General thought
When pile foundation steel bar cage is processed, installation reinforcing bar and concrete isolating device on steel reinforcement cage top, in the superfilled part 2 of pile crown Position between live part 1 sets pre-buried HDPE plastic bellows.Treat that concreting completion, excavation of foundation pit are completed, tool During standby broken pile condition, pass through the pre-buried HDPE plastic bellows of steel wire penetrating.Steel bracket 6 is processed simultaneously, utilizes the top of steel bracket 6 Jack 7 is installed, pile crown inactive portion is integrally extracted.
Technical scheme
Such as Fig. 1 and Fig. 2, the device that pile crown abolishes efficiency is improved, sets steel reinforcement cage 4 in pile crown, such as Fig. 3 and Fig. 4, its bottom is Live part 1, top are superfilled part 2, and the interface of live part 1 and superfilled part 2 is truncation surface, including pre-buried isolation group Part and lifting component, pre-buried barrier assembly include one group of HDPE plastic bellows 3 being arranged horizontally on truncation surface in plane, And it is wrapped in the hydrophobicity heat preservation rock 11 in the steel reinforcement cage 4 of live part 1 in pile foundation cage bar 10 and sound detecting pipe;Lift by crane component Jack 7 including the steel bracket 6 installed centered on pile crown to be abolished and on steel bracket 6, such as Fig. 5, steel bracket 6 wraps The horizontal rectangular frame for include column 6.1, being fixed at the top of column and the crossbeam 6.2 being fixed among horizontal rectangular frame;Crossbeam 6.2 are provided with steel wire rope alignment pin 6.4, and jack 7 is carried out by the steel wire rope 1 through steel wire rope alignment pin 6.4 with steel bracket 6 Connection, while jack 7 is exerted a force by the superfilled part 2 of 29 pairs of steel wire rope through HDPE plastic bellows 3.
After pile foundation steel bar cage machines, certain limit in the every pile base cage bar 10 and sound detecting pipe at the top of steel reinforcement cage Interior parcel layer of hydrophobic heat preservation rock 11, ensure the parcel scope of hydrophobicity heat preservation rock 11 in casting concrete in future at In superfilled part 2 and the binding site of live part 1.Insulation hydrophobicity heat preservation rock 11 and pile foundation cage bar 10, sound detecting pipe pass through glue Band is fixed.Binding site upward 5~15cm, preferably 10cm simultaneously in the superfilled part 2 and live part 1 of concrete is pre- It is bigger 10cm than Pile Diameter to bury 4 Φ laterally to arrange 50mmHDPE plastic film capicitors, 3,4 tube lengths, horizontal direction is around mixed Native tumbling barrel 5 is coagulated to arrange into intersecting parallels.The pipe both ends of HDPE plastic bellows 3 are closed using adhesive tape, prevent from entering impurity.Ripple Pipe transfers installation with steel reinforcement cage.Embodiment pile foundation diameter calculates according to 2m, if diameter change, steel bracket size can phase It should adjust.
At the same time, a set of steel bracket 6 is processed in reinforcement yard, is made using 20# I-steel, between each component To be welded to connect;The altitude range of column 6.1 is 3.5m, and steel bracket, the branch of steel bracket bottom 4 are welded into using 20# I-steel Leg installs 4 sets of telescopic universal wheels 6.5.After machining, job site is transported to.Wherein, as Fig. 6,7, the bottom of column 6.1 are set There is the connecting pin bores 6.7 of two different heights above and below at least, respectively upper pin-and-hole and lower pin-and-hole;Latch 6.6 by lower pin-and-hole with When universal wheel 6.5 connects, steel bracket locomotive function is realized away from ground in the bottom of universal wheel 6.5 contact ground, the bottom of column 6.1, Such as Fig. 6;When latch 6.6 is connected by upper pin-and-hole with universal wheel 6.5, the bottom of universal wheel 6.5 connects away from ground, the bottom of column 6.1 Tread surface, realize steel bracket fixing function, such as Fig. 7.
