Work Detail

Pipeline Lifting And Relaying - Displacement Of Pipelines Technical Water, A To The Ii And Iii System Of 4 Bl. Out Of Machine Room. The Envisaged Activities For The Subject Of The Contract Are Related To The Implementation Of A Working Project On The Topic: Displacement Of Pipelines Technical Water Group A To Ii And Iii System Of 4 Block Outside The Machine Room. The Subject Of The Contract Covers Activities For Displacement Of The Technical Water Pipelines Of The Ii And Iii System Of 4 Energy Block Outside The Machine Room (Mh) In A New Reinforced Concrete Technological Tunnel With A Length Of 115M. The Pipelines Of Systems Ii And Iii (Pressure And Drainage) Are Interrupted Before Entering The Mh (On The North Facade), After Which It Will Be Surrounded By A New Route Of Steel Pipelines F273x6.3 Implied And Shy With A Length Of 490M. In A New Technological Tunnel And Are Included In The Existing Pipelines Of Systems Ii And Iii (Pressure And Breakfast) In An Existing Technological Tunnel On The Southern Facade Of The Ministry Of Health. A New Camera Is Being Built Next To The Northern Facade Of The Moh. It Also Performs Bypass Connections Between Iii Sliven With Iii. The Bypass Sections Are Mounted Two Pieces Of Steel Shut -Off Reinforcement Handles Of The Dn250 Of The Flanges. During The Displacement Of The Pipelines, Steel Pipelines Will Be Dismantled To F720 And Fittings To Dn 250 With Approximate Weight Up To 2000Kg. In The Seizures Of The Pipelines, Before Entering The Machine Room, Steel Caps (Silence) For Pipes F720-6Pcs, F530-6Pcs Will Be Delivered And Installed. And F 273-4Pcs. The New Camera On The South Side Of The Mh, Partially Affects An Existing Linear Drain. The Linear Drainage Is Interrupted At 1M. West Of The Wall Of The Camera, And In This Section It Is Not Restored After The Completion Of The Construction Works (Construction Works). In The Place Where The Linear Drainage Is Affected By The Technological Tunnel, It Is Dismantled And After The Construction Of The Construction Works Is Restored. Four Dn32 Diameter Drains Are Installed In The New Camera On All Four Pipelines. All Pipelines Provided For In The Project Are Joined Through Front Welding Joints. Relationships To Shut -Off Fittings Are Made On Flanges. Reinforced Concrete Shafts Are Planned To Access The Shut -Off Fittings. The Shafts Enter Through Metal Open Lids Mounted On The Roof Plate And Access To The Bottom Is Made By Vertical Steel Stairs. In The Part Of Construction And Constructive (Sc) Of The Project, Formwork And Reinforcement Plans Of The Tunnel And Shafts And Work Production Drawings Of The Necessary Supports For The Installation Of The Pipelines Are Given. Pipelines And Fittings Will Be Installed On 4Pcs Steel Sliding Supports And 16 Pcs. Steel Guide Supports. The Accession To The Existing Pipes Of Ii And Iii Consistent And Pressure Systems Is Through The Front Welds. Welding Is Carried Out According To A Pre -Developed And Approved Welding Plan. Welding Compound Control 100% Visual And 5% Radiographic. All New Pipe Sections Will Perform A Hydraulic Test Of Strength.
