[0026] A connecting ring 103 rotates at the top edge of the support body 101 via a rotating block and a rotating groove. A scraper 104 is fixed to the outer surface of the support body 101 via mounting bolts on the lower edge of the connecting ring 103. A bearing blade 105 is fixed to the bottom end of the scraper 104. The impact of water flow applies force to the bearing blade 105, causing the scraper 104 to rotate in contact with the outer surface of the support body 101. Simultaneously, the top of the connecting ring 103 rotates at the top edge of the support body 101, ensuring stable rotation of the scraper 104 for safe cleaning. The support structure main body 100 also includes:

[0027] The reinforcement fixing mechanism includes a rotation adjustment component installed inside the pier body 101. A clamping component one is provided at the connection between the bottom outer surface edge of the rotation adjustment component and the conical seat 108, and a clamping component two is provided at the connection between the bottom inner surface edge of the rotation adjustment component and the outer surface of the pier 102. After the pier 102 is installed through the pier structure body 100, the reinforcement fixing mechanism strengthens and fixes the pier body 101, the pier 102 and the conical seat 108, facilitating installation and reinforcement fixing.

[0028] To facilitate simultaneous and convenient installation of the pier 102 and the conical seat 108 during adjustment using the rotating adjustment assembly, in this embodiment, preferably, the rotating adjustment assembly includes an internal thread structure 1023 formed on the inner surface of the pier body 101. An external threaded ring 1021 is threadedly connected to the inside of the pier body 101 through the internal thread structure 1023. The top edge of the external threaded ring 1021 has an internal hexagonal hole 1022. A wrench can be engaged inside the internal hexagonal hole 1022 to rotate the external threaded ring 1021 through the internal thread structure 1023, thereby adjusting, pressing, and reinforcing the installation of the external threaded ring 1021.

[0029] To facilitate the reinforcement and installation between the support body 101 and the conical seat 108 using the clamping assembly, and to make installation and use more convenient, in this embodiment, preferably, the clamping assembly includes an inner arc-shaped clamping ring 1025 welded and fixed to the edge of the outer surface of the bottom end of the external threaded ring 1021. The inner surface of the bottom end of the inner arc-shaped clamping ring 1025 forms an arc-shaped structure 1026. The surface of the arc-shaped structure 1026 is in contact with the surface of the conical seat 108. When the external threaded ring 1021 is rotated, the inner arc-shaped clamping ring 1025 drives the arc-shaped structure 1026 to press against the surface of the conical seat 108 to reinforce and install the conical seat 108, and to facilitate installation and use.

[0030] To facilitate the compression and reinforcement installation between the outer surfaces of the pier cap 101 and the bridge pier 102 using the second clamping component, in this embodiment, preferably, the second clamping component includes an outer arc-shaped ring 1028 disposed on the outer surface of the bridge pier 102. Both ends of the outer arc-shaped ring 1028 are integrally provided with mounting rings 1027. The mounting rings 1027 are fixed to the outer surface of the bridge pier 102 by mounting bolts. The outer arc-shaped ring 1028 is fixedly installed on the outer surface of the bridge pier 102 by the mounting rings 1027. An inner arc-shaped pressure ring 1024 is welded and fixed to the inner edge of the lower surface of the outer threaded ring 1021, and the inner arc-shaped pressure ring 1024 is in compression contact with the surface of the outer arc-shaped ring 1028. When the outer threaded ring 1021 is screwed in, it causes the inner arc-shaped pressure ring 1024 to be pressed against the surface of the outer arc-shaped ring 1028, facilitating a stronger and more secure installation between the pier cap 101 and the bridge pier 102, making it more stable for use.

[0031] An enlarged area support mechanism is provided, which includes an enlarged area support component disposed on the outer surface of the load-bearing pile foundation 106 at the bottom end of the pier body 101. A fixed installation component is provided at the connection between the enlarged area support component and the lower surface edge of the pier body 101. When the pier body 101 is supported by the load-bearing pile foundation 106, the enlarged area support mechanism increases the area of ​​the bottom end of the pier body 101 to strengthen the support, making the installation and use more stable.

