Air Valve Chamber Construction
Construction Method of Air Valve Chamber for Ductile Iron Pipeline Air valves play a critical role in water transmission systems. They are typically installed at high points along the pipeline to release trapped air, thereby ensuring smooth and efficient flow. This section outlines the step-by-step construction procedure of an air valve chamber for a Ductile Iron (DI) pipeline, supported by site practices and illustrative references. 1. Installation of All-Socket Tee The first step involves the installation of an all-socket tee within the DI pipeline. A cut section of pipe is connected to the branch of the tee to facilitate the future installation of the air valve assembly. For proper execution of subsequent civil works, a minimum clearance of 3 meters should be maintained on both sides from the centerline of the tee. This space is essential for shuttering, reinforcement placement, and other formwork activities. After installation, the pipe invert level and alignment must be caref...
I really very glad for your comment.
