Research on Hanging Basket Suspension Casting Technology in the Construction of Prestressed Continuous Box Girders for Highway Bridges
In order to study the process key points and application measures of hanging basket suspension pouring technology,based on the reconstruction and expansion project of the Dongying to Qingzhou Expressway of the Xiaoqinghe Extra Large Bridge,this paper focuses on analyzing key processes such as hanging basket design,hanging basket assembly,hanging basket preloading,hanging pouring construction,and prestressed tensioning,and proposes quality control measures(precautions).The results indicate that the hanging basket suspension pouring construction plan formulated for the prestressed continuous box girder of the project is reasonable and feasible,with good safety conditions throughout the construction process and excellent engineering quality.
