Description
Technical field
The invention belongs to the realm of building construction, more particularly, to a kind of implanted prefabricated pile grouting device and implanted slip casting
Technique.
Background technology
Existing construction of prefabricated piles technology has hammering method and static pressure method.Hammering method is that prefabricated stake is driven underground with sledgehammer,
It is a kind of most traditional piling method, but because noise is very big, and vibrate and the ground nearby built may be damaged, therefore
And forbid driving piles in this way in city at present.Static press piling is the mode that counterweight is conducted oneself with dignity or added with stake machine, will be prefabricated
Stake is pressed directly into underground, this method is almost without noise, but because harder rock stratum can not be squeezed into, in the place that rock stratum is shallow
It is general inapplicable, and to geologic requirements than more uniform, otherwise easily (prefabricated pile is because pressure is excessive or the effect of being hit is quick-fried for quick-fried stake
Split).Bored concrete pile is opposite with prefabricated pile, is to produce a stake holes using the instrument such as drill bit or stake cylinder, afterwards by concrete
Pour into underground and stake is directly now made in underground, almost can be adapted for the pile foundation construction of all occasions, but because of underground feelings
Condition can not detect, so higher to technological requirement, otherwise easily occur collapsing hole, inclined footpath, the problem of broken pile is a kind of.Bored concrete pile at the same time
A large amount of mud can be produced in construction, to site operation environmental effects, are unsatisfactory for the requirement instantly to environmental protection.
It is currently used plant piling method be：
A. pile-grafting machine is in place：Simultaneously centering is in place to fixed pile is referred to for pile-grafting machine；
B. hole operation is drawn：Start pile-grafting machine, the drilling rod of pile-grafting machine is sunk along leading truck, the drilling rod for starting pile-grafting machine is drilled into
Projected depth；
C. lifting whitewashing stirring：Lifting pile-grafting machine drilling rod, open and send stock pump, to the soil body water-spray type slurry for referring to fixed pile, plants
The drilling rod of stake machine water-spray type slurry and stirring concrete earth in lifting；
D. sink to stirring：Pile-grafting machine lifting drilling rod is whitewashed to ground, is sunk again and is started pile-grafting machine stirring concrete earth；
E. second lift whitewashing stirring：The operating process of step c is repeated, then pile-grafting machine drilling rod is displaced to next position weight
Multiple a steps and b step, unload pore-forming drilling rod to aperture, wait to whitewash, stir and pile sinking；
F. pile-grafting machine returns lifting pile-sinking device and pile pile in situ：Pile-grafting machine lifts pile-sinking device, and lifting pile pile enters b step and draws
In hole；
G. screw in and plant stake：Pile pile is screwed in and has been stirred in molding stake holes；
H. pile extension working face is reserved；
I. Jointing：Electric welding stake is used between section pile crown up and down, to prevent pile body from falling, sets clip to fill in aperture
Put, lower section pile body is encircled after fixing and connect section stake；
J. it is once again screwed into plant stake：The pile body connected is once again screwed into soil cement to designed elevation；Operation, which finishes, to be moved to
Next stake position for having sunk to pore-forming drilling rod, carries out next section pile driving construction.
The plant piling method first carries out counterbore with cement mixing, and a large amount of displacement mud waste of resource can be produced in whipping process
And pollution environment, while pile body section and cement is not required, therefore also result in the waste of resource.
The content of the invention
In view of this, the present invention is directed to propose a kind of implanted prefabricated pile grouting device, solves and exist in the prior art
