Abstract
The invention provides a dual-size grid reinforced pipe pile. The dual-size grid reinforced pipe pile comprises a cylindrical pile body; large-size ribs are placed on the outer wall of the pile body annularly and axially at intervals of every multiple small-size ribs, the section height of each large-size rib is larger than that of each small-size rib, and the section of each large-size rib is rectangular or T-shaped. Due to the arrangement of the large-size ribs and the small-size ribs on the outer wall of the dual-size grid reinforced pipe pile, the effective supporting area of the whole pipe pile is effectively expanded, the bearing capacity of the pipe pile is improved, and the pile pressing depth of the pipe pile can be effectively reduced when a condition that the bearing pressure of the pipe pile is changeless is ensured.
Description
Technical field
The present invention relates to concrete product technology, particularly relate to a kind of double yardstick grid reinforcement pile tube.
Background technology
From China in 1987, the introduction of first bar pile tube production line had more than 20 year so far, and along with science and technology and the continuous progress of production technology, the pile tube kind of production and specification are abundanter.The pile tube kind produced at present has: pretensioning prestressed concrete bamboo joint pile (PHDC stake) etc. taken root in by prestressed concrete pipe pile (PC stake), prestressed high-strength concrete pile (PHC stake) and quiet brill.Prestressed high-strength concrete pile is good with its piling quality, intensity is high, resistance to injection, penetration capacity are strong, engineering geology strong adaptability, design Application Range extensively, easily lay out pile, the economic advantage such as quick, easy to detect and be widely used in the basis of the engineerings such as industry and civil buildings, highway, railway, water conservancy, port and pier, municipal administration structures.
Existing prestressed high-strength concrete pile includes the stake body axially extended, stake body is cylinder, this internal reinforcement that is provided with of stake, stake body is provided with the ring projection radially becoming big, and when piling, the ring of projection does not reaches the purpose improving pile tube bearing pressure.
Summary of the invention
It is an object of the invention to, for the problem of above-mentioned existing pile tube bearing pressure difference, propose a kind of double yardstick grid reinforcement pile tube, this pile tube has the bearing capacity of excellence.
For achieving the above object, the technical solution used in the present invention is: a kind of double yardstick grid reinforcement pile tubes, including a body, described stake body is cylinder, described stake body outer wall hoop places a large scale muscle with axial every several little yardstick muscle, the depth of section of described large scale muscle is more than little yardstick muscle, and the cross section of described large scale muscle is rectangle or T-shaped.
Further, the cross-sectional width of described large scale muscle greater than, equal to or less than the cross-sectional width of little yardstick muscle.
Further, described stake inner body wall hoop places a large scale muscle with axial every 2-5 little yardstick muscle.
Further, described stake inner body wall hoop is with axially every several little yardstick muscle one large scale muscle of placement, and the depth of section of described large scale muscle is more than little yardstick muscle, and the cross section of described large scale muscle is rectangle.
Further, described stake inner body wall hoop places a large scale muscle with axial every 2-5 little yardstick muscle.
Further, described stake body two ends have been respectively fixedly connected with jointing.
Further, described stake body is high-strength concrete stake body.
It is appreciated that stake body of the present invention can also be for square-column-shaped or prismatic.
The double yardstick grid riffled tube pilework of the present invention is simple, reasonable, compact, has the advantage that compared with prior art
On the double yardstick grid reinforcement pile tube outer wall of the present invention, the setting of large scale muscle and little yardstick muscle the most only effectively expands effective Area of bearing of overall pile tube, improve the bearing capacity of pile tube, and in the case of guaranteeing pile tube bearing pressure inconvenience, it is possible to efficiently reduce the pile tube piling degree of depth.
The present invention is by arranging large scale muscle and little yardstick muscle by the way of in conventional tube pilework, improve the defect robustness of tradition pile tube, will not produce bigger ultimate bearing capacity reduction when defect a little, simultaneously along with the increase of defect amplitude, ultimate bearing capacity progressively converges on certain certain value.Large scale muscle and the quantity of little yardstick muscle, depth of section, cross-sectional width quickly can be determined by numerical optimization according to indexs such as the diameter of structure, length.
Processing technique of the present invention is simple, is suitable for scale of mass production.
