The subject of this order is the execution of Contract III, which includes the following tasks:
Task 3 - “Development of the waters of Dłubnia course in the area of Botaniczna Street and Zawisza Czarnego Street”
The object of the task Landing of the Dłubnia course in the area of Botaniczna Street and Zawiszy Czarnego Street is a drain and overflow structure and a dam on the Dłubnia course. These structures are designed to produce retention of rainfall and melt waters in the natural sky — the valley of the Dłubnia river, at a length of about 150 m, located between Botanika Street and the road embankment on Zawisza Czarnego Street. The scope of the investment intended shall include in particular the following designed structures and works: − demolition of an existing concrete culvert with a light 1,2x1,5 m, − removal of trees and shrubs from the road embankment, − partial demolition of the road embankment (after the rail rail), restoration and adaptation to function as a head-on dam of the reservoir, − construction of a road surface on the crown of the dam, − a drain and overflow structure, with a reinforced concrete structure consisting of a tower with a floor height of h=3,54 m, a drain pipe with two lamps 0,8x0,8 m and outlet chamber. “Strengthening of the slopes and the bottom of the Dłubnia course in the area of Zawisza Czarny Street in Zielona Góra” which is part of the documentation. “Development of the waters of Dłubnia course in the area of Botaniczna Street and Zawisza Czarnego Street”:
Among other things, the work consists in strengthening the trough of the Dłubnia course above and below the planned drain and overflow structure and the dam on the Dłubnia course in the area of Zawisza Czarnego Street.
Task 4 - “Arrange the rain drains in Nowojędrzychowska and Makowa streets together with the construction of a park pond on Dłubnia course at Makowa Street in Zielona Góra”
The above task covers its scope:
-The opening ditch along Nowojędrzychowska Street on a section of 242m:
Decommissioning of the existing open ditch D3 along Nowojędrzychowska Street from the junction with Makowa Street on the 242m section and execution in this place፦ a rain channel with a diameter of DN600 - drainage thrust with drainage pipe in a filter shower. The designed rainwater channel should be connected to the existing rainwater drainage system kd600 in the area of the junction of Makowa-Novoydrzychowska Street through the designed concrete well DN1200. At the end of the canal, replace the existing brick chamber with the finished concrete well DN2000 and incorporate the existing KD1000 rain channel into it. The total length of the new channel is 242m and a longitudinal drop of 0.2 to 0.7%. The channel projects 9 DN1200 concrete wells and 1 concrete well DN2000 on the connection to the KD1000 bet channel. In addition, all tributaries which at the moment have their outlet in the open ditch it is the rain channel kd200 and the free-to-air channel ko150. Parallel to the rain canal at a distance of about 1.0m from its axis, drainage drainage from a fluted pipe with diameter DN160/145mm
-Execution of a bypass
For the cleaning of rainwater from solid suspensions and petroleum substances, a bypass on the rainwater channel kd600 at Makowa Street, directing rainfall water to a coalescent separator with nominal flow of 120dm3 /s and maximum 1200 dm3 /s with auto-closure and bypass storm integrated into the settler.
-Construction of a park pond
Scope of construction element:
construction of the canopy of the pond,
slabs with a depth of 1,1-2,1 m, with slopes of 1:1 ,5 inclination,
retaining wall in the area of the inlet into the pond, in the form of a reinforced concrete and stone wall fixed on a sealed steel wall,
Chubni trough at the bottom of the pond, with paving fixation,
piling structure with concrete overflow and closed drain hole,
Steel Working Bridge
walkways and railings on the banks of the pond, − repair and protection of existing reinforced concrete structures of the inlet and outlet of culverts in Dłubnia,
plantings of trees, shrubs and low vegetation in the park.
