- Abstract:
- Due to the different functions of different floors, there will be misplacement of beams and columns in high-rise buildings. Therefore, beam avoidance treatment is required when installing the drainage system. The solution is usually to install offset pipe in the project. However, this setting will greatly affect the drainage capacity of the riser. This paper compared the special installation method with the special ventilation and drainage system with anti-reflux H-pipe connection, and monitored the characteristic parameters such as pressure fluctuation, water seal loss and drainage system ventilation of each floor during the drainage process. The maximum drainage flow rate of the special ventilation and drainage system without offset pipe but with an anti-reflux H-pipe connection was 11.0 L/s. However, the drainage system with offset pipe was only 6.5 L/s, and the maximum drainage flow rate was 8.0 L/s when the anti-reflux H-pipe was installed above the offset pipe, indicating that the measure reduced the influence of the pressure fluctuation exerted by the offset joint and increased the water flow capacity of the riser.
