Construction-Site Supervision Services – Construction Supervision Kib, Tb 4.2, Lst And Sigeko Eü Untergraben Str. 2810 Km 10,530. T.016060034 Railway Overpass (Eü) Undercut In Hagen-Dahl Route 2810, Km 10.53 +0.00 The Structure Is Located On The Single-Track, Non-Electrified Route 2810 Hagen – Dieringhausen. The Railway Line Crosses The Untergraben Waterway In Hagen-Dahl At Km 10.53+0.00. The Untergraben Flood Ditch Is Privately Owned (Third-Party Property Belonging To Nagel), The Other Affected Areas (Railway System, Construction Roads And Be Areas) Are On Railway Property. The Eü Untergraben Can Be Reached From The Rehbecke Road Level Crossing (Route 2810, Km 10,610) Via The Railway Body/Tracks. The Rehbecke Street Branches Off From The B54 Federal Highway (Prioreier Straße) And First Crosses The Volme And Then The Railway Line. The Eü Is Located In The Wooded Bank Of The Volme Without Connection To The Road Network. The Railway Line Crosses The Flood Ditch With The Tributary To The Volme From North-East To South-West With A Crossing Angle Of Around 155 Gon. A Second, Dismantled Track Had A Crossing Angle Of 178 Gon. The Crossing Angle Between The Former Two Tracks Changes, So That The Structure Is Divided Into Two Sections. Currently Only The Eastern Track Is In Operation, The Second Track, Which Has Been Dismantled, But Has Become Overgrown In The Area Of ​​The Dismantled Track. Currently Only The Section From Hp Hagen-Oberhagen To Üst Hagen-Delstern Is Double-Tracked. The Single-Track (Operational Track) Railway Section Is Located In The Southwestern Area (Behind The Eü) At Approximately The Same Level As The Railing And Is Located Northeast Of The Ditch In A Cutting With A Transition To The Hengstenberg Tunnel. The Bridge Structure Is Located In The Valley Floor Of The Volme, Which Has Cut Deep Into The Rhenish Slate Mountains. The Railway Embankment In The Area Adjacent To The Structure Is Approx. 10.5 M Wide. The Untergraben Eü Is Located In The Curved Track With A Radius Of 307 M And Runs North Into The Hengstenbergweg Tunnel. The Elevation In The Building Area Is 125 Mm. The Existing Structure, Built In 1912, Has A Superstructure With Steel Beams In Concrete. The Heavyweight Abutments Are Made Of Quarry Stone Masonry And Have A Flat Foundation. The Renewal Of The Railway Overpass Is Necessary In Order To Be Able To Guarantee Economical And Safe Operational And Traffic Safety In The Long Term. The Existing Railway Overpass Including The Adjacent Retaining Walls Is To Be Replaced By A New Building And Is Designed For A Service Life Of 100 Years. Due To The Variant Investigation In The Preliminary Planning, A Different Type Of Construction Results For The New Building Compared To The Existing One. The New Structure Is A Full Frame Made Of Reinforced Concrete. From A Superstructure Perspective, No Changes To The Track Position Are Planned. A Narrow Track Closure Is Necessary As Part Of The Work On The Eü And The Superstructure Work For The Traffic System.
