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 associated with the connection look as created by S. Kerbedza to be our duty that is expert and responsibility as Petersburgers as well. So we did so, as soon as rehabilitation had been finished it became clear for the town management it was Blagoveschensky Bridge that it was not Lieutenant Schmidt Bridge any more. This is the way the connection received right straight straight back its initial title.

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

The same reward was provided to Mostootryad 19 and Committee on State Control, utilize and Protection of Historical and Cultural Heritage. Nonetheless, in this specific instance the Committee merits are not too obvious. In line with the Committee’s requirement the memorial dishes reading that the connection ended up being named after Lieutenant Schmidt, a hero associated with revolution of 1905, and rebuilt in 1930s on the basis of the design by Peredery were preserved. We addressed to your Committee showing why these plates misinform residents and visitors for the town and asked for extra dishes become set up to say rehabilitation of 2006 – 2007. But, a refusal was received by us to the demand. But we do hope that justice may be finally offered. Though Blagoveschensky Bridge comes back us into the center of XIX century its a contemporary framework wh ere the essential interesting technical solutions have already been realised. The connection became one . 5 times wider (from 24 to 36 m wide) and was redesigned for nowadays loads, but during the same time we was able to protect historic foundation of wood heaps. It became possible as a result of the deck self-weight decrease and a brand new design solution wh ere the draw period deck is supported perhaps perhaps maybe not by piers but by fixed decks. Such structure allowed attaining main bearing from the draw piers and eccentricity that is excluding.

Guss asphalt had been utilized 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 turned out 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 long-lasting issue because of the connection floor at draw spans and plate that is orthotropic.

European countries is left out for the time being, let’s return to our favorite subject of composite reinforced tangible for intensive utilization of which we had been bitterly criticized on many occasions. Normally, Russian bridge industry (and even other spheres) lags far behind the global tendencies. Advanced achievements are often introduced in our nation with a few 10 – 15-year delay. Nonetheless, the problem 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 century. Furthermore, the style connection with the Western tall Speed Diameter in St. Petersburg has shown soundness of our position.

The Turkish and Italian Consortium IC Iзtas– Astaldi have already been involved to create probably the most complicated Central Section associated with Western High Speed Diameter (WHSD). Certainly one of their requests that are first to exclude cast-in-situ concrete structures in support of composite people. As 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 recognized as conventional within the present-day European countries and it is mostly utilized by European businesses in 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 product that people first introduced about two decades 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 tangible beams, regrettably numerous Russian areas nevertheless make use of them in connection construction. From our part we now have where can i get a mail order bride recommended GK Rosavtodor to change the look of standard strengthened beams that are concrete. Stroyproekt has discovered a common and solution that is workable permits handling disadvantages for the current beam designs without re-equipment of manufacturing flowers. Our concept was accepted definitely and now we wish that a standard that is new design is likely to be developed and authorized.

The task of Western tall Speed Diameter happens to be a quintessence of y our expert experience.

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

The main the main WHSD path runs through a narrow corridor across compact commercial areas. Not enough free room ended up being probably the most pronounced during the section from Stacheck Prospect to your Ekaterinhofka River (Construction phase II). To deal with these constraints our developers have proposed double-deck trusses for this area and in addition for a few phase IV sections. Double deck trusses enable splitting other traffic moves into the reduced and top deck correspondingly (supplying 4 lanes in a choice of traffic direction). Horizontally, the trusses are found for a adjustable curve that is radius superelevations and transition zones, that is 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 route was developed in a uniform, recognisable and mode that is dynamic the arc-shaped illumination poles are incorporated utilizing 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 the full summary of all innovations introduced by Stroyproekt or just interesting tasks inside the article that is single. Nonetheless, i must emphasize several tasks that mirror our expert philosophy within the brightest means. In 2003 we developed the design and working drawings for reconstruction regarding the connection throughout the Volga River in Kimry city of Tver area. When it comes to time that is first Russia, strengthening for the existing prestressed strengthened tangible box deck had been implemented in the form 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 in place of crushed rock. It has permitted enhancing the connection capability as much as standard values and straightening the carriageway profile.
