Neither were we necessary 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 plates that are memorial the draw period. But we considered renovation regarding the connection look as created by S. Kerbedza to be our expert responsibility and our duty as Petersburgers as well. And we also did so, so when rehabilitation had been completed it became clear for the town management it was Blagoveschensky Bridge that it was not Lieutenant Schmidt Bridge any more. This is one way the connection received straight straight back its initial title.
The St. Petersburg World Club awarded Institute Stroyproekt an indication of Conformance for Blagoveschensky Bridge rehabilitation.
The exact same reward had been fond of Mostootryad 19 and Committee on State Control, Use and Protection of Historical and Cultural Heritage. However, in this specific instance the Committee merits are not very evident. On the basis of the Committee’s requirement the memorial dishes reading that the connection had been called after Lieutenant Schmidt, a hero for the revolution of 1905, and rebuilt in 1930s on the basis of the design by Peredery were preserved. We addressed to your Committee showing why these plates misinform residents and visitors regarding the city and asked for extra dishes become installed to say rehabilitation of 2006 – 2007. Nonetheless, a refusal was received by us to your demand. But we do hope that justice may be finally offered. Though Blagoveschensky Bridge comes back us towards the center of XIX century it’s a structure that is modern ere the essential interesting technical solutions have already been 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 protect historic first step toward wood piles. It became feasible because of the deck self-weight decrease and a design that is new wh ere the draw period deck is supported perhaps maybe not by piers but by fixed decks. Such structure permitted achieving main bearing regarding the draw piers and excluding eccentricity.
Guss asphalt had been utilized at Blagoveschensky Bridge; by that point it currently gained good reputation at the draw course of Alexander Nevsky Bridge, at Troitsky Bridge as well as the Ring path. We brought guss asphalt technology to Russian connection building training after it turned out introduced by ABZ-1 Asphalt concrete plant which was the very first plant inside our nation to perfect this technology that is german. Guss asphalt technology for connection building has resolved a long-lasting issue with all the connection floor at draw spans and plate that is orthotropic.
European countries is left out for the time being, why don’t we return to our topic that is favorite of reinforced tangible for intensive utilization of which we had been bitterly criticized on many occasions. Normally, Russian connection industry (as well as other spheres) lags far behind the tendencies that are worldwide. Advanced achievements are often introduced in some 10– to our country 15-year delay. Nevertheless, the problem with composite strengthened 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 look connection with the Western tall Speed Diameter in St. Petersburg has shown soundness of y our place.
The Turkish and Italian Consortium IC Iзtas– Astaldi have already been involved to create probably the most complicated Central Section associated with Western High Speed Diameter (WHSD). Certainly one of their requests that are first to exclude cast-in-situ concrete structures and only composite people. As previously mentioned by well-known French company Setec tpi, that is a consultant of y our colleges from Turkey and Italy, cast-in-situ concrete is recognized as traditional when you look at the present-day European countries and it is mostly utilized by European organizations into 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 materials that people first introduced about twenty years ago at our very own danger has become commonly found in European countries: composite reinforced tangible proved to be less costly, more desirable and sturdy.
In terms of strengthened concrete beams, unfortuitously numerous Russian areas nevertheless make use of them in connection construction. From our part we now have recommended GK Rosavtodor to change the look of standard strengthened tangible beams. Stroyproekt has discovered a standard and practical solution that enables managing drawbacks regarding the current beam designs without re-equipment of manufacturing flowers. Our concept was accepted definitely and we also wish that a standard that is new design are going to be developed and authorized.
The project of Western tall Speed Diameter is now a quintessence of y our expert experience.
Generally speaking, the WHSD is definitely a project that is innovative different standpoints. This is the very first expressway, that may connect the southern and north borders of St. Petersburg to your town centre. Besides, additionally it is the toll that is first associated with Northern Capital of Russia. Finally, the WHSD task includes a few design solutions that deserve an even more information consideration. Included in this, the bridge that is unique associated with WHSD Central Section which will form up St. Petersburg water Faзade, in specific: – a dual deck connection over the town top navigation channel, called as water Channel (the bridge is 734 m long; its main period is 168 m very long; the underclearance is 52 m); – A cable-stayed connection across Korabelny Fairway (the bridge is 620 m long; its main period is 320 m long; the underclearance is 35 m); – The extrados bridge across Petrovsky Channel (the connection is 580 m very very long; its main period is 220 m very very very long; the underclearance is 25 m).
The most important the main WHSD path runs via a corridor that is narrow compact commercial areas. Not enough free room ended up being the absolute most pronounced in the part from Stacheck Prospect to your Ekaterinhofka River (Construction phase II). To deal with these constraints our developers have proposed trusses that are double-deck this part as well as for many phase IV sections. Double deck trusses enable isolating traffic that is opposite towards the reduced and top deck correspondingly (supplying 4 lanes either in traffic way). Horizontally, the trusses are observed on a adjustable radius curve with superelevations and change areas, that will be extremely uncommon for dual deck structures. The longest period is 144 m.
The WHSD design includes various other solutions that aren’t therefore large-scale yet still quite interesting. Including the toll plaza during the exit ramp to Automobilnaya Street (phase we) may be taken which was built on two amounts as a result of exceptionally space-limited area. Aesthetically the WHSD path was developed in a uniform, recognisable and mode that is dynamic the arc-shaped illumination poles are incorporated utilizing the curved sound displays. 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, its impractical to provide the full summary of all innovations introduced by Stroyproekt or just interesting tasks inside the solitary article. Nonetheless, i do want to emphasize a few tasks that mirror our expert philosophy when you look at the way that is brightest. In 2003 we developed the design and dealing drawings for reconstruction for the connection throughout the Volga River in Kimry city of Tver area. For the very first time in Russia, strengthening for the current prestressed strengthened concrete field deck had been implemented by way of the cable-stayed system. To level the carriageway we now have utilised light and nanomodified concrete with bulk weight of 1.6 t/m2 and plastomagnetic balls in the place of crushed rock. It has permitted increasing the connection capacity as much as standard ukrainian mail order bride values and straightening the carriageway profile.
