Key Technology for Planning and Construction of Automated Production Lines in Large Bridge Factories

Abstract

<p>Prefabricated bridges are one of the key means to realize industrialized bridge construction. Tradi- tionally, bridge components are produced in temporary prefabricated girder yards serving a single specific project, which produce prefabricated components with limited use and low utilization rate. Therefore, the construction of permanent prefabricated production bases has gradually become the trend of the highway bridge industry. This paper discusses the planning method and construction technology of permanent precast production plants for different concrete members of highway bridges. The construction method of bridge precast plants in terms of production line selection, equipment selection and application is introduced. Eventually, the key technologies for the auto- mated production lines and construction of large bridge precast factories are systematically estab- lished to provide reference for the construction of highway bridge precast factories.</p>
