figure 1, the anchor pole 1 that the tunnel reinforces that is used for according to the embodiment of the invention, comprise the body of rod 11, the curved vertically shape of the body of rod 11, when roadway surrounding rock generation moderate finite deformation, the curve shape of anchor pole can adapt to this situation, and the longitudinal strain by anchor pole self can absorb kinetic energy bigger in the rock mass, and keeps the support capacity of anchor pole 1 not slackened.
Alternatively, the body of rod 11 is level and smooth curve shape.Further preferably, the body of rod 11 is sinusoidal, can make the deformable performance of anchor pole best.
In one of them embodiment of the present invention, anchor pole 1 further comprises supporting plate 12, and supporting plate 12 is connected the body of rod 11 1 ends, and this supporting plate 12 welds (scheming not shown) with an end of the body of rod 11.
In another embodiment of the present invention, as shown in Figure 1, an end of the body of rod 11 extends on straightway 13 and the straightway 13 and is formed with straight thread, is chosen as the roll extrusion straight thread.Anchor pole 1 further comprises supporting plate 12, and supporting plate 12 is connected on the straightway 13 by bolt.
By supporting plate 12 is set, can further increase the anchoring effect of anchor pole 1, and below with reference to the tunnel reinforcement means of Fig. 2 introduction according to the embodiment of the invention, wherein, the sidewall in tunnel and roof comprise ravel area A that is positioned at close tunnel, the outside and the compact zone B that is positioned at ravel area A inboard, as shown in Figure 2.
Tunnel reinforcement means according to the embodiment of the invention may further comprise the steps:
(1) form a plurality of borings 2 in the sidewall in tunnel and roof, boring 2 runs through ravel area A and stretches in the compact zone B;
(2) anchor pole of describing in a plurality of the foregoing descriptions 1 is inserted respectively in a plurality of borings 2, and an end of the body of rod 11 stretches out outside sidewall and the roof;
(3) the cement injection mortar solidifies portion 3 with formation in boring 2, and solidifying portion 3 can be fixed on anchor pole in the country rock, makes anchor pole play anchorage effect; And
(4) end that stretches out sidewall and roof at anchor pole 1 is connected supporting plate 12.Alternatively, supporting plate 12 can lean against on the sidewall and roof in tunnel.
A plurality of anchor poles 1 can be evenly distributed in tunnel sidewall and the roof.In an example of the present invention, the spacing with 1m * 1m on tunnel sidewall and roof evenly distributes.Like this, can evenly ravel area A be anchored on the compact zone B, thereby the sidewall all around and the roof that can farthest prevent the tunnel push in the space in tunnel.
According to the anchor pole of the embodiment of the invention, be curve shape by the body of rod is set, increased the stretching rate of change of the body of rod, this kind anchor pole is by producing bigger distortion when rock mass deformation, can absorb kinetic energy bigger in the rock mass, thereby reduce the destruction of rock mass, thereby guarantee the stability in tunnel.
