A kind of prestressed concrete pipe pile that has ground device
Technical field
The utility model relates to a kind of prestressed concrete pipe pile, relates in particular to a kind of prestressed concrete pipe pile that has ground device.
Background technology
In power engineering,, often to utilize the part of pile body reinforcing bar as ground connection in order to reduce ground resistance.
Owing in the pile body of cast stake, adopt reinforcing cage usually, therefore, can in reinforcing cage, reserve one to two reinforcing bar power supply gas ground connection easily and use, this technology has obtained general application in various castinplace piles.
In the present widely used prestressed concrete pipe pile, mostly be hollow structure, its inner reinforcing bar two ends are separately fixed on the termination ring steel plate that the pile tube two ends are provided with, and the welding by termination ring steel plate between pile tube and the pile tube realizes being connected.Because it has plurality of advantages such as cheap, reliable in quality, easy construction, has obtained application more and more widely.But this kind prestressed concrete pipe pile has also produced new problem, promptly in the construction, because various needs often will cut stake to the stake that the scene has been accomplished fluently.In cast stake in the past, because the concrete intensity of pile body is lower, and pile body is solid, so can adopt the mode of cutter stake, cutter removes the concrete of pile body and keeps reinforcing bar, so that carry out ground connection disposal.And for prestressed concrete pipe pile, its pile body concrete strength height, and be hollow shape, cut stake as still adopting cutter stake mode, at first be that speed is slow, moreover, damage the structure of pile body easily, thereby destroy its mechanical performance.Therefore, the mode that adopts at present is the mode with machine cuts substantially.But the pile body cross section is very smooth after the machine cuts, and the reinforcing bar cross section of exposing is very little, can't draw the welding of ground connection reinforcing bar at all, so also just produced the difficult problem that the prestressed concrete pipe pile flat nick can't weld the ground connection reinforcing bar.
The utility model content
The utility model provides a kind of prestressed concrete pipe pile that has ground device at the drawback of prior art.
The prestressed concrete pipe pile that has ground device described in the utility model comprises pile body, and described pile body is provided with a plurality of pointed bodies with interior space, and the sharp body direction of described pointed body down, is welded with the ground connection reinforcing bar on pointed body.
In the prestressed concrete pipe pile that has a ground device described in the utility model, described pointed body is the triangle iron plate of bending.
In the prestressed concrete pipe pile that has a ground device described in the utility model, by sharp body direction pointed body down is set, make under the prerequisite that does not influence piling technology, increased the area of pile body, and be convenient to improve the operation ease of prestressed concrete pipe pile ground connection by this pointed body welding ground connection reinforcing bar.
Description of drawings
Fig. 1 is the structural representation that has the prestressed concrete pipe pile of ground device described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the manual literal to make those skilled in the art.
As shown in Figure 1, the prestressed concrete pipe pile that has ground device described in the utility model comprises pile body 1, and described pile body 1 is provided with a plurality of pointed bodies 2 with interior space, and the direction of the sharp body 3 of described pointed body 2 down, is welded with ground connection reinforcing bar 4 on this pointed body 2.Wherein, described pointed body 2 is preferably the triangle iron plate of bending.
In the prestressed concrete pipe pile that has a ground device described in the utility model, described pointed body 2 should be connected with the reinforcing bar in the prestressed concrete pipe pile, can realize the ground connection of reliable pile tube.In the prestressed concrete pipe pile that has a ground device described in the utility model, by sharp body direction pointed body down is set, make under the prerequisite that does not influence piling technology, increased the area of pile body, and be convenient to improve the operation ease of prestressed concrete pipe pile ground connection by this pointed body welding ground connection reinforcing bar.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in manual and the embodiment, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the utility model is not limited to specific details and illustrates here and describe.
