Embodiment
With reference to embodiment, the utility model will be further described, and described embodiment is only that this practicality is new
A part of embodiment of type, is not whole embodiments.Based on the embodiment in the utility model, the ordinary skill people of this area
Other embodiments used that member is obtained under the premise of creative work is not made, belong to protection model of the present utility model
Enclose.
The reducing multinode churning anti-float anchor rod provided with reference to accompanying drawing, the utility model, including formed by rotary jetting apparatus churning
And the churning pile body in the pore-forming of ground, anchor structure 1, the inside of the anchor structure 1 are provided with the rotary churning pile body
And concrete layer is filled between anchor structure and ground pore-forming, the concrete layer includes alternate successively from bottom to up
First concrete layer 2 and the second concrete layer 3, the cross section of the concrete layer 3 of the first concrete layer 2 and second is in circle
Shape, the external diameter of first concrete layer 2 is more than the external diameter of the second concrete layer 3.
First concrete layer and the second concrete layer of the present utility model are cylindrical, and the first concrete layer and
Two concrete layers are connected with each other and are integrally formed.
Reducing multinode churning anti-float anchor rod of the present utility model, after construction completes churning pile body, in the churning of formation
Anchor structure formation float Structure is immediately inserted into pile body so that total has the vertical function being pressurized with tension, simultaneously
Have both the function of composite foundation and anti-floating, due to the presence of the first concrete layer and the second concrete layer reducing multinode, resistance to compression
Common rotary churning pile and anti-float anchor rod are above with anti-pulling capacity, is particularly suitable for use on the soft foundations such as silt, sand and cobble
And the higher geology of level of ground water is used, compared to existing Unfavorable geology, the utility model shortens construction period and construction
Cost.
As a kind of preferred mode of the utility model, using two-tube or three pipe rotary jetting apparatus, hole is drawn first to designed elevation,
Then churning is carried out to bottom hole under rotary jetting apparatus, bottom hole churning uses two-tube churning, forms the first concrete layer 2 compared with timber pile footpath,
About 1 meter or so of part stake footpath height；Then single tube spinning-jet is used, the second concrete layer 3 compared with paxilla footpath is formed,；Then again
Two-tube churning is up used, the first concrete layer 2 compared with timber pile footpath is formed, with this past up to stake top absolute altitude.Then churning is complete again
Into churning pile body on using vibration insertion anchor structure 1, anchor structure is anchored into water resistant plate and forms float Structure.
As a kind of preferred mode of the utility model, the anchor structure 1 includes fixed support 5, the fixed support 5
Periphery be evenly arranged with least two anchor pole reinforcing bars 6, the periphery of the anchor pole reinforcing bar 6 is arranged with steel reinforcement cage 7；It is used as this practicality
A kind of new preferred mode, the fixed support 5 is also to be formed by binding reinforcing bars.Anchor structure of the present utility model, no
It increase only the adhesion (anchor force) between anchor structure 1 and the soil body 4；Anchor need not be increased by increasing the length of anchor pole
Adhesion between bar structure and the soil body, shortens the length of anchor pole, has saved the cost of manufacture.It it also avoid because anchor pole knot
Structure is due to the situation of the stress concentration caused by length increase on length direction.
