As preferably, in the X-shaped cross section of described X-shaped pile body, it is connected to the square-section of square pile body.Four seamed edges of described steel reinforcement cage are positioned at inside the center line of four sides of the square pile body of the square pile body in end and middle part, and in X-shaped pile body, position is the inner side of four wings, and outside reinforcing bar, concrete thickness all should meet the requirement of thickness of concrete cover.
As preferably, described end plate arranges through hole, be used for connecting anchor rib.Anchor rib is fastened on four corner points of square stirrup, so that steel reinforcement cage and pile cover form entirety by welding and/or colligation.
Beneficial effect: a kind of X-shaped cross section of the present utility model and the variable cross-section reinforcement concrete prefabricated pile of square-section combination, has the advantage that
(1) the variable cross-section reinforcement concrete prefabricated pile that a kind of X-shaped cross section of the present utility model is combined with square-section, its X-shaped pile body section pile shaft material specific surface area is big, consumptive material is few, low-consuming, the performance of pile shaft material can be given full play to, improve stock utilization, under same volume concrete amount, improve pile body bearing capacity；
(2) a kind of X-shaped cross section of the present utility model uses the square pile body in end, the structural form of the square pile body of X-shaped pile body and middle part with the variable cross-section reinforcement concrete prefabricated pile of square-section combination, compared with single X-shaped section steel rib concrete pile, end resistance can be effectively improved, reduce stake end stress to concentrate, improve bearing capacity of pile, and be readily transported and stack.
