Neither were we necessary to restore a historic appearance of the Lieutenant Schmidt Bridge. Committee on State Control, utilize and Protection of Historical and Cultural Heritage asked for and then protect pavilions and plates that are memorial the draw span. But we considered restoration of this connection look as created by S. Kerbedza to be our professional duty and our responsibility as Petersburgers as well. So 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 straight straight straight back its initial name.
The St. Petersburg World Club awarded Institute Stroyproekt a Sign of Conformance for Blagoveschensky Bridge rehabilitation.
The reward that is same directed at Mostootryad 19 and Committee on State Control, utilize and Protection of Historical and Cultural Heritage. But, in this specific situation the Committee merits are not very obvious. In line with the Committee’s requirement the memorial dishes reading that the connection had been called after Lieutenant Schmidt, a hero of this revolution of 1905, and rebuilt in 1930s on the basis of the design by Peredery have already been preserved. We addressed to your Committee indicating why these plates misinform residents and visitors associated with populous town and asked for extra dishes to be set up to say rehabilitation of 2006 – 2007. Nevertheless, we received a refusal to your demand. But we do hope that justice may be finally offered. Though Blagoveschensky Bridge comes back us towards the middle 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 had been redesigned for nowadays loads, but during the time that is same was able to protect historic foundation of 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 perhaps maybe 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 had been used at Blagoveschensky Bridge; by the period 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 training after it absolutely was introduced by ABZ-1 Asphalt concrete plant which was the very first plant within our nation to perfect this technology that is german. Guss asphalt technology for connection building has solved a long-lasting issue aided by the connection flooring at draw spans and orthotropic dish.
European countries is left out for the time being, why don’t we return to our topic that is favorite of reinforced concrete for intensive usage of which we had been bitterly criticized on numerous occasions. Normally, Russian connection industry (and even other spheres) lags far behind the tendencies that are worldwide. State-of-the-art 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 means. Once we first used composite concrete, cast-in-situ concrete ended up being nevertheless popular into the western and just in the change associated with century they began changing to composite concrete. Furthermore, the look 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 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 ones. As mentioned by well-known company that is french tpi, that will be a consultant of our universities from Turkey and Italy, cast-in-situ concrete is known as antique within the present-day European countries and it is mostly employed by European organizations in the under developed countries wh ere there aren’t 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 we first introduced about twenty years ago at our risk that is own is commonly utilized in European countries: composite reinforced tangible proved to be more affordable, more desirable and durable.
In terms of strengthened beams that are concrete unfortuitously numerous Russian areas nevertheless utilize them in connection construction. From our side we now have suggested GK Rosavtodor to change the look of standard strengthened beams that are concrete. Stroyproekt has found a typical and solution that is workable enables managing disadvantages regarding the current beam designs without re-equipment of manufacturing flowers. latin brides Our concept happens to be accepted favorably and now we wish that the standard that is new design are going to be developed and authorized.
The task of Western tall Speed Diameter has grown to become a quintessence of y our professional experience.
As a whole, the WHSD is definitely a revolutionary task from different standpoints. It will be the first expressway, that will link the southern and north borders of St. Petersburg to your town centre. Besides, it is also the toll that is first for the Northern Capital of Russia. Finally, the WHSD project 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 dual deck connection throughout the town top navigation channel, called as water Channel (the bridge is 734 m very very long; its main period is 168 m 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 main period is 220 m long; the underclearance is 25 m).
The major area of the WHSD path runs by way of a corridor that is narrow compact commercial areas. Not enough free area ended up being probably the 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 a few phase IV sections. Double deck trusses enable breaking up traffic that is opposite towards the reduced and top deck correspondingly (supplying 4 lanes in either traffic way). Horizontally, the trusses can be found on an adjustable curve that is radius superelevations and change areas, which can 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 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 is developed in a uniform, recognisable and powerful mode: the arc-shaped illumination poles are incorporated utilizing the curved sound displays. Because of this the WHSD is perceived not only as a long-distance motorway but as a continuing engineering and architectural complex.
“Philosophy” for action needless to say, it really is impractical to provide a complete breakdown of all innovations introduced by Stroyproekt or just interesting jobs in the article that is single. Nonetheless, i do want to emphasize a few jobs that reflect our expert philosophy into the brightest means. In 2003 we developed the working and design drawings for reconstruction associated with the connection throughout the Volga River in Kimry city of Tver area. For the time that is first Russia, strengthening of this current prestressed strengthened tangible field deck had been implemented in the form 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 rather than crushed rock. It has permitted enhancing the connection ability as much as values that are standard straightening the carriageway profile.
