The invention discloses a kind of nail shape strength core stakes.Including nail shape strength core and mixing pile, the nail shape strength core is made of circular platform type pile cover and strength core, the strength core is located at the lower section of the circular platform type pile cover and is fixedly connected with the circular platform type pile cover, the strength core is equipped with multiple grooves, the strength core is inserted into the mixing pile, and the bottom surface of the circular platform type pile cover and the top surface of the mixing pile abut against.The present invention can make stake top uniform force using biggish circular platform type pile cover, and preferably coordinate pile soil common action, and bearing capacity is high；Phenomena such as longer concrete stiff core can make bearing capacity, and preferably soil cement conducts downwards, avoids the shallow-layer broken pile occurred in subsequent big load bearing process, stake top destruction.The configuration of the present invention is simple, stock utilization is high, and stability is good, and practical, application prospect is extensive.
Description
Technical field
The present invention relates to the realm of building construction, and in particular to a kind of nail shape strength core stake and its construction method.
Background technique
During Foundation Treatment, consolidated subsoil, and construction technology can quickly be handled using mixing pile technology
Simply, construction noise is small, but conventional cement mixing pile, under larger load action, stake top is easily destroyed, and flexible pile is still fallen within
Scope and bearing capacity it is lower.In order to improve the bearing capacity of cement mixing pile, precast concrete pile core is inserted into cement mixing
In stake, referred to as strength core stake.
Current precast concrete pile core mostly uses round or rectangular cylinder as strength core and squeezes into cement mixing pile, by compared with
Stake top is easy discontinuity when big load, causes strength core deflection, influences the pile quality of strength core stake.Meanwhile traditional strength core
Stake still falls within the scope of monomer stake, it is difficult to play the collective effect of stake soil.
Summary of the invention
A kind of structure is simple in order to overcome the deficiencies in the prior art, the present invention provides, and effect is obvious, can significantly solve
The nail shape strength core stake of problem above and its construction method.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme:
A kind of nail shape strength core stake, including nail shape strength core and mixing pile, the nail shape strength core are made of circular platform type pile cover and strength core,
The strength core is located at the lower section of the circular platform type pile cover and is fixedly connected with the circular platform type pile cover, and the strength core is equipped with
Multiple grooves, the strength core are inserted into the mixing pile, the bottom surface of the circular platform type pile cover and the top surface of the mixing pile
It abuts against.
Preferably, the strength core and the circular platform type pile cover are coaxial.
Preferably, the strength core and circular platform type pile cover are made of concrete.
Preferably, the groove is arranged in pairs, positioned at axisymmetrical of a pair of of groove about strength core of sustained height
Setting, positioned at the interlaced setting of adjacent two pair of a groove of different height.
Preferably, the depth of the groove is the 1/5~1/4 of the strength core diameter.
Preferably, the groove is wedge shape.
Preferably, the diameter of the circular platform type pile cover is 5~25 times of the strength core diameter.
Preferably, the length of the strength core is the 1/4~2/3 of the stirring pile length.
The construction method of above-mentioned nail shape strength core stake, comprising the following steps:
(a) prefabricated nail shape strength core；
(b) smooth location measures pile body position, draws construction contour line；
(c) drilling machine positions, and leveling adjusts verticality, drilling rod is directed at central axes, drilling whitewashing stirring, stirring blade is sunk to
After projected depth, 20 ~ 50cm is promoted, slurry pump is opened by cement slurry indentation soil, is rotated in whitewashing, and repeat to stir up and down
It mixes, obtains mixing pile；
(d) nail shape strength core is vertically pressed into the resulting mixing pile of step (c), is pressed into design position, complete construction.
The beneficial effects of the present invention are:
1, concrete circular bench-type pile cover can preferably coordinate pile soil common action, effectively improve pile body bearing capacity；It can keep away simultaneously
Exempt from pile body when piling to tilt, improves the pile quality of strength core stake.
2, concrete stiff-core body can preferably transmit downwards the load that concrete circular bench-type pile cover is undertaken, effectively
Protection stake top and its shallow-layer part are not susceptible to destroy.
3, the groove for being distributed in concrete stiff core can effectively increase between concrete stiff core and surrounding soil cement
Bite force and frictional force keep the collective effect effect of stake soil more preferable, improve bearing capacity.Symmetrically, upper and lower staggered groove point
Cloth form, so that pile body uniform force in all directions, with good stability.
