[0002] In traditional bored pile construction, the steel cage hanging bars are welded to the steel cage for hoisting. After the bored pile is poured, the hanging bars cannot be removed. Currently, most bridge foundations use bored piles. The traditional use of hanging bars causes serious waste of steel bars. A reusable steel cage hanging bar is used. After the bored pile is poured, the bored pile steel cage circulating hanging bar is removed and continued to be used in the next bored pile.

[0004] By adopting the above technical scheme, the hanger is placed inside the steel cage, the clamping ring is facing the outside of the steel cage and clamped on the lower part of the spiral hoop or the closed hoop, so that the limit ring at the bottom is higher than the height of the top of the steel cage, and the auxiliary rod is extended from the limit ring at the top outside the steel cage, passes through several limit rings in sequence, and finally the bottom end extends out of the clamping ring. At this time, the limit rod is stuck above the limit ring at the top, so that the auxiliary rod cannot continue to extend downward. The hanger and auxiliary rod are arranged on the other side of the steel cage according to this method. However, in the above technical scheme, the hanger and auxiliary rod can only lift the steel cage, and its stability is poor during the lifting of the steel cage, and it is difficult to recover the hanging rod device, resulting in reduced construction efficiency of the construction project.

[0005] Therefore, those skilled in the art provide a bored pile reinforcement cage circulating hanger to solve the problems raised in the above background technology. Utility Model Content

The reinforcement plate 5 and the steel plate 204 can be fixed by the fixing bolts 6 to prevent the reinforcement plate 5 from deviating, which would result in poor use of the steel plate 204.

[0024] A U-shaped groove 209 is provided on the front side of the steel plate 204, and the outer surface of the limiting rod 205 is fixedly connected to two first fixing rings 7 and the second fixing ring 8, respectively.
