Specific embodiment
The utility model is further described with embodiment with reference to the accompanying drawing.
As shown in Fig. 1-2,4: a kind of communication pole and tower foundation using self-locking anchor bar, including lithosphere 11, in lithosphere 11
It is equipped with plain concrete cushion layer 14, and the top of plain concrete cushion layer 14 is provided with cushion cap 15, is equipped at the middle part of cushion cap 15
The concrete column cap 16 of cushion cap 15 is protruded, concrete column cap 16 stretches out the ground connection that terrace is outer and is located in concrete column cap 16 upwards
Band steel tap 17 and sill anchor 18 are stretched out outside concrete column cap 16 upwards；Rock pore 12 in lithosphere 11 includes straight hole
8 and 8 bottom end of straight hole reaming 9, rock pore 12 around concrete column cap 16 be arranged, be downwardly into the self-locking anchor bar 13 of rock pore 12
Including anchor head 1 and anchor post 2, anchor head 1 is fallen into reaming 9 and anchor post 2 is located in straight hole 8, the rock pore after self-locking anchor bar 13 is arranged
Mortar is perfused in 12；Self-locking anchor bar 13 around concrete column cap 16 be arranged, and the top of the vertical section of L shape self-locking anchor bar 13 and
Horizontal segment is embedded in cushion cap 15.
As shown in figure 3, anchor head 1 includes dilating sleeve 3 and solid reverse taper 4, which is tied up by connector 6
It is scheduled on and dilates on sleeve 3, which is fixedly connected with anchor post 2, and the lower part barrel edge for dilating sleeve 3 dilates set
The axial of cylinder 3 cuts and is rendered as horn-like, and the lower part for dilating sleeve 3 is cut into the arc strip shape body that quantity is not less than four pieces
7, top and the solid reverse taper 4 that the horn-like cavity constituted is used to accommodate solid reverse taper 4 are opened in 7 lower end of arc strip shape body
There are space 5 is dilated between top and the top of horn-like cavity, the height for dilating space 5, which is not less than, dilates 3 lower part of sleeve
The half height of horn-like cavity.In said structure, it is 32/25/40 surface with externally threaded that anchor post 2, which uses diameter,
HRB400 reinforcing bar is made, and dilates sleeve 3 and is made of Q235 steel, the top for dilating sleeve 3 offer can under anchor post 2
The threaded hole being threadedly coupled is held, and is connect in the end of the vertical section of the anchor post 2 of inverted L-shaped with the screw top for dilating sleeve 3；Even
Fitting 6 uses thin wire, and thin wire is to be fixed temporarily the tool for dilating sleeve 3 Yu solid reverse taper 4, make solid reverse taper 4 and
It is not scattered when colliding rock stratum.
As shown in figure 3, self-locking anchor bar before use, first in lithosphere 11 with normal drill bit drill straight hole 8 to projected depth, so
After use reaming bit instead bottom hole be extended to countersinking 9, then the self-locking anchor bar 13 of anchor head 1 will be installed and be inserted into rock pore 12
In, the 7 distending dilated diameter of arc strip shape body of anchor head 1 is finally made under the action of axis pressure, increases arc strip shape body 7 and rock
The bite force of 12 hole wall of hole is realized self-locking and pours into inorganic bonding mortar, this further enhances the anchoring strength of self-locking anchor bar.
The self-locking anchor bar 13 used in the communication pole and tower foundation combines the advantages of mechanical anchoring and anchoring of cementing formula, so-called mechanical
Anchoring relies on frictional force and shearing force between anchor pole and rock to anchor to realize；Cementing formula rely on cementing agent with rock and
Bond between anchor pole anchors to realize, two kinds of anchorage styles are effectively combined together by self-locking anchor bar.
The utility model constitutes self-locking anchor bar 13 by the way that anchor head 1 is arranged in the lower end of anchor post 2, and has loudspeaker by lower part
Shape cavity dilates sleeve 3 and the composition anchor head 1 of solid reverse taper 4, so that the self-locking anchor bar 13 is applied on communication pole and tower foundation
When, in addition to the bonding of mortar is there are also the physics locking between 9 hole wall of anchor head 1 and reaming, substantially increase the anti-of self-locking anchor bar 13
Pull out reliability；Through calculating, under the conditions of same equal aperture, hole depth, self-locking anchor bar 13 improves about twice than conventional anchor theory resistance to plucking value,
Safety stock surplus is sufficient；And project amount reduces obvious, construction cost reduction by 34% or so when communication pole and tower foundation construction, and
Tower is got over high cost reduction and is more obvious.
Above embodiments are only to illustrate the technical idea of the utility model, and the protection model of the utility model cannot be limited with this
Enclose, it is all according to the utility model proposes technical idea, any changes made on the basis of the technical scheme each falls within this reality
Within the scope of novel protected；The technology that the utility model is not directed to can be realized by the prior art.
