The present invention above-mentioned many wings shaped pile roll forming construction method, it uses the roll forming device including slurry casting machine, unit head, drilling rod, rolling mechanism, described rolling mechanism by rolling power transmission shaft, spacing guide housings, planet rolling wheel form, described rolling power transmission shaft top is connected fixing with drilling rod, bottom is connected with spacing guide housings by bearing, being provided with several outside described spacing guide housings and guide wing, internal circumference up and down is provided with internal tooth；Described rolling power transmission shaft is provided with eccentric part, and described planet rolling wheel is arranged in the eccentric part of rolling power transmission shaft by bearing, is provided with several rolling wings outside it；Described planet rolling wheel is provided with the protrusion insertion portion coaxially connected with spacing guide housings, and this protrusion insertion portion is correspondingly provided with the external tooth engaged with the internal tooth of spacing guide housings；Described rolling drive axis drives the revolution of planet rolling wheel, the most described planet rolling wheel is round the eccentric part rotation of rolling power transmission shaft, spacing guide housings is coordinated with external tooth by internal tooth, limits planet rolling wheel position relative with it and planet rolling running orbit；It is characterized in that: it comprises the following steps:
(1) by the drilling rod of described roll forming device, rolling mechanism align piles position the brill pressurization that falls, till drilling rod and rolling mechanism do not continue to；
(2) head that turns on the power carries out creeping into and persistent pressure, and by the spacing guiding of spacing guide housings buried, planet rolling wheel starts rolling motion until desired depth, it is achieved many wings shaped pile stake holes is drilled to type down；
(3) promote drilling rod and rolling mechanism 0.4-0.7 rice, make the drill bit door being positioned at the rolling power transmission shaft lower end bottom stake holes open, open the concrete pump of slurry casting machine simultaneously, fill concrete by slurry casting machine；
(4) limit lifting limit rotary drill rod and rolling mechanism, while many wings shaped pile stake holes is carried out secondary rolled molding, continues through slurry casting machine filling concrete, until it reaches ground level location, it is achieved the concrete form of many wings shaped pile；
(5) stop drilling rod and the lifting of rolling mechanism, concrete filling and drilling rod and rolling mechanism rotates；
(6) displacement stake machine, descending reinforcing cage does stake and completes.
The present invention above-mentioned many wings shaped pile roll forming construction method, carries out creeping into and being fixed spacing guide housings also by a housing lock device before persistent pressure at the head that turns on the power in described step (2), limits it and rotates.
The present invention utilizes existing full screw earth auger for main frame, and during use, main frame steel wire rope passes through unit head 3 for creeping into offer axial pressure.Drilling rod 4 top is provided with slurry casting machine 2, concrete perfusion when being used for carrying brill.The present invention uses eccentric rolling principle so that the friction extrusion molding of existing rotation can only be become with circle for principal character change different planet rolling wheel just can be with the different many wings shaped pile of Formation cross-section in the case of fixing spacing guide housings.The milled head part of described planet rolling wheel makes minimum three wings just can roll out minimum three limits to most a few odd plots of land that can be cultivated type many wings stakes to the polygon (or many wing) of most tens wings, if planet rolling wheel does and circular can also roll out circular port.Maximum according to the figure circular area that mathematical principle surrounds with girth, so the circular stake girth that shaped pile compares same area is longer, namely pile side surface area is bigger, so can be significantly increased with native contact area, this makes same concrete amount but can obtain bigger bearing capacity.In other words, same bearing capacity makes the consumption of concrete be greatly decreased.
The present invention constructs rationally, reliable operation, smooth running, and the side surface area of pile is big with sectional area ratio, and soil compaction negative effect reduces, and bearing capacity is greatly improved, and pile quality is good, and efficiency of construction is high.Work progress is due to the reduction of sectional area so that soil compaction effect is greatly reduced the most therewith, decreases the negative effect of Squeezing Soil Pile.This pile-type not only increases side frictional resistance, compares soil sampling pile due also to the feature of not casting makes bearing capacity also can be further enhanced.Not only bearing power increase compared with existing Squeezing Soil Pile, after concrete amount reduces and become rolling soil compaction by friction soil compaction, required drive is also greatly decreased；Efficiency and pile quality are also largely increased.In the case of same bearer power, soil compaction effect is also greatly reduced, and work progress decreases the disturbance to soil and the destruction to Soil structure.
