The working principle of the utility model are as follows: as shown in Figure 2-5, when burying, three blades are in closed state anchor pole
Three blades 9 of anchor head are unfolded three vanes mechanical tension at anchor head in the soil body, as Figure 6-9, mutually sting with the soil body
It closes, forms end bite force, three blades are embedded in the soil body, form anchor pole carrying using three bite forces between blade and soil layer
Power, the power are that resistance is held at end, are the major anchorage power of self-opening type machinery anchor pole.
In addition after the completion of tensioning, after in cement mortar injection hole, the frictional force between grouting rock bolt and the soil body is formed,
This power is frictional resistance.Resistance and frictional resistance collective effect are held by end, form the soil bearing capacity of self-opening type anchor pole.
Specifically: spring pushes slide hinge block, allows blade to keep certain and is flared out dynamics, is installed in place in hole
Afterwards, anchor head is pulled up, blade penetrates the hole wall soil body, continues drawing until blade opens completely.
In the present embodiment:
Construction technology: hole bit identification sets up operation at sea platform, and drilling machine is in place, drills, and divides into Grouting Pipe and anchor pole, draws
It pulls out, puts and locked after opening to locking pulling force, slip casting, sealing of hole, concreting anchorage.
Important technological parameters:
A major axis diameter 29.5mm, length 550mm
B length of blade 220mm, width 70mm/30mm
C slide hinge block stroke 143mm
D anchor head closes up outer diameter 120mm
E anchor head opens outer diameter 530mm
Maximum anchor force 6t in the f soil body, after anchoring load losses, minimum anchor force 2t
To meet the fully effective opening of mechanical anchor head, and enough bite forces are formed with stratum, so the pattern anchor
Bar requires stratum not only to meet the embeddable soil body of mechanical three blade of anchor head, but also the soil body is required to have certain yield strength, with
Clay rock and the sandy gravel soil body are best.
After drilling machine pore-forming, anchor pole is sent into hole, mechanical anchor head is in close up shape, anchor during being sent into the soil body
After head reaches designated depth, the tensioning to outside hole, crossing in tensioning with middle three blade of anchor head is gradually in opening type, final three blades insertion
In the soil body, it is mutually twisted with the soil body.
In the present embodiment: according to this engine request, anchor pole is angled downward in 40 °, and mechanical anchor head, which passes through, infers slip circle, anchor pole
Valid bonding length is not less than 10m, bolt diameter 28mm.(2) drill
It drills after adjusting drilling machine angle using geological drilling rig, aperture 130mm, hole depth 12m.
Drilling discloses strata condition, and: 0-2m is loam layer, 2-8m be sandy gravel and loam alternating layers, folder land pebble lenticular body and
Cobble adhesive bond, 8-12m are clay rock bed.
After the completion of drilling, to avoid collapsing in hole, anchor pole is sent into hole in time after pore-forming.
(3) tensioning
1. machine drawing has
Punching jack 28mm lockset 65cm diameter thickness 12mm bearing plate anchor pole reinforcing rib meter
2. aperture is manually whittled into the burnishing surface vertical with hole, after anchor pole and reinforcing rib meter are sent into hole, fixed bearing plate,
Jack and lockset are installed.
3. grading tension is carried out using the Pyatyi stage, based on predetermined maximum anchor force F=60KN, respectively with 0.1F, 0.5F,
0.75F, 1F, 1.2F carry out tensioning.It is as shown in table 1:
4. practice have shown that anchor pole is basicly stable to hole outer displacement after pulling anchor cable stage reaches 0.5F, after reaching locking condition,
Hole outer displacement overall length is between 0.5~1.2m, hole depth 12m, and after locking, effective rock-bolt length is greater than 10m, meets design requirement.
It is proved through this project Successful Practice, the advantages of self-opening type machinery anchor pole set grouting rock bolt and enlarged footing anchor pole,
Anchor force is big, reinforces fast, is suitable for land pebble and soil layer is reinforced.
This equipment combines the reapective features of grouting rock bolt and enlarged footing anchor pole, forms friction-type+end and holds type anchor pole, both utilized
The soil body thus can be significantly even more using the bite force of three blades of anchor head and ground layer soil body to the frictional force of mortar anchoring section
Increase anchor force of the anchor pole in the soil body.
The above is only the preferred embodiment of the utility model for the utility model offer, it is noted that for this skill
For the those of ordinary skill in art field, without departing from the principle of this utility model, can also make it is several improvement and
Retouching, these improvements and modifications should also regard the protection scope of the utility model.
