As shown in Fig. 2 in one embodiment of the invention, the construction method of the steel reinforcement cage of super-large diameter engineering pile can be with
Comprise the steps：
Step 10, respectively places four piece positioning girder steels 50 in mode facing each other in the aperture 10 of engineering pile, each to position
Vertical dimension between girder steel 50 is corresponding with the diameter of the vertical muscle 20 of ground floor to be built, and suspend two in midair positioning per root on girder steel 50
The spacer bar 51 of the through bottom hole of root.
As shown in figure 3, in this step, four positioning girder steels 50 can be interfixed by the connection reinforcing bar 52 of 25mm,
To avoid positioning the stress movement in work progress of girder steel 50.
Four positioning girder steel 50 therein adopts 20a I-steel, elongated steel of eight spacer bars 51 using diameter 18mm
Muscle.As shown in fig. 6, the suspension of the spacer bar 51 can be in the following way：One is made using the reinforcing bar of 18mm and is enclosed within work
U-shaped hook 53 on word steel, then each spacer bar 51 is welded with corresponding U-shaped hook 53 respectively, 53 convenience are linked up with using U-shaped
The suspension point of adjustment spacer bar 51, makes positioning more accurate.
As shown in fig. 7, in other embodiments, it would however also be possible to employ three positioning girder steels 50 build Fa Laian using triangle
Dress spacer bar 51.
Step 20, places the outer layer positioning stirrup 21 that closing is circularized into hole by hoist cable, and outer layer is positioned stirrup
21 by predetermined longitudinally spaced distance respectively together with 51 colligation of each spacer bar.
In this step, hanging for stirrup 21 of outer layer positioning can be uniformly selected on outer layer spacer ferrule muscle 21 using rope
Four points are selected, by manually controlling progressively to be put in hole.
Step 30, positions 21 colligation of stirrup with each outer layer respectively to the self-indulgent muscle of hole infantile tic and by precalculated position, forms first
The vertical muscle of layer 20.
Vertical muscle in the step is hung and can be hung in hole by crane one by one, then is adjusted to installation position by root by hoist engine
Put.When colligation outer layer positions stirrup 21, first the outer layer positioning stirrup 21 at three positions in vertical muscle and upper, middle and lower can be tied up
Tie, with the current location of each vertical muscle of fixation, then tie up remaining outer layer positioning stirrup 21.
Step 40, hoop 22 of putting more energy into outside colligation on the vertical muscle 20 of ground floor, so far completes the colligation of the vertical muscle 20 of ground floor.
Step 50, adjusts the position of spacer bar 51 on each positioning girder steel 50, then complete by the order of step 20 to step 40
Into the colligation of the vertical muscle 30 of the second layer, the positioning girder steel 50 in aperture 10 is then removed.
As shown in figure 4, in the step, when the position of spacer bar 51 is adjusted, each positioning girder steel 50 can be remained stationary as
And the spacing distance increase between two spacer bars 51 on girder steel 50 only will be positioned per root or is reduced, the mode of adjustment can be with
It is the both sides or middle part movement U-shaped hook 53 to I-steel.
Step 60, determines the central point of the vertical muscle 40 of inner ring, and it is reserved to build band in aperture 10 by the diameter of the vertical muscle 40 of inner ring
Mouthfuls 61 operating platform 60, reserved opening 61 corresponding position fixed vertical in the spacer bar 51 of bottom hole.
As shown in figure 5, in the step, operating platform 60 needs to cover aperture 10 to facilitate workman to walk, the operation is put down
The concrete structure of platform 60 can adopt the I-steel of 20a to build main body frame, and each I-steel is welded to connect in main body frame
Pole reinforcing bar 54, and the upper surface in main body frame can cover template 55.The reserved opening 61 is shaped as square, the positioning
Reinforcing bar 51 has four and is separately positioned on the center on every side, and the fixation of spacer bar can adopt the suspention side in step 10
Formula.
Step 70, hangs inner ring reinforcing bar fixing muscle 42 into hole and fixes at predetermined intervals, to position the vertical muscle 40 of inner ring.
In the step, the longitudinally spaced distance of inner ring reinforcing bar fixing muscle 42 can be 2M, and the vertical muscle 40 of inner ring is improved with this
Stability, while in inner ring reinforcing bar fixing muscle 42 each reinforcing bar two ends need hold out against with the retaining wall in hole.
Step 80, hang into hole inner ring welding hoop 41 and at regular intervals with 51 colligation of spacer bar.
Step 90, binds round 41 colligations to the self-indulgent muscle of hole infantile tic and at predetermined intervals with inner ring welding, so far forms the vertical muscle of inner ring
40。
Step 100, packs up operating platform 60, completes the steel reinforcement cage colligation construction of whole super-large diameter engineering pile.
In the present embodiment, when the curtailment of vertical muscle, many bar dowels can be attached by sleeve, but together
On one horizontal plane, the area of steel for being cased with splice is difficult more than the whole area of steel on the horizontal plane 50%.
So far, although those skilled in the art will appreciate that detailed herein illustrate and describe multiple showing for the present invention
Example property embodiment, but, without departing from the spirit and scope of the present invention, still can be direct according to present disclosure
It is determined that or deriving many other variations or modifications for meeting the principle of the invention.Therefore, the scope of the present invention is understood that and recognizes
