Description
Technical field
This utility model is related to Hydraulic and Hydro-Power Engineering technical field, more particularly, to a kind of deep hole grouting rock bolt collar plate shape pair
Medium-height trestle structure.
Background technology
In the engineering slope stabilization and reinforcement of water conservancy and hydropower station, grouting rock bolt is a kind of more universal support pattern, general to unite
Grouting rock bolt installs anchor pole (3) in hole (2) as shown in figure 1, its technical scheme is mainly drills (2) in side slope (1),
Mortar is filled between hole (2) and anchor pole (3) in cavity, mortar is the power transmission medium between anchor pole and side slope.The stress of anchor pole is
Mortar is delivered load to by side slope, mortar passes to anchor pole, after rockbolt stress, resistance is passed to into mortar again, mortar is again
Side slope is passed to, and the purpose for reaching bolt anchorage side slope is circulated by this, so, the stressed effect and mortar chymoplasm of anchor pole
Can amount, be to ensure the key that play one's part to the full of anchor pole.When rock-bolt length is longer, under the Gravitative Loads of anchor pole, anchor pole
Curved state (as shown in Figure 1), the anchor pole back segment body of rod can be contacted with hole wall, and now, mortar is difficult to fully wrap up anchor pole, anchor
Bar stress is poor, reduces significantly the supporting effect of anchor pole, it is also possible to cause slope instability.
Utility model content
The purpose of this utility model be in order to solve rock-bolt length it is longer when as Gravitative Loads cause anchor pole in bolthole
In curved state cause the anchor pole back segment body of rod to contact with hole wall, the problem for making mortar be difficult to fully wrap up anchor pole, there is provided
Plant deep hole grouting rock bolt collar plate shape centering supporting structure.
This utility model is achieved by following technical solution：
A kind of deep hole grouting rock bolt collar plate shape centering supporting structure, the structure is for anchor pole centering is fixed in side slope
In bolthole, it be included in arrange on the outer wall of anchor pole to medium-height trestle, this pair of medium-height trestle is with collar plate shape made by steel plate
Frame, this pair of medium-height trestle are made up of the slurry hole of altering no less than four on a disk and disk, and disk is solid by weld part welding
It is scheduled on anchor pole.
On anchor pole every 2～4m one collar plate shape of spacing interval setting to medium-height trestle.
The thickness of the disk is not less than 2mm.
Radius of the radius of the disk less than bolthole.
It is described to alter slurry the ring on disk is uniformly arranged with the position of anchor pole as axle in hole.
The radius for altering slurry hole is the 1/10～1/30 of disc radius.
The beneficial effects of the utility model：This utility model is by welding a kind of arc of support anchors on anchor pole
Frame, reaches anchor pole purpose placed in the middle in hole, is effectively prevented the flexural deformation under Gravitative Loads of long anchor pole and is close to petrosal foramen side
Wall, by arranging to medium-height trestle, can make anchor pole straight in petrosal foramen, and mortar can uniformly wrap up anchor pole, improve anchor pole
Stress condition, improves anchoring effect.This utility model structural shape is simple, easy construction, strong applicability, with preferable Jing
Ji advantage.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
Referring initially to Fig. 1, Fig. 1 illustrates the existing deep hole grouting rock bolt schematic diagram without centering structure；It can be seen that
As anchor pole 3 is not provided with centering structure, after the bolthole 2 in the insertion side slope 1 of anchor pole 3, due to effect of weight, after anchor pole 3
Half section can nature to tenesmus, cause the bending of anchor pole 2, make mortar 4 be difficult to completely envelope anchor pole 2, so as to dotted line in FIG
The B areas of frame scope form the poor area of rockbolt stress.
In view of the foregoing, this utility model has carried out such improvement, as shown in Fig. 2 in bolthole 2, along anchor
The trend of bar 3, just arranges one group to medium-height trestle 5 at interval of a segment distance, by the outer support structure to medium-height trestle 5, makes anchor pole 3 exist
It is fixed in bolthole 2, then passes through mortar 4 again to anchor pole 3 and medium-height trestle 5 is coated, reliably receive so as to be formed
Power structure.
As shown in figure 3, it is of the present utility model it is this be disc-shape to medium-height trestle 5, and anchor pole is welded on by weld part 6
On 3, and form outer support structure.As shown in figure 4, this pair of medium-height trestle 5 is mainly made up of the altering slurry hole 7 on disk and disk, alter
Slurry hole 7 is uniformly arranged in ring with the center of circle of disk on disk as axle, and the number that slurry hole 7 is altered in Fig. 4 is 4, in addition, the circle
The radius of disk should be less than the radius of bolthole 2.
As shown in figure 5, this pair of medium-height trestle 5 is, with collar plate shape support made by steel plate, the thickness of the disk, generally should not
Less than 2mm, it is advisable with 2～4mm, the internal diameter for altering slurry hole 7 can should be flowed freely by the hole beneficial to mortar 4.
This utility model is implemented：
As shown in Fig. 2 first, the drilling in side slope 1 forms bolthole 2, makes centering using the welding of disk shape steel plate
Frame 5 being drilled with disk alters slurry hole 7, medium-height trestle 5 will be welded on anchor pole 3 by weld part 6 and be squeezed in bolthole 2,
Then perfusion mortar 4 is closed, and mortar 4 reaches the bottommost of bolthole 2 successively by altering slurry hole 7.
The patterns such as dowel beam of the anchor pole of the present utility model 3 comprising 3 or many compositions of anchor pole 3 of single anchor rod.
Certainly, it is more than concrete application example of the present utility model, this utility model also has other embodiments, all
The technical scheme formed using equivalent or equivalent transformation, is all fallen within the protection domain required by this utility model.
