Tenders Are Invited For Construction Work – Expansion Of The S11/S-Bahn Main Line In Cologne - Pile Test Load Concept For Cologne Main Station

Construction Work – Expansion Of The S11/S-Bahn Main Line In Cologne - Pile Test Load Concept For Cologne Main Station. The Project “Expansion S11 Core Package Tm 7 – Cologne Main Station.” Is Part Of The Project To Expand The S11/S-Bahn Main Line In Cologne. Measures Are Planned To Increase The Capacity Of The S-Bahn Main Line. This Includes The Creation Of Additional S-Bahn Tracks Including Additional Platform Edges In Cologne Main Station And Cologne Messe/Deutz As Well As The Optimization Of The Control And Safety Technology In Order To Achieve A Reduction In Train Headway Times From The Previous 3.3 Minutes To A New 2.5 Minutes. The S11 Expansion Project Includes, Among Other Things, The Following Sub-Measure Mentioned Here In The Area Of ​​Db Infrago Ag: - Tm 7: Expansion Of The Cologne Main Station By Two S-Bahn Platform Edges On The North Side (New Central Platform On Tracks 12 And 13 Including Track Connections). In Connection With The Expansion Of The S11 At Cologne Central Station, Supports For The Route Are To Be Founded On Bored Piles In Accordance With Din En 1536, Which Are To Be Placed In The Sediments Of The Rhine Terrace. Due To A Strict Limitation Of The Pile Head Settlement To A Dimension Of 10 Mm Under Service Load, The Large Bored Piles, Which Are Predominantly Axially Stressed, Should Be Manufactured With Shell And Base Grouting. A Special Feature In The Planning And Execution Of Deep Foundations Are Structures Located In The Subsoil (E.G. Tunnels). Through Investigations As Part Of Pile Test Loads On Three Separately Manufactured Test Piles (“Test Load Piles” In The Sense Of Din En 1536), The Expected Load-Bearing And Deformation Behavior Of The Planned Structural Piles Under Static Loading In Both The Vertical And Horizontal Directions Is To Be Determined. The Test Piles Will Not Later Be Used As Structural Piles.
