Such as, on the same body of rod 11, three first expansion bodies 12 are arranged at the rock anchorage interval section 11a, and two second expansion bodies 13 are in coagulation
The setting of the interval native anchoring section 11b.
Optionally, in a kind of embodiment in the cards, first, which expands body 12, includes multiple first expansion parts, Duo Ge
One expansion part is fixed on the periphery of the body of rod 11 around the axis of the body of rod 11.
Wherein, multiple first expansion parts are fixed on the periphery of the body of rod 11 around the axis of the body of rod 11, that is, multiple first expansion parts
In the radial direction of the body of rod 11, when being that entirety is treated with rock anchorage section 11a, in the first expansion part energy of radial direction setting
Enough cross-sectional areas for effectively increasing rock anchorage section 11a, to effectively increase rock anchorage section 11a and anchoring body
Contact area.
It should be noted that the quantity of the first expansion part can be the quantity such as two, three, four, five.
In the present embodiment, Fig. 2 is referred to, Fig. 2 shows the specific structures that in the present embodiment first expands body 12.
First expansion part is reinforcing bar 12a, and the quantity of the first expansion part is four, that is, the quantity of reinforcing bar 12a is four, four
A reinforcing bar 12a is welded in the periphery of the body of rod 11 around the axis of the body of rod 11, in other specific embodiments, can also for two or
Three or four equal reinforcing bars 12a are welded in the periphery of the rock anchorage section 11a of the body of rod 11 around the axis of the body of rod 11.
Wherein, using multiple reinforcing bar 12a as the first expansion part, enable multiple reinforcing bar 12a solid around the axis of the body of rod 11
It is scheduled on the periphery of the body of rod 11.Wherein, easily fabricated since reinforcing bar 12a is at low cost, therefore the first expansion body is constituted with multiple reinforcing bar 12a
12, conducive to the popularization and use of rock mass anchor pole 10.
It should be noted that due to needing that there are gaps between the first expansion body 12 and the inner wall of anchor hole, therefore, which can be with
It is formed by the gap between two adjacent reinforcing bar 12a, also or between the periphery and anchor hole of reinforcing bar 12a there are gaps.
It should be noted that the second expansion body 13 includes multiple second expansion parts, axis of multiple second expansion parts around the body of rod 11
Line is fixed on the periphery of the body of rod 11.
Wherein, multiple second expansion parts are fixed on the periphery of the body of rod 11 around the axis of the body of rod 11, that is, multiple second expansion parts
In the radial direction of the body of rod 11, when being that entirety is treated with concrete anchoring section 11b, in the second expansion part of radial direction setting
The cross-sectional area of rock anchorage section 11a can effectively be increased, to effectively increase concrete anchoring section 11b and anchoring
The contact area of body.
It should be noted that the second expansion part is reinforcing bar 12a in the present embodiment.Likewise, second expands in the present embodiment
The quantity for opening part is four, that is, the quantity of reinforcing bar 12a is four, and four reinforcing bar 12a are welded in the body of rod 11 around the axis of the body of rod 11
Periphery can be also two or three or four equal reinforcing bars 12a around the axis of the body of rod 11 in other specific embodiments
It is welded in the periphery of the concrete anchoring section 11b of the body of rod 11.
Wherein, the present embodiment also provides a kind of construction method of rock mass anchor pole 10 comprising:
It constructs on rock mass anchor hole;
The rock anchorage section 11a of the above-mentioned rock mass anchor pole 10 provided is put into anchor hole;
The grout injection into anchor hole;
The position for adjusting the water string 14 being set on the body of rod 11 of rock mass anchor pole 10 makes one end position of water string 14
In in anchor hole, the other end of water string 14 is located at outside anchor hole;
The grout injection into water string 14;
The casting concrete on rock mass makes concrete bury the concrete anchoring section 11b of rock mass anchor pole 10.
Wherein, it is constructed by the construction method of rock mass anchor pole 10, enables to rock mass anchor pole 10 effectively to connect mixed
Solidifying soil and rock mass.Wherein, the first expansion body 12 and the second expansion body 13 are capable of increasing the contact area between the body of rod 11 and anchoring body, from
And the bigger anchor force that the more existing anchor pole of rock mass anchor pole 10 is provided.Meanwhile it being used in this construction method anti-
Jacket pipe 14, and fill cement slurry in water string 14 and shut opening floating, water string 14 is kept away
Exempt from water to flow between the body of rod 11 and anchoring body, leads to the case where loosening between the body of rod 11 and anchoring body.
Referring again to Fig. 1, rock mass anchor pole 10 provided in this embodiment further includes water string 14, and water string 14 is arranged
In the junction of rock anchorage section 11a and concrete anchoring section 11b.
It should be noted that in other specific embodiments, first, which expands body 12, expands part 20, plate-like for plate-like referring to Fig. 3
Expand part 20 and is arranged in the body of rod 11.Second, which expands body 13, expands part 20 for plate-like, and plate-like expands part 20 and is arranged in the body of rod 11.Wherein, plate-like expands
Part 20 is threaded through on the body of rod 11 as the first expansion body 12 and the second expansion body 13, can be effectively increased rock anchorage section 11a, be mixed
Solidifying contact area between soil anchoring section 11b and anchoring body.It should be noted that due to first expand body 12 and anchor hole inner wall it
Between need there are gap, in Fig. 3 as can be seen that the plate-like as the first expansion body 12 expands part 20 in order to being contained in anchor hole simultaneously
There are gap between anchor hole, it is less than the plate-like for expanding body 13 as second and expands part 20.
It should be noted that referring to fig. 4, in other specific embodiments, the second expansion part is dendritic expansion part 30, dendritic
Expand that part 30 favours the axis of the body of rod 11 and the periphery of the body of rod 11 is fixed in one end.
Wherein, dendritic to expand that part 30 favours the axis of the body of rod 11 and the periphery of the body of rod 11 is fixed in one end, that is, with concrete
Anchoring section 11b is whole when treating, concrete anchoring section 11b in the radial direction, dendritic expansions part 30 and the common limit of the body of rod 11
Determine concrete anchoring section 11b and anchoring body contact surface in the radial direction, that is, its contact area radially is effectively promoted,
On the axial direction of concrete anchoring section 11b, dendritic expansion part 30 is due to being obliquely installed, in the axial direction, on dendritic expansion part 30 not
The contact surface between anchoring body of the concrete anchoring section 11b radially at different distance also can be effectively promoted with position
Product.
The foregoing is merely preferred embodiment of the present application, are not intended to limit this application, for the skill of this field
