Slow falling enter ground in, reach projected depth；
5) start concrete perfusion, start upper pile pulling mould (5) after the concrete for being injected more than 1/3 height of a mould, on side, draw out benefit
Fill concrete；Molding device (1) is pushed down by weight or the deadweight of stake machine, remains motionless；
6) after stake mould (5) is extracted completely, a machine is removed, removes the weight on bearing plate, adjust concrete afterwards；Set according to stake top
Meter absolute altitude, adjusts molding device (1) inner concrete amount；If top of concrete highly beyond designed elevation, digs out part concrete；
If top of concrete is highly less than designed elevation, continue to add a certain amount of concrete into pile crown molding device (1)；Finally make to mix
Solidifying soil top surface absolute altitude reaches designed elevation；
7) after the initial set of pile crown molding device (1) inner concrete, by hanger I (201) and hanger II (301) by pile crown molding device (1)
Ground is extracted, from pile body, then takes molding device (1) away, reach the purpose of pile crown sizing.
5. a kind of cast-in-place concrete pile head shaping equipment according to claim 1,2,3 or 4, it is characterised in that described into
The cross sectional shape of type device (1) is according to pile body section determination to be poured, the cross sectional shape of molding device (1) and stake to be poured
Body section shape is consistent；The cross sectional shape of molding device (1) can be circle, rectangle, X-shaped or Y shape；
6. a kind of cast-in-place concrete pile head shaping equipment according to claim 1,2,3,4 or 5, it is characterised in that described
Molding device (1) sinks to ground and can push realization in bearing plate I (2) and the placement weight of bearing plate II (3), it is also possible to directly by stake
Machine is installed on bearing plate and provides the strength for pushing.
7. a kind of cast-in-place concrete pile head shaping equipment according to claim 1,2,3 or 4, it is characterised in that described into
Die cavity (105) sectional dimension of type device (1) is more than pile body sectional dimension to be poured.
