3) be repeatedly performed above-mentioned steps 2) hammering punch operation, casing is drowned into projected depth；
4) to pressurized delivered concrete in conveying pipeline, concrete fills the pipeline within conveying pipeline and jump bit；
5) while to pressurized delivered concrete in conveying pipeline, lifting up casing, concrete is discharged in the bottom of jump bit, fills stake holes；
6) be performed continuously over above-mentioned steps 5) delivering concrete and lift up casing operation, until casing is proposed foundation surface, in stake holes formed concrete pile body；
7) according to base structure form, subsequent construction is carried out by one of following method:
1. time for pile foundation form, in the center of concrete pile body, downward back-pressure or anti-plug steel reinforcement cage are to projected depth；
2., time for composite foundation form, sandstone or concrete or reinforced concrete soil padding are laid at stake top surface；
3., time for composite foundation form, in the construction of stake jacking row wide diameter portion to increase stake top area, sandstone or concrete or reinforced concrete soil padding are re-layed.
Preferably, in the construction method of above-mentioned concrete-pile, above-mentioned steps 2) in, the weight of punching hammer, and promote the height of punching hammer, it is that the requirement according to soil property and impact energy is determined.
Preferably, in the construction method of above-mentioned concrete-pile, above-mentioned steps 4) in, the concrete of pressurized delivered in conveying pipeline, it is possible to substitute with the compound of one or more mixs in cement or rubble or sand or flyash or coarse-fine aggregate.
The constructing device of above-mentioned concrete-pile and the feature of construction method and advantage thereof are in that:
1. the fast efficiency of speed of fulfiling hole is high, making jump bit by punching hammering, the taper of jump bit bottom directly acts on foundation soil body, produces far to be more than the impact energy of foundation soil body ultimate bearing capacity, make the soil body or rock stratum produce impact failure and form stake holes, drive casing integral sinking simultaneously；2. hole quality is good, while casing plays retaining wall effect, is all squeezed into by the soil body being hit bottom stake holes and on hole wall, arrives in and reinforce compacted effect, and therefore the solidness of the hole wall soil body is higher, it is to avoid hole wall collapse and undergauge；3. seriality is strong, pore-forming, soil compaction, retaining wall, pile whole operations once complete, after the operation completing soil compaction pore-forming, casing or more exchange device need not be proposed, the pressure being made directly pile concrete fills, and the fast efficiency of speed is high；4. applied widely: all applicable under the various geological conditions such as weak soil, hard formation, interlayer, water content height, all applicable in pile foundation construction and complex ground treatment.