After the completion for the treatment of that pile foundation concreting completion, excavation of foundation pit are completed, cushion cap blinding concrete pours.By steel bracket 6 In decentralization to foundation ditch.
Before pile foundation promoting or transferring, first with manually the dregs around pile foundation is cleaned out, pile foundation concrete is exposed, looked for simultaneously To pre-buried HDPE plastic bellows 3, the adhesive tape of pipe is released.Using abrasive wheel cutting machine in HDPE plastic corrugated conduit position Along the circle of pile crown cutting one, depth is pile foundation thickness of protection tier.This ensure that the integrity degree of bottom pile foundation concrete is not It is destroyed.
Steel bracket 6 is pushed into treat at promoting or transferring pile crown, universal wheel 6.5 is locked, column 6.1 is supported in the concrete of bottom Bedding plane, universal wheel 6.5 do not stress now.HDPE plastic bellows 3 is passed through using steel wire rope 29.Set on the top of steel bracket 6 Crossbeam 6.2, there is steel wire rope alignment pin 6.4 on crossbeam 6.2, steel wire rope 1 passes through steel wire rope alignment pin 6.4.Two parts steel wire rope Drawknot is carried out using 10t jacks 7.After everything is ready, jack is tensed step by step using the slide fastener of jack 7, passes through the power of jack 7 Amount makes pile crown integrally extract.Then recover universal wheel 6.5, the pile crown of extraction is transported to foundation ditch specified location using steel bracket.Treat After pile crown in whole foundation ditch is all extracted, integrally transported using transporting equipment.
When pile foundation steel bar cage is processed, on steel reinforcement cage top, installation reinforcing bar and concrete isolating device, invalid with having in pile crown Position HDPE plastic bellows 3 between effect.Treat that concreting completion, excavation of foundation pit are completed, when possessing broken pile condition, pass through Steel wire penetrating HDPE plastic bellows 3.Steel bracket is processed simultaneously, jack is installed using steel bracket top, pile crown is integrally pulled out Go out.
In construction, key technology point has:(1)Seepage does not occur for HDPE plastic bellows 3, ensures HDPE plastic bellows 3 It is unimpeded;(2)Ensure not permeable slurry between insulation hydrophobicity heat preservation rock and reinforcing bar, while do not fasten excessively again;(3)Ensure steel bracket Welding quality.
Calculating on cord strength:
Conventional steel wires rope is divided into two kinds of fibre core and steel core, tensile strength 1470MPa.Choose diameter 20mm steel wire ropes pair The steel wire rope minimum breaking force answered is 173KN and 187KN.17.3t and 18.7t are corresponded to respectively.This is the drawing of single wire rope Power, this technology use for 4, pulling force can reach 69.2t and 74.8t.Intensity can much meet to use needs.
It is used for wearing 4 steel wire ropes, the steel wire rope alignment pin at the top of steel bracket 6 in the HDPE plastic bellows 3 of pile foundation bottom 1 steel wire rope is worn in hole, the steel wire rope 1 on top and the steel wire rope 29 of bottom are connected by 10t jacks 7.Utilize jack 7 Pulling force breaks pile foundation, transports.
Steel wire rope 1 or steel wire rope 29 are when through steel wire rope alignment pin 6.4 or HDPE plastic bellows 3, in contact site Flexible material of jumping a queue is divided to protect steel wire rope not to be cut.
The utility model abolishes the device of efficiency using pile crown is improved, and improves speed of application, ensure that construction quality, protects Operation safety is hindered.Obtain owner's favorable comment consistent with operator's.
Preferred embodiment of the present utility model is these are only, it is all in the utility model not to limit the utility model Spirit and principle within, any modification, equivalent substitution and improvements made etc., should be included in protection model of the present utility model Within enclosing.
