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 memorial dishes on the draw period. But we considered renovation for the connection look as created by S. Kerbedza to be our duty that is expert and responsibility as Petersburgers as well. So we did therefore, so when rehabilitation ended up being finished it became clear when it comes to town management it was Blagoveschensky Bridge that it was not Lieutenant Schmidt Bridge any more. This is the way the connection received straight right back its original title.

The St. Petersburg World Club awarded Institute Stroyproekt an indication of Conformance for Blagoveschensky Bridge rehabilitation.

The reward that is same 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 very obvious. On the basis of the Committee’s requirement the memorial dishes reading that the connection had been called after Lieutenant Schmidt, a hero associated with revolution of 1905, and rebuilt in 1930s in line with the design by Peredery have already been preserved. We addressed towards the Committee indicating why these plates misinform residents and guests of this town and asked for extra dishes become set up to say rehabilitation of 2006 – 2007. Nevertheless, we received a refusal to your demand. But we do hope that justice might be finally offered. Though Blagoveschensky Bridge comes back us into the center of XIX century it really is a structure that is modern ere the essential 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 during the exact same time we was 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 maybe not by piers but by fixed decks. Such structure permitted attaining main bearing in the draw piers and excluding eccentricity.

Guss asphalt ended up being utilized at Blagoveschensky Bridge; by that point it currently gained good reputation at the draw period 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 initial plant within our nation to perfect this technology that is german. Guss asphalt technology for connection building has resolved a long-lasting issue utilizing the connection flooring at draw spans and orthotropic dish.

European countries is left out for the time being, why don’t we get back to our favorite subject of composite reinforced tangible for intensive usage 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 some 10– to our country 15-year delay. But, the problem with composite reinforced concrete has progressed an additional method. 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 proved soundness of our place.

The Turkish and Italian Consortium IC Iзtas– Astaldi have now been involved to create the essential complicated Central Section for the 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 people. As previously mentioned by well-known French company Setec tpi, that is a consultant of our universities from Turkey and Italy, cast-in-situ concrete is known as antique into the present-day European countries and it is mostly utilized by European businesses in the Third World 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 dispute that is ideological. The product we first introduced about two decades ago at our very own risk happens to be commonly utilized in European countries: composite reinforced tangible proved to be less costly, considerably better and durable.

In terms of strengthened tangible beams, unfortunately numerous Russian areas nevertheless make use of them in connection construction. From our part we’ve recommended GK Rosavtodor to change the look of standard strengthened beams that are concrete. Stroyproekt has discovered a typical and solution that is workable permits handling drawbacks for the current beam designs without re-equipment of manufacturing flowers. Our concept happens to be accepted favorably therefore we wish that the standard that is new design are developed and authorized.

The task of Western tall Speed Diameter happens to be 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 will link the southern and north borders of St. Petersburg to your town centre. Besides, it’s also the toll that is first associated with the Northern Capital of Russia. Finally, the WHSD task includes a few design solutions that deserve an even more information consideration. One of them, the bridge that is unique for the WHSD Central Section which will form up St. Petersburg water Faзade, in particular: – a dual deck connection throughout the town top navigation channel, called as Sea Channel (the bridge is 734 m very long; its main period is 168 m very very long; the underclearance is 52 m); – A cable-stayed connection across Korabelny Fairway (the bridge is 620 m long; its main span is 320 m long; the underclearance is 35 m); – The extrados connection across Petrovsky Channel (the connection is 580 m very long; its main period is 220 m very long; the underclearance is 25 m).

The most important area of the WHSD path runs through a slim corridor across compact industrial areas. Insufficient free space ended up being the absolute most pronounced during the area from Stacheck Prospect into the Ekaterinhofka River (Construction phase II). To handle these constraints our developers have proposed trusses that are double-deck this area and in addition for a few Stage IV sections. Double deck trusses enable splitting traffic that is opposite to your reduced and top deck correspondingly (supplying 4 lanes in either traffic way). Horizontally, the trusses are observed for an adjustable radius curve with superelevations and transition areas, which can 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 but nonetheless 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 is developed in a uniform, recognisable and mode that is dynamic the arc-shaped illumination poles are incorporated with all the curved sound displays. That is why the WHSD is identified not merely as a long-distance motorway but as a consistent engineering and architectural complex.

“Philosophy” for action needless to say, it really is find latin brides impractical to provide the full breakdown of all innovations introduced by Stroyproekt or just interesting jobs inside the solitary article. Nonetheless, i must highlight 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 regarding the connection throughout the Volga River in Kimry city of Tver area. For the very first time in Russia, strengthening associated with existing prestressed strengthened tangible field deck ended up being implemented by way of the cable-stayed system. To amount the carriageway we now have utilised light and concrete that is nanomodified bulk weight of 1.6 t/m2 and plastomagnetic balls in the place of crushed rock. It has permitted increasing the bridge capability as much as standard values and straightening the carriageway profile.
