Preformed pile casing method syndeton, mainly comprise thin wall steel tube concrete pile tube, prestressed concrete pipe pile, for connecting the separated steel casing of thin wall steel tube concrete pile tube and prestressed concrete pipe pile;
Reserve connecting hole in the end of prestressed concrete pipe pile, reserve steel column in the end of thin wall steel tube concrete pile tube, the size of connecting hole and steel column, quantity, size are all mated;
Described separated steel casing comprise two closed after rounded annulus, arrange median septum at separated steel casing inner vertical, reserved through hole on median septum, aperture, the quantity of through hole and connecting hole are consistent;
At the upper and lower of separated steel casing sidewall, median septum, evenly bolt hole is set, at thin wall steel tube concrete pile tube, prestressed concrete pipe pile sidewall, the bolt hole consistent with the bolt hole distribution mode of separated steel casing sidewall and aperture is all set near the position of end;
Then thin wall steel tube concrete pile tube, prestressed concrete pipe pile insert prestressed concrete pipe pile by the through hole steel column of thin wall steel tube concrete pipe pile end portion being passed separated steel casing median septum and carry out being fixedly connected with of horizontal direction, and carry out being fixedly connected with of vertical direction by the bolt hole of bolt insertion thin wall steel tube concrete pile tube, prestressed concrete pipe pile, separated steel casing sidewall.
Aforesaid preformed pile casing method syndeton, is also socketed with cuff in the periphery of separated steel casing;
Aforesaid preformed pile casing method syndeton, the caliber of the width that described median septum extends in the horizontal direction and prestressed concrete pipe pile or thin wall steel tube concrete pile tube is close;
Aforesaid preformed pile casing method syndeton, described cuff quantity is two, is separately positioned on the outside of prestressed concrete pipe pile and thin wall steel tube concrete pile tube during layout;
Described separated steel casing comprise two closed after the rounded and semicircular ring of symmetrical configuration.
The utility model has following feature and beneficial effect:
(1) give prominence to steel column by top pile body and bottom pile body reserves being connected of connecting hole, recycle appropriate cementing agent and assisted bonding, effectively enhance the shear resistance of pile body.
(2) median septum of separated steel casing arranges through hole, and top pile body is given prominence to steel column and run through through hole, enhances the globality between pile body and steel pile casting and stability.
(3) side is by the fixedly separated formula steel pile casting of dormant bolt and pile body, and recycling cuff, by separated steel casing banding, effectively improves the intensity of pile body connecting portion.
(4) the utility model structure is simple, easy for installation.
