The utility model discloses major diameter bored concrete pile comprises steel reinforcement cage and integrative cast-in-place bored concrete pile body, has improved the efficiency of construction of pouring of major diameter bored concrete pile on the one hand, and on the other hand has guaranteed major diameter bored concrete pile's bulk strength, and this structure is simple, and the feasibility is high.
For the convenience of this major diameter bored concrete pile falls smooth preparation implementation of breach structure of elevation, preferred technical scheme is, steel reinforcement cage includes the basic cage body and is located the breach cage body of basic cage body top, the basic cage body is indulged muscle and stirrup by first muscle, second of indulging and is constituteed, and first muscle and the second of indulging is indulged the muscle and is followed the interior week side evenly distributed of stirrup, and just the length of first muscle of indulging > the length that the muscle was indulged to the second, the breach cage body is indulged muscle, breach stirrup and first indulges the part that the muscle upper end extends the basic cage body by the addition and is constituteed, and the muscle is indulged with first the muscle in the interior week side evenly distributed of breach stirrup to the addition, and the upper end of muscle and the upper end of first muscle of indulging flush, and the muscle lower extreme extends to the.
Further preferably, the distance from the lower end of the additional longitudinal bar to the inside of the basic cage body is more than or equal to 500 mm. The connection firmness between the foundation cage body and the gap cage body is improved, and the integral stress consistency of the pile body of the cast-in-place pile is ensured.
Further preferably, the lower end of the additional longitudinal rib is provided with a horizontal bending section, and the length of the horizontal bending section is more than or equal to 500 mm. In order to prevent the additional longitudinal bars from loosening in the use process of the large-diameter cast-in-place pile, the overall firmness of the large-diameter cast-in-place pile is ensured.
Further preferably, the stirrup is a spiral stirrup.
The utility model has the advantages and the beneficial effects that:
1. the utility model discloses major diameter bored concrete pile comprises steel reinforcement cage and integrative cast-in-place bored concrete pile body, has improved the efficiency of construction of pouring of major diameter bored concrete pile on the one hand, and on the other hand has guaranteed major diameter bored concrete pile's bulk strength, and this structure is simple, and the feasibility is high.
2. The utility model discloses steel reinforcement cage simple structure makes this major diameter bored concrete pile fall the feasible height of the breach structure of elevation.
