Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Abolishing device has two kinds of structure types：
Filling pile head as shown in Fig. 1-3 abolishes device, including three coaxial annular casings 1.1, annular casing
Between 1.1 top an integrally-built device body 1 is fixedly connected as by being coupled strength plate 1.2.Device body 1 is outermost
Gap between annular casing annular casing adjacent thereto is cage bar locating clip layer 3, the outermost annular casing of device body 1
The distance between the inwall outer wall of annular casing adjacent thereto be less than the diameter of cage bar 6.
As shown in Fig. 4-6, including two coaxial annular casings 1.1, pass through device between the top of annular casing 1.1
Top plate 1.3 is fixedly connected as an integrally-built device body 1.The outermost annular casing of device body 1 ring adjacent thereto
Gap between shape casing is cage bar locating clip layer 3, and the middle part of device top plate 1.3 is provided with the through hole 11 of concrete perfusion.
The top of the device body 1 of two kinds of structures is respectively and fixedly provided with two and plays hanger relative to the axisymmetrical for abolishing device
The reinforcing bar of plate 4 and two axisymmetricals relative to device body 1 wears mouthful support 5, and reinforcing bar wears mouthful support 5 to be fixed on device sheet
The square set that the reinforcing bar at the top of body 1 is surrounded.The height of device body 1 is all higher than the hole that pile crown abolishes segment length and stake holes 7
Push up the length sum of cage bar 6.
When attachment means for connection strength plate 2 when, the inwall of the outermost annular casing of device body 1 annular adjacent thereto
The distance between outer wall of casing is slightly less than the diameter of cage bar 6, so that cage bar 6 positions in cage bar locating clip 3, can also pass through
Reinforcing bar is passed through in reinforcing bar wears mouthful support 5, device whereabouts is abolished in limitation, to ensure positioning of the cage bar in cage bar locating clip 3.
The construction method for abolishing device designed by the utility model comprises the following steps：
1), before stake holes drilling, decentralization final section steel reinforcement cage is completed, in the outermost annular casing of device body 1
Releasing agent is coated with the outer wall of inwall and annular casing adjacent thereto.Device body 1 is arranged and is fixed on final section steel
The top of muscle cage, by fiber band passed through after shackle plate 4 with the banding fixed of cage bar 6.
2), the final section steel reinforcement cage for being provided with device body 1 is put into stake holes 7, the spacer bar of steel reinforcement cage is worn
Cross reinforcing bar and wear mouthful support 5, and two of spacer bar is placed on the sleeper for be layed in ground and is fixed, filled into stake holes 7
Concrete is noted, forms pile foundation；At the end of concreting is fast, multiple suspension ring 2 are inserted on the top of pile crown concrete, such as Fig. 7
It is shown：Suspension ring 2 include two vertical dowels 2.1, and semi-circular shape ear muscle 2.2 is fixedly connected between the top of two dowels,
Bearing rod 9 is fixedly connected between multiple suspension ring 2.
3), after pile foundation concrete reaches initial setting strength, the spacer bar of steel reinforcement cage is removed, wears the steel wire rope of loop wheel machine
Cross shackle plate 4 and extracted device body 1 by loop wheel machine；
4), after pile foundation concrete reaches the intensity of code requirement, cushion cap foundation ditch is excavated, when cushion cap excavation of foundation pit is completed simultaneously
, can be by hand hammer, chock by outer and interior the concrete of pile crown section is peeled off and transported from level to level after excavating out pile crown section.Also can be first
Section is first abolished to pile crown using air drill and digs out ring groove, then throws several chocks into, and chock is entered by external force
Row taps, and pile crown is abolished into section concrete wedge breaks after the degree that can be pulled off to loop wheel machine, by wire rope rope on suspension ring, passes through loop wheel machine
Hoisting wirerope integrally hangs out the pile crown part for needing to cut after separation.
The utility model abolishes section concrete progress subregion to pile crown by abolishing device, is mixed reducing cage bar 6 with pile crown
Bond stress between solidifying soil, eliminate and pick while hindering 6 risk of cage bar that pile crownization is greatly small, realize pile crown block-by-block and abolish, reduce
To the performance requirement of lifting appliance, the construction efficiency and the scope of application of original pile crown breaking construction method are improved, reduce
Construction fugitive dust, reduce construction cost.With applied widely, constructing operation is easy, and speed of application is very fast, reliable construction quality
The advantages of.Meet the requirement of green construction, the large diameter pile foundation pile crown that is particularly suitable for use in abolishes construction.
It is described above, only it is preferred embodiment of the present utility model, not structure of the present utility model is done any
Formal limitation.Every any simple modification made according to the technical essence of the utility model to above example, it is equal
Change and modification, in the range of still falling within the technical solution of the utility model.
