- Abstract:
- Taking the utility tunnel project in the south section of Pingtan Western Avenue in Fujian Province as an example, the design of sewage pipe and important nodes in urban utility tunnel was discussed. Considering the installation characteristics of the sewage pipe and the danger of wastewater leakage in the tunnel, the pipe with advantages of anticorrosion, pressure, good sealing performance and high strength should be adopted as the gravity flow sewage pipe in the tunnel. Manholes directly to the ground and vent holes were set up in sewage branch pipe access and slope change point. In order to ensure the pipeline clearing equipment working well, the vent holes were introduced to the 50 cm above the greening belt outside the tunnel, the distance between the manholes was not more than 120 m, and the diameter was not less than 1 000 mm. For the feed port transfer floor, the net height should be no less than 2.5 meters to facilitate the installation of the electric lifting device to transport the material. If the transfer layer was shared between the composite and electric compartments, the fire partition area was separated by topgrade antifire rolling curt and A class fireproof door in the transfer floor.
