Abstract
The utility model discloses a concrete pipe pile, which comprises a main body, wherein the main body comprises a steel pipe layer and a concrete layer positioned inside the steel pipe layer; a central hole is formed in the middle of the concrete layer and penetrates through the upper end and the lower end of the concrete layer; two or more steel sleeve pipes penetrate through the main body and horizontally penetrate through the two sides of the main body; the axis lines of the sleeve pipes intersect on the axis line of the central hole; the two adjacent sleeve pipes are perpendicular to each other; meanwhile, the outer diameter of the sleeve pipes is smaller than the inner diameter of the central hole; a cone-shaped expanding end with a bottom big end is formed at the lower part of the main body in a cast-in-place manner. The concrete pipe pile has the benefit of preferable shock resistance.
Description
Technical field
The present invention relates to concrete products technical field, especially relate to a kind of concrete tubular pile.
Background technology
Concrete tubular pile is mainly used in the infrastructure of high-rise building, railway bridge engineering.A kind of concrete tubular pile wherein comprises steel pipe layer and is positioned at the layer of concrete of this steel pipe layer inside, and this layer of concrete middle part has the centre bore that connects this layer of concrete upper and lower side., this layer of concrete adopts centrifugation moulding.Its defect is: in softer medium, especially have in the medium of drift sand, the impact resistance of this concrete tubular pile is poor.
Summary of the invention
The object of this invention is to provide a kind of concrete tubular pile, it has the feature of good impact resistance.
The technical solution adopted in the present invention is: concrete tubular pile, comprise body, this body comprises steel pipe layer and is positioned at the layer of concrete of this steel pipe layer inside, and this layer of concrete middle part has the centre bore that connects this layer of concrete upper and lower side, on described body, be penetrated with at least two steel sleeve pipes, the both sides of what this sleeve pipe was horizontal run through this body, the axial line of this sleeve pipe intersects at the axial line of this centre bore, and two adjacent sleeve pipes are mutually vertical, simultaneously, the external diameter of this sleeve pipe is less than the internal diameter of this centre bore, and, the bottom of this body by cast-in-place mode form large end under taper shape expand termination.
The advantage that the present invention has is: have good impact resistance.The sleeve pipe that concrete tubular pile of the present invention has makes the media such as drift sand can be full of the inner chamber of this sleeve pipe and can circulate in the inner chamber of this sleeve pipe, thereby reduced medium, pile tube is impacted.Meanwhile, the expansion termination of the larger volume that this pile tube has, makes this pile tube comparatively stable, has then further strengthened the impact resistance of this pile tube.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is that the master of embodiments of the invention looks sectional view.
In figure: 10, body, 11, steel pipe layer, 12, layer of concrete, 121, centre bore; 20, sleeve pipe; 30, expand termination.
Detailed description of the invention
Embodiment, as shown in Figure 1: concrete tubular pile, comprises body 10.This body 10 comprises steel pipe layer 11 and is positioned at the layer of concrete 12 of these steel pipe layer 11 inside, and these layer of concrete 12 middle parts have the centre bore 121 that connects these layer of concrete 12 upper and lower sides., this layer of concrete 12 is formed in the inner chamber of this steel pipe layer 11 in advance by centrifugal mode.Further say, on this body 10, be penetrated with at least two steel sleeve pipes 20.The both sides of running through this body 10 that this sleeve pipe 20 is horizontal, and the axial line of this sleeve pipe 20 intersects at the axial line of this centre bore 121.This sleeve pipe 20 can be fixed on this steel pipe layer 11 by the mode of welding.And two sleeve pipes 20 adjacent on above-below direction are mutually vertical.Like this, all directions flow compared with soft-medium such as the impact that drift sand causes this pile tube is less.Meanwhile, the external diameter of this sleeve pipe 20 is less than the internal diameter of this centre bore 121.And, the bottom of this body 10 by cast-in-place mode form large end under taper shape expand termination 30.This expansion termination 30 can adopt after 10 piling of this body put in place, adopt high-pressure rotary jetting apparatus rotation expand the below of stake bottom and use high-pressure rotary-spray pipe to stretch into this centre bore 121 by this centre bore 121, and by these centre bore 121 injected water mud, and cement paste can form cast-in-place expansion termination 30 after condensing.Like this, make this pile tube more stable by increasing the bottom area of this pile tube, its impact resistance is had been further upgraded.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes manual of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
