[0045] In an alternative embodiment of the present utility model, referring to Figure 4 , a reinforcing column 6 is installed at the first end of the upper connecting column 2. The reinforcing column 6 is arranged at an interval from the inserting block 21 and is inserted into the connecting groove 32.
[0046] Specifically, both the upper connecting column 2 and the lower connecting column 3 are arranged as column bodies and have the same outer diameter dimension. When the upper connecting column 2 and the lower connecting column 3 are abutted and connected, the cross-section of the pouring hole is circular, which is convenient for pouring cement.

[0060] In an alternative solution of the embodiment of the present utility model, two groups of insertion blocks 21 and two groups of reinforcement columns 6 are provided at the first end of the upper connection column 2.

Each group of reinforcement columns 6 includes four reinforcement columns 6, and the four reinforcement columns 6 are arranged at intervals along the axial direction of the perfusion hole.

[0062] The provision of multiple insertion blocks 21, connection grooves 32 and reinforcement columns 6 enhances the connection stability between the upper connection column 2 and the lower connection column 3.
[0063] In an alternative solution of the embodiment of the present utility model, the precast pier interface structure further includes a plurality of baffles 4. The two ends of the baffle 4 are respectively used to connect with two pier columns 1; the plurality of baffles 4 are arranged adjacent to each other along the circumferential direction of the upper connection column 2 and surround the outer peripheries of the upper connection column 2 and the lower connection column 3 to enclose a perfusion space for covering the upper connection column 2 and the lower connection column 3; at least one baffle 4 is provided with a connection hole 41, and the connection hole 41 communicates with the perfusion space.
[0064] Specifically, referring to Figure 2 , the two ends of the baffle 4 are respectively clamped with the outer walls of the two pier columns 1, increasing the volume of the perfusion space and making the outer wall of the baffle 4 flush with the outer wall of the pier column 1, ensuring the integrity of the appearance and improving the overall aesthetic performance of use. Further, the pier column 1 is provided with a clamping groove 5, and the baffle 4 is provided with a clamping block, and the clamping block is clamped with the clamping groove 5.
[0065] The outer surface of pier column 1 is provided with a clamping groove 5. Both ends of the baffle 4 are fixedly connected with clamping blocks. The baffle 4 is installed on the outer surface of the pier column 1 through the clamping connection of the clamping blocks and the clamping groove 5, and is located on the outer circumference of the upper connecting column 2 and the lower connecting column 3; a plurality of baffles 4 enclose a cylindrical pouring space on the pier column 1. At this time, the upper connecting column 2 and the lower connecting column 3 are in the pouring space, and cement is poured into their interiors through the connecting holes 41. After the upper connecting column 2 and the lower connecting column 3 are connected, the exteriors of the upper connecting column 2 and the lower connecting column 3 are coated with cement, further improving the connection stability between the upper connecting column 2 and the lower connecting column 3.
[0066] The working principle of the precast pier interface structure is described in detail as follows:
[0067] When connecting the pier column 1, the upper connecting column 2 and the lower connecting column 3 are butted, so that the second pouring groove 31 on the lower connecting column 3 and the first pouring groove on the upper connecting column 2 form a circular pouring hole. At this time, cement is poured through the pouring hole, and the cement slurry flows into the connecting groove 32 through the pouring hole; when the lower connecting column 3 and the upper connecting column 2 are in contact, the inserting block 21 and the reinforcing column 6 are inserted into the connecting groove 32. When the cement enters the connecting groove 32, the cement will coat the inserting block 21 and the reinforcing column 6 and enter the through hole 22 of the inserting block 21, improving the connection stability between the inserting block 21 and the connecting groove 32; through the action of the reinforcing plate 63, the contact area between the reinforcing column 6 and the cement is increased, further improving the connection stability between the upper connecting column 2 and the lower connecting column 3. After the cement pouring is completed, the baffle 4 is connected through the clamping blocks on its surface and the clamping groove 5, so that the baffle 4 forms a pouring space between the pier columns 1 and wraps the upper connecting column 2 and the lower connecting column 3 inside. At this time, cement slurry is poured through the connecting hole 41, so that the cement coats the upper connecting column 2 and the lower connecting column 3, further improving the connection stability between the pier columns 1 and ensuring the aesthetics of the overall exterior.
[0068] The beneficial effects of the precast pier interface structure are described in detail as follows:
[0069] First, through the connection between the pier column 1 and the upper connecting column 2, the connection between the pier column 1 and the lower connecting column 3, the upper connecting column 2 and the lower connecting column 3 are assembled to form a pouring hole. Through the insertion connection of the inserting block 21 and the connecting groove 32, the reinforcing column 6 acts inside the connecting groove 32. Cement is poured through the pouring hole, so that the cement enters the connecting groove 32. Under the connection of the through hole 22 and the inserting block 21, the cement enters the through hole 22. After solidification, the connection stability of the inserting block 21 in the connecting groove 32 is improved. In the connection between the reinforcing column 6 and the inserting plate 62, through the connection of the reinforcing plate 63 and the clamping plate 64, the first fastener 65 is threadedly connected to the inserting plate 62 to realize the support of the installation position of the reinforcing plate 63 on the reinforcing column 6. Under the action of the reinforcing plate 63, the connection stability between the upper connecting column 2 and the lower connecting column 3 after cement pouring is improved, and thus the service performance of the assembled connection between the pier columns 1 is improved.
[0070] In a second aspect, by providing a clamping groove 5 on the pier column 1 and a clamping block on the baffle 4, and inserting and connecting the clamping block and the clamping groove 5, the baffle 4 is installed on the pier column 1 and its position is limited; under the action of the connecting hole 41, it is convenient to pour cement into the gap between the baffle 4 and the upper connecting column 2 or the lower connecting column 3, improving the stability of the connection and use between the pier columns 1, ensuring the integrity of the appearance, and improving the overall aesthetic performance of use.
[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
