Design and Research on Sunken Road Drainage System
This article mainly explores the design points of sunken road drainage systems.In the design,the design flow of rainwater in the sinking section shall be calculated first according to the runoff coefficient,design rainstorm intensity and other parameters.At the same time,combining with on-site investigation to de-termine the type of sunken road section,for two or more continuous sunken road sections,connecting pipelines can be arranged between adjacent drainage points,and then a pump room can be built at the low-est drainage point for unified drainage,which helps to reduce the project scale and control project costs.From the application example of sunken road drainage system design,the rainwater design flow rate of the road is 1 308.6 m3/h,and the pump room design flow rate is 1.2 times the rainwater design flow rate,which is 1 570.3 m3/h.Install two submersible pumps with a rated flow rate of 800 m3/h in the pump room,which can meet the drainage needs.
