The utility model patent provides a kind of prefabricated piling strtucture, includes the concrete pile body of specific hollow cavity, institute
The circular in cross-section of hollow cavity is stated, the upper end and lower end of the pile body are equipped with the end cap for closing the pile body
Plate, the outward flange of the end casing has the flanging extended to the pile body axial direction, and the lower surface of the end casing is provided with
The elastic projection being engaged with the hollow cavity, the lateral wall of the pile body is provided with modified asphalt layer and corrosion-resistant wired tube
Pipe, the outer surface of the end casing is coated with teflon coatings.
It is preferred that, the corrosion-resistant braided sleeving is formed using glass fibre and carbon fiber braiding.
It is preferred that, the material of the elastic projection is rubber.
It is preferred that, the material of the end casing is steel.
It is preferred that, the end casing is mechanical connection with the pile body.
The beneficial effect brought of technical scheme that the utility model is provided is：The utility model passes through up and down the two of pile body
End sets end casing, and coordinates elastic projection to be sealed hollow cavity, makes pile body generally in closed state, prevents salt marsh
Soil and bittern corrode pile body, and are set in the lateral wall of pile body outside modified asphalt layer and corrosion-resistant braided sleeving, end casing
Surface teflon coating, substantially increases decay resistance, impermeable, and durability is good, reliable in quality.
Brief description of the drawings
In order to illustrate more clearly of the technical scheme in the utility model patent, required in being described below to embodiment
The accompanying drawing used is briefly described, it should be apparent that, drawings in the following description are only some implementations of the present utility model
Example, for those of ordinary skill in the art, on the premise of not paying creative work, can also be obtained according to these accompanying drawings
Obtain other accompanying drawings.
Fig. 1 is the structural representation for the prefabricated piling strtucture that the utility model is provided.
[reference in figure]：
10. pile body, 20. end casings, 30. hollow cavities, 40. elastic projections, 50. modified asphalt layers, 60. is resistance to
Corrode braided sleeving.
Embodiment
To make content of the present utility model more clear understandable, below in conjunction with Figure of description, to of the present utility model interior
Appearance is described further.Certain the utility model is not limited to the specific embodiment, known to those skilled in the art
General replacement be also covered by protection domain of the present utility model.Secondly, the utility model has been carried out in detail using schematic diagram
Statement, when the utility model example is described in detail, for convenience of description, schematic diagram should not according to general ratio partial enlargement
Limited in this, as to of the present utility model.
Above and other technical characteristic and beneficial effect, will in conjunction with the embodiments and accompanying drawing is to static pressure pipe pile of the present utility model
It is described in detail.As illustrated, Fig. 1 is the structural representation for the prefabricated piling strtucture that the utility model is provided.
As shown in figure 1, the utility model provides a kind of prefabricated piling strtucture, include the concrete pile body of specific hollow cavity
10, the circular in cross-section of hollow cavity 30, the upper end and lower end of pile body 10 are equipped with the end casing 20 for closing pile body,
End casing 20 is mechanical connection with pile body 10.The outward flange of end casing 20 has the flanging extended to the axial direction of pile body 10, end
The lower surface of cover plate 20 is provided with the elastic projection 40 being engaged with hollow cavity 30, and the material of elastic projection 40 is rubber.Elasticity
Projection 40 is embedded in hollow cavity 30, can be prevented salinized soil and bittern from corroding pile body, be improved pile body sealing property.
To prevent pile body from being corroded, the lateral wall of pile body 10 is provided with modified asphalt layer 50 and corrosion-resistant braided sleeving
60, corrosion-resistant braided sleeving 60 is formed using glass fibre and carbon fiber braiding.
