Abstract:

Aiming at the problems of easily crossing with other processes, hard to control the size error of the acoustic board and the tight construction period during the installation and construction of the fully enclosed sound barrier acoustic board in railway, the installation and construction technology of acoustic board based on improved mounting trolley is put forward. Taking Guyong Bridge in Jinxing Railway as an engineering example, an improved acoustic board mounting trolley is designed to make the installation of small components for the fully enclosed sound barrier, inspection of steel arch frames and rectification acceptance work not restricted by the erection of single-line box girders. The construction technology for the installation of acoustic board on the fully enclosed sound barrier of the railway is studied, and the corresponding construction precautions are proposed. The installation and construction methods of fully enclosed sound barrier acoustic board have the obvious implementation effects in improving the construction accuracy and efficiency, and reducing the construction costs and cross operation risks, which can provide reference for the construction of similar projects.
