A kind of the CFG for easily blocking, including pile body, it is characterised in that：Expanded bore is offered on the pile crown side wall of pile body, is expanded
It is provided with making expansion bore expansion in hole so that the expanding part that is broken by the expansion of the expanded bore of the pile crown of pile body.
In the utility model, pile body is embedded in ground, when needing to block pile crown, using expanding part
Expanded bore is expanded, pile crown is broken when bore expansion is expanded, and then reach the purpose for cutting stake.The letter of its structure
Single, easy to use, pile crown does not cause to damage after blocking to pile body.
Used as optimization, the length of the expanded bore is the half of the pile body radius, and the expanding part is wedge I,
More than the area of section in the expanded bore aperture, the small bore end of wedge I is inserted in the expansion to the maximum cross-section area of wedge I
Open in hole, heavy in section end is stretched out in outside the pile body, the length that the wedge I is inserted into the expanded bore is less than the expansion
Open the length in hole.Wedge is usually stuck in expanded bore, bears a part of load, it is to avoid reduce self-strength because of expanded bore.
When stake is cut, part of the wedge I outside pile body is beaten by along expanded bore length direction, make wedge I towards expansion
Open the movement of hole bottom hole.During wedge I is moved, the lozenges of wedge II is connected to the aperture upper end of expanded bore, root
According to effect force resolution, wedge I acts on expanded bore aperture obliquely to the extruding force of expanded bore along the lozenges of wedge I
Upper end, then allow for pile crown by an active force obliquely.When bending strength of this active force more than pile crown,
Pile crown will produce horizontal crackle from the both sides of expanded bore, until pile crown is broken.
Used as optimization, the expanded bore is rectangular opening, and a lozenges wedge-like engagement of the wedge I has wedge
II, the heavy in section end of wedge II is located in the expanded bore, and small bore end is stretched out in outside the pile body, wedge I and wedge
II each back to lozenges fitted with two internal faces up and down of expanded bore respectively.Single wedge I is squeezed to expanded bore
When pressure, the position for only being contacted with expanded bore can transmitting forces.Set again on a lozenges of wedge I
One with the wedge II of its wedge-like engagement, two support or oppose of wedge lozenges is fitted in rectangle expanded bore respectively
Two inwalls up and down on, during such wedge I is extruded, wedge II is transferred the force to first, then by wedge shape
Block II passes to pile crown, and impetus is transferred on the hole wall of expanded bore by the orifice position of expanded bore, and torque is converted, and more can
Enough it is broken pile crown.
Used as optimization, the expanded bore is multiple and the circumferential uniform intervals along the pile body are set, each described expansion
The expanding part is provided with hole.Active force is applied to pile crown by multiple orientation, it is easier to be that pile crown is broken.
In sum, the beneficial effects of the utility model are：The utility model simple structure, it is easy to use, by right
Expansion bore expansion makes expanded bore produce breach, and then is broken pile crown, while pile body does not result in damage yet.
