Neither were we needed 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 preserve pavilions and memorial dishes on the draw period. But we considered renovation of this connection look as created by S. Kerbedza to be our expert responsibility and our responsibility as Petersburgers as well. And now 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 back its initial title.
The St. Petersburg World Club awarded Institute Stroyproekt an indication of Conformance for Blagoveschensky Bridge rehabilitation.
The reward that is same fond of Mostootryad 19 and Committee on State Control, utilize and Protection of Historical and Cultural Heritage. Nevertheless, in this specific instance the Committee merits are not obvious. In line with the Committee’s requirement the memorial dishes reading that the connection had been called after Lieutenant Schmidt, a hero for the revolution of 1905, and rebuilt in 1930s on the basis of the design by Peredery have now been preserved. We addressed towards the Committee showing why these plates misinform residents and visitors associated with populous town and asked for extra dishes become set up to say rehabilitation of 2006 – 2007. But, a refusal was received by us to your demand. But we do hope that justice may be finally offered. Though Blagoveschensky Bridge comes back us into the middle of XIX century its a contemporary framework wh ere the essential interesting technical solutions have now been realised. The bridge became one . 5 times wider (from 24 to 36 m wide) and ended up being redesigned for nowadays lots, but during the exact same time we been able to protect historical 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 maybe not by piers but by fixed decks. Such structure permitted attaining main bearing regarding the draw piers and eccentricity that is excluding.
Guss asphalt ended up being used 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 training after it turned out introduced by ABZ-1 Asphalt concrete plant which was the initial plant within our nation to perfect this technology that is german. Guss asphalt technology for connection building has fixed a lasting issue with all the connection flooring at draw spans and plate that is orthotropic.
European countries is put aside for the time being, why don’t we 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. Advanced achievements are often introduced in some 10– to our country 15-year delay. Nevertheless, the problem with composite strengthened concrete has progressed an additional means. As soon as we first applied composite concrete, cast-in-situ concrete had been nevertheless highly popular within the western and just during the change for the century they began changing to composite concrete. More over, 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 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 and only composite ones. As previously mentioned by well-known company that is french tpi, that is a consultant of our universities from Turkey and Italy, cast-in-situ concrete is known as antique when you look at 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.
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 twenty years ago at our very own danger has become commonly found in European countries: composite reinforced tangible proved to be more affordable, more desirable and sturdy.
In terms of strengthened tangible beams, unfortuitously numerous Russian areas nevertheless make use of them in connection construction. From our part we now have recommended GK Rosavtodor to change the look of standard reinforced tangible beams. Stroyproekt has discovered a typical and solution that is workable enables handling disadvantages of this present beam designs without re-equipment of manufacturing flowers. Our concept is accepted definitely and now we wish that the standard that is new design will likely to be developed and authorized.
The task of Western High Speed Diameter has grown to become a quintessence of our expert experience.
As a whole, the WHSD is a revolutionary task from different standpoints. This is the first expressway, that will link the southern and north borders 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. Included in this, the unique connection structures for the WHSD Central Section which will 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 very very long; its main period is 168 m very very long; the underclearance is 52 m); – A cable-stayed connection across Korabelny Fairway (the bridge is 620 m long; asian wife 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 central period is 220 m very long; the underclearance is 25 m).
The most important an element of the WHSD path runs through a narrow corridor across compact commercial areas. Insufficient free area ended up being probably the most pronounced during the part 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 part and in addition for many phase IV sections. Double deck trusses enable separating traffic that is opposite to your reduced and top deck correspondingly (supplying 4 lanes in a choice of traffic direction). Horizontally, the trusses are situated on an adjustable radius curve with superelevations and change areas, that will be really uncommon for dual deck structures. The longest period is 144 m.
The WHSD design includes other solutions that aren’t therefore large-scale yet still quite interesting. Including the toll plaza during the exit ramp to Automobilnaya Street (phase I) could be taken which was built on two amounts as a result of incredibly space-limited area. Aesthetically the WHSD path was developed in a uniform, recognisable and mode that is dynamic 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 a complete summary of all innovations introduced by Stroyproekt or just interesting tasks in the article that is single. However, i want to emphasize a few jobs that mirror our professional philosophy when you look at the brightest method. In 2003 we developed the design and dealing drawings for reconstruction of this connection throughout the Volga River in Kimry town of Tver area. For the time that is first Russia, strengthening for the current prestressed reinforced 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 as opposed to crushed rock. It has permitted increasing the connection ability as much as values that are standard straightening the carriageway profile.
