Description
Technical field
The present invention relates to a kind of pile foundation construction equipment and construction method, specifically a kind of more wing shaped piles are rolled into
Type device and construction method.
Background technology
At present, bored pile construction is a kind of more universal pile making method in foundation construction field, it is by carrying out
Band or stride pile frame are host, hang up power head and long spire drilling tool forms drilling machine.What is carried out during construction is to replace operation i.e.
A kind of engineering method of steel reinforcement cage is inserted after boring extracting soil, guncreting, since with less, high construction efficiency is invested, pile quality is high, suitable
Ying Xingguang and it is easy to operate pollution-free the advantages that, be popular by unit in charge of construction very much.This engineering method is applicable not only to clay, sand
Soil, is also applied for the higher silt soil layer of water content even fully weathered rock stratum.So the urban architecture in China, or even part bridge
It is widely used in beam basis and high ferro engineering, but more to cover more higher baseline also increasing in building with the development of the city,
The disadvantage of this construction method also gradually displays.The problems such as processing of bottom hole loosened soil, embedding ability is poor, influences the carrying of stake
Power.So this engineering method and existing equipment are difficult to complete when requiring large bearing capacity.As foundation engineering is for pile bearing capacity
It is required that the continuous improvement with environmental protection, Squeezing Soil Pile have gradually obtained attention and development in industry, especially it has high capacity,
Pile quality is good and has obtained certain development and application without the advantages that casting.But since such a engineering method has soil compaction effect, if cloth
Office is improper to be also easy to produce floating stake or make and closes on pile body and the counter productive such as squeeze off, so stake footpath cannot be done greatly, mostly 500 millimeters with
It is interior.When the large diameter friction piles of frictional resistance bigger to be accomplished are difficult to, construction equipment is also very huge, complicated and expensive.So how
Can be in limited sectional area, that is, a perimeter of section is done longer, side surface in the case of identical concrete amount

Axis pressure is provided.4 top of drilling rod is equipped with slurry casting machine 2, concrete perfusion during for carrying brill.The present invention uses eccentric rolling principle,
So that existing rotating friction extrusion molding can only become the different planet rolling wheel of replacement with circle for main feature to exist
Can the different more wing shaped piles of Formation cross-section in the case of fixed limition orientation housing.The milled head of the planet rolling wheel
Minimum three wing is made to the polygon of most more than ten wings in part（Or more wing）Minimum three side can be rolled out to most several odd plots of land that can be cultivateds
The more wing stakes of type, if planet rolling wheel makes circle and can also roll out round hole.The figure surrounded according to mathematical principle with girth
Circular area is maximum, so shaped pile is longer compared to the circular stake girth with area, that is, pile side surface area bigger, so
It can be significantly increased with the contact area of soil, this makes same concrete amount but to obtain the bearing capacity of bigger.In other words, together
The bearing capacity of sample causes the dosage of concrete to be greatly decreased.
Present invention construction is reasonable, reliable operation, smooth running, and for the side surface area of pile with sectional area than big, soil compaction is negative
Effect reduces, and bearing capacity greatly improves, and pile quality is good, and construction efficiency is high.Work progress is due to the reduction of sectional area so that squeezes
Native effect is also greatly reduced therewith, reduces the negative effect of Squeezing Soil Pile.The pile-type not only increases side frictional resistance, compared to soil sampling pile
Due also to the characteristics of not casting, causes bearing capacity to be also further enhanced.Not only bearing capacity carries compared with existing Squeezing Soil Pile
Height, concrete amount are reduced and become by friction soil compaction after rolling soil compaction, and required power is also greatly decreased；Efficiency and pile matter
Amount is also largely increased.In the case of same bearer power, soil compaction effect is also greatly reduced, and work progress is decreased to soil
Disturbance and the destruction to soil texture.
