Abstract
A gear-shaped hollow precast reinforced concrete pile comprises a concrete pile and a reinforced steel bar inside the concrete pile. The utility model is characterized in that the cross-section of concrete pile body has a hollow gear shape, teeth of the pile body are distributed uniformly and circumferentially, the number of teeth is 3-16 or more than 16 for loads of thousands of tons, the pile bottom is sealed with grout to increase the bearing capacity of pile bottom, and the bearing layer is filled with grout to increase the outer diameter of pile and increase the external friction of pile body. The utility model can increase the bearing capacity of single pile and reduce the consumption of raw materials.
Description
Technical field
The utility model relates to worker China Democratic National Construction Association pile foundation construction technical field, particularly a kind ofly saves most, the gear shape precast hollow reinforced concrete pile of frictional resistance maximum.
Background technology
At present, cast-in-place vibrator pipe sinking cast-in-place pile basis is prone to quality problems, and the pile foundation construction new criteria will be limited use to it now, until progressively being cancelled.Frictional resistance is little, bearing capacity is low, anti-shearing force is poor and prefabricated tubular pile also exists, the high defective of broken pile rate, and rotary drilling, Churn drill exist speed slow, problems such as mud contamination is serious, waste raw material.
Summary of the invention
Deficiency at above-mentioned prior art existence, the utility model provides a kind of gear shape precast hollow reinforced concrete pile, it is made up of concrete pile body and interior reinforcing bar thereof, it is characterized in that: the pile body cross section of this concrete pile is the structure that boring, outside are gear shape.Profile of tooth on the described pile body evenly distributes along circumference, and the number of teeth is generally 3～16, and during greater than a few kiloton, a back number of teeth is strengthened in the stake footpath can surpass 16 teeth, can force the back cover that is in the milk bottom the stake in addition, to add timber pile bottom end load at design bearing capacity.Can also force grouting at the bearing stratum position, add the timber pile external diameter, increase the outer frictional resistance of pile body.
Adopt the utility model can increase substantially bearing capacity of single pile, save a large amount of raw material, the popularization of this utility model meets the spiritual requirement that economizing economy does in China fully, will produce huge economic benefit and social benefit.
Description of drawings
Fig. 1 is the cross-sectional structure schematic diagram of the gear shape precast hollow reinforced concrete pile that provides of the utility model.
The specific embodiment
Reach embodiment in conjunction with the accompanying drawings and describe, but protection domain of the present utility model is not limited to accompanying drawing and embodiment.It can be according to the size of design bearing capacity of single pile, strengthens or reduces stake footpath, the number of teeth and size.
As shown in the figure, the utility model provides saves most, the gear shape precast hollow reinforced concrete pile of frictional resistance maximum is arranged by pile body 1, along the pile body length direction interior main muscle 2a and outer main muscle 2b, be arranged in radially reinforcement stirrup 3 of pile body, scratch muscle 4, dowel 5 and rinforcement bar 6 form, and is all the pile body that concrete constitutes around all muscle.In main muscle 2a be positioned on the wheel hub of gear shape precast hollow stake, outer main muscle 2b is positioned at tooth top portion, interior main muscle 2a and strengthen stirrup 3 and be welded as a whole strengthens being connected by rinforcement bar 6 and dowel 5 between stirrup 3 and the outer main muscle 2b.
Embodiment: as shown in the figure, the pile body amount of concrete is 0.18458m
3/ m is less than the used concrete amount of the cast-in-plase pile of ф 0.5m 0.19625m
3/ m, and its bearing capacity is that promptly its bearing capacity is equivalent to the bearing capacity of the cast-in-plase pile of a ф 0.879m more than the twice of Cast-in-place concrete castinplace pile of ф 0.5m, amount of concrete can save 69.6%, and it is very considerable as seen saving material.
Claims (2)
1, a kind of gear shape precast hollow reinforced concrete pile is made up of concrete pile body and interior reinforcing bar thereof, it is characterized in that: the pile body cross section of this concrete pile is the structure that boring, outside are gear shape.
2, gear shape precast hollow reinforced concrete pile according to claim 1, it is characterized in that: the profile of tooth on the pile body evenly distributes along circumference, and the number of teeth is 3～16.
