New Technology and Application of Installation of Hinge Bolts for Radial Gates

In the installation process of the metal structure radial gate support hinge in hydropower stations, the installation accuracy of the support hinge bolts determines the later installation accuracy of the gate and plays a crucial role in the entire gate installation. However, the general installation process for hinge bolts involves measuring and controlling the installation of each bolt. Due to the large number of bolts and their spatial positions, the measurement and positioning are very complex, resulting in low accuracy of hinge installation in the later stage and affecting the quality of hinge installation. Through research and analysis of traditional installation methods, this paper proposes an integrated control scheme for bolt groups using an installation auxiliary device with simulated hinges. This approach simplifies conventional installation processes while enhancing construction quality and efficiency. The successful implementation experience of this process can provide reference for the installation of hydropower gates.
