Neither were we necessary to restore a historical appearance of the Lieutenant Schmidt Bridge. Committee on State Control, utilize and Protection of Historical and Cultural Heritage requested simply to protect pavilions and memorial plates on the draw period. But we considered renovation associated with the connection look as designed by S. Kerbedza to be our expert responsibility and our responsibility as Petersburgers as well. And we also did therefore, so when rehabilitation ended up being completed it became clear for the city management it was Blagoveschensky Bridge that it was not Lieutenant Schmidt Bridge any more. 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 reward that is same directed at Mostootryad 19 and Committee on State Control, utilize and Protection of Historical and Cultural Heritage. Nonetheless, in this specific situation the Committee merits are not obvious. On the basis of the Committee’s requirement the memorial dishes reading that the connection ended up being known as after Lieutenant Schmidt, a hero associated with revolution of 1905, and rebuilt in 1930s in line with the design by Peredery have now been preserved. We addressed into the Committee showing why these plates misinform residents and visitors of this populous town and asked for additional dishes to be installed to mention rehabilitation of 2006 – 2007. Nevertheless, a refusal was received by us to your request. But we do hope that justice might be finally offered. Though Blagoveschensky Bridge comes back us to your middle of XIX century it really is a structure that is modern ere the essential interesting technical solutions have already been realised. The connection became one and a half times wider (from 24 to 36 m wide) and ended up being redesigned for nowadays lots, but during the same time we was 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 perhaps not by piers but by fixed decks. Such structure permitted attaining main bearing in the draw piers and eccentricity that is excluding.
Guss asphalt had been utilized at Blagoveschensky Bridge; by the period it currently gained reputation that is good the draw period of Alexander Nevsky Bridge, at Troitsky Bridge and also at 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 understand this technology that is german. Guss asphalt technology for connection building has fixed a lasting issue aided by the connection flooring at draw spans and plate that is orthotropic.
European countries is left out for the time being, let’s get back to our topic that is favorite of reinforced concrete 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 global tendencies. Advanced achievements usually are introduced in our nation with a few 10 – 15-year delay. Nonetheless, the specific situation with composite strengthened concrete has progressed an additional method. Once we first used composite concrete, cast-in-situ concrete ended up being still remarkably popular within the western and just in the change associated with the century they began changing to composite concrete. Furthermore, the style 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 now been involved to construct the essential complicated Central Section associated with 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 people. As previously mentioned by well-known company that is french tpi, which will be a consultant of our universities from Turkey and Italy, cast-in-situ concrete is known as conventional into 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.
So, we got convinced of who was actually appropriate in that long-standing dispute that is ideological. The materials that people first introduced about twenty years ago at our risk that is own is commonly found in European countries: composite reinforced tangible proved to be more affordable, more desirable and sturdy.
In terms of strengthened concrete beams, regrettably numerous Russian areas still make use of them in connection construction. From our part we now have suggested GK Rosavtodor to change the design of standard reinforced tangible beams. Stroyproekt has found a standard and practical solution that enables handling drawbacks regarding the present beam designs without re-equipment of manufacturing flowers. Our concept happens to be accepted absolutely and then we wish that a standard that is new design may be developed and authorized.
The task of Western tall Speed Diameter is now a quintessence of y our expert experience.
Generally speaking, the WHSD is 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 city centre. Besides, it’s also the very first toll motorway associated with the Northern Capital of Russia. Finally, the WHSD project includes a latin women dating few design solutions that deserve a far more information consideration. One of them, the bridge that is unique of this WHSD Central Section that may form up St. Petersburg water Faзade, in specific: – a dual deck connection throughout the town top navigation channel, called as Sea Channel (the bridge is 734 m very 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 period is 320 m long; the underclearance is 35 m); – The extrados connection across Petrovsky Channel (the connection is 580 m long; its main period is 220 m very very long; the underclearance is 25 m).
The most important the main WHSD path runs through a corridor that is narrow compact commercial areas. Not enough free area ended up being probably the most pronounced during the part from Stacheck Prospect towards 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 many phase IV sections. Double deck trusses enable splitting other traffic moves to your reduced and top deck correspondingly (supplying 4 lanes in either traffic way). Horizontally, the trusses are observed on an adjustable radius curve with superelevations and change areas, which will be very uncommon for dual deck structures. The longest period is 144 m.
The WHSD design includes various other solutions that are not therefore large-scale but nevertheless 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 designed in a uniform, recognisable and mode that is dynamic the arc-shaped illumination poles are incorporated utilizing the curved sound screens. Because of this the WHSD is identified not only as a long-distance motorway but as a continuous engineering and architectural complex.
“Philosophy” for action needless to say, it really is impractical to provide a complete 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 brightest means. In 2003 we developed the design and working drawings for reconstruction for the connection throughout the Volga River in Kimry city of Tver area. For the time that is first Russia, strengthening regarding the current prestressed strengthened tangible package deck had been 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 stone. It has permitted enhancing the connection capability as much as standard values and straightening the carriageway profile.
