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 protect pavilions and plates that are memorial the draw period. But we considered renovation regarding the connection look as created by S. Kerbedza to be our expert responsibility and our responsibility as Petersburgers as well. Therefore 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 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 same reward ended up being provided to Mostootryad 19 and Committee on State Control, utilize and Protection of Historical and Cultural Heritage. Nonetheless, in this case that is particular Committee merits are not too obvious. On the basis of the Committee’s requirement the memorial dishes reading that the connection had been called after Lieutenant Schmidt, a hero regarding the revolution of 1905, and rebuilt in 1930s in line with the design by Peredery were preserved. We addressed to your Committee showing why these plates misinform residents and visitors regarding the town and asked for extra dishes become set up to say rehabilitation of 2006 – 2007. Nevertheless, we received a refusal 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's 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 were able to protect historic first step toward wood heaps. It became possible because of the deck self-weight decrease and a brand new design solution wh ere the draw span deck is supported maybe perhaps not by piers but by fixed decks. Such structure permitted achieving main bearing from the draw piers and eccentricity that is excluding.

Guss asphalt ended up being utilized at Blagoveschensky Bridge; by that point it currently gained reputation that is good the draw course 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 absolutely was introduced by ABZ-1 Asphalt concrete plant which was 1st plant within our nation to perfect this German technology. Guss asphalt technology for connection building has fixed a long-lasting problem because of the connection flooring at draw spans and orthotropic dish.

European countries is left behind for the time being, why don't we go back to our topic that is favorite of reinforced tangible for intensive usage 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 our nation with a few 10 – 15-year delay. But, the problem with composite strengthened concrete has progressed an additional method. Whenever we first used composite concrete, cast-in-situ concrete had been nevertheless extremely popular within the western and just during the change regarding 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 our place.

The Turkish and Consortium that is italian IC– Astaldi have now been involved to create the essential complicated Central Section associated with the Western High Speed Diameter (WHSD). Certainly one of their very first demands had been 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 y our universities from Turkey and Italy, cast-in-situ concrete is recognized as conventional into the present-day European countries 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 materials that people first introduced about twenty years ago at our risk that is own is commonly utilized in European countries: composite reinforced tangible proved asian brides to be less costly, considerably better and sturdy.

In terms of strengthened beams that are concrete regrettably numerous Russian areas nevertheless make use of them in connection construction. From our part we've recommended GK Rosavtodor to change the design of standard strengthened beams that are concrete. Stroyproekt has discovered a typical and solution that is workable permits handling drawbacks regarding the current beam designs without re-equipment of manufacturing plants. Our concept was accepted favorably and we also wish that a standard that is new design will likely to be developed and authorized.

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

As a whole, the WHSD is definitely a innovative task from different standpoints. It will be the expressway that is first that may link the southern and north outskirts of St. Petersburg to your town centre. Besides, additionally it is the toll that is first for the Northern Capital of Russia. Finally, the WHSD task includes a few design solutions that deserve a far more information consideration. One of them, the unique connection structures for the WHSD Central Section that may form up St. Petersburg water Faзade, in specific: - a dual deck connection throughout the town top navigation channel, known as as water Channel (the bridge is 734 m very long; its main period is 168 m very 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 very very long; its main period is 220 m very very long; the underclearance is 25 m).

The most important the main WHSD path runs via a slim corridor across compact industrial areas. Not enough free area ended up being probably the most pronounced during the part 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 as well as for a few phase IV sections. Double deck trusses enable isolating contrary traffic flows to your reduced and top deck correspondingly (supplying 4 lanes in a choice of traffic way). Horizontally, the trusses are found on an adjustable radius curve with superelevations and transition areas, which can be extremely uncommon for dual deck structures. The longest span is 144 m.

The WHSD design includes various other solutions that are not 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 lighting 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's impractical to provide a complete breakdown of all innovations introduced by Stroyproekt or just interesting tasks inside the solitary article. However, i must emphasize a few tasks that mirror our expert philosophy into the way that is brightest. In 2003 we developed the design and working drawings for reconstruction for the 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 package deck had been implemented by means 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 stone. It has permitted enhancing the connection capability as much as values that are standard straightening the carriageway profile.
