It should be noted that, since the bearing platform 10 is formed by pouring concrete, in the actual assembly process, before the concrete for forming the bearing platform 10 is not poured, the positioning bracket 12 is installed, and accurate positioning of the positioning bracket 12 is ensured, then a part of the concrete for forming the bearing platform 10 is poured, so that the positioning bracket 12 is fixed in the concrete, and then the bridge tower 30 is hoisted, so that the outer shell 32 and the inner shell 34 are respectively connected with the corresponding positioning brackets 12.

Therefore, by providing the positioning bracket 12, the outer shell 32, the inner shell 34 and the positioning bracket 12 are integrally stressed together, thereby increasing the anchoring length of the outer shell 32 and the inner shell 34 in the bearing platform 10. Wherein, the anchoring length refers to the length of the stressed steel bar of the component wrapped in the concrete. Therefore, by providing the positioning bracket 12, the anchoring length of the outer shell 32 and the inner shell 34 is increased, so as to enhance the connection between the bridge tower 30 and the concrete for forming the bearing platform 10, and the bridge tower 30 and the bearing platform 10 can work together to bear larger stress, so that the connection structure between the bridge tower and the bearing platform is more stable.

In this way, since the bridge tower 30 transmits the load to the positioning bracket 12, the load that can be borne by the column 13 is increased by arranging the lengthwise extending direction of the column 13 to be parallel to the lengthwise extending direction of the bridge tower 30, thereby increasing the bearing capacity of the positioning bracket 12. By arranging a plurality of inclined struts 14, the inclined struts 14 and the upright columns 13 share the load transferred by the bridge tower 30, and the reliability of the positioning bracket 12 is further increased.
