Reinforcement cage stirrup installation construction method achieved through supports

The invention discloses a reinforcement cage stirrup installation construction method achieved through supports. The method includes the following steps that (1) supports are symmetrically arranged at the two ends of a machined cast-in-place pile reinforcement cage, each support comprises a top surface thick steel plate, steel tubes are welded to the lower portions of four corners of each top surface thick steel plate respectively, every two adjacent steel tubes are arranged in a splayed mode, reinforcing hoops are welded to four steel tubes on the lower portion of each top surface thick steel plate, a hanging ring is welded to the central area of each top surface thick steel plate, and a hand chain hoist is hung under each hanging ring; (2) the cast-in-place pile reinforcement cage is hung on the hand chain hoists of the supports, and reinforcement stirrups of the cast-in-place pile reinforcement cage are hung by means of the hand chain hoists; (3) spiral stirrups are installed on the hung cast-in-place pile reinforcement cage. The supports used in the method are easy to manufacture, a few of funds are expended, the construction effect is good, cost is saved and the overall quality of the reinforcement cage is guaranteed.
