Tenders Are Invited For Drainage Construction Works - Sealing Of The Border Grave In The Bitch Moor Moor

Drainage Construction Works - Sealing Of The Border Grave In The Bitch Moor Moor. Over A Length Of Around 800 Meters, The Trench Piping Consisting Of Plastic Pipes Dn600 And 9 Inspection Shafts Made Of Concrete Pipes Is To Be Expanded. At A Length Of Around 730 M, From North To Shaft No. 8, The Trench Profile On The Sole Of The Trench Is To Be Sealed With Clay. The Trench Is Located In The Middle Of A Drained Raised Bog And Can Only Be Reached Via Peat Paths With Very Limited Load -Bearing Capacity. The Construction Vehicles Have To Go To The Scene Only Via These Paths, And Load Clay At The Withdrawal Point In The West Of The Project Area And Transport Them For Use In The Grenzgrabentrasse. A Building Site Can Be Set Up On The Edge Of The Bog At The Beginning Of Road Section 2, The Specific Location Is Determined In Coordination With The Ag. All Roads, Turning, Encounter And Alternative Points Must Be Secured With Suitable Panels At The Election Of The Bidder. The Floor Pressures Created By The Vehicles And The Clay Transport Must Be Coordinated With The Load -Bearing Capacity Of The Chosen Trace Protection. Because Of The Limited Load -Bearing Capacity Of Hochmoortorf, Dredging Work Is Only Possible Using A Suitable Moor Drive Or The Use Of Excavator Mattresses. Before The Actual Sealing Work Begins, The Construction Site Must Be Separated From Two Trench Fillings From Adjacent Water -Filled Trench Sections So That No Water Runs Into The Construction. If This Is Created, A Water Posture Is Required Here To Remove The Bog Water Remaining In Between In The Border Trench Route And Prevent Moor Water From Penetrating During The Construction Period. The Border Grave Is Sealed In Sections From The South To North; The Excavator Moves In Front Of The Head On The Grenzgrabentrasse. The Wood Lying In The Route Can Be Used To Attach The Movement Area Of The Excavator And Is Then Temporarily Stored On The Border Grave Road On The Border Grave Road On The Edge Of The Grenzgrabentrasse On The Edge Of The Grenzgrabentrasse. The Plastic Tube, Which Is Located In The Border Trench, And The 7 Inspection Shafts Are Expanded. All Removed Plastic Pipes And Inspection Shafts Are Loaded By The Bidder, Transported And Disposed Of From The Area. After The Removal Of The Pipe, A Ditch Of 3 M Wide Is Created Up To The Former Trench Sole Of The Border Trench, The Excavation Is Applied Directly To The Clay Seal Of The Previously Sealed Section. A Clay Seal Is Inserted On The Exposed Former Trench Sole In A Thickness Of 1.2 M. In The Course Of The Dismantling Of The Road Protection, Hochmoortorf Is Taken From Peat Deposits And Installed Into The Grenzgrabentrasse To The Respective Target Height. The Peat Deposits Are Located On The Dutch Side Of The Grenzgrabentrasse. Finally, Four Peat Inlets With A Clay Core Are Over D
