Embodiment 2
[0045] Embodiment 2, the difference between embodiment 2 and the above-mentioned embodiment 1 is that the pre-embedded steel pipe in the concrete structure of the pier is formed by a plug joint embedded in the bottom of the concrete pier, and the plug joint is used to connect with the pre-embedded plug in the pier cap. The part connected to the socket is a steel pipe structure, which is equivalent to the pre-embedded steel pipe in the prefabricated bridge crossing; during construction, the prefabricated pier is plugged into the pre-embedded socket in the pier cap through the plug joint at the bottom connect.

The invention relates to a prefabricated pier and bearing platform connecting structure, a construction method, a prefabricated pier and a bearing platform. The prefabricated pier and bearing platformconnecting structure comprises the prefabricated bridge pier and the bridge pier bearing platform, the prefabricated bridge pier comprises a bridge pier concrete structure and a pre-buried steel pipepre-buried in the bridge pier concrete structure, the bridge pier bearing platform comprises a bearing platform concrete structure, and a pre-buried bayonet socket for being connected with the pre-buried steel pipe in an inserted mode is buried in the bearing platform concrete structure. During construction, the prefabricated bridge pier is hoisted to a bridge pier bearing platform, and the embedded steel pipe is installed on the embedded socket in an inserted mode; and then a concrete wet joint can be cast in place at the plug-in joint of the embedded steel pipe and the bridge pier bearingplatform to anchor the embedded steel pipe in the bridge pier bearing platform. The connecting structure is high in shear bearing capacity and rigidity, good in connection integrity, low in steel consumption, capable of effectively reducing the workload of on-site welding and formwork supporting and concrete pouring, easy and convenient to construct and convenient to popularize, and has obvious economic and technical benefits compared with a traditional connection structure of the prefabricated pier and the foundation.
Description
technical field [0001] The invention relates to a connection structure between a prefabricated bridge pier and a cap, a construction method of the connection structure, a prefabricated bridge pier and a bridge pier cap used in the connection structure. Background technique [0002] With the rapid development of my country's economy and the rapid growth of urban population, the traffic volume has also increased, and the road traffic capacity is seriously insufficient. The construction of urban viaducts has also become a measure to relieve traffic pressure. In addition to the basic requirements, it is also necessary to minimize the construction period to reduce the impact on the surrounding traffic and shorten the urban traffic jam time. At present, the pier structure of urban bridges usually adopts cast-in-place construction, and the construction needs to be closed to traffic. In addition, the cast-in-place construction period is long, and the construction quality is not easy ...
