Fabricated combined bridge pier connecting system and construction method thereof

Abstract

The invention provides a fabricated combined bridge pier connecting system and a construction method thereof, and belongs to the technical field of building parts of roads, railways or bridges. The fabricated combined bridge pier connecting system comprises prefabricated bridge piers, steel members and fasteners, the prefabricated bridge piers are arranged in pairs, the steel members are arrangedbetween each pair of prefabricated bridge piers and connected through the fasteners, each prefabricated bridge pier comprises a steel shell and reinforced concrete, the steel shells are core molds, and spaces formed by the steel shells are filled with the reinforced concrete. The fabricated combined bridge pier connecting system is simple in structure, high in strength, light in dead weight, highin bearing capacity, firm in connection, high in construction speed and convenient to use, fabricated construction can be adopted, and the defects that in existing sleeve connection, the grouting compactness is difficult to control, detection is difficult, and the self-weight of prefabricated members is large can be overcome.

Description

technical field [0001] The application relates to a prefabricated composite pier connection system and a construction method thereof, which belong to the technical field of construction parts of roads, railways or bridges. Background technique [0002] With the further advancement of bridge industrialization, the traditional construction method of all on-site pouring has gradually changed to a construction method in which part or most of the components are prefabricated in a factory and then transported to the site for installation. Compared with traditional construction methods, industrial production methods are the first What have been solved are the connection between the prefabricated components and the self-heaviness of the prefabricated components. In the process of bridge industrialization, the upper structure is earlier than the lower structure. The bridge industrialization mentioned at present mainly refers to the industrialization of the lower structure, that is, t...

AI Technical Summary

Problems solved by technology

At present, the connection form between multi-section prefabricated piers mainly adopts sleeve connection. This assembled connection method often requires pre-embedded steel connection sleeves in the prefabricated sections of the pier, and as the height of the pier increases, the number of pier sections also needs to increase. At the same time, the number of steel connection sleeves that need to be pre-embedded also increases accordingly, and the increase in the number of steel connection sleeves greatly increases the cost of manufacturing pier columns

On the other hand, the prefabricated assembly method of the pre-embedded steel connection sleeve has high requirements for construction accuracy and grouting quality. During the assembly construction process, there are requirements for accurate positioning and grouting between the components, and the grouting density in the sleeve is very high. Difficult to detect, which makes the sleeve connection method subject to certain restrictions in practical engineering applications
