Neither were we necessary to restore a historical appearance of the 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 span. But we considered renovation associated with the connection look as created 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 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 straight straight back its initial name.
The St. Petersburg World Club awarded Institute Stroyproekt a indication of Conformance for Blagoveschensky Bridge rehabilitation.
The exact same reward had been fond of Mostootryad 19 and Committee on State Control, utilize and Protection of Historical and Cultural Heritage. But, in this particular instance the Committee merits are not very obvious. In line with 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 in line with the design by Peredery have already been preserved. We addressed towards the Committee showing why these plates misinform residents and visitors of this populous town and asked for extra dishes become set up to say rehabilitation of 2006 – 2007. Nonetheless, we received a refusal to your demand. But we do hope that justice may be finally offered. Though Blagoveschensky Bridge returns us towards the center of XIX century its a structure that is modern ere the essential 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 during the time that is same were able to protect historic first step toward wood heaps. It became feasible as a result of the deck self-weight decrease and a design that is new wh ere the draw period deck is supported maybe perhaps not by piers but by fixed decks. Such structure permitted attaining main bearing from the draw piers and excluding eccentricity.
Guss asphalt ended up being utilized at Blagoveschensky Bridge; by that point it currently gained reputation that is good the draw period of Alexander Nevsky Bridge, at Troitsky Bridge and also at the Ring Road. We brought guss asphalt technology to Russian connection building training after it absolutely was introduced by ABZ-1 Asphalt concrete plant that has been the initial plant inside our nation to perfect this German technology. Guss asphalt technology for connection building has fixed a lasting issue because of the connection flooring at draw spans and orthotropic dish.
European countries is left behind 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 nation with a few 10 – 15-year delay. But, the specific situation with composite strengthened concrete has progressed an additional 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 latin teen brides century. More over, the look connection with the Western tall Speed Diameter in St. Petersburg has shown soundness of y our position.
The Turkish and Italian Consortium IC Iзtas– Astaldi have already been engaged to create probably the most complicated Central Section for the Western High Speed Diameter (WHSD). Certainly one of their requests that are first to exclude cast-in-situ concrete structures and only composite people. As mentioned by well-known French company Setec tpi, which will be a consultant of y our universities from Turkey and Italy, cast-in-situ concrete is recognized as traditional into the present-day European countries and it is mostly employed by European businesses when you look at the under developed countries wh ere there are not any qualified steelwork manufacturers.
So, we got convinced of who had been actually appropriate in that long-standing ideological dispute. The product that people first introduced about twenty years ago at our own danger has become commonly found in European countries: composite reinforced tangible proved to be more affordable, more suitable and durable.
In terms of strengthened concrete beams, regrettably numerous Russian areas nevertheless utilize them in connection construction. From our part we’ve recommended GK Rosavtodor to change the look of standard strengthened beams that are concrete. Stroyproekt has discovered a typical and solution that is workable enables handling drawbacks for the current beam designs without re-equipment of manufacturing flowers. Our concept happens to be accepted absolutely so we hope that the standard that is new design would be developed and authorized.
The task of Western tall Speed Diameter is now a quintessence of our expert experience.
As a whole, the WHSD is definitely a revolutionary task from various standpoints. It’s the expressway that is first that will link the southern and north borders of St. Petersburg to your town centre. Besides, it’s also the toll that is first regarding the Northern Capital of Russia. Finally, the WHSD task includes a few design solutions that deserve a far more information consideration. Included in this, the bridge that is unique associated with the WHSD Central Section that may form up St. Petersburg water Faзade, in specific: – a dual deck connection over the town top navigation channel, called as water Channel (the bridge is 734 m very long; its main period is 168 m very long; the underclearance is 52 m); – A cable-stayed bridge 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 bridge is 580 m very very long; its main span is 220 m very very long; the underclearance is 25 m).
The most important area of the WHSD path runs via a corridor that is narrow compact commercial areas. Not enough free area ended up being the absolute most pronounced during the area from Stacheck Prospect towards the Ekaterinhofka River (Construction phase II). To deal with these constraints our developers have proposed trusses that are double-deck this area as well as for many phase IV sections. Double deck trusses enable breaking up traffic that is opposite towards the reduced and top deck correspondingly (providing 4 lanes in either traffic way). Horizontally, the trusses can be found for an 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 aren’t 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 dynamic mode: the arc-shaped illumination poles are incorporated because of 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 really is impractical to offer the full summary of all innovations introduced by Stroyproekt or just interesting jobs inside the article that is single. However, i do want to emphasize a few jobs that mirror our expert philosophy into the brightest method. In 2003 we developed the working and design drawings for reconstruction associated with the connection over the Volga River in Kimry city of Tver area. For the very first time in Russia, strengthening of this current prestressed strengthened tangible field deck ended up being implemented by way of the cable-stayed system. To amount the carriageway we’ve utilised light and nanomodified concrete with bulk weight of 1.6 t/m2 and plastomagnetic balls rather than crushed rock. It has permitted increasing the connection capability as much as values that are standard straightening the carriageway profile.
