The specialists of JSC Lengiprotrans develop the design and working documentation for the construction of artificial structures of standard and individual design for skipping railways through various types of obstacles.
Structures of structures are developed taking into account complex hydrometeorological, geological, topographical conditions, including in earthquake-prone areas and in permafrost conditions.
In the composition of the works:
- bridges and overpasses using standard structures of reinforced concrete spans from 3.0 m to 34.0 m in length with ballast and metal spans from 18 m to 110 m in length with ballast or ballast plates;
- supports of the individual design on different types of foundation (piling piles, bored pillars, shallow deposits);
- individual ferro-concrete and metal span structures for various types of loads, including the rolling stock of high-speed traffic;
- tunnel overpass for passing under the embankment of railway tracks and highways using reinforced concrete and metal corrugated constructions of individual design
The documentation is developed in strict accordance with the current design standards, using specialized software that allows you to solve complex problems with high quality and in a short time.
The railway bridge across the Slavyanka River was projected on a new line Losevo — Kamennogorsk according to the scheme of 3x18.8 m with a total length of 66.6 m. Span structures are taken by metal girders with a ride on the bezblasted bridge cloth according to the standard project 981R. Intermediate supports of monolithic reinforced concrete individual design on a pile foundation of bored pillars with a diameter of 1.5 m.
The railway bridge across the Vuoksa River was designed on the new line Losevo — Kamennogorsk according to the scheme 23+88+33.6 m with a total length of 157.98 m. Intermediate supports made of monolithic reinforced concrete of individual design on the basis of drilling piles.
The railway overpass was designed at the Luzhskaya — Sortirovochnaya station to pass the railway loop and the fire road according to the scheme 1x16.5 m, the total length of 19.62 m. The span structure of the reinforced concrete slab is adopted according to the standard project of the series 3.501.146 with a broadened ballast trough. Supports from a monolithic reinforced concrete individual design.
The railway bridge on the pc410 was designed on the Vyborg — Kammenogorsk line according to the scheme 1x34.2, with a total length of 45.6 m. A metal span structure with a total length of 34.2 m beam type with a ride on the ballast of the individual design of JSC Lengiprotrans. Supports of monolithic reinforced concrete individual design on the basis of driven piles.
