Prestressed concrete square pile spiral pipe driving device

Abstract

The invention discloses a prestressed concrete square pile spiral pipe driving device which comprises a spiral pipe (1) with a thread structure, a spiral pipe sleeve nut (2), a clamp nut (3) and a fixed screw base (4), wherein the fixed screw base (4) is arranged on the spiral pipe (1), the clamp nut (3) is in threaded connection with the fixed screw base (4), and the spiral pipe sleeve nut (2) is sleeved at the end of the spiral pipe (1). After the prestressed concrete square pile spiral pipe driving device is used, when the spiral pipe is withdrawn, after a socket head wrench and a spiral driving nut are twisted, the pipe is time-saving and labor-saving to withdraw, the inner strength of a concrete square pile can not be damaged, and the quality of a concrete square pile can be guaranteed.

Description

technical field [0001] The invention relates to a driving device for a prestressed concrete square pile spiral pipe. Background technique [0002] The prestressed concrete square pile spiral tube is a mold for forming a hole in a concrete square pile. When making a concrete square pile, the spiral tube is placed in the concrete. After the concrete square pile is formed, the spiral tube is pulled out to form a concrete square pile hole. The original The prestressed concrete square pile spiral tube is a smooth spiral tube. When the concrete square pile is formed, the spiral tube needs to be pulled out manually. Because the spiral tube is stuck in the concrete square pile, it will be difficult to pull out the tube and will damage The internal strength of the concrete square pile affects the quality of the concrete square pile. Contents of the invention [0003] The object of the present invention is to provide a prestressed concrete square pile spiral pipe driving device whi...
