Garantujem da bi sve navedene stanice bile pune putnika,samo pogledajte masu koja živi na Vidikovcu,Bežaniji pa zar bi ti ljudi propustili priliku da do centra stignu za 15 ak min.? za razliku od sat vremena truckanja u autobusu pećnici do centra isto važi za Železnik,dok bi ljudima sa Dedinja centar bio na 5 min. :kafa: a evo i grube procene stanica Vidikovac bi koštala oko 15. mil$ kao i Dedinje zbog dubljih stanica,dok bi stanica Merkur Bežanija bila jeftinija jer je tu plići tunel,procena je otprilike kao nova stanica u ST.Petersburgu,gde su posebnom mašinom bušili od površine ka ranije izgrađenom dubokom tunelu,pominjali smo to u ranijim postovima,najeftinija bi bila stanica Airport C koja bi bila otvorena dozidana sa bočnih strana pruge.
tehnički Herrenknecht izrađuje i taj tip mini krtica pod štitom za probijanje pod uglom,jedna takva stanica se upravo radi u ST.Petersburgu, a kod Ceraka olakšava pristup potencijalnoj stanici tj.ulaz u tunel je blizu tog mesta.. roll
Evo nađoh tu stanicu kao primer,ako se radi samo jedna duboka stanica
evo sve lepo objašnjeno wink
St. Petersburg is the most northern megacity in the world and its metro system is one of the deepest in the world. The Station Obwodny canal is located on line 5 at a depth of 60 meters. For a long time it was not put into operation, since the access shafts from the surface were not yet built. The major challenge during mechanized tunneling of the 105 meter long escalator shaft was the gradient of 30°.
The solution was a Herrenknecht EPB Shield with a diameter of 10.69 meters which started with a special launch construction – developed and produced by Maschinen- und Stahlbau Dresden. The TBM was kept on its path during tunnelling with an innovative system of lifting cables and hydraulic cylinders in accordance with the parameters of the VMT guidance system. Two rail-bound wagons, drawn by winches, provided for the removal of the soil material. They also transported the lining segments below ground, which were produced in formwork made by Herrenknecht Formwork GmbH. Tunnelling went smoothly with the innovative machine made in Schwanau in the hands of the OAO Metrostroy specialists, achieving performances of up to 4 meters a day. The last lining segments could be installed in time for Christmas 2009 after only 12 weeks of tunnelling.
Ovim htedoh da kažem da postoje tehnička rešenja koja su drugi gradovi primenili,za gradnju jedne ili nekoliko dodatnih stanica na većim dubinama Posle samo 12 nedelja dobija se nova stanica,eto ovima iz grada da porazmisle jer su ovo brza rešenja
