Problems and Solutions in the Design of Rainwater Pipe Networks

摘要

At present, there is more storm waterlogging in our urban, one of the main reasons is that there are many disadvantages in rainwater pipe network design, this paper in the pipe network design must be reasonable to determine the ground water runoff coefficient, The ground water time, reduction coefficient, catchment area and position and quantity of gully according to the measured data, and appropriately increasing the recurrence interval according to the actual in engineering, hydraulic calculation as much as possible to select data sets larger diameter, accurate calculation time of flow, to reduce the urban storm waterlogging fundamentally.
