Neither were we expected to restore a historic appearance of the Lieutenant Schmidt Bridge. Committee on State Control, utilize and Protection of Historical and Cultural Heritage asked for and then protect pavilions and memorial dishes on the draw period. But we considered renovation regarding the connection look as created by S. Kerbedza to be our expert responsibility and our responsibility as Petersburgers as well. And we also did therefore, so when rehabilitation ended up being finished it became clear for the city management it was maybe not Lieutenant Schmidt Bridge more, it absolutely was Blagoveschensky Bridge. This is one way the connection received right straight back its initial title.
The reward that is same directed at Mostootryad 19 and Committee on State Control, utilize and Protection of Historical and Cultural Heritage. Nonetheless, in this case that is particular Committee merits are not too obvious. In line with the Committee’s requirement the memorial dishes reading that the connection had been called after Lieutenant Schmidt, a hero regarding the revolution of 1905, and rebuilt in 1930s in line with the design by Peredery have now been preserved. We addressed towards the Committee showing why these plates misinform residents and visitors of this populous town and asked for extra dishes become set up to say rehabilitation of 2006 – 2007. But, we received a refusal to your demand. But we do hope that justice may be finally offered. Though Blagoveschensky Bridge comes back us into the center of XIX century its a structure that is modern ere the absolute most interesting technical solutions are realised. The connection became one . 5 times wider (from 24 to 36 m wide) and had been redesigned for nowadays lots, but in the time that is same been able to preserve historic first step toward wood heaps. It became feasible because of the deck self-weight decrease and a brand new design solution wh ere the draw period deck is supported perhaps not by piers but by fixed decks. Such structure permitted attaining main bearing regarding the draw piers and excluding eccentricity.
Guss asphalt had been utilized at Blagoveschensky Bridge; latin mail order bride by the period it currently gained good reputation at the draw period of Alexander Nevsky Bridge, at Troitsky Bridge as well as the Ring Road. We brought guss asphalt technology to Russian bridge building training after it turned out introduced by ABZ-1 Asphalt concrete plant that has been the very first plant within our nation to perfect this technology that is german. Guss asphalt technology for connection building has resolved a long-lasting issue using the bridge flooring at draw spans and orthotropic dish.
European countries is put aside for the time being, let’s go back to our topic that is favorite of reinforced concrete for intensive utilization of which we had been bitterly criticized on many occasions. Normally, Russian connection industry (and even other spheres) lags far behind the global tendencies. Advanced achievements are often introduced in our nation with a few 10 – 15-year delay. Nonetheless, the specific situation with composite reinforced concrete has progressed an additional means. They started changing to composite concrete when we first applied composite concrete, cast-in-situ concrete was still very popular in the West and only at the turn of the century. Furthermore, the style connection with the Western High Speed Diameter in St. Petersburg has shown soundness of our place.
The Turkish and Italian Consortium IC Iзtas– Astaldi have now been involved to create probably the most complicated Central Section associated with Western High Speed Diameter (WHSD). Certainly one of their very first needs ended up being to exclude cast-in-situ concrete structures in support of composite ones. As previously mentioned by well-known company that is french tpi, that will be a consultant of y our universities from Turkey and Italy, cast-in-situ concrete is recognized as antique within the present-day Europe and it is mostly utilized by European organizations when you look at the under developed countries wh ere there are not any qualified steelwork manufacturers.
Therefore, we got convinced of who had been actually appropriate for the reason that long-standing ideological dispute. The product that people first introduced about twenty years ago at our risk that is own is commonly found in European countries: composite reinforced tangible proved to be less costly, more desirable and sturdy.
In terms of strengthened beams that are concrete unfortuitously numerous Russian areas still make use of them in connection construction. From our part we now have recommended GK Rosavtodor to change the look of standard strengthened beams that are concrete. Stroyproekt has discovered a typical and practical solution that enables handling drawbacks for the current beam designs without re-equipment of manufacturing flowers. Our concept happens to be accepted definitely and now we hope that a brand new standard beam design will likely to be developed and authorized.
As a whole, the WHSD is a project that is innovative different standpoints. It will be the first expressway, that may link the southern and north borders of St. Petersburg to your city centre. Besides, it’s also the very first toll motorway associated with the Northern Capital of Russia. Finally, the WHSD task includes a few design solutions that deserve a far more information consideration. Included in this, the unique connection structures associated with the WHSD Central Section which will form up St. Petersburg water Faзade, in specific: – a dual deck connection throughout the town top navigation channel, known as as water Channel (the bridge is 734 m very very long; its main period is 168 m very very long; the underclearance is 52 m); – A cable-stayed bridge across Korabelny Fairway (the bridge is 620 m long; its main period is 320 m long; the underclearance is 35 m); – The extrados connection across Petrovsky Channel (the connection is 580 m very very very long; its main span is 220 m very very long; the underclearance is 25 m).
The main the main WHSD path runs by way of a slim corridor across compact commercial areas. Not enough free area ended up being probably the most pronounced in the area from Stacheck Prospect into the Ekaterinhofka River (Construction phase II). To handle these constraints our developers have proposed double-deck trusses for this area and in addition for many phase IV sections. Double deck trusses enable isolating traffic that is opposite to your reduced and top deck correspondingly (supplying 4 lanes in a choice of traffic way). Horizontally, the trusses are observed for a adjustable curve that is radius superelevations and change zones, that is really uncommon for dual deck structures. The longest period is 144 m.
The WHSD design includes various other solutions that are not therefore large-scale yet still quite interesting. Including the cost plaza at the exit ramp to Automobilnaya Street (phase we) may be taken that has been built on two levels as a result of excessively space-limited area. Aesthetically the WHSD path is developed in a uniform, recognisable and mode that is dynamic the arc-shaped illumination poles are incorporated utilizing the curved sound screens. The WHSD is perceived not just as a long-distance motorway but as a continuous engineering and architectural complex for this reason.
“Philosophy” for action needless to say, it’s impractical to provide a complete summary of all innovations introduced by Stroyproekt or just interesting tasks in the solitary article. However, i must emphasize a few jobs that mirror our expert philosophy when you look at the way that is brightest. In 2003 we developed the working and design drawings for reconstruction regarding the bridge throughout the Volga River in Kimry city of Tver area. When it comes to very first time in Russia, strengthening associated with the current prestressed strengthened tangible package deck ended up being implemented in the form of the cable-stayed system. To amount the carriageway we now have utilised light and nanomodified concrete with bulk weight of 1.6 t/m2 and plastomagnetic balls rather than crushed rock. It has permitted enhancing the connection ability as much as values that are standard straightening the carriageway profile.
