Neither were we expected to restore a look that is historical of Lieutenant Schmidt Bridge. Committee on State Control, Use and Protection of Historical and Cultural Heritage asked for and then protect pavilions and plates that are memorial the draw period. But we considered renovation associated with connection look as created by S. Kerbedza to be our duty that is expert and duty as Petersburgers as well. And now we did therefore, as soon as rehabilitation had been finished it became clear when it comes to city management it was maybe not Lieutenant Schmidt Bridge more, it absolutely was Blagoveschensky Bridge. This is the way the connection received 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 provided to 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 too obvious. On the basis of the Committee’s requirement the memorial dishes reading that the connection ended up being called after Lieutenant Schmidt, a hero associated with the revolution of 1905, and rebuilt in 1930s on the basis of the design by Peredery have now been preserved. We addressed into the Committee showing why these plates misinform citizens and visitors associated with town and asked for extra dishes become installed to say rehabilitation of 2006 – 2007. Nonetheless, a refusal was received by us to the demand. But we do hope that justice might be finally offered. Though Blagoveschensky Bridge comes back us towards the center of XIX century it really is a contemporary framework wh 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 had been redesigned for nowadays lots, but in the exact same time we was 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 maybe maybe maybe not by piers but by fixed decks. Such structure permitted attaining main bearing regarding the draw piers and eccentricity that is excluding.

Guss asphalt had been utilized at Blagoveschensky Bridge; by that point it currently gained reputation that is good 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 practice 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 bridge building has resolved a long-lasting issue with all the connection flooring at draw spans and plate that is orthotropic.

European countries is left out for the time being, why don’t we return to our topic that is favorite of reinforced tangible for intensive utilization 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 country with a few 10 – 15-year delay. Nevertheless, the specific situation with composite strengthened concrete has progressed an additional method. They started changing to composite concrete when ukrainian brides club we first applied composite concrete, cast-in-situ concrete was still very popular in the West and only at the turn of the century. More over, the look connection with the Western tall Speed Diameter in St. Petersburg has shown soundness of our place.

The Turkish and Italian Consortium IC Iзtas– Astaldi have now been involved to create probably the most complicated Central Section associated with Western High Speed Diameter (WHSD). Certainly one of their very first demands ended up being to exclude cast-in-situ concrete structures and only composite people. As previously mentioned by well-known French company Setec tpi, that will be a consultant of our universities from Turkey and Italy, cast-in-situ concrete is regarded as conventional when you look at the present-day European countries and it is mostly employed by European organizations 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 ideological dispute. 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 less costly, considerably better and durable.

As for strengthened beams that are concrete unfortuitously numerous Russian areas nevertheless 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 standard and solution that is workable enables handling drawbacks for the current beam designs without re-equipment of manufacturing flowers. Our idea happens to be accepted absolutely so we wish that the standard that is new design is going to be developed and authorized.

The task of Western tall Speed Diameter is actually a quintessence of y our expert experience.

Generally speaking, the WHSD is a project that is innovative different standpoints. It will be the very first expressway, that will link the southern and north outskirts of St. Petersburg to your city centre. Besides, additionally it is the very first toll motorway associated with the Northern Capital of Russia. Finally, the WHSD task includes a few design solutions that deserve an even more detail consideration. Included in this, the unique connection structures associated with the WHSD Central Section which will form up St. Petersburg water Faзade, in specific: – a double deck bridge over the town top navigation channel, called as water Channel (the bridge is 734 m long; its main span is 168 m 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 very long; its main period is 220 m long; the underclearance is 25 m).

The main an element of the WHSD path runs via a corridor that is narrow compact commercial areas. Insufficient free space ended up being probably the most pronounced during the part from Stacheck Prospect to your Ekaterinhofka River (Construction Stage II). To deal with these constraints our developers have proposed trusses that are double-deck this area and in addition for a few phase IV sections. Double deck trusses enable isolating traffic that is opposite towards the reduced and top deck correspondingly (supplying 4 lanes in either traffic way). Horizontally, the trusses are situated for an adjustable radius curve with superelevations and change areas, which can be really uncommon for dual deck structures. The longest period is 144 m.

The WHSD design includes other solutions that are not therefore 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 aided by the curved sound screens. 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 Of course, its impractical to provide a complete summary of all innovations introduced by Stroyproekt or just interesting jobs inside the article that is single. However, i must highlight a few jobs that mirror our expert philosophy within the brightest method. In 2003 we developed the design and working drawings for reconstruction associated with connection throughout the Volga River in Kimry city of Tver Region. For the time that is first Russia, strengthening regarding the current prestressed reinforced 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 in the place of crushed stone. It has permitted enhancing the connection ability as much as values that are standard straightening the carriageway profile.
