Tenders Are Invited For Construction Of An Internal Road On The Skalne Estate In Dalki

The Planned Investment Includes The Construction Of Three Sections Of Housing Estate Roads Within The Skalne Estate In Dalki In The Commune Of Gniezno. Section I Is An Internal Road With A Total Length Of 254.5 M, Section Ii Is A Municipal Public Road With A Total Length Of 164.5 M, Section Iii Is A Municipal Public Road With A Total Length Of 109.7 M. The Basic Width Is 6.0 M. The Roadway Is Limited On Both Sides By A 12X25x100 Embedded Resistor. Behind The Retaining Wall, Two-Sided Ground Shoulders Hardened With Broken Aggregate With A Width Of 0.75 M Were Designed. Changes In The Transverse Inclination Of The Roadway And Its Width Along With Their Location Have Been Marked On The Land Development Plan (Fig. 2). At Km 0+130.0 To Km 0+160.0 (Section I), Due To The Proximity Of The Steep Embankment Of The Existing Water Reservoir, Retaining Walls Made Of Ready-Made L-Type Prefabricated Elements Were Designed At The Border With Plot No. 40/42 - Reinforced Elements With Dimensions Of 150X105x12 Placed On Made Of Lean Concrete C6/9 Gr. 15Cm. Other Details Of The Location Of The Route In The Plan In Accordance With Point 3 Of The Description To The Land Development Project. Road Drainage Is Carried Out In Several Variants. The Road Surface Was Designed With Eko Cubes, Which Is A Partially Absorbent Surface. Due To The Need To Limit The Amount Of Water Discharged Into The Ground, Which Does Not Show The Appropriate Absorptive Properties, The Designed Roadway Has An Inclination Towards The Designed Shoulder Of The Reinforced Road And The Adjacent Green Areas Of The Roadway. Additionally, The Following Were Designed: - On Section I - 2 Wells - With A Diameter Of St01 = 1.0 M At Km0+150.0 And St02 = 1.5 M At Km 0+163.0 (Overflow Well). Wells On All Sections Should Be Made As Tight Concrete Tanks H=3.0 M With A Relief Ring And A D400 Class Inspection Hatch. Rainwater Collected In Them Is Not Discharged Into The Ground Due To The High Level Of Groundwater And Impermeable Native Soils. They Must Be Emptied When They Are Full. At Km 0+135.0, A Concrete Inlet Wp1 Chamber With A Diameter Of 0.5 M, H = 1.5 M Was Designed, Together With A Relief Ring And A Cast Iron Grating, Class D400. The Manholes And The Inlet Should Be Connected With A Ppsn8 Dn300 Full Pipe. - On Section I - 2 Wells - With A Diameter Of St01 = 1.0M At Km 0+150.0 And St02 = 1.5M At Km0+163.0 (Overflow Well). The Wells Should Be Made As Tight Concrete Tanks H=3.0 M With A Relief Ring And A D400 Class Inspection Hatch. At Km 0+135.0, A Concrete Inlet Wp1 With A Diameter Of 0.5 M, H=1.5 M, With A Relief Ring And A Cast Iron Grating, Class D400, Was Designed. The Wells And The Inlet Should Be Connected With A Solid Pp Sn8 Dn300 Pipe. In Section I, An Inlet Wp2 (Km 0+205.0) Was Also Designed, Connected By A Pp Sn8 Dn160 Gully To The Inlet Wp3 At Km 0+210.0. The Wp3 Inlet Was Connected To The Existing Inlet Chamber Marked As Wp4 At Km 0+240.0 With The Ppsn8 Dn200 Side Drain. The Wp4 Inlet Chamber Is Planned For Replacement Along With The Shift In The Axis Of The Designed Road. On The Section From The Wp2 Manhole, A 3-Row In-Street Sewage Was Designed To The End Of Section I, Made Of Concrete Cubes, Thickness 8Cm. - On Section Ii At Km 0+009, On The Left Side, A Watertight Chamber With A Diameter Of St03 = 1.2 M Was Designed Along With An Inlet Wp5 Connected To The Chamber By A Pp Sn8 Dn160 Drain - On Section Iii At Km 0+025.0 And At Km 0+080, 0, Tight Chambers With A Diameter Of 1.2 M Were Designed With Inlets Wp6 And Wp7. On The Curve Connecting Section Iii With The Existing Roadway With An Asphalt Surface, A 2-Row Curb Gutter Made Of Concrete Cubes Was Designed In The Direction Of The Inlet Wp6. Details Of The Design Are Included In Pt+Sst.
