Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with embodiment, it is clear that described
Embodiment be only the utility model a part of the embodiment, instead of all the embodiments.Based on the reality in the utility model
Example is applied, all other embodiment obtained by those of ordinary skill in the art without making creative efforts all belongs to
In the range of the utility model protection.
It please refers to shown in Fig. 1-3, a kind of prestressed-concrete pile point, including connector 1, sharp body 2 and pointed drill 3,1 bottom of connector
Portion is connected with sharp body 2, and sharp 2 bottom of body is connected with pointed drill 3, and tubular pole 7 is connected at the top of connector 1, is provided on sharp 2 side wall of body several
A equally distributed preformed hole 4 is provided with a sword slot 8 above each preformed hole 4, sharp sword 5 is equipped with inside sword slot 8, point
5 bottom end of sword is equipped with shaft 12, and interface channel 11 is respectively provided with inside each sword slot 8, and several auxiliary steel are connected at the top of connector 1
Muscle 6, auxiliary bar 6, which is worn, to be connected to inside tubular pole 7, and 6 side of auxiliary bar is provided with steel wire 9, steel wire 9 be located at 7 inside of tubular pole and
It is connected to inside connector 1,9 bottom end of steel wire is connected with the auxiliary strengthening tendons 10 being located inside sharp body 2, and auxiliary 10 bottom end of strengthening tendons imports pointed drill 3
It is internal.
Sharp body 2 and pointed drill 3 are pyramidal structure, so that pile top is more easier to penetrate sand when cooperating tubular pole to be driven piles
Layer.
The specification of sharp sword 5 is adapted with sword slot 8, and sharp sword 5 is between 8 inner wall of shaft 12 and sword slot by being movably connected,
Enabling sharp sword 5 in pile top, sharp sword 5 is incorporated in inside sword slot 8 when not in use, to effectively avoid the sharp leakage of sword 5 bring
Security risk.
Preformed hole 4 is in the ellipsoidal structure of indent, and is connected between sword slot 8 and preformed hole 4 by interface channel 11, is made
The sandy soil entered inside preformed hole 4 are obtained from interface channel 11 is squeezed into squeeze out sharp sword 5 inside sword slot 8, sharp sword 5 is extruded
Its sword plays the role of that pile top is assisted to penetrate sand bed afterwards, so that it is lighter to penetrate sand bed when piling.
Pile top is connected by auxiliary bar 6 and steel wire 9 with tubular pole 7, and connector 1 and pointed drill 3 are connected to by auxiliary strengthening tendons 10
Sharp 2 both ends of body, so that the connection between tubular pole 7 and pile top is more firm, and the integral strength of pile top is more preferably.
