Neither were we needed to restore a historic appearance of the Lieutenant Schmidt Bridge. Committee on State Control, utilize and Protection of Historical and Cultural Heritage asked for simply to preserve pavilions and plates that are memorial the draw span. But we considered restoration for the bridge look as created by S. Kerbedza to be our expert duty and our responsibility as Petersburgers as well. So we did so, so when rehabilitation had been finished 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 right straight back its initial 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, Use and Protection of Historical and Cultural Heritage. Nevertheless, 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 for 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 regarding the town and asked for extra dishes become set up to mention rehabilitation of 2006 – 2007. Nevertheless, 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 into the center of XIX century its a structure that is modern ere the essential interesting technical solutions happen realised. The connection became one . 5 times wider (from 24 to 36 m wide) and ended up being redesigned for nowadays lots, but during the exact same time we were able to protect historic foundation of wood heaps. It became feasible because of the deck self-weight decrease and a design that is new wh ere the draw span deck is supported perhaps maybe not by piers but by fixed decks. Such structure permitted attaining main bearing regarding the draw piers and excluding eccentricity.

Guss asphalt ended up being used at Blagoveschensky Bridge; by that point it currently gained reputation that is good the draw period of Alexander Nevsky Bridge, at Troitsky Bridge and also at the sign in 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 within our country to perfect this technology that is german. Guss asphalt technology for connection building has resolved a long-lasting issue using 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 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 specific situation with composite strengthened concrete has progressed an additional method. Whenever we first used composite concrete, cast-in-situ concrete had been still remarkably popular within the West and just during the change for the 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 I?tas– Astaldi have already been involved to create probably the most complicated Central Section regarding the Western High Speed Diameter (WHSD). Certainly one of their requests that are first to exclude cast-in-situ concrete structures in support of composite ones. As mentioned by well-known company that is french tpi, that is a consultant of y our universities from Turkey and Italy, cast-in-situ concrete is recognized as conventional within the present-day European countries and it is mostly employed by European businesses 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 dispute that is ideological. The materials that people first introduced about two decades 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.

As for strengthened beams that are concrete unfortunately numerous Russian areas still 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 typical and solution that is workable permits handling drawbacks of this current beam designs without re-equipment of manufacturing flowers. Our idea happens to be accepted definitely and then we wish that the standard that is new design is going to be developed and authorized.

The task of Western High Speed Diameter is actually a quintessence of y our professional experience.

As a whole, the WHSD is definitely a project that is innovative different standpoints. It’s the very first expressway, that may link the southern and north borders of St. Petersburg to your 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 an even more information consideration. Included in this, the bridge that is unique associated with WHSD Central Section that may form up St. Petersburg water Fa?ade, in specific: – a dual deck connection throughout the town top navigation channel, called as water Channel (the bridge is 734 m very long; its central 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 main span is 220 m very long; the underclearance is 25 m).

The most important an element of the WHSD route runs by way of a slim corridor across compact commercial areas. Not enough free area ended up being probably the most pronounced during the section from Stacheck Prospect to your Ekaterinhofka River (Construction phase II). To deal with these constraints our developers have proposed double-deck trusses for this area and in addition for many phase IV sections. Double deck trusses enable breaking up contrary traffic moves towards the reduced and top deck correspondingly (supplying 4 lanes in a choice of traffic way). Horizontally, the trusses are observed for a adjustable radius curve with superelevations and change areas, that will be extremely unusual 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 powerful mode: the arc-shaped illumination poles are incorporated using 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, it really is impractical to offer a complete breakdown of all innovations introduced by Stroyproekt or just interesting jobs in the article that is single. However, i want to emphasize a few tasks that mirror our professional philosophy into the way that is brightest. In 2003 we developed the working and design drawings for reconstruction of this connection over the Volga River in Kimry city of Tver area. When it comes to time that is first 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 place of crushed rock. it has permitted enhancing the connection capability as much as standard values and straightening the carriageway profile.
