To keep above-mentioned technical proposal clearer, Hanging Basket on the grand bridge 214#-217# continuous beams of Xiang Tan is described in detail below
Back off procedure.
Xiang Tan grand bridge 214#-217# continuous beams are 75+125+75m rotator construction continuous beams, are positioned at sweep
1200m, in the curve location of vector distance 26cm, and on the station tracks such as across Shanghai elder brother's railway, Hunan steel industrial siding 5, be across the railway station track in China
One of most swivel continuous beam, using Hanging Basket free cantilever casting, across closing up in finally turning.After closing up for general building site beam,
It can remove to unload in situ and hang, only Hanging Basket, which is return back to other than safe-guard line, on both wired could carry out dismounting work.It is existing
Discovery is checked in field, and Hanging Basket needs are retreated from 216# pier span centres position to from the segments 2#, after outside existing railway coverage, ability
It is removed, meanwhile, being limited by busy existing Shanghai elder brother transportation route influences, and not only traffic safety risk is high, but also can give
The construction time given is extremely limited, it is necessary to disposable in a short time to retract in place.
Hanging Basket is Diamond-Shape Form Traveler, and the square-section rod piece that diamond shape purlin piece is made of the common hot-rolled steel channels of 40b is constituted, front beam
It is made of I 56b I-steel, basket forward and backward crossbeam in bottom is made of I 40b I-steel, and sunpender pricks screw-thread steel using the essence of Φ 32.It hangs
Before basket retracts, structural strengthening is carried out first, and specifically, in both sides diamond shape purlin, under piece increases vertical supporting steel member and longitudinal direction
Hanging Basket stress system is converted into freely supported structure by cantilever design and examines calculation reinforcing Hanging Basket system, ensures entire Hanging Basket system by nose girder
The stabilization row moved after system.After closure segment pours completion demoulding, scene using chain block, sunpender etc. by side form and bed die system with
Diamond-Shape Form Traveler lower and upper cross-member, which is connected and fixed, forms an entirety.After Hanging Basket releases anchor system before retreating, the lotuses such as lower part template
It carries and is all transmitted on overhanging upper beam by screw-thread steel, inspection is needed to count whether the force-bearing situations such as portion's main couple, crossbeam meet in,
It cannot such as bear to need to take strengthening measure, (be referred to through entrusting outer detection unit inspection to calculate《Newly-built Chang Zhu Tan inter-city passenger rail synthesis III
It marks 216# pier Hanging Baskets and retreats dismounting inspection calculation report》), hanging basket main truss, upper front beam amount of deflection, intensity are satisfied by requirement, but it is upper after
Crossbeam only amount of deflection meets, and brace maximum stress is more than allowable stress value, is unsatisfactory for code requirement, it is proposed that increases water at brace
Flat chord member.Scene is imagined increases horizon bar in upper rear cross beam position, and horizon bar is spliced to form using 12, is adopted between rod piece and rod piece
With fillet weld full weld, weld bead height is not less than 8mm.After inspection calculates and increases horizon bar, rear cross beam maximum stress meets intensity and wants
It asks.
After being unclamped for anchor point after Hanging Basket, the problem of cradle structure torque is without safety stock, using increasing cradle structure branch
Point increases structural stability.In both sides diamond shape purlin, under piece increases vertical supporting steel member and longitudinal nose girder, and duplex is used between bilateral
Word steel is welded to connect, and is increased to reinforce between rod piece angle point and walking rails in every side and be connected with Double-layer two-splice I-steel, by Hanging Basket
Stress system is converted into freely supported structure by cantilever design, so that cradle structure torque is had safety stock during traveling, and be not required to
Anchor position increases the frictional force that counterweight increases suspended basket after giving Hanging Basket original, increases rod piece and only increases structural stability, is not necessarily to
Inspection is calculated.
It waits after the completion of reinforcing, Hanging Basket bottom basket and template system are fallen 2.95m at twice, and first time whereabouts 2.35m is exited
Both the segments 4# position falls 0.6m again after wired, is fixed side form and crossbeam using steel wire rope and chain block.216# pier span centres
Bottom elevation is 82.35m, and the segments 4#, the segments 4# lower section is in both wired outer, the segments bottom elevation 80.44m, 2# bottom elevation
79.86m.Hanging Basket bottom basket and bed die top surface absolute altitude are first dropped into 80.00m in span centre position before retracting, Hanging Basket is retreated to 4# and saved
Duan Shi, bed die and beam bottom headroom 0.44m, Hanging Basket bottom basket bottom absolute altitude is 79.18m at this time.K4 lines and Hunan steel industrial siding K5 carrier cables
Absolute altitude 77.101m, Hanging Basket bottom and carrier cable height difference 2.1m.Hanging Basket retreats to both wired outer rear (segments 4#) and again drops to bottom basket
Then 79.4m retreats Hanging Basket to the segments 2#, complete to retreat.
