[0019] The following further clarifies the utility model in conjunction with the drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the utility model and not to limit the scope of the utility model.

[0020] As shown in the figure, the temporary fixing platform for installing the steel cage of bored piles described in the utility model includes a fixing ring 1 and symmetrically arranged adjustable hanging ears 2. The fixing ring 1 is a base welded by profiled steel. The adjustable hanging ear 2 includes a positioning steel plate 3, a limiting steel plate 4, and a pulling steel plate 5. The positioning steel plate 3 is vertically fixed on the outside of the fixing ring 1. A long slot 6 is opened below the middle of the positioning steel plate 3. One end of the pulling steel plate 5 passes through the long slot 6. The two limiting steel plates 4 are fixed on the outside of the pulling steel plate 5. A limiting slot 7 is opened above the front end of the pulling steel plate 5.

[0021] For the temporary fixing platform for installing the steel cage of bored piles described in the utility model, during the construction of the steel cage, the fixing ring 1 is fixed on the ground. During the process of hoisting the steel cage into the lower casing, only by pushing the pulling steel plate 5 along the gap between the two limiting steel plates 4 and placing the limiting slot 7 under the reinforcement stirrup, it can be temporarily fixed accurately and quickly. It has a simple structure and is easy to operate, ensuring the quality and safety during the installation process of the steel cage.
