Neither were we needed to restore a look that is historical of Lieutenant Schmidt Bridge. Committee on State Control, Use and Protection of Historical and Cultural Heritage asked for and then protect pavilions and plates that are memorial the draw span. But we considered renovation associated with connection look as created by S. Kerbedza to be our responsibility that is professional and duty as Petersburgers as well. So we did so, so when rehabilitation ended up being finished it became clear for the town management it was maybe not Lieutenant Schmidt Bridge anymore, it had been Blagoveschensky Bridge. This is one way the connection received right straight straight back its initial name.
The St. Petersburg World Club awarded Institute Stroyproekt an indication of Conformance for Blagoveschensky Bridge rehabilitation.
The reward that is same fond of Mostootryad 19 and Committee on State Control, utilize and Protection of Historical and Cultural Heritage. Nonetheless, in this specific instance the Committee merits are not very obvious. In line with the Committee’s requirement the memorial dishes reading that the connection had been known as after Lieutenant Schmidt, a hero regarding the revolution of 1905, and rebuilt in 1930s in line with the design by Peredery happen preserved. We addressed towards the Committee showing why these plates misinform residents and visitors associated with populous town and asked for extra plates become set up to say rehabilitation of 2006 – 2007. Nevertheless, we received a refusal to your demand. But we do hope that justice may be finally offered. Though Blagoveschensky Bridge returns us to your center of XIX century it really is a contemporary framework wh ere the absolute most 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 during the time that is same were able to protect historic foundation of wooden heaps. It became feasible because of the deck self-weight decrease and a design that is new wh ere the draw period deck is supported maybe maybe maybe not by piers but by fixed decks. Such structure allowed attaining main bearing regarding the draw piers and eccentricity that is excluding.
Guss asphalt had been utilized at Blagoveschensky Bridge; by the period 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 that has been the very first plant inside our country to understand this German technology. Guss asphalt technology for connection building has resolved a lasting issue because of the connection flooring at draw spans and plate that is orthotropic.
Europe is put aside 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 bridge industry (as well as other spheres) lags far behind the tendencies that are worldwide. Advanced achievements are often introduced in our nation with a few 10 – 15-year delay. But, the problem with composite strengthened concrete has progressed an additional means. As soon as we first used composite concrete, cast-in-situ concrete ended up being nevertheless highly popular within the western and just during the latin dating sites turn associated with century they began changing to composite concrete. Furthermore, the look connection with the Western tall Speed Diameter in St. Petersburg has shown soundness of our place.
The Turkish and Italian Consortium IC Iзtas– Astaldi have now been engaged to construct probably the most complicated Central Section associated with the Western High Speed Diameter (WHSD). Certainly one of their very first demands ended up being to exclude cast-in-situ concrete structures and only composite people. As previously mentioned by well-known company that is french tpi, that is a consultant of our universities from Turkey and Italy, cast-in-situ concrete is known as traditional within the present-day European countries and it is mostly employed by European organizations in 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 utilized in European countries: composite reinforced tangible proved to be less costly, considerably better and sturdy.
In terms of strengthened tangible beams, regrettably numerous Russian areas nevertheless utilize 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 solution that is workable enables handling drawbacks for the current beam designs without re-equipment of manufacturing flowers. Our concept happens to be accepted absolutely and we wish that a brand new standard beam design should be developed and approved.
The task of Western tall Speed Diameter is actually a quintessence of our expert experience.
Generally speaking, the WHSD is a project that is innovative different standpoints. It’s the expressway that is first that will link the southern and north borders of St. Petersburg to the town centre. Besides, additionally, it is the very first cost motorway for the Northern Capital of Russia. Finally, the WHSD task includes a few design solutions that deserve a far more information consideration. One of them, the unique connection structures regarding 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 very 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 bridge is 580 m very long; its main period is 220 m very very long; the underclearance is 25 m).
The main an element of the WHSD route runs through a corridor that is narrow compact commercial areas. Not enough free space ended up being probably the most pronounced in the part from Stacheck Prospect into the Ekaterinhofka River (Construction phase II). To deal with these constraints our developers have proposed double-deck trusses for this area as well as for a few phase IV sections. Double deck trusses enable splitting traffic that is opposite into the reduced and top deck correspondingly (supplying 4 lanes in either traffic way). Horizontally, the trusses can be found for a variable curve that is radius superelevations and change areas, which can be really unusual for dual deck structures. The longest period is 144 m.
The WHSD design includes various other solutions that are not therefore large-scale but nonetheless quite interesting. Including the cost plaza in the exit ramp to Automobilnaya Street (phase we) is 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 because of the curved noise 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, it really is impractical to provide a complete breakdown of all innovations introduced by Stroyproekt or just interesting jobs in the solitary article. Nonetheless, i do want to emphasize a few tasks that mirror our expert philosophy into the brightest method. In 2003 we developed the working and design drawings for reconstruction of this connection over the Volga River in Kimry town of Tver area. When it comes to very first time in Russia, strengthening associated with the current prestressed strengthened tangible field deck ended up being implemented by way of the cable-stayed system. To amount the carriageway we’ve utilised light and nanomodified concrete with bulk weight of 1.6 t/m2 and plastomagnetic balls as opposed to crushed rock. It has permitted increasing the connection ability as much as values that are standard straightening the carriageway profile.
