Design method and design system for roof rainwater drainage systems and drainage system
The invention provides a design method for roof rainwater drainage systems, which comprises the following steps of: calculating the volumetric flow rate of water flowing through a rainwater hopper; calculating the mass flow rate of an aerified water flow; calculating the pressure loss of each pipeline section based on the mass flow rate of the aerified water flow; calculating the values of negative pressures on a hanged pipe and a stand pipe at the junction point of the tail end of the hanged pipe and the top end of the stand pipe; judging whether the values of negative pressures on the hanged pipe and the stand pipe at the junction point satisfy the design requirements of a pipe system or not, if so, completing the design process; and otherwise, designing the value of each pipe diameter again, and then calculating again. Therefore, in the drainage system designed according to the design method for roof rainwater drainage systems provided by the invention, the pipes of the drainage system are thin and short in length, so that the application quantity and construction quantity of the pipes can be reduced, thereby reducing the cost of the whole drainage system. Meanwhile, the drainage system is additionally provided with an exhaust device, therefore, the hidden troubles such as roof rainwater ponding and leakage as well as manhole sweating can be avoided.
