Neither were we necessary to restore a look that is historical of Lieutenant Schmidt Bridge. Committee on State Control, utilize and Protection of Historical and Cultural Heritage asked for simply to protect pavilions and plates that are memorial the draw period. But we considered renovation of this connection look as created by S. Kerbedza to be our expert responsibility and our duty as Petersburgers as well. And now we did so, so when rehabilitation had been finished it became clear for the town management it was maybe not Lieutenant Schmidt Bridge any longer, it had been Blagoveschensky Bridge. This is one way the connection received straight right 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 ended up being directed at Mostootryad 19 and Committee on State Control, utilize and Protection of Historical and Cultural Heritage. But, in this case that is particular Committee merits are not 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 in line with the design by Peredery have now been preserved. We addressed to the Committee indicating why these plates misinform citizens and guests of this populous town and asked for extra dishes become set up to say rehabilitation of 2006 – 2007. But, a refusal was received by us to the request. But we do hope that justice may be finally offered. Though Blagoveschensky Bridge comes back us to your middle of XIX century it’s a contemporary structure wh ere the essential interesting technical solutions have now 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 been able to protect 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 perhaps perhaps 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 period of Alexander Nevsky Bridge, at Troitsky Bridge and also at the Ring Road. We brought guss asphalt technology to Russian connection building training after it turned out introduced by ABZ-1 Asphalt concrete plant which was the initial plant inside our nation to understand this German technology. Guss asphalt technology for connection building has resolved a long-lasting issue because of the connection flooring at draw spans and orthotropic dish.

European countries is put aside for the time being, why don’t we return to our topic that is favorite of reinforced tangible for intensive usage of which we had been bitterly criticized on numerous 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. But, the specific situation with composite strengthened concrete has progressed an additional way. Once we first used composite concrete, cast-in-situ concrete had been nevertheless remarkably popular within the western and just during the change associated with century they began changing to composite concrete. More over, the look connection with the Western tall Speed Diameter in St. Petersburg has shown soundness of our position.

The Turkish and Italian Consortium IC Iзtas– Astaldi have now been involved to create the essential 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 in support of composite people. As stated by well-known French company Setec tpi, that is a consultant of our universities from Turkey and Italy, cast-in-situ concrete is regarded as conventional into the present-day European countries and it is mostly utilized 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 right for the reason that long-standing dispute that is ideological. The material we first introduced about twenty years ago at our risk that is own is commonly utilized in European countries: composite reinforced tangible latin brides proved to be less costly, considerably better and durable.

As for strengthened tangible beams, unfortunately numerous Russian areas nevertheless utilize them in bridge construction. From our part we now have recommended GK Rosavtodor to change the look of standard strengthened tangible beams. Stroyproekt has discovered a typical and solution that is workable permits managing drawbacks of this present beam designs without re-equipment of manufacturing flowers. Our idea happens to be accepted definitely and now we wish that a brand new standard beam design would be developed and authorized.

The task of Western tall Speed Diameter is a quintessence of y 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 your town centre. Besides, it’s also 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. Included in this, the unique connection structures associated with WHSD Central Section which will form up St. Petersburg water Faзade, in specific: – a double deck connection throughout the town top navigation channel, called as water Channel (the bridge is 734 m 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 connection across Petrovsky Channel (the connection is 580 m very long; its central period is 220 m very long; the underclearance is 25 m).

The main an element of the WHSD path runs by way of a slim corridor across compact industrial areas. Not enough free room was the absolute most pronounced in the part from Stacheck Prospect to your Ekaterinhofka River (Construction phase II). To handle these constraints our developers have proposed trusses that are double-deck this area and in addition for many phase IV sections. Double deck trusses enable separating traffic that is opposite towards the reduced and top deck correspondingly (supplying 4 lanes either in traffic way). Horizontally, the trusses are situated on a adjustable curve that is radius superelevations and change areas, which can be really unusual for dual deck structures. The longest span is 144 m.

The WHSD design includes various other solutions that are not so large-scale yet still quite interesting. The toll plaza at the exit ramp to Automobilnaya Street (Stage I) can be taken which has been constructed on two levels due to the extremely space-limited area as an example. 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 sound displays. Because of this the WHSD is sensed not merely as a long-distance motorway but as a continuous engineering and architectural complex.

“Philosophy” for action Of course, it really is impractical to provide a complete breakdown of all innovations introduced by Stroyproekt or just interesting tasks in the article that is single. However, i want to emphasize a few tasks that mirror our expert philosophy into the way that is brightest. In 2003 we developed the design and dealing drawings for reconstruction regarding the connection over the Volga River in Kimry city of Tver area. For the time that is first Russia, strengthening associated with existing prestressed strengthened tangible package deck ended up being implemented by way 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 in the place of crushed rock. It has permitted enhancing the connection capability as much as standard values and straightening the carriageway profile.
