Work Detail

Engineering Design Services For The Construction Of Civil Engineering Works – Ing.-Leistung Lp 1-4, Optional Lp 5-9. The Subject Of The Order Is The Planning Of Engineering Structures, Structural Planning And Technical Equipment As Part Of The Construction Of A Retention Soil Filter (Rbf) Below The Sku Castrop-Rauxel Holthauser Straße And A New Computing System At The Sku Cas-Holthauser Straße. The Planned Retention Soil Filter “Rbf Cas-Holthauser Straße” Is Located On The Left Side Of The Landwehrbach Between Km 3.9 And Km 4.3. The Planned Retention Soil Filter Is Downstream From The Sku Cas-Holthauser Straße, Which Is In The Overall Catchment Area Of ​​The Sku Her-Langforthstraße. The Current Draft Envisages Extending The Diversion Channel Parallel To The Landwehrbach By Around 130 M To Feed The Planned Rbf. The Mixed Water Flows To The Rbf At The End Of The Inlet Channel Via A 90 M Long Inlet Threshold With A Height Of 51.60 M Above Sea Level. According To The Explanatory Report, The Retention Soil Filter Is Divided Into Two Sections, Each With 2,520 M² Of Filter Area. The Filter Overflow Is At The End Of The Rbf. After The Rbf Is Completely Filled, The Water Flows Over A 90 M Long Threshold Into The Filter Drain Channel And Is Then Fed Into The Landwehrbach. The Rbf Cas-Holthauser Straße Retention Floor Filter Is Operated In Full Flow. This Means That The Inflow To The Rbf Is Not Limited. The 1-Year Rated Inflow Is Qzu,Rbf = 11,969 L/S. According To The Current Planning Status, No Natural Free-Slope Drainage Can Be Realized From The Retention Soil Filter To The Receiving Water. It Is Therefore Planned To Raise The Rbf Filtrate (100.8 L/S) Via A Pumping Station. In Addition, The Installation Of A New Computing System At The Sku Cas-Holthauser Straße Is Planned. An Existing “Central Virtual Process Control System” (Vpls) Is Already Implemented In The Cas-Holthauser Straße Sku. The Computing System Should Be Integrated Here.
