Description
Technical field
The present invention relates to a kind of spiral soil compactions to be perfused concrete pile making method, and more particularly to a kind of spiral soil compaction follows up into hole sleeve
Concrete pile making method is perfused.
Background technology
According to spiral extrusion soil filling pile technical regulation J12203-2012, spiral extrusion soil filling pile includes bidirectional screw soil compaction
Stake and the general name of screw rod pile.Spiral Squeezing Soil Pile is a kind of by large torque power head drive drilling tool rotation soil compaction or half soil compaction pore-forming
Pressure concrete injecting, a kind of construction technology of rear slotting steel reinforcement cage pile.The advantages of this construction technology is：Bearing capacity of single pile is high, can save
Substantial amounts of construction material, speed of application is fast, can save the duration, extrusion soil filling pile, and without mud, the dregs amount of discharge is also very
It is few, it is more environmentally friendly.But this construction technology has the following disadvantages in application process：First, pressure concrete injecting retaining wall pile anti-plug steel
The technological requirement concrete of muscle cage must be filled into ground, otherwise steel reinforcement cage just can not normal mounting in place.Thus there is basement
Engineering, stake top absolute altitude will result in substantial amounts of concrete waste in construction, and can also increase clear chisel in the deeper stake of below ground
The expense of pile crown；Although the 2nd, highly developed at present using the technique of vibrator anti-plug steel reinforcement cage, collapsed by the concrete of construction site
The influence of the unfavorable factors such as degree of falling, steel reinforcement cage verticality and rigidity, the operation level of worker, still unavoidable indivedual steel reinforcement cages
Install not in place, and there also have part steel reinforcement cage that can generate installation in an installation to be not placed in the middle, the phenomenon that protective layer is insufficient.
The content of the invention
It follows up it is an object of the present invention to provide a kind of spiral soil compaction into hole sleeve and concrete pile making method is perfused, spiral can not only be kept
The advantages of extrusion soil filling pile, and the deficiency of spiral extrusion soil filling pile can be solved.
To achieve these goals, the present invention uses following technical scheme：
A kind of spiral soil compaction follows up into hole sleeve and concrete pile making method is perfused, and comprises the following steps:
