the language “Aesthetics of Reliability” as our formal motto fr om very very very long ago reflect maybe not only an over-all expert philosophy but additionally a specific expert approach

Neither were we expected to restore a historic appearance of the Lieutenant Schmidt Bridge. Committee on State Control, Use and Protection of Historical and Cultural Heritage asked for simply to protect pavilions and memorial dishes on the draw span. But we considered renovation for the connection appearance as created by S. Kerbedza to be our expert responsibility and our responsibility as Petersburgers as well. Therefore we did so, so when rehabilitation had been finished it became clear when it comes to town administration it was Blagoveschensky Bridge that it was not Lieutenant Schmidt Bridge any more. This is one way the connection received right straight straight back its original name.

The St. Petersburg World Club awarded Institute Stroyproekt an indication of Conformance for Blagoveschensky Bridge rehabilitation.

The exact same reward had been directed at Mostootryad 19 and Committee on State Control, utilize and Protection of Historical and Cultural Heritage. Nevertheless, in this case that is particular Committee merits are not too obvious. In line with the Committee’s requirement the memorial plates 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 have already been preserved. We addressed towards the Committee showing that these plates misinform citizens and visitors associated with populous town 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 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 now been realised. The connection became one . 5 times wider (from 24 to 36 m wide) and ended up being redesigned for nowadays lots, but in the exact same time we were able to preserve historic foundation of wood heaps. It became possible because of the deck self-weight decrease and a brand new design solution wh ere the draw period deck is supported perhaps not by piers but by fixed decks. Such structure permitted attaining main bearing from the draw piers and excluding eccentricity.

Guss asphalt had been utilized at Blagoveschensky Bridge; by that point it currently gained good reputation at the draw course 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 absolutely was introduced by ABZ-1 Asphalt concrete plant that has been the very first plant inside our nation to perfect this German technology. Guss asphalt technology for connection building has fixed a long-lasting issue aided by the bridge flooring at draw spans and orthotropic dish.

European countries is left out for the time being, let’s get 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. State-of-the-art achievements usually are introduced in some 10– to our country 15-year delay. Nevertheless, the problem with composite reinforced concrete has progressed an additional means. 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 tall Speed Diameter in St. Petersburg has proved soundness of y our place.

The Turkish and Consortium that is italian IC– Astaldi are involved to create probably the most complicated Central Section regarding the Western High Speed Diameter (WHSD). One of their requests that are first to exclude cast-in-situ concrete structures and only 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 regarded as traditional into 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 two decades ago at our very own danger has become commonly utilized in European countries: composite reinforced tangible proved to be more affordable, considerably better and sturdy.

In terms of strengthened beams that are concrete regrettably numerous Russian areas nevertheless utilize them in connection construction. From our part we now have suggested GK Rosavtodor to modify the look of standard reinforced tangible beams. Stroyproekt has discovered a typical and workable solution that enables handling drawbacks for the current beam designs without re-equipment of manufacturing flowers. Our concept happens to be accepted favorably and now we wish that the brand new standard beam design will soon be developed and authorized.

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

As a whole, the WHSD is a innovative task from different standpoints. This is the expressway that is first that may link the southern and northern borders of St. Petersburg to your city centre. Besides, it’s also the toll that is first associated with 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 Faзade, in specific: – a double deck bridge throughout the town top navigation channel, known as as water Channel (the bridge is 734 m very long; its main period 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 central period is 220 m very very 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 room was probably the most pronounced during the part from Stacheck Prospect into the Ekaterinhofka River (Construction phase II). To deal with these constraints our developers have proposed double-deck trusses for this part as well as for a few Stage IV sections. Double deck trusses allow breaking up traffic that is opposite into the lower and top deck correspondingly (supplying 4 lanes in either traffic way). Horizontally, the trusses are observed on an adjustable curve that is radius superelevations and change areas, which will be extremely uncommon for dual deck structures. The longest span is 144 m.

The WHSD design includes various other solutions that are not so 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 illumination poles are integrated using the curved sound displays. That is why the WHSD is sensed not only as a long-distance motorway but as a continuing engineering and architectural complex.

“Philosophy” for action needless to say, it’s impractical to provide a complete summary of all innovations introduced by Stroyproekt or just interesting tasks in the article that is single. However, i do want to emphasize a few tasks that mirror our expert philosophy into the brightest means. In 2003 we developed the working and design drawings for reconstruction of this connection throughout the Volga River in Kimry city of Tver area. For the time that is first Russia, strengthening associated with 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 rock. It has permitted increasing the bridge ability as much as values that are standard straightening the carriageway profile.