Adjustment fixed pulley spacing is determined using method in vector distance point, specifically, considers to be not provided with adjustment pulley, arrangement first
The case where rectilinear orbit, the Hanging Basket forward and backward crossbeam both sides that retract respectively have an essence to prick spiral shell mosquito steel as hanging basket bed die and side form
Supporting member, it is 15cm, walking rails circuit (i.e. Hanging Basket rollback circuit) at a distance from beam body flange plate that every essence, which pricks spiral shell mosquito steel,
The distance between Hanging Basket theory plan rollback circuit is vector distance.Hanging Basket arranges that rectilinear orbit retracts, Hanging Basket rollback circuit and extension
26cm vector distances are generated between basket theory plan rollback circuit, Hanging Basket side essence, which pricks spiral shell mosquito steel, will collide beam flange plate, and Hanging Basket has side
The security risk inclined, it is also possible to can not complete to retreat in limited construction skylight point, make Hanging Basket rest on both wired, to transport
Busy Shanghai elder brother line traffic safety makes a big impact.Therefore the curve element arrangement that track only presses beam is retreated, is to sum up analyzed, only
Arrangement adjustment fixed pulley can be considered, the case where design curve track out of shape.
Rail overall length is by many single straight rails, the similar curve track of composition.Method is for adjusting in vector distance point
The method of difference (claiming vector distance) between the whole practical rollback circuit of Hanging Basket and theoretical rollback circuit, makes Hanging Basket in back off procedure central sill
The offset distance of cross-sectional direction is less than the minimum safe distance 15cm between Hanging Basket and beam body flange plate；It is calculated through drawing, using fixed
When one per 10m dilatory steel hinge line of adjustment of pulley is linear, vector distance 10cm, using the every 5m of the fixed pulley together dilatory steel hinge line of adjustment
When linear, vector distance 2.5cm, it is contemplated that Hanging Basket cannot be more than 3cm in the upper deviation of practical back off procedure middle orbit, otherwise
Hanging Basket has the risk for deflecting away from rail, may cause security risk or need satisfactory after correcting is taken to delay to move back the Hanging Basket time, institute
It is adjusted together per 5m with method selection in vector distance point and draws the linear scheme of steel hinge line, the vector distance after adjustment is 2.5cm, is less than track
Traveling difference 3cm and flange plate safe distance 15cm ensures that the traveling of Hanging Basket rollback is safe and smooth.

Gross weight N=60t.Startup power：Steel friction coefficient μ takes 0.2, starts frictional force F=μ N=600 × 0.2=120KN；Sliding
Power：Steel friction coefficient μ takes 0.15, starts frictional force F=μ N=600 × 0.15=90KN.It is moved according to the above Hanging Basket that calculates
It moves minimum startup power and is more than 120KN, could the dilatory movement of Hanging Basket, Hanging Basket movement be set stretch-draw jack by two fulcrums and dragged
It draws, so it is 60KN that jack lowest pull is drawn in everywhere, jack selects ZLD20 type stretch-draw jacks, maximum stretching force
For 200KN, it can know that 2 ZLD20 types stretch-draw jacks can draw movable hanging basket from calculating, as a result of continuously tensioning
Method avoids the compartment for moving back anchor, oil return, upper anchor, and everywhere draws jack and connected by 2 jack, to what is realized
One tensioning, another is moved back anchor, oil return, upper anchor, toward the continual progress tensioning operation of complex Alternating.From the safety stock for moving back Hanging Basket
Consider, Hanging Basket anchor point is drawn in everywhere, increases by one of steel strand wires and Hanging Basket is drawn in 2 jack series connection, Hanging Basket is made to retract
Process is safer, and in practice, Hanging Basket, which retracts, draws jack everywhere by 4 ZLD20 type stretch-draw jack combination of two
It forms, point is drawn at two and configures 8 ZLD20 type stretch-draw jacks altogether.
After jack arranges, it is fixedly mounted by counter-force seat, counter-force seat basis utilizes anchor embedded hole after 0# block original Hanging Baskets,
Steel locking steel plate is pricked using essence to be formed, and then welds counter-force seat on the steel plate.Finally install traction steel strand wires and jack etc.
Pulling equipment.It is drawn using jack and dismantles Hanging Basket after Hanging Basket retracts to home.
