Auxiliary piling device and auxiliary piling method for concrete pile body

Abstract

The invention relates to an auxiliary piling device and an auxiliary piling method for a concrete pile body. The device comprises an upper jacket, a conical head, a guiding ring body and a fixed seatbody, wherein the upper jacket is detachably clamped at the upper part of the concrete pile body, and the outer circumferential surface of the upper jacket is evenly provided with a plurality of arc-shaped convex strips which extend obliquely from top to bottom; the conical head is fixed at the lower end of the concrete pile body; the outer cambered surface of the conical head is provided with threaded bulges; the inner circumferential surface of the guiding ring body is provided with a plurality of arc-shaped guide slots which penetrate obliquely from top to bottom and correspond to the plurality of arc-shaped convex strips, thus receiving the arc-shaped convex strips which decline along with the concrete pile body when the concrete pile body sinks under impact; the auxiliary piling device and the auxiliary piling method can drive the pile body to rotate when the pile body sinks under impact, so that the threads on the conical head part can be used for feeding; the pile body is underan impact force of the upper end on the one hand, and is under a pull force of a conical body at the lower end on the other hand; a pile body sinking effect is achieved due to the combination of the impact force and the pull force; the phenomenon that the pile body is damaged since the same position of the pile body is excessively impacted.

Description

technical field [0001] The invention relates to an auxiliary piling device for concrete piles and a piling method thereof, belonging to the field of building construction. Background technique [0002] Pipe piles are divided into post-tensioned prestressed pipe piles and pretensioned prestressed pipe piles, prestressed concrete pipe piles (PC pipe piles), prestressed concrete thin-walled pipe piles (PTC pipe piles) and high-strength prestressed concrete pipe piles. Pile (PHC pipe pile). [0003] Pretensioned prestressed pipe pile is a hollow cylindrical slender concrete prefabricated component made by pretensioned prestressing process and centrifugal forming method. It is mainly composed of cylindrical pile body, end plate and steel ferrule. [0004] As an important link in the existing building construction process, piling plays an important role. In the prior art, a pile driver is generally used to drive pipe piles, and the pile driver is composed of a pile hammer, a pil...

AI Technical Summary

Problems solved by technology

Because the pipe pile is generally cylindrical, the existing piling is to hit the pile body straight up and down, the resistance to the pipe pile is extremely high, and the pipe pile needs a large impact force to be driven into the ground, which increases the impact on the pipe pile , great damage to pipe piles
