Neither were we needed to restore a look that is historical of Lieutenant Schmidt Bridge. Committee on State Control, utilize and Protection of Historical and Cultural Heritage requested and then protect pavilions and memorial dishes on the draw period. But we considered renovation associated with the connection look as created by S. Kerbedza to be our responsibility that is expert and duty as Petersburgers as well. And now we did therefore, as soon as 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 one way the connection received right right right back its initial title.

The St. Petersburg World Club awarded Institute Stroyproekt a 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 too obvious. In line with the Committee’s requirement the memorial dishes reading that the connection ended up being known as after Lieutenant Schmidt, a hero for the revolution of 1905, and rebuilt in 1930s on the basis of the design by Peredery have now been preserved. We addressed to your Committee showing why these plates misinform residents and visitors of this city and asked for extra dishes become set up to say rehabilitation of 2006 – 2007. But, we received a refusal to your demand. But we do hope that justice may be finally offered. Though Blagoveschensky Bridge returns us into the center of XIX century it’s a structure that is modern 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 ended up being redesigned for nowadays lots, but during the exact same time we was able to preserve historic first step toward wood heaps. It became possible as a result of the deck self-weight decrease and a design that is new wh ere the draw period deck is supported perhaps perhaps not by piers but by fixed decks. Such structure permitted attaining main bearing regarding the draw piers and eccentricity that is excluding.

Guss asphalt ended up being utilized at Blagoveschensky Bridge; by the period it currently gained good reputation at the draw span of Alexander Nevsky Bridge, at Troitsky Bridge as well as the Ring path. We brought guss asphalt technology to Russian bridge building training after it turned out introduced by ABZ-1 Asphalt concrete plant that has been the very first plant within our nation to perfect this German technology. Guss asphalt technology for connection building has resolved a lasting problem utilizing the connection flooring at draw spans and plate that is orthotropic.

Europe is left out for the time being, why don’t we get back to our favorite subject of composite reinforced tangible for intensive utilization of which we had been bitterly criticized on many occasions. Normally, Russian connection industry (and even other spheres) lags far behind the global tendencies. Advanced achievements usually are introduced in some 10– to our country 15-year delay. Nonetheless, the specific situation with composite strengthened concrete has progressed in another 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 style connection with the Western High Speed Diameter in St. Petersburg has shown soundness of our place.

The Turkish and Italian Consortium IC Iзtas– Astaldi have already been involved to create the essential complicated Central Section regarding the Western High Speed Diameter (WHSD). 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, that is a consultant of our colleges from Turkey and Italy, cast-in-situ concrete is regarded as conventional when you look at the present-day Europe and it is mostly employed by European businesses into 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 material 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, more desirable and durable.

In terms of reinforced tangible beams, unfortuitously many Russian areas nevertheless make use of them in bridge construction. From our side we’ve recommended GK Rosavtodor to change the look of standard strengthened beams that are concrete. Stroyproekt has discovered a standard and solution that is workable enables handling drawbacks associated with current beam designs without re-equipment of manufacturing flowers. Our concept happens to be accepted definitely so we wish that a brand new standard beam design will undoubtedly be developed and authorized.

The task of Western tall Speed Diameter has grown to become a quintessence of y our expert experience.

Generally speaking, the WHSD is definitely a project that is innovative different standpoints. This is the first expressway, that may link the southern and north borders of St. Petersburg to your town centre. Besides, additionally it is the toll that is first associated with 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 regarding the WHSD Central Section that may form up St. Petersburg Sea Faзade, in specific: – a double deck connection throughout the city top navigation channel, named as water 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 very long; its central period is 220 m very very long; the underclearance is 25 m).

The main area of the WHSD path runs through a corridor that is narrow compact industrial areas. Not enough free area ended up being the absolute most pronounced in the area 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 splitting traffic that is opposite to your reduced and top deck correspondingly (supplying 4 lanes in either traffic way). Horizontally, the trusses can be found for a adjustable radius curve with superelevations and change areas, that will be extremely 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 was developed in a uniform, recognisable and powerful mode: the arc-shaped lighting poles buy mail order bride are incorporated aided by the curved sound displays. Because of this the WHSD is perceived not merely as a long-distance motorway but as a continuing engineering and architectural complex.

“Philosophy” for action Of course, it really is impractical to offer a complete breakdown 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 within 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 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 now have utilised light and nanomodified concrete with bulk weight of 1.6 t/m2 and plastomagnetic balls rather than crushed rock. It has permitted enhancing the connection capability up to standard values and straightening the carriageway profile.
