Description
Technical field
The present invention relates to piling Technology field more particularly to mini piling Technology fields.
Background technology
Mini stake belongs to a kind of slip casting type miniature steel pipe pile.Mini pile driving construction is using mini stake drilling pile work method (Odex
Method) drill, soil layer or boulder layer are cut using beche and eccentric down-the-hole type drill hammer, it is synchronous permanent steel
Casing is crept into together to basement rock.The outer diameter of permanent steel sleeve is Φ 273, thickness 10mm, and material rank, which is that S275 is solderable, takes over.
After scarfing cinder for the first time and collection rock specimens, all drilling rods, beche and eccentric drill hammer (Odex) are extracted out and removed, then
It uses one group of beche instead and 250 down-the-hole type drill hammers (Down-The-Hole) of Φ carries out embedding petrosa part drilling operating, it is embedding
Rock diameter will not be less than Φ 250, until the socket length of design requirement is reached until, stake holes socket length be 4.1m, rock
Supporting course is III level rock or more preferably ragstone.6 φ 40 are placed after borehole cleaning, the steel reinforcement cage that rank is A400, it is synchronous to transfer
Grouting Pipe, and B50 non-shrinkage mud piles are perfused, the compression strength of 28 days is no less than 50MPa.Mini pile driving construction equipment
Small, flexibility is high, adapts to narrow and small construction area, has the characteristics that quick pile.
The construction method of ordinary pile foundation steel reinforcement cage has：(1) it is long according to stake, steel reinforcement cage is made section by section in steel bar meter field
It finishes, pile foundation construction scene is transported to by transport vehicle, is then lifted by crane section by section by loop wheel machine, docking and then decentralization are until all steel reinforcement cages
Segment decentralization finishes.Since mini pile cages main reinforcement spacing is smaller, the sleeve connection of steel reinforcement cage docking is relatively difficult, construction
Efficiency is low.(2) long according to stake, first main reinforcement, all docking is completed, and then binds into steel reinforcement cage again, and fabrication of reinforcing cage finishes, and is turned
Construction site is transported to, loop wheel machine is hung.Since part stake is grown in 60m or so, long steel reinforcement cage be subject to place due to being limited nothing
Method is transported and directly lifted by crane, therefore this method can not meet the decentralization of long steel reinforcement cage, therefore also undesirable.
The content of the invention
It is an object of the invention to solve ordinary pile foundation steel reinforcement cage installation method not being suitable under mini pile cages installation
The problem of putting, provide it is a kind of efficiently, adapt to that various stakes are long and the mini pile cages construction method of installation of place limitation.
To achieve these goals, present invention employs following technical schemes：A kind of mini pile cages installation method,
Suspender including loop wheel machine and for lifting by crane main reinforcement, is installed using following steps：
(1) according to the long definite reinforcing bar length of stake, several segment groups, every group of 6 reinforcing bars, every steel are divided into steel bar meter field

Prepare loop wheel machine and suspender, the suspender includes a hoisting board, and hoisting board center upper portion is provided with hanging hole, hoisting board lower part
3 lifting hole(eyelet)s are set, and each lifting hole(eyelet) is hung with a fixed pulley, and each fixed pulley is hung with a steel wire rope, and every steel wire rope both ends are equal
Connection hangs sleeve openings end to be tapped with internal thread there are one suspension sleeve；
(2) according to reinforcing bar matching order, loop wheel machine is sling above lifting appliance moving to bottom cage group reinforcing bar, and 6 on suspender are outstanding
Hanging sleeve cylinder is threadedly connected to the external screw thread of bottom cage group reinforcing bar, and after connection, loop wheel machine, which slowly hooks up, is lifted to bottom cage group reinforcing bar
Plumbness is moved to above mini stake holes；
(3) reinforcing bar is pulled up and down so that the 6 foundation cage group reinforcing bar bottoms sling are concordant, close to reinforcing bar bottom 20cm's
Position sets first separator, and respectively 6 reinforcing bars are nested together with a clip in first separator upper-lower position, beam
Integrated steel reinforcement cage, loop wheel machine slowly descend hook to enter steel reinforcement cage in mini stake holes, above first separator 1.6~2.2 meters away from
From position stop, second separator is set, similarly, in second separator upper-lower position respectively with a clip by 6 steel
Muscle is nested together, and loop wheel machine slowly descends hook, every 1.6~2.2 meters of distances repeat to set separator and clip constriction reinforcing bar and under
It hangs, until when one group of clip of bottom cage group reinforcing bar the top setting is close to mini stake holes aperture, loop wheel machine stops lower hook,
For the separator by being formed from the six roots of sensation spoke of the outside isogonism radiation extension in center, six roots of sensation spoke separates reinforcing bar
Different sector regions；
(4) rod iron that 2 root long degree are more than stake holes diameter is interted in the gaps underneath position of one group of the top clip, loop wheel machine is again
Secondary slowly lower hook until steel reinforcement cage by rod iron support on mini stake holes mouth, by the bottom cage group reinforcing bar in mini stake holes with it is outstanding
The dismounting separation of hanging sleeve cylinder；
(5) loop wheel machine plays lifting appliance moving to next group of reinforcing bar, and 6 suspension sleeves on suspender are threadedly connected to steel respectively
Muscle, after connection, loop wheel machine slowly hooks up reinforcing bar being lifted to plumbness, is moved to and has been installed in mini stake holes by loop wheel machine
Steel reinforcement cage above, with branch sleeve by the reinforcing bar sling be located at stake holes in reinforcing bar docked one by one by root, after connection,
Placing a separator again apart from the position of upper 1.6~2.2 meters of a separator, with clip by reinforcing bar be nested together constriction into
Steel reinforcement cage is slowly hooked up after being inserted in 2 rod irons of clip bottom with taking-up, then slowly lower hook, is stopped every 1.6~2.2 meters of distances
Hook is only descended, separator and clip are set, reinforcing bar is nested together constriction into steel reinforcement cage, often binds one section of steel reinforcement cage decentralization one
Section, until when one group of the top clip will be into stake holes, loop wheel machine stops lower hook；
(6) step (4), (5) are copied until the installation of whole pile steel reinforcement cage and lower section finish, then transfer it with similary step
His stake holes steel reinforcement cage.
The separator is welded by 20 reinforcing bars of Φ of 6 equal lengths according to M shape.
It is preferably to be separated by 2m to be often separated by 1.6~2.2 meters of distances in step (3) and step (5).
The loop wheel machine is 25t truck cranes.
Bottom cage group is made of 6 reinforcing bars that length does not wait, and the reinforcing bar group outside the cage group of bottom is made of the reinforcing bar of equal length.
The present invention has the special feature that, and to be steel reinforcement cage transfer when making, construction efficiency height, from the influence in place, while steel
Muscle cage decentralization verticality is high, and lifting method is flexible, easy, safe operation, and construction effect is notable.
