Detailed description of the invention
The embodiment of filling pile construction device described in the utility model is described below with reference to the accompanying drawings.This area general
Lead to and one of skill will recognize that, in the case of without departing from spirit and scope of the present utility model, can be with various different
Described embodiment is modified by mode or a combination thereof.Therefore, accompanying drawing and describe inherently the most illustrative rather than
For limiting scope of the claims.Additionally, in this manual, accompanying drawing draws not in scale, and identical accompanying drawing
Labelling represents identical part.
Provide a kind of filling pile construction device in the present embodiment, filling pile construction device as shown in Figure 1, including by
The conduit string that more piece sheathed catheter is connected together；Wherein, conduit is the hollow pipe column structure of rigidity；Inside N joint conduit upper end
Having upper back-up ring, wherein, on this, back-up ring 101 is connected with N joint conduit, and on this, internal diameter of back-up ring 101 saves conduit less than N
Internal diameter, on this internal diameter of back-up ring 101 be socketed on N joint conduit in N-1 joint conduit external diameter identical；This N joint is led
Pipe lower end outside has lower back-up ring 103, and wherein, this lower back-up ring 103 is connected with N joint conduit, and the external diameter of this lower back-up ring 103
The internal diameter phase of conduit is saved more than the external diameter of N joint conduit, the external diameter of this lower back-up ring 103 and the N+1 being socketed in outside N joint conduit
With；The external diameter of N+1 joint conduit is more than the external diameter of N joint conduit, under upper the back-up ring 101 and N-1 joint conduit of N joint conduit
Back-up ring 103 snapping, upper back-up ring 101 set of N joint conduit is pressed in the top of the lower back-up ring 103 of N-1 joint conduit；Wherein, N is big
In the natural number of 1.
By above-mentioned filling pile construction device, use rigid conduit, it is possible to reduce tubing string radial-play in construction and
Bending.Use N joint conduit upper back-up ring 101 and N-1 joint conduit lower back-up ring 103 snapping form by N joint conduit and
N-1 joint conduit socket, is connected into conduit string by more piece sheathed catheter successively, can either reduce the connection conduit time, can shorten again
The time extracted by conduit, enables concrete to pour into a mould continuously, and then effectively reduces pile breaking phenomenon.
In one alternate embodiment, the upper back-up ring 101 and M-1 of M joint conduit saves lower back-up ring 103 snapping of conduit
Position is provided with sealing packing ring 102, and wherein, M is the natural number less than or equal to N.Mud can be stoped to enter in conduit,
It is also possible to prevent concrete and oozes out conduit.
In one alternate embodiment, the outer circumference surface of the lower back-up ring 103 often saving conduit in conduit string has groove,
Groove is used for mounting gasket 102, prevents packing ring 102 play.
In one alternate embodiment, after forming conduit string, the lower back-up ring 103 of next the joint conduit in this conduit string
Inner side connects multiple prominent blocks, and this block is prominent to the inner side of next joint conduit, and the axle center of conduit string is to this block
The distance of the end of ledge is less than the external diameter of the lower back-up ring 103 going up most a joint conduit.Make to lead at lifting bottom N joint
Guan Shi, when N joint conduit block touch N-1 joint conduit lower back-up ring after, N joint conduit drive N-1 joint conduit to
Upper movement, thus, next joint conduit can utilize this block that each joint conduit is risen to the position in bored concrete pile aperture.
In one alternate embodiment, be uniformly fixed with outside the upper back-up ring 101 of next the joint conduit in conduit string many
Individual suspension member, this suspension member is for suspention next joint conduit.Utilize this suspension member, can by next joint conduit upwards
Lifting.
As in figure 2 it is shown, filling pile construction device includes the conduit string being socketed to form by more piece conduit 3.In this conduit string
Often joint conduit 3 is suspended on operating platform 2 by suspension apparatus 1.
The profile of filling pile construction device as shown in Figure 3, this filling pile construction device has included 2～3 or many just
Property conduit is formed by connecting, and number consecutively from top to bottom is mutually socketed between conduit.Have straight less than conduit inside each end of conduit
The back-up ring in footpath, lateral tail has the back-up ring more than conduit diameter.The diameter of conduit becomes larger from top to bottom, above the tail of conduit
Portion's back-up ring external diameter is consistent with following catheter diameter, above conduit diameter be consistent with following end of conduit back-up ring internal diameter.Conduit according to
Diameter is descending to be socketed successively, above catheter tail and following end of conduit set due to the mutual buckle of back-up ring, card buckle
There is back-up ring.After conduit socket, inside the lower back-up ring of next joint conduit, connect multiple block, the upper back-up ring of next joint conduit
Outside is uniformly fixed with multiple link.
In sum, by filling pile construction device of the present utility model, it is achieved that techniques below effect:
1., relative to lifting, dismantle the complicated procedures of forming of conduit in the bored pile construction in correlation technique, this practicality is new
Type need not conduit is promoted to ground every time and removes in whole casting process, it is possible to shortens conduit and extracts the time, makes to mix
Solidifying soil reaches to pour into a mould continuously, can effectively reduce broken pile and occur.Solve the cast-in-situ bored pile in correlation technique at cast concrete
During easily occur remedial measure cost after broken pile, and broken pile high, the problems such as stake of even giving up.
Conduit non-threaded the most of the present utility model connects, and coupling part is hardly damaged, and can change sealing ring as required.
Guide-tube structure the most of the present utility model is simple, installs, dismantles and constructs and be the most quick.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for this area
Technical staff for, this utility model can have various modifications and variations.It is all within spirit of the present utility model and principle,
