Prior Information Notice For Construction Work For Water Projects – Converting A Bed Fall Into A Bed Slide In The Schildau Near Bornhausen

Prior Information Notice For Construction Work For Water Projects – Converting A Bed Fall Into A Bed Slide In The Schildau Near Bornhausen. As A Compensatory Measure For The Construction Of A New Flood Retention Basin East Of Bornhausen, The Creation Of Ecological Continuity Of The Schildau Is Determined By Converting A Bed Drop Into A Bed Slide. The Existing Bed Drop (Height Difference Approx. 0.85 M) Is To Be Converted Into A Rough Bed Slide With 64 Disturbing Stones (Large Lmb 60/300) In Order To Restore The Ecological Continuity Of The Water. The Planned Sole Slide Has A Length Of Approx. 41.0 M And A Longitudinal Inclination Of 1:30 And Then Flows Into A Secondary Bed With A Length Of 9.00 M And A Depth Of 0.45 M. The Total Length (Inlet Area + Sole Slide + Additional Bed) Of The System Is Approx. 60.0 M. The Embankment Width (Ok Embankment) Is On Average 8.0 M And Is A Guarantee To Ensure Ecological Continuity At Lower Water Levels, An Approximately 1.10 M Wide Low-Water Channel Will Be Created Within The Sohlgleite. In Advance Of The Construction Project, A Dewatering System Consisting Of Two Cofferdams (Dimensions Per Dam Approx. 6.0M X 1.0 M X 1.10M - L X W X H), As Well As A Water Diversion Consisting Of A Ditch + Piping (Dn 600, Length Approx. 90.0 M) Must Be Created. The Construction Project Includes Earthworks With A Volume Of Approx. 420.0 M³, As Well As Demolition Work With A Volume Of Approx. 40.0 M³. As Part Of The Hydraulic Engineering Work, The Bottom Slide Described Must Be Provided With A Revetment (Lmb 10/60 To 40/200) With A Volume Of Approx. 350.0 M³.
