Abstract
A super drainage system and a method for flood control comprise an open channel, a reinforced concrete conduit (RCC) inside the open channel. The RCC has a bottom slab supported on a riverbed, a bank-side wall for retaining bank soils, and a top slab elevated above a predetermined level. The RCC supports a road below the top of river banks for traffic traveling along the river banks during normal weather conditions. The traffic is either on the top slab or on the bottom slab. During extreme weather conditions, traffic is evacuated from the super drainage system and the entire space is available for water conveyance.
Claims22
A drainage system configured for controlling flood during extreme weathers and offering a road for traffic during normal weathers, said system comprising:
- a) an open channel having a first bank, a second bank and a riverbed;
- b) a reinforced concrete conduit (RCC), said RCC has a bottom slab supported on said riverbed, a first wall for retaining said first bank, a top slab elevated above a predetermined level and a second wall, and said RCC further comprising a number of RCC segments, each of said RCC segments having a male end and a female end;
- wherein said RCC supports said road below the top of said first bank, and said traffic travels on said road along said first bank during normal weathers.
(canceled)
A method for alleviating traffic congestion in a metropolitan area comprising serving traffic on a road inside a drainage system during normal weathers, said drainage system comprising:
- an open channel having a first bank, a second bank and a riverbed, a reinforced concrete conduit (RCC) inside said open channel, said RCC further comprising a number of RCC segments, each having a male end and a female end;
- wherein said road is 2-8 m below the top of said first bank and supported by said RCC along said first bank, and said RCC has a bottom slab supported on said riverbed, a first wall retaining said first bank, a top slab elevated above a predetermined level and a second wall.
(canceled)
A method for establishing a drainage system configured for controlling flood during extreme weathers and offering a road for traffic during normal weathers, said method comprising:
- a) inserting a male end of a reinforced concrete conduit (RCC) segment into a female end of an adjacent RCC segment repeatedly and forming a RCC with a number of RCC segments inside an open channel, said RCC has a bottom slab supported on a riverbed of said open channel, a first wall retaining a first bank of said open channel, a top slab elevated above a predetermined level and a second wall;
- wherein said RCC supports said road below the top of said first bank, said traffic travels on said road along said first bank during normal weathers.
