Abstract
The invention relates to a prestressed concrete pipe pile with reinforcing rings. The prestressed concrete pipe pile mainly comprises a concrete pipe body and a steel reinforcement cage arranged in the concrete pipe body; and the surface of the concrete pipe body is provided with concrete reinforcing rings integrated with the concrete pipe body at intervals along the axial direction. The prestressed concrete pipe pile is characterized in that steel plates coat the surfaces of the concrete reinforcing rings. Because the steel plates coat the surfaces of the concrete reinforcing rings, the strength of the surfaces of the concrete reinforcing rings is greatly improved, and the concrete reinforcing rings are hardly damaged or hardly fall off when collided outside and are particularly suitable for places requiring exposed concrete pipe piles, such as long piled wharfs of water conservancy projects.
Description
Technical field
The present invention relates to a kind of prestressed concrete pipe pile, particularly a kind of prestressed concrete pipe pile that is applicable to the water conservancy project project.
Background technology
Along with the development of concrete technology, the technology of concrete tubular pile also reaches its maturity, and except that being applied to industry, civilian construction, also is widely used in each field such as bridge, harbour, railway or hydraulic engineering.
The bearing capacity of traditional concrete pile tube only receives the influence of side skin friction and stake end frictional resistance, if will increase bearing capacity, can only realize through increasing caliber or length, has increased construction cost and difficulty accordingly.A kind of concrete tubular pile of surface band reinforcing ring has appearred in the back, and it is at pile tube body surfaces setting reinforcing ring spaced apart vertically, utilizes the friction of reinforcing ring and soil to increase the bearing capacity of pile tube.Its shortcoming is: reinforcing ring and pile tube main body are through the whole manufacturing of concrete moulding; The structural strength of reinforcing ring is lower than the pile tube main body of built-in reinforcing cage, and damage particularly is applied in the water conservancy project project easily; Long piled wharf for example; Concrete tubular pile top is exposed outside, run into extraneous collision after, reinforcing ring very easily damages, peels off.
Summary of the invention
The technical problem that the present invention will solve provides the not prestressed concrete pipe pile of the band reinforcing ring of easy damaged of a kind of reinforcing ring.
For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of prestressed concrete pipe pile with reinforcing ring; Mainly comprise concrete tube body and be located at the reinforcing cage in the concrete tube body; Said concrete pipe surface is intervally distributed with the concrete reinforcing ring with the concrete tube body global formation vertically, and its innovative point is: said concrete reinforcing ring surface is coated with steel plate.
The invention has the advantages that: the surface of concrete reinforcing ring coats steel plate; Make the intensity of concrete reinforcing ring improve greatly; When receiving extraneous collision, not easy damaged, peel off, the long piled wharf etc. that is specially adapted to the water conservancy project project needs the exposed place of concrete tubular pile.
Description of drawings
Fig. 1 is the prestressed concrete pipe pile structural representation of band reinforcing ring of the present invention.
Fig. 2 is along A-A line sectional view among Fig. 1.
The specific embodiment
As shown in Figure 1, comprise concrete tube body 1, reinforcing cage 2, concrete reinforcing ring 3, steel plate 4.
Be provided with reinforcing cage 2 in the above-mentioned concrete tube body 1, be intervally distributed with the concrete reinforcing ring 3 with concrete tube body 1 global formation on concrete tube body 1 surface vertically, be coated with steel plate 4 on concrete reinforcing ring 3 surfaces.
Claims (1)
1. prestressed concrete pipe pile with reinforcing ring; Mainly comprise concrete tube body and be located at the reinforcing cage in the concrete tube body; Said concrete pipe surface is intervally distributed with the concrete reinforcing ring with the concrete tube body global formation vertically, it is characterized in that: said concrete reinforcing ring surface is coated with steel plate.
