Tenders Are Invited For Canal Construction – Construction Project: Renovation And Renewal Of The Main Collector East

Canal Construction – Construction Project: Renovation And Renewal Of The Main Collector East. The Main East Collector Will Be Repaired Over A Length Of 1067 M Using A Trenchless Method Using Grp Pipes, Starting At The Rü27 Storm Overflow Basin. The Shafts In This Area Are Being Replaced. The Old Shafts For The Salzbach And The Main Collector Will Be Dammed Except For The Entrance To The Salzbach. Some Shafts Will Be Dismantled To Make Room For New Shafts. Instead Of The Grinding Track Crossing, Which Will Be Dammed At The End Of The Measure, A New Track Crossing Is To Be Created At Right Angles To The Tracks With A Length Of Approx. 127 M In Dn 1600 Tunneling. From The New Crossing At Shaft 44927, The Route Is Led Over A Curved Drive 352 M Parallel To The Tracks To Shaft 42225 And There Connected To The Existing Dn 1500. A Kilometer Measurement Will Be Laid Along The Newly Planned Route Starting At Shaft 42225. All Station Information Refers To This Planning Kilometering. The Measure Includes: - A Total Of 13 New Shafts In High-Performance Concrete - 2 Canal Tunneling Stb Dn 1600, 127 M And 352 M Microtunneling With Flushing Conveyance And Compressed Air Cushion - 1067 M Grp Renovation Of The Main Collector - Grp Renovation Of The Northern (159 M) And Southern Track Crossing (158 M) To Carry Out The Measure, Tracks Must Be Dismantled And Partially Re-Laid, To Build Construction Roads, Some Of Which Will Be Converted Into Service Roads, To Demolish Buildings And To Dismantle Parts Of Buildings During Construction. Since The Construction Pits Have To Be Built Close To The Tracks And Because There Is Groundwater, A Shoring Made Of Overlapping Bored Piles Is Planned. Detailed Information About The Construction Project Can Be Found In The Explanatory Report. Long Distances Have To Be Bridged To Procure Electricity And Water, Especially In The Area Of ​​The Starting Pit. In Some Cases There Are Old Water Pipes From Deutsche Bahn Ag That Can Be Used.
