Description
A kind of building piling machinery.
Seen vibropile machine in the construction work now, the setting method of its column are to increase the perpendicular frame gin pole of a cover on the stake machine, then column are put upside down in stake machine front end, utilize perpendicular frame gin pole to erect again.This perpendicular frame method increases moment, so a stake tail seat must increase counterweight, otherwise a stake machine topples easily, and the place that takies also greatly, the accommodation of a machine is restricted; Be that employed vibrohammer all is to seal pattern again, only be suitable for the plain concrete pile driving construction, promptly make just unusual difficulty of deposited reinforced concrete pile construction for laying reinforcing cage, the exciting force of the vibrohammer of this sealing pattern is limited, the soil property and the penetration capacity that adapt to are also limited, as the soil layer of more difficult injection, just can't penetrate, thereby the pile degree of depth does not often reach designing requirement; The 3rd, employed flapper pile tip all has the export trade ear in stake pipe outside, has increased stake pipe penetration resistance, the penetration capacity of influence stake machine, and pore-forming is also irregular, calculate fullness coefficient to placing of concrete and cause difficulty, and the dismounting of stake point is also inconvenient; It four is that existing vibropile machine can only be made prismatic concrete spouting pile driving construction, and the pile type is single, so vertical bearing capacity of single pile can't improve, the pile concrete Forming Quality also is difficult to control.
The utility model utilizes the intrinsic diagonal brace of column, has formed the perpendicular rack device of diagonal brace, needn't increase perpendicular frame gin pole and counter weight device, just column can be erect forward and occupied ground is little, accommodation is big from the afterbody of stake machine; Vibrohammer is used two same model motor instead, implementation forces synchronous backward to drive, and also is provided with through-hole pipe between two motors, vertically connects whole vibrohammer, and connect with the stake pipe, so just for laying reinforcing cage and hammering device provides condition; Change flapper pile tip into inner ear formula stake point, make stake pipe outside smooth relatively, can reduce stake pipe penetration resistance, pore-forming rule, easy accessibility.In addition, set up a cover hammering device, so as to improving the hammering penetration capability of stake pipe; Utilize hammering device also can do constructions such as expanded bore pile, broken stone pile, also can turn over stake pipe inner concrete, make the pile body moulding closely knit, thereby make the perpendicular frame of a machine and lay reinforcing cage flexible, can do the construction of plain concrete or deposited reinforced concrete pile, can make expanded bore pile, broken stone pile again and utilize this pile frame and diesel hammer is used do the construction that steel concrete gives system stake.
