As shown in figure 5, on the other hand the utility model provides the pier shaft anchor ear 8 containing above-mentioned anchoring ring drops system, wrap
Anchoring ring, the first wirerope 9, the second wirerope 10, snap ring 11 and two hoist engines 7 are included, the anchoring ring setting is embraced in pier shaft
8 top of hoop；The left anchoring semi-ring 1 of anchoring ring can be aligned with the seam crossing of pier shaft anchor ear 8 with right anchoring 2 seam crossing of semi-ring and set
It sets.
One end of first wirerope 9 is connect with the hoist engine 7 being placed on the ground, and 9 other end of the first wirerope is around fixed
It is connect after pulley 6 with snap ring 11；Second wirerope, 10 one end is connect with snap ring 11, and the lifting point on one end and pier shaft anchor ear 8 connects
It connects.The quantity of second wirerope 10 and the quantity of lifting point are adapted.When Specific construction, patch weldering is enclosed at 8 suspension centre of pier shaft anchor ear
Welding steel plate prevents from deforming at suspension centre.Second wirerope 10 can be set according to lifting point quantity original on pier shaft anchor ear 8.It is several
One end of a second wirerope 10 is connect with snap ring 11.The two sides of pier shaft anchor ear 8 dismantle, land simultaneously, ensure that whole
Construction safety.
Specific step is as follows for construction method:
Step 1, processing and fabricating assembly anchoring ring；Left anchoring semi-ring 1, right anchoring semi-ring 2 are made of Q235 steel plate, thick
Degree is 12mm, is highly 160mm.Before use, also needing to check that fixed pulley 6 ensures that Anti-hook releasing device works normally.
Step 2, anchor ear disassembly belong to the biggish part-to-item project of risk, and therefore, anchoring ring must unload before
Fall simulation test；Levelling of the land is selected, transport easily has constructed to finish and carried out dropping simulation test at pier stud, will dismantle pier
Body anchor ear 8 is installed on pier shaft lower part from the ground at 1m, and anchoring ring, which is mounted on, has dismantled 8 top appropriate location of pier shaft anchor ear.Simulation
On-site actual situations are dismantled.
Step 3 sets up bracket as pier shaft anchor ear 8 by code requirement and dismantles platform, the appropriate position above pier shaft anchor ear 8
Set installation anchoring ring；Cushioning 5mm rubber pad is tight as required using Electric torque wrench with increasing friction force between anchoring ring and pier shaft
Fixing bolt, it is 82.2KN that high-strength bolt offer, which axially fastens power P,.Certainly, under different execution conditions, the size of power is axially fastened
It is different.Stiffening plate is welded on original suspension centre of pier shaft anchor ear.
Hoist engine 7 is fixed on ground and counterweight is arranged or is anchored using earth anchor, prevents from rolling up during dropping by step 4
Raise the displacement of machine 7；
Step 5 installs the first wirerope 9 and the second wirerope 10；First wirerope 9 and the second wirerope 10 and snap ring
11 connections.
Note: the installation number of the second wirerope 10 can be identical as the lifting point quantity on pier shaft anchor ear 8 or passing through
Cross the quantity of the second wirerope of appropriate adjustment 10 after calculating.Installation settings mode as shown in Figure 4 can be used: that is, pier shaft is embraced
8 sides are bound round there are four lifting point, have mounted three second wirerope 10 on snap ring 11, the second wirerope 10 positioned at middle part is close
8 side of pier shaft anchor ear separates two shorter third wirerope, mounts lifting point respectively.When being arranged in this way, need to guarantee pier shaft
Identical, uniform force is arranged in 8 two sides of anchor ear, can smoothly complete 8 two sides of pier shaft anchor ear while drop.
Step 6, branch dismantle the high-strength bolt on pier shaft anchor ear 8；Specifically: first, it is high to unclamp 8 middle part of pier shaft anchor ear
Strength bolt (not directly removes), then free end high-strength bolt, and alternately, the stress release to pier shaft anchor ear 8 finishes
Afterwards, high-strength bolt is removed；Second, the flange of pier shaft anchor ear 8 distinguishes the thick cork wedge 13 that inserting thickness is 70mm up and down, soft
Timber wedge 13 gos deep into template 20mm, and for expanding anchor ear spacing, convenient for falling, flange installs stay bolt, and bolt should be fastened suitably
Timber wedge 13 is clamped, is shaken during preventing anchor ear from dropping and timber wedge 13 is fallen.
Step 7, installation buffering cork；Ship type plank 12 is inserted into pier shaft anchor ear 8 and pier shaft gap；Wherein, plank 12
For thickness 20mm, length 500mm, width 200mm；Plank 12 is pine or cypress.Each two of every side, as under pier shaft anchor ear
Sliding rail when falling prevents anchor ear and pier shaft friction damage from polluting pier shaft.12 installation site of cork sheet is as shown in Fig. 6,7.
Step 8 removes the steel pipe column of support pier shaft anchor ear 8, tenses the first wirerope 9 connecting with hoist engine 7, makes steel
Tubing string and anchor ear are detached from, and steel pipe column is cut and disassembled in merogenesis；
Step 9 drops pier shaft anchor ear 8 by hoist engine 7, and ensure pier during dropping after steel pipe column is dismantled
The two sides of body anchor ear 8 are synchronous to fall, until anchor ear drops down onto ground, removes connection bolt, anchor ear is hoisted to storage point by truck-mounted crane；
Step 10 removes and recycles anchoring ring.
It is to be noted that the steel pipe column in step 8 is only to play a supporting role when starting to do pier shaft anchor ear 8
Structure.The steel pipe column can also be not provided with.
Anchoring ring provided by the utility model and pier shaft anchor ear drop system, and simple structure, material is common, easy to process,
The anchor ear that can be coped under various complicated environmental conditions is removed, while saving manpower and machine cost, is guaranteeing construction quality
Under the premise of improve construction efficiency.
The foregoing is merely the preferable specific embodiment of the utility model, but the protection scope of the utility model not office
Be limited to this, variation that anyone skilled in the art is expected within the technical scope disclosed by the utility model or
Replacement, should be covered within the scope of the utility model.
