Abstract
The utility model relates to a prestressed reinforced concrete tubular pile capable of drilling in a foundation in a spiral mode. The prestressed reinforced concrete tubular pile comprises a pile body, annular metal connection devices are fixedly connected to the two ends of the pile body, the pile body is provided with a threaded concave groove (convex groove), the bottom face of the lower metal connection device is fixedly connected with an annular pile head, the diameter of the upper end of the pile head is larger than the diameter of the lower end, and the inner diameter of the pile head is equal to that of the pile body. The threaded concave groove (convex groove) and the annular pile head with the bottom fixed are arranged on the surface of the prestressed reinforced concrete tubular pile capable of drilling in the foundation in the spiral mode, difficulty for the pile body to be drilled into the foundation is greatly lowered, and efficiency is improved.
Description
Technical field
The utility model relates to a kind of spiral and pierces the prestressed reinforced concrete pipe pile of ground.
Background technology
In the time of engineering construction, normally prestressed reinforced concrete pipe pile power is squeezed into or static(al) is pressed into ground, while running into the ground of some special geologies, pile tube is difficult to injection, or easily there is pile breaking phenomenon, not only affect construction speed but also affect construction quality, and for when construction prestressed reinforced concrete pipe pile angle and piling piling time have strict requirement, and be easy to occur error.
Summary of the invention
The technical problems to be solved in the utility model is: in order to solve the problem of the prior art existence in above-mentioned background technology, provide a kind of improved spiral to pierce the prestressed reinforced concrete pipe pile of ground, solve common prestressed reinforced concrete pipe pile and can only squeeze into or be pressed into the problem of ground.
The utility model solves the technical scheme that its technical problem adopts: a kind of spiral pierces the prestressed reinforced concrete pipe pile of ground, comprise pile body, pile body two ends are fixedly connected with endless metal linkage, pile body offers screw-type groove (tongue), lower end is fixedly connected with annular pile crown on metal connecting device bottom surface, pile crown upper end diameter is greater than lower end diameter, and pile crown interior diameter equates with pile body interior diameter.
Further, on metal connecting device, offer four installing holes.
Further, pile crown upper end external diameter is identical with pile body external diameter.
The beneficial effects of the utility model are, the prestressed reinforced concrete pipe pile surface that spiral of the present utility model pierces ground is provided with screw-type groove (tongue) and bottom stationary annular pile crown, greatly reduces the difficulty of pile body injection ground and has promoted efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of pile crown.
In figure: 1. pile body, 2. metal connecting device, 3. screw-type groove (tongue), 4. pile crown, 5. installing hole.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of spiral as depicted in figs. 1 and 2 pierces the prestressed reinforced concrete pipe pile of ground, comprise pile body 1, pile body 1 two ends are fixedly connected with endless metal linkage 2, pile body 1 is provided with screw-type groove (tongue) 3, on lower end metal connecting device 2 bottom surfaces, be fixedly connected with annular pile crown 4, pile crown 4 upper end diameter are greater than lower end diameter, pile crown 4 interior diameters equate with pile body 1 interior diameter, further, on metal connecting device 2, offer four installing holes 5, further, pile crown 4 upper end external diameters are identical with pile body 1 external diameter, the prestressed reinforced concrete pipe pile surface that spiral of the present utility model pierces ground is provided with screw-type groove (tongue) 3 and bottom stationary annular pile crown 4, greatly reduce the difficulty of pile body injection ground and promoted efficiency.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on manual, must determine its technical scope according to claim scope.
