Abstract
The utility model discloses a prestressing concrete pipe pile. The prestressing concrete pipe pile comprises a concrete pile body, wherein a plurality of annular protrusions are arranged axially at intervals on the outer side of the concrete pile body, grooves are formed in the annular protrusions, and slope surfaces are arranged on two sides of the annular protrusions. Compared with existing pipe piles, the prestressing concrete pipe pile has the advantages of being large in friction force and high in pile sinking speed.
Description
Technical field
The utility model relates to pile tube, especially a kind of prestressed concrete pipe pile.
Background technology
At present, the output of pile tube constantly increases, but existing pile tube can't satisfy the demand in some special area.For example in the comparatively soft area of geology, the bearing capacity deficiency of stake, prior art can only improve bearing capacity by diameter or the length that increases pile tube, has increased cost and difficulty of construction, also causes the wasting of resources.
The utility model content
The utility model purpose: the utility model will provide a kind of frictional force bigger prestressed concrete pipe pile.
Technical scheme: a kind of prestressed concrete pipe pile of the present utility model, comprise the concrete pile body, the external side of described concrete pile arranges a plurality of annular protrusions vertically at interval, and described annular protrusion is provided with groove, and the both sides of described annular protrusion are provided with domatic.
One end of described concrete pile body fixedly has the stake point, along a plurality of stiffeners that are axially arranged with of described stake point.The other end of described concrete pile body is provided with terminal annular protrusion.Described domatic angle of inclination is 30 ~ 60 °.The length of described concrete pile body is 7 ~ 15 meters.The spacing of adjacent described annular protrusion is 1.5 ~ 2.5 meters.Described stake point is identical with the angle of inclination of stiffener, and is 15 ~ 60 °.The cross section of described groove is arc.
Beneficial effect: compare with the pile tube of same diameter and length, the utlity model has the big advantage of frictional force, can use in the softer area of geology.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, prestressed concrete pipe pile of the present utility model comprises concrete pile body 1, and concrete pile body 1 outside arranges at interval a plurality of annular protrusions 2 vertically, and it is domatic 3 that the both sides of annular protrusion 2 are provided with, and domatic 3 angle of inclination is 30 ~ 60 °.Annular protrusion 2 is provided with groove 4, and the cross section of groove 4 is arc.One end of concrete pile body 1 fixedly has stake point 5, and along a plurality of stiffeners 6 that are axially arranged with of described stake point, stake point 5 is identical with the angle of inclination of stiffener 6, and is 15 ~ 60 °.The other end of concrete pile body 1 is provided with terminal annular protrusion 7.The length of concrete pile body 1 is 7 ~ 15 meters, and the product length of different size differs 1 meter.The spacing of adjacent annular protrusion 2 is 1.5 ~ 2.5 meters.Since be provided with a plurality of annular protrusions and annular protrusion be provided with groove, both sides be provided with domatic, thereby the frictional force of pile tube has been increased a lot, and pile sinking speed and existing pile tube are approaching.