[0032] To facilitate the use of the enlarged area support assembly for supporting the pier body 101 with the load-bearing pile 106, in this embodiment, preferably, the enlarged area support assembly includes a main limiting ring 1061 welded and fixed to the outer surface of the load-bearing pile 106. The upper surface of the main limiting ring 1061 is located on the outer surface of the load-bearing pile 106 and a fixing plate 1062 is fixed to it by mounting bolts. An auxiliary load-bearing rod 1063 is welded to the edge of the upper surface of the fixing plate 1062. An installation groove 1064 is provided on the lower surface of the pier body 101. The top end of the auxiliary load-bearing rod 1063 engages with the installation groove 1064. After the fixing plate 1062 is supported and reinforced on the outer surface of the load-bearing pile 106 by the main limiting ring 1061, the auxiliary load-bearing rod 1063 is engaged inside the installation groove 1064 to provide auxiliary support for the load-bearing pile 106, thereby increasing the area for reinforcement and support.

[0033] To facilitate the reinforcement of the auxiliary load-bearing rod 1063 to the bottom of the support body 101 after installation using a fixed installation assembly, in this embodiment, preferably, the fixed installation assembly includes an auxiliary limiting ring 1065 welded and fixed to the outer surface of the auxiliary load-bearing rod 1063. A fixing bolt 1066 passes through the interior of the auxiliary limiting ring 1065. The lower surface of the support body 101 has an internal threaded hole 1067 that is rotatably connected to the fixing bolt 1066. After the auxiliary load-bearing rod 1063 is engaged inside the mounting groove 1064, the fixing bolt 1066 can be rotated to embed into the internal threaded hole 1067 to reinforce and install the auxiliary load-bearing rod 1063, facilitating the installation and fixed support.

[0034] The working principle and usage process of this utility model are as follows: When using this bridge construction pier structure, firstly, the load-bearing pile 106 is driven into the deep underground layer. The bottom end of the load-bearing pile 106 penetrates the pier body 101 and is engaged inside the positioning hole 107. Then, the bottom end of the pier 102 is embedded into the pier body 101 and fixedly installed with the conical seat 108. Thus, the pier 102 is fixedly installed and supported by the pier body 101. When there is debris on the surface of the pier body 101, the impact of the water flow can apply force to the bearing blade 105, causing the scraper 104 to contact the outer surface of the pier body 101 and rotate. At the same time, the top of the connecting ring 103 rotates at the top power edge of the pier body 101, so that the scraper 104 rotates stably to clean up the debris safely.

[0035] Then, when the main body 100 of the pier structure is installed before use, the fixing plate 1062 can be fitted onto the outer surface of the load-bearing pile 106 and supported by the main limiting ring 1061. The fixing plate 1062 is then fixed and installed again. After installation, the auxiliary load-bearing rod 1063 is engaged inside the installation groove 1064. The auxiliary limiting ring 1065 is brought into contact with the lower surface of the pier body 101. The rotating fixing bolt 1066 is embedded inside the internal threaded hole 1067, which facilitates the installation of the auxiliary load-bearing rod 1063 to increase the area and strengthen the support at the bottom of the pier body 101. When the main body 100 of the pier structure bears the load on the pier 102, the support is more stable and the load-bearing surface is increased during long-term installation and use, making it more stable and improving the stability of the support at the bottom of the pier body 101 during bridge construction.

[0036] Finally, after the pier 102 is fixedly installed inside the pier cap 101, the wrench is engaged again inside the internal hexagonal hole 1022. The internal thread structure 1023 drives the internal hexagonal hole 1022 to rotate inside the external threaded ring 1021. As the external threaded ring 1021 rotates downwards, it presses against the surface of the conical seat 108 through the arc-shaped structure 1026, reinforcing the conical seat 108. The inner surface of the inner arc-shaped pressure ring 1024 then presses against the outer arc-shaped ring 102. The surface of the 8-shaped seat facilitates the compression and reinforcement of the bottom end of the external threaded ring 1021 with the outer surface of the pier 102. This facilitates the double reinforcement installation of the pier 102, the external threaded ring 1021, and the pier cap 101 during fixed installation, resulting in greater stability after installation. It also facilitates the reinforcement installation of the pier 102, improving the convenience and stability of the adjustment and installation of the pier cap 102 and the conical seat 108 within the pier cap 101 during bridge construction.
