An auxiliary device for bridge support installation and a bridge support installation method

Abstract

The application provides an auxiliary device for bridge support installation and a bridge support installation method, wherein the installation method comprises the following steps: constructing the relationship between the reaction force deviation and the vertical displacement adjustment amount of the bridge support based on the reaction force influence matrix; placing the bridge support to be installed after arranging the auxiliary device at the installation position of the top of the pier; detecting and obtaining the actual reaction force value of each bridge support after erecting the main beam; combining the deviation between the actual reaction force value and the design reaction force value, and calculating the corresponding elevation adjustment amount of each bridge support through the relationship between the reaction force deviation and the vertical displacement adjustment amount; jacking up the beam body to form an adjustment space between the beam body and the bridge support, and adjusting the elevation of the support; fixing the bridge support and taking out the auxiliary device after the adjustment is completed, and pouring to form the support cushion stone structure; after the strength of the cushion stone structure meets the standard, the weight of the beam body is transferred to the bridge support, and the installation is completed. By using the installation method provided by the application, the installation precision and stability of the bridge support can be improved.
