TECHNICAL DATA: In the route of the displacement of State Road D 507 sections of Krapinske Toplice – Čret as well as connecting roads of drains that are intended for reconstruction there are installations of water supply pipelines that remain inaccessible or damage to the intended procedures. The project foresees: - the existing water supply pipeline PVC DN 140 replaces with PVC pipe d 160 and protection protective pipe d 250, and the length of the operation is 28 m; - the existing water supply pipeline PVC DN 140 is replaced by PE pipes d 160 and the length of the operation is 280 m, - the existing water supply pipeline AC DN 100 is replaced by PE pipes d 110 and the length of the procedure is 27 m; - The existing water supply pipeline AC DN 100 is replaced by PE pipes d 110 and the length of the procedure is 255 m.
TECHNICAL DATA: The existing warm-water boiler room of the stadium "Maksimir capacity » 3.4 MW (90/70oC) does not meet the needs of new consumers and is required to reconstruct. New boilers will be installed in the space of the existing boiler room 110/70 oC (2 x 3 MW and 1 x 1.2MW), circulation pumps, bus, expansion and softening devices and collector. The total power of the new boiler room will be 7.2 MW, which meets the total heat load of the stadium "Maksimir". Although the boiler room is gas on all boilers, combined burners (light fuel oil - natural gas) are installed. Each boiler is connected to its own chimney and ends at a height of 33 m. The boiler room ventilation is natural. Regular checks, inspections, controls with proper use, controls and periodic maintenance of equipment is approximately 20 years.
TECHNICAL DATA: As part of the construction of the central wastewater treatment plant of the city of Zagreb, the landscaping and partial closure of the Main WasteWater Supply Channel of the city of Zagreb on the left bank of the Sava is also foreseen. To this end, the dodge of the existing Æ1000 mm pipeline has been projected. The transition over the future GOK is intended to be lifted into the power structure. The selected solution met the following conditions: - allow access to the water supply pipeline along the entire length for the need for possible procedures (repairs), - provide for all necessary pipeline insurance, - anticipate venting at the highest level Point - provide for thermal insulation according to the elaboration and freezing/heating of pipelines, - at the lowest points before and after the bridge provide shut-off chambers with discharges for sectional flaps. At the intersection with the railway track, the pipeline is protected by a steel pipe Æ 1200 mm. As it is a local industrial track, the protective pipe can be installed by cross. Securing the protective pipe will be performed with a concrete lining (MB 20) of a minimum thickness of 30 cm. Horizontal fractures on both sides of the GOK are designed for concrete strongholds. The project includes cathode protection, grounding and lightning defense. The total length of the mixed pipeline is 170 m.
