Technical scheme, smart structural design, by setting up four fixture blocks fastened with the sleeve pipe of setting on screw pile rig, by spiral
The strength that stake rig is produced is distributed on four fixture blocks, uniform force, the situation of pile pipe easy fracture when improving existing piling.
2. technical scheme
To reach above-mentioned purpose, the technical scheme that the utility model is provided is：
It is of the present utility model it is a kind of can prevent drive piles when pile pipe fracture spiral ground pile, including in cylindrical shape pile pipe,
Helical blade is arranged with described pile pipe；The front end of described pile pipe forms pointed cone portion；The rear end of described pile pipe is along same
Circle distribution is welded with four fixture blocks to fasten with the sleeve pipe of setting on screw pile rig；The rear end of described pile pipe and
Fixture block lower section is provided with four through holes, wherein three through holes are distributed along same even circumferential, and three through hole outsides are welded
It is connected to nut.
Further, described pointed cone portion has 9 top-down cutting crest lines；Offer in described pointed cone portion
Exhaust hole.
Further, the bottom of described pile pipe and middle part distribution is welded with helical blade, and the helical blade is opening
Bung flange shape.
3. beneficial effect
The technical scheme provided using the utility model, compared with existing known technology, is had the advantages that：
(1) it is of the present utility model it is a kind of can prevent drive piles when pile pipe fracture spiral ground pile, the rear end of its pile pipe is along same
Circle distribution is welded with four to the fixture block fastened with the sleeve pipe of setting on screw pile rig, and screw pile rig is produced
Strength is distributed on four fixture blocks, uniform force, and pile pipe rotating repeatedly will not damage pile pipe when producing impact, it is to avoid occur
The section of bolt hole produces dislocation skew the deformation even problem of tear, and quick for installation between pile pipe and screw pile rig, and
The size of fixture block can be designed as needed；
(2) a kind of spiral ground pile of pile pipe fracture when can prevent from driving piles of the present utility model, the rear end of its pile pipe and is located at
Fixture block lower section is provided with four through holes, and each through hole is located at immediately below above-mentioned fixture block, wherein three through hole outsides are welded with spiral shell
Mother, wherein three through hole outsides are welded with nut, the nut only alone may act as the connector fixed with outer body structure；
(3) spiral ground pile of a kind of pile pipe fracture when can prevent from driving piles of the present utility model, its pointed cone portion has 9 from upper
And under cutting crest line, the presence for cutting crest line improves pile pipe and bores the ground efficiency and adaptability to hard soil condition, reduces brill
Ground resistance, pile pipe not easy fracture when can further ensure that piling.
