راهنمای استاندارد برای طراحی، نصب و بهره‌برداری و نگهداری سیستم‌های زهکشی زیرزمینی شهری: سه استاندارد کامل: راهنمای استاندارد برای طراحی زهکشی زیرزمینی شهری ASCE/EWRI 12-13، راهنمای استاندارد برای نصب

In a single volume, Standards ANSI/ASCE/EWRI 12-13, 13-13, and 14-13 establish the guidelines for design, installation, and operation and maintenance of urban subsurface drainage systems. This Single-volume Set Of Three Standards Establishes Guidelines For Design, Installation, And Operation And Maintenance Of Urban Subsurface Drainage Systems. Ansi/asce/ewri 12-13 Provides Guidelines For The Design Of These Systems And Covers Site Analysis, System Configuration, Drain Envelopes, Hydraulics And Hydrology, Structural Considerations, And Materials. Ansi/asce/ewri 13-13 Focuses On Installation And Examines Site Investigation, Installation Procedures, And Inspection. Ansi/asce/ewri 14-13 Provides Guidelines For Operation And Maintenance (o&m) Of Urban Subsurface Drainage, Including O&m Plans, Safety, Water Quality, Inspection, Maintenance, And Rehabilitation. This New Edition Contains Major State-of-the-art Updates To Standard 12 Regarding The Hydraulics Of Different Types Of Drains, Including Drain Pipes, Aggregate Drains, Geotextile Drains, And Geonets And Geocomposite Drains. Throughout These Standards, References Have Been Added And Updated. Together, The Three Standards Offer Comprehensive Guidance For The Collection And Conveyance Of Subsurface Drainage Waters In Industrial, Commercial, Residential, And Recreational Areas, As Well As For Applications Such As Airports, Roads, And Other Transportation Systems. Engineers Working With Subsurface Drainage Systems, Along With The Owners Of Such Systems, Will Find These Updated Standards To Be A Valuable Resource. Prepared By The Urban Drainage Standards Committee Of The Standards Development Council Of The Environmental And Water Resources Institute Of Asce.
