[0023] It should be noted that the construction process of cast-in-situ bridge piers involves the precise design, fabrication, and erection of formwork, which is a time-consuming and complex process. Once the formwork is erected, the subsequent steps such as concrete pouring, vibration, and curing also require a significant amount of time. These steps not only increase the overall project schedule pressure but may also lead to project delays, thereby increasing additional costs. In addition, the geographical conditions at the construction site (such as terrain, soil conditions, etc.) may also pose challenges to the construction. Since cast-in-situ involves multiple links and steps and is affected by various factors, it is difficult to guarantee the quality of the bridge piers. Any mistake in any link may lead to quality problems of the entire bridge pier and even affect the overall safety of the bridge. Considering the above, it is necessary to develop a precast and assembled bridge pier device to solve the above problems.

[0024] In this embodiment, the pier foundation 1 is the basic part of the entire bridge pier device. It bears the weight of the entire bridge pier and the traffic load of the bridge, provides stable support, and ensures the stability of the bridge pier. The bearing platform 2 is installed on the pier foundation 1 and is used to connect and support the upper pier column. It is designed to be detachable, facilitating installation and maintenance, improving construction efficiency, and reducing construction time. At the same time, it is convenient for subsequent maintenance and replacement. The first pier column 3 is arranged on the bearing platform 2 and is used to support the upper capping beam 4. The first docking member 8 is located at the bottom of the first pier column 3 and cooperates with the limit seat 7 on the bearing platform 2 to achieve the accurate docking of the pier column. Through precast pier columns and docking members, the construction accuracy and efficiency are improved. At the same time, the stability and safety of the pier column are ensured. The capping beam 4 is used to bear the bridge deck, and its bottom is connected to the first pier column 3 through the second docking member 9 to achieve the stable support of the bridge deck. Through precast capping beams and docking members, the on-site casting workload is reduced, the construction speed and efficiency are improved. At the same time, the connection stability between the capping beam and the pier column is ensured. A plurality of second pier columns 5 are symmetrically and fixedly installed on the top of the bearing platform 2 and are used to support the bearing platform 2 to increase its stability. By increasing the number and symmetry of the second pier columns, the stability and bearing capacity of the bearing platform are improved. The first precast assembly block 6 is fixedly installed at the bottom of the bearing platform 2 and is used to connect the bearing platform 2 and the pier foundation 1 to increase the stability and strength of the connection. Through precast precast assembly blocks, the construction efficiency and quality are improved. At the same time, the connection strength between the bearing platform and the pier foundation is enhanced. The limit seat 7 is fixedly installed on the top of the bearing platform 2 and cooperates with the first docking member 8 at the bottom of the first pier column 3 to achieve the accurate docking and fixation of the pier column, ensuring the accurate installation and stability of the pier column, improving the construction accuracy and safety. The reinforcement mechanism is arranged on the bearing platform 2 and the capping beam 4 and is used to enhance the stability and bearing capacity of the capping beam 4. Through the reinforcement mechanism, the stability and safety of the entire bridge pier device are further improved, ensuring the normal use and safety of the bridge.

[0026] In this embodiment, second prefabricated assembly blocks 10 are symmetrically fixed to the top of the pedestal 2 and the bottom of the cap beam 4. These prefabricated assembly blocks provide a foundation for the installation of the load-bearing frame 11, while also increasing the structural strength of the pedestal 2 and the cap beam 4. The prefabricated second prefabricated assembly blocks 10 ensure accurate and stable installation, while improving construction efficiency. Furthermore, the use of prefabricated assembly blocks enhances the overall structural strength of the pedestal 2 and the cap beam 4. The load-bearing frame 11 is assembled onto the corresponding second prefabricated assembly blocks 10. Their main function is to support and reinforce the cap beam 4 to ensure the stability and safety of the bridge. The design of the load-bearing frame 11 allows the weight of the cap beam 4 to be evenly distributed on the pedestal 2, thereby reducing the possibility of single-point force and improving the overall bearing capacity of the bridge. The first anchor rod 12 is set on the corresponding second prefabricated assembly block 10 to limit the load-bearing frame 11. One end passes through the load-bearing frame 11 to ensure the stability of the load-bearing frame 11 and prevent its displacement; the use of the first anchor rod 12 further enhances the connection stability between the load-bearing frame 11 and the second prefabricated assembly block 10, prevents the load-bearing frame 11 from shifting or tilting, thereby ensuring the safety and stability of the entire pier device.

Through the close cooperation between the slots and the bridge deck structure, the overall stability of the bridge is enhanced, and the bearing capacity and safety of the bridge are improved. Raised blocks 14 are provided inside the slots 13. These raised blocks 14 are used to support the bridge deck and ensure a stable connection between the bridge deck and the cap beam 4. The raised blocks 14 increase the contact area between the bridge deck and the cap beam 4, thereby improving the connection strength between the two. The design of the raised blocks 14 helps to prevent the bridge deck from sliding or displacing when subjected to external forces, thereby further improving the stability and safety of the bridge. Easy to install and maintain: the raised blocks 14 serve as the connection point between the bridge deck and the cap beam 4, making the installation and maintenance of the bridge deck more convenient and quick.

[0036] In this embodiment, reinforcing ribs are fixedly installed on the second pier column 5, and the bottom end of the reinforcing ribs is fixedly connected to the top of the pier foundation 1. The design of the reinforcing ribs can significantly enhance the structural stability of the second pier column 5, enabling it to withstand greater loads and stresses, thereby improving the load-bearing capacity and safety of the entire pier device. During natural disasters such as earthquakes, the reinforcing ribs can effectively disperse and resist the stresses generated by seismic waves, reducing the vibration amplitude and displacement of the pier, thereby improving its seismic performance. The arrangement of the reinforcing ribs can optimize the stress distribution of the second pier column 5, prevent damage caused by local stress concentration, and extend the service life of the pier.
