ABSTRACT
The design is on the LiuPanShui in Guizhou Province, drainage pipe network engineering design includes a water supply and drainage system, a sewage drainage system and a stormwater drainage system. Design of the main contents and depth should be in accordance with the basic constructive procedures and relevant designed rules and procedures. Usually, the main designed content of water supply pipeline system includes: basic designed data (including the area of the design area, designed population and water quota) determination; The layout of Water supply pipeline system; Design flow calculation and hydraulic calculation of Water supply piping system. Sewage system is completely separate and drainage system. The pipe network design content of the sewage drainage system includs the division of the drainage area, layout of piping systems; population and sewage fixed according to the design, calculation of sewage design flow; hydraulic calculation of the sewers, the sewage hydraulic computation to determine the diameter, slope, flow rate and buried depth of the design parameters; draw the sewage pipeline plan and profile maps. Stormwater drainage system pipe network designing content includs division of the drainage area for rainwater sewers, fixing line, determing the outlet location; dividing designed tube segment, calculating each pipe segment design discharge; rain hydraulic Computation conduct rainwater pipe channels cut to divert force calculation, and determine the diameter, slope, and flow rate and burial depth design parameters; draw rainwater pipeline plan and longitudinal section diagram.
KEY WORDS: Drainage system, Piping layout, Design parameters, hydraulic
