[0034] The specific usage and function of this embodiment are as follows:

[0035] In this utility model, the precast pier 2 is lifted by a crane during use. During lifting, it is crucial to ensure the lifting points are chosen appropriately to prevent the precast pier 2 from tilting or deforming. The precast pier 2 is then lifted above the support 1. As the precast pier 2 descends, the guide components 3 symmetrically arranged at four points on the top of the support 1 begin to function. The guide block 303 at the top of the L-shaped support frame 302, with its inclined side structure, provides initial guidance for the precast pier 2, allowing it to quickly approach the correct installation position. Simultaneously, rotating rollers 3 arranged in a straight line inside one side of the support frame 302... 04 is fitted to the outer side of the precast pier 2. As the precast pier 2 descends, rolling friction reduces resistance, allowing for smoother movement. Furthermore, the guide hole 203 on the bottom side of the precast pier 2 has a conical structure, which better engages with the connecting steel bar A102 on the support 1, further guiding the precast pier 2 into precise positioning. This ensures accurate alignment between the positioning hole 202 on the bottom side of the precast pier 2 and the connecting steel bar A102 on the support 1. The prepared high-strength grout is filled into the grouting groove 101 on the inner side of the top of the support 1, ensuring the grout completely fills the groove. 101, and the surface is flat; then continue to lower the precast pier 2, so that the bottom of the precast pier 2 is in contact with the top of the support 1, and the high-strength grout filling the grouting groove 101 is in contact with the bottom of the precast pier 2; high-strength grout is injected into the positioning hole 202 through the lower grouting hole 205 and the upper grouting hole 206 opened on the bottom side of the precast pier 2; the lower grouting hole 205 and the upper grouting hole 206 are both connected to the positioning hole 202 and are arranged in a rectangular array, which can make the grout fill the positioning hole 202 quickly and evenly; during the grouting process, it is necessary to control The grouting speed and pressure should be controlled to avoid air bubbles and voids. At the same time, the flow of grout should be observed. When grout flows out of the upper grouting hole 206, it means that the positioning hole 202 and the reinforcement hole 204 are filled with grout, and grouting can be stopped. This ensures that the precast pier 2 and the support 1 are fixedly connected. By setting up the auxiliary ring frame 401 and the auxiliary holes 402 arranged in a rectangular array inside it, the connecting steel bars A102 and B201 can be accurately positioned and constrained during the pouring process, ensuring that the two are always arranged in a rectangular array.
