Abstract

The utility model provides a cutting edge type flap valve stake point with lateral extension function comprises pad, pivot underlay, a supporting beam frame hinge, branch hinge, guide pile, crescent top surface, nut, screw rod, branch, pterygoid lamina, pivot hole, pterygoid lamina tension springs in the left lamella of stake point, the sharp right lamella of stake, a supporting beam frame, pivot, the pivot. The utility model discloses a cutting edge type flap valve stake point with lateral extension function, after the stake point arrived the design altitude, cutting edge type flap valve stake point can transversely be opened, and the pile head becomes flat platform form by general taper shape, is difficult for thrusting the soil layer, and guarantee stake end bearing capacity does not slacken, the back is opened to cutting edge type flap valve stake point, extracts when pipe stake, no longer produces the negative pressure, can not cause the disturbance to the stake substratum, does not reduce stake end soil layer intensity, also avoided in saturated sand bed the construction to cause the siphon to intake or the sand boil phenomenon.

Description

There is the blade type flapper pile tip of lateral spread function
Technical field
The utility model belongs to the realm of building construction, specifically has the blade type flapper pile tip of lateral spread function.
Background technology
Tube-sinking cast-in-situ pile has that equipment is simple, easy to operate, cost is low, mud-less pollution, speed of application are fast, with advantages such as geological conditions change strong adaptabilities, also avoid the pile body sinking that general bored pile pile top surface dust causes, hold hypodynamic problem, also effectively improve pile body surface laitance phenomenon simultaneously.Therefore, tube-sinking cast-in-situ pile is the one in civil construction project in numerous type pile foundation.
Tube-sinking cast-in-situ pile normally utilizes pile sinking machine to sink in soil by the pile pipe with flapper pile tip, and then limit is to concreting in pile pipe, shakes while extract pile pipe, concrete is stayed in soil and forms pile body.When running into the construction of soft wetland layer, during upper pile pulling pipe, the following soil body of viscous force double action meeting disturbance flapper pile tip of the larger negative pressure produced below flapper pile tip and soft wet soil layer, makes intensity reduce; The pile crown that valve type pile shoe is formed, for conical, also easily thrusts soil layer, reduces bearing capacity of pile tip; Especially construct in saturated sand layers, if pull out and very easily cause siphon inlet or sand boil phenomenon by force.
Utility model content
In order to solve the above-mentioned technical problem existed in prior art, the utility model provides a kind of blade type flapper pile tip with lateral spread function, be made up of pad, rotating shaft underlay, support beam frame hinge, pole hinge, guide pile, crescent end face, nut, screw rod, pole, wing plate, shaft hole, wing plate tension spring in the left lobe of pile top, the right lobe of pile top, support beam frame, rotating shaft, rotating shaft, the left lobe of described pile top and pile top right lobe upper end circular arc, lower end linear; The left lobe of described pile top and the right lobe upper end of pile top are fixedly installed crescent end face; Crescent end face is fixedly installed guide pile; The left lobe of pile top and the right lobe of pile top are hinged on support beam frame two ends; Rotating shaft by the shaft hole on support beam frame, and is respectively fixedly installed pad, rotating shaft underlay in rotating shaft up and down at shaft hole; Rotating shaft bottom is screw rod; Screw rod there is nut; Nut both sides by pole, hinge respectively at the left lobe of pile top and the right lobe of pile top hinged.
Further, the left lobe of described pile top is with tip, and the right lobe of pile top is shorter than the left lobe of pile top; The left lobe of pile top and the right lobe top of pile top are respectively provided with one block of wing plate, and wing plate side and a pile top lobe are by hinge, and middle part is connected on support beam frame by wing plate tension spring, and wing plate opposite side remains and to fit together with another pile top lobe.
The blade type flapper pile tip with lateral spread function of the present utility model, well can avoid the problems referred to above.Pile top arrives after design altitude, and blade type flapper pile tip can laterally be opened, and pile crown becomes flat mesa-shaped by general taper shape, not easily thrusts soil layer, ensures that bearing capacity of pile tip does not slacken; After blade type flapper pile tip is opened, when extracting pile pipe, no longer produce negative pressure, can not disturbance be caused to stake substratum, do not reduce pile-end soil layer intensity; It also avoid construction in saturated sand layers and cause siphon inlet or sand boil phenomenon.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The blade type flapper pile tip with lateral spread function of the present utility model is made up of pad 5, rotating shaft underlay 6, support beam frame hinge 7, pole hinge 8, guide pile 9, crescent end face 10, nut 11, screw rod 12, pole 13, wing plate 14, shaft hole 15, wing plate tension spring 16 in the left lobe of pile top 1, the right lobe 2 of pile top, support beam frame 3, rotating shaft 4, rotating shaft, the wherein left lobe of pile top 1 and pile top right lobe 2 upper end circular arc, lower end linear, arc radius is less than pipe diameter; The left lobe of pile top 1 and pile top right lobe 2 upper end are fixedly installed crescent end face 10; Crescent end face 10 is fixedly installed guide pile 9; The left lobe of pile top 1 and the right lobe 2 of pile top are hinged on support beam frame 3 two ends; Rotating shaft 4 by the shaft hole on support beam frame 3, and is respectively fixedly installed pad 5, rotating shaft underlay 6 in rotating shaft up and down at shaft hole; Rotating shaft bottom is screw rod 12; Screw rod 12 there is nut 11; Nut both sides are hinged respectively at the left lobe of pile top 1 and pile top right lobe 2 by pole 13, hinge; The left lobe 1 of pile top is with tip, and the right lobe of pile top is shorter than the left lobe of pile top; The left lobe of pile top and the right lobe top of pile top are respectively provided with one block of wing plate 14, and wing plate 14 side and a pile top lobe are by hinge, and middle part is connected on support beam frame 3 by wing plate tension spring 16, and wing plate 14 opposite side remains and to fit together with another pile top lobe; When pile top is closed, top outer rim is greater than pile pipe outer rim, is convenient to pile pipe jacked pile point; When pile top is opened, top outer rim is less than pile pipe inner edge, is convenient to pile top and proposes in pile pipe.
Before pore-forming, the left lobe of pile top and the right lobe of pile top close, and end is blade-like, easily breaks ground.Utilize pile sinking machine to sink in soil by the pile pipe with flapper pile tip, pile top rotates counterclockwise rotating shaft after arriving design altitude, nut moves down, and pole is opened, and the left lobe of pile top and the right lobe of pile top rotate around support beam frame, the horizontal soil compaction of the left lobe of pile top and the right lobe lower end of pile top, forms rectangular pile end face; Top closes up in retraction pile pipe.The blade type flapper pile tip with lateral spread function is proposed pile pipe, and concrete perfusion, tube-sinking cast-in-situ pile completes.
