Description
Technical field
Exempt to beat tubular pole and lower stake device the present invention relates to the bitubular, belongs to construction material and construction field.
Background technique
The end of the sixties in last century, Fengtai Bridge Factory, the Ministry of Railways start to produce pretensioned prestressed concrete pipe pile (referred to as
PC tubular pole), it was mainly used for the infrastructure of railway bridge engineering at that time；Development and production seventies post stressed concrete pipe
Stake.Since the seventies, especially in the construction of Shanghai Baoshan steel plant, the steel-pipe pile of Japanese introduction is largely used, has not only been made
Valence is high, and durability is also poor.In order to adapt to the needs of port construction development, 1987 year traffic portion, three boat office is pre- from Japanese a full set of introduction
Stress high-strength concrete tubular pile (abbreviation PHC tubular pole) production line, the main specifications of PHC tubular pole are vertebra 600mm~vertebra
In the 1000mm.80 later period in age, Ningbo East Zhejiang province cement products Co., Ltd and related scientific research institutions cooperate, for China's Coastal Areas
The characteristics of mud Unfavorable geology, develops pretensioning prestressed concrete thin-wall pipe pile (referred to as by the transformation to PC tubular pole
PTC tubular pole), the main specifications of PTC tubular pole has vertebra 300mm~vertebra 600mm.1989~1992 year, former State Bureau of Building Materials Industry Suzhou
Concrete water mud product research institute and bridge abundance of water mud product Co., Ltd, Fanyu city are according to the actual conditions in China, by introduction
The digestion and absorption of tubular pole production line, the prestressed high-strength concrete pile of independent development production domesticization, this achievement quilt in 1993
The former Ministry of Construction is included in national key popularized project.
Existing tubular pole is generally by the way of piling or stake under the mode of static pressure, the mode of piling damage tubular pole
Greatly, noise is big, is not suitable in municipal construction；It is long the time required to the mode of static pressure, and static pressure machine volume is big, carries not；In addition,
It needs more root canal piles carrying out pile extension in construction work, to reach scheduled depth, existing pile extension mode is generally using weldering
It connects and followed by beats or the mode of static pressure.CN201310334690.X discloses a kind of pile extension device for concrete pipe pile, including left steel
The sleeve that plate and right steel plate are constituted, the left plate and right steel plate are semi-cylindrical and its internal diameter is identical as tubular pole outer diameter, described
The both sides of the edge of left plate and right steel plate are respectively arranged with two pieces of stiffeners, the stiffener and left plate and right steel plate welds,
The edge extended line of any stiffener is provided with several through-holes on the stiffener by the axle center of semicolumn, described
It is provided with fixing bolt on through-hole, lock tube is respectively arranged at the top and bottom of the sleeve, the lock tube is cylinder, described
The internal diameter of lock tube and the outer diameter of sleeve are identical.The tubular pole up and down that need to be connected is inserted into sleeve, is tightened with bolt, above scheme
Although can be used for pile extension, the firmness of its pile extension and two straightness are difficult to ensure, also more difficult construction, danger coefficient
Height, and splicing device is the structure of horizontal evagination, will greatly increase pile driving resistance, while extend out subsequent stake holes, first is that rising
Acting on grabbing less than tubular pole, second is that being difficult to ensure that tubular pole does not deviate.
Summary of the invention
Exempt to beat tubular pole and lower stake device in order to solve the above technical problem, the present invention provides the bitubular.The bitubular is exempted to beat
Tubular pole and lower stake device are using being threaded into principle, and without being beaten and static pressure, the effect of lower stake is good, grabs ground securely, speed
Fastly, tubular pole is hurt small, and tubular pole intensity is high, and the more common tubular pole of the ability of external force resistance and anticorrosive aging is high, and from
The dynamic ability with fast and easy pile extension.
Technical scheme is as follows:
