Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-4, a kind of reinforced PTC perforated pipe stake with ribbing, including PTC tubular pole 1 and from stake top to stake bottom successively
The several groups filtration hole 2 that interval L is opened up, PTC tubular pole 1 are provided with ring at stake top L/2 pile cutoff along stake length direction and are attached to tubular pole
Circular rib 4 on appearance wall, circular rib 4 are equipped with several, successively lay along stake length direction spacing distance L, purpose exists
In the structure by changing tubular pole section increases the contact area of stake soil to a certain extent, improves pile side friction, Neng Goujian
Ultimate bearing capacity of single pile is improved singly and effectively, is equidistantly laid with several the stake week of PTC tubular pole 1 along the setting of stake length direction
Longitudinal rib 3 mentions it is intended that increasing the contact area of stake soil to a certain extent by the structure for changing tubular pole longitudinal direction
High pile side friction, referring to fig. 2, longitudinal rib 3 are arranged alternately for 60 ° in same section along stake circumferential direction interval with filtration hole 2, ginseng
