Description
Technical field
The utility model is related to building field, more particularly to a kind of grouting behind shaft or drift lining Prefabricated hollow pile.
Background technology
Pile foundation is a kind of wide variety of deep foundation form, be mainly used in deep soft soil, soil property it is uneven and
Exist and built on the place of oscillatory load various build（Structure）The occasion of thing is built, construction skyscraper, heavy_weight factory is particularly applicable in
With the occasion of the building with particular/special requirement.Pile foundation is broadly divided into reinforced concrete pile and steel-pipe pile, at present using more
For reinforced concrete pile, reinforced concrete pile is broadly divided into bored concrete pile and prefabricated pile.
In recent years, prefabricated pile has the trend increased in some regional uses, and main cause is that prefabricated pile has quality steady
The advantages of fixed reliability, relatively low cost, short time limit, simple construction technology.Comparatively speaking, construction process of bored concrete pile is complicated, and easily hair
Make trouble former, reliability is not so good as prefabricated pile.Prefabricated pile is broadly divided into solid pile and hollow pile by its cross sectional shape.Because report is surveyed on ground
Simply indirect selects hole, it is impossible to show the whole circumstances of the soil body, therefore to improve the bearing capacity of pile body, using precast hollow
Stake pile-end post-grouting method is a selection well.
Conventional prefabricated pile post-grouting method mainly has following several at present：
（1）Perforate in pile top, after stake is sink to precalculated position, insertion Grouting Pipe carries out slip casting；
（2）Pile top is not set, after stake is sink to precalculated position, insertion Grouting Pipe carries out slip casting.
The deficiency of existing method：（1）Perforate in pile top, easily blocks injected hole, causes slip casting to fail；（2）If prefabricated sky
Heart stake is not provided with pile top, then in pile driving process, and the soil body can enter stake chamber, leads to not insertion Grouting Pipe and carries out slip casting.
Utility model content
The utility model can protect injected hole mainly solving the technical problems that provide a kind of grouting behind shaft or drift lining Prefabricated hollow pile
It is not blocked, it is ensured that Grouting Pipe is reliably connected.
In order to solve the above technical problems, the technical scheme that the utility model is used is：There is provided a kind of grouting behind shaft or drift lining prefabricated
Hollow pile, including：Prefabricated pile, end plate and pile top, the end plate are arranged at the bottom of prefabricated pile, and the pile top is arranged at end plate
Downside, cavity is offered inside the prefabricated pile, inserted with Grouting Pipe in cavity, in the prefabricated pile bottom, end plate
Upside uniformly offers some injected holes, and the injected hole is connected to Grouting Pipe, and one layer is coated with the outside of the injected hole
Rubber sleeve.
It is preferred that, the bottom of the cavity is set to turbination.
It is preferred that, a facing is provided with below the cavity bottom turbination.
It is preferred that, the bottom of the Grouting Pipe is set to external screw thread, and the external screw thread and silk facing phase of slip casting bottom of the tube
Match somebody with somebody.
It is preferred that, the injected hole with diameter greater than 10mm.
It is preferred that, the diameter of the silk facing is set to 30 ~ 60mm.
The beneficial effects of the utility model are：The utility model 1, one layer of rubber sleeve is arranged on the outside of injected hole so that
Injected hole is not easily blocked, reliable in quality；2nd, cavity bottom is arranged to turbination, for placing silk facing, reliable fixed silk tooth
Position is covered, and is connected using silk facing and slip casting bottom of the tube, connection is reliable, slip casting process stabilization.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the preferred embodiment of grouting behind shaft or drift lining Prefabricated hollow pile one of the utility model；
Fig. 2 is shown Fig. 1 sectional view；
Fig. 3 is shown Fig. 1 top view；
The mark of each part is as follows in accompanying drawing：1st, prefabricated pile, 2, pile top, 3, end plate, 4, cavity, 5, Grouting Pipe, 6, silk tooth
Set, 7, injected hole, 8, rubber sleeve.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model
It can be easier to be readily appreciated by one skilled in the art with feature, so as to make protection domain of the present utility model apparent clear and definite
Define.
Fig. 1 to Fig. 3 is referred to, the utility model embodiment includes：
A kind of grouting behind shaft or drift lining Prefabricated hollow pile, including：Prefabricated pile 1, end plate 3 and pile top 2, the end plate 3 are arranged at prefabricated pile 1
Bottom, the pile top 2 is arranged at the downside of end plate 3, cavity 4 is offered inside the prefabricated pile 1, in the interpolation of cavity 4
Enter to have Grouting Pipe 5, uniformly offer some injected holes 7 in the bottom of prefabricated pile 1, the upside of end plate 3, the injected hole 7 is connected
To Grouting Pipe 5, one layer of rubber sleeve 8 is coated with the outside of the injected hole 7.
In order to ensure to be not plugged up in injected hole 7 in piling, rubber sleeve 8 uses totally enclosed structure, is driving piles
Cheng Hou, using giant toward water filling in injected hole 7, the rubber sleeve 8 at injected hole is punctured by hydraulic pressure.
In order to ensure stability during slip casting, the bottom of the cavity 4 is set to turbination, and the bottom of the cavity 4
It is provided with a facing 6 below portion's turbination, the bottom of the Grouting Pipe 5 is set to external screw thread, and the bottom of Grouting Pipe 5
External screw thread matches with silk facing 6, during installation, by Grouting Pipe 5 and the rotation matching of silk facing 6 so that will not be let out during slip casting
Leakage, improves the stability of slip casting.
Further, the diameter of the injected hole 7 is set to 10mm, and the quantity of injected hole 7 is set to 3, the silk tooth
The diameter of set 6 is set to 30mm, and the diameter of injected hole 7 is less than the diameter of silk facing 6 so that have enough pressure in injected hole 7.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical fields, are similarly included in scope of patent protection of the present utility model.
