Description

Pre-poured stake and pile making method thereof
Technical field
The invention belongs to building field, particularly to a kind of pre-poured stake and pile making method thereof.
Background technology
At present, construction piling technique during driven cast-in-place pile, the most abroad, the domestic long height by pile frame of stake that all exists limited, the length making stake can not be oversize.Additionally when the stake footpath of driven cast-in-place pile is big, stake is long, not only the difficulty of immersed tube is big, and the time of pouring concrete in-situ is long, extremely difficult when dialling outer tube, so sometimes for increasing bearing capacity, enlarged footing need to be done in bottom, makes a time of making long, when weak intercalated layer is met in enlarged footing bottom sometimes, stake must also be increased long, through weak intercalated layer, further increase and limited by stake machine tower height, make immersed tube, tube pulling difficulty bigger.Prefabricated pile because of stake is long can be with pile extension, stake is long not to be limited by stake machine height, but the cost of real core prefabricated pile is high, there is again shearing strength and be difficult to meet the problem that design requires in hollow pile for prestressed pipe, increases stake long when meeting landing surface and having hard interbedded layer, can produce that the noise of construction is big and pile sinking difficult, and often have quick-fried stake phenomenon, sometimes for drawing hole, causing construction cost high, speed of application is slow.
Summary of the invention
It is an object of the invention to overcome above-mentioned technical deficiency, it is provided that a kind of pile making method is simple, it is ensured that pre-poured stake that pile foundation construction quality, speed of application are fast and pile making method thereof.
The present invention solve technical problem the technical scheme is that the feature of pre-poured stake be bottom be prefabricated pile, top is bored concrete pile;The diameter of the bored concrete pile of its middle and upper part is more than the diameter of the prefabricated pile of bottom and makes bored concrete pile parcel or do not wrap up the upper end of prefabricated pile, it is provided with or does not set concrete or cement mixture filler in the junction of prefabricated pile and bored concrete pile according to design requirement, it is also possible to be that top bored concrete pile diameter is more than bottom prefabricated pile a diameter of docking form;Or the diameter of the bored concrete pile on top is identical with the diameter of the prefabricated pile of bottom;The pile making method of pre-poured stake is as follows:
Pile making method A:Aa, the inner and outer pipe drilling tool align piles position of stake machine, adjust the perpendicularity of drilling tool;Inner and outer pipe drilling tool is sunk to projected depth by the methods such as Ab, employing static pressure, hammering or vibration;Ac, startup hoist engine propose interior pipe drilling tool;Ad, from outer pipe drilling tool sidewall or outer pipe drilling tool top concrete perfusion or cement mixture filler to design height, when using cement mixture filler, start hoist engine and mention interior pipe drilling tool, put back in outer pipe drilling tool, pipe drilling tool in transfering to after using the method compacting fillers such as static pressure, hammering or vibration;Ae, prefabricated pile is sling, put into outer pipe drilling tool;Af, when prefabricated pile use prestressed concrete pipe pile time, pile for prestressed pipe top place band torr steel reinforcement cage, at hollow prefabricated pile top bored concrete pile core concrete, and consolidate by design requirement, it is also possible to omit this step;Ag, take off the movable plate bottom interior pipe drilling tool, interior pipe drilling tool is directed at prefabricated pile top, the perpendicularity of pipe drilling tool in adjusting, use the methods such as static pressure, hammering or vibration, interior pipe drilling tool is sunk to projected depth, pipe drilling tool in then proposing, form bottom prefabricated pile;Put into steel reinforcement cage in Ah, outside pipe drilling tool, irrigate pile concrete, according to design requirement, it is also possible to do not put steel reinforcement cage;Ai, interior pipe drilling tool is put back to the TOC in outer pipe drilling tool, transfer to outer pipe drilling tool to complete the subsequent construction of stake, form pre-poured stake;Aj, when without subsoil water, by design requirement, Ad step can not be taked, complete pre-poured stake;Pile making method B:Ba, stake machine is moved to and align piles position, lift by crane prefabricated pile, adjust prefabricated pile perpendicularity, prefabricated pile is sunk to ground surface;Bb, when prefabricated pile use prestressed concrete pipe pile time, prefabricated pile top place band supporting plate steel reinforcement cage, bored concrete pile core concrete also consolidates, it is also possible to by design requirement, omit this step;Bc, prefabricated pile top will be directed at inner and outer pipe drilling tool, and adjust the perpendicularity of inner and outer pipe drilling tool;The methods such as Bd, employing static pressure, hammering or vibration are sink to projected depth inner and outer pipe drilling tool, and prefabricated pile sinks to projected depth the most therewith, completes construction of prefabricated piles;Pipe drilling tool in Be, dial-out, puts into steel reinforcement cage, and concrete perfusion forms bored concrete pile;Bf, interior pipe drilling tool of slinging, put into the top of outer pipe drilling tool inner concrete, transfers to outer pipe drilling tool, completes the subsequent construction of stake, forms pre-poured stake;Bg, when outer pipe drilling tool diameter is more than bottom prefabricated pile diameter, then form bored concrete pile more than prefabricated pile diameter;Bh, the bottom of bored concrete pile are wrapped up in prefabricated pile top design length range.
The invention has the beneficial effects as follows: pre-poured stake and the prefabricated pile of pile making method thereof and bored concrete pile combination flexibly, are suitable for formation volumes extensive, and bearing capacity of single pile is high, has the strongest practicality.The prefabricated pile of bottom decreases on-site concrete groundwater increment, prefabricated pile diameter is less than bored concrete pile diameter, meet the force-mechanism of stake, save the consumption of concrete, substantially increase speed of application, reduce cost, bottom uses prefabricated pile to solve bored concrete pile because being limited, by stake machine height, the problem that can not play long stake, simultaneously big because of driven cast-in-place pile stake footpath, immersed tube and the problem of tube pulling difficulty when stake is long solve the most accordingly, and the bored concrete pile that uses on top is greatly improved than the shear resistance of prestressing force hollow pile.
