Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a prefabricated bearing platform used for bridge processing. Background Art

[0002] Elevated bridges require the use of a large number of high-pile caps. The cap is the connecting part between the pile and the column or pier. The cap connects several or even more than a dozen piles to form a pile foundation. The cap is divided into a cap foundation high-pile cap and a low-pile cap. The high-pile cap is generally exposed to the ground or water surface. A detachable external body is provided on the outside of the cap to protect the cap itself, which effectively avoids the cap being eroded by water for a long time and the problem of damage caused by sudden force. However, the outer shell will be dented when subjected to long-term external impact, which reduces the service life of the cap and cannot effectively protect the outer shell and the cap. Among them, a steep slope bridge cap structure with application number "CN202222417698.X" is disclosed. The utility model A steep slope bridge pier structure is disclosed. By setting supporting columns, telescopic columns, a first protective plate, a triangular reinforcement plate and a third protective plate, two first protective plates and two second protective plates respectively protect the four sides of the outer shell, thereby increasing the stability between the second protective plate and the third protective plate. When pressure is applied to the first protective plate, the force is transmitted to multiple telescopic columns, and the multiple telescopic columns will gradually telescope and move toward the inside of the corresponding supporting columns. However, there is still some improvement in the construction process of the pier: the pier structure is a cast-in-place construction, which requires on-site formwork and casting. Affected by the site, some construction requirements have little impact on the surrounding environment and traffic, and the construction period is shortened as much as possible. There is a great demand for prefabricated and assembled piers, so prefabricated piers are widely used in construction. Utility Model Content
