The Primorsky Prospect Embankment

Россия, Санкт-Петербург
The Primorsky Prospect Embankment

River Barrier: Bolshaya Nevka River

Overall length: 2,727.4 m

Opened in: the middle of the 19th century – 1962

Embankment parameters

The Primorsky Prospect Embankment spreads along the right bank of the Bolshaya Nevka River from Ushakov Bridge to the 3rd Yelagin Bridge of Primorsky District of Saint-Petersburg.

The embankment has a pile foundation of reinforced concrete sheet piling and piles with hanging blocks of the low wall. Some sections have granite-facing blocks. The embankment downstream the 3rd Yelagin Bridge is hardly reinforced.

Embankment history

The Bolshaya Nevka River bank reinforcement was started after permanent Ushakov Bridge completion. The embankment had a gentle green slope with a wooden fastening near the slope foot.

In 1927-1928 the embankment slope was strengthened with a stone paving from Stroganov (currently, Ushakov) Bridge to Academic Shimanovsky street (about 680 m). The bank line was aligned mainly by moving to the river that required filling with ground. At the slope foot a retaining wall was arranged with soldier piles anchored into soil mass. Along the embankment the tram route was laid with U-turn against Academic Shimanovsky Street, so here the embankment was curved projecting into the river (69.5 m from facade) to arrange a tram circle. Here the bank was reinforced with a low concrete cordon on the pile foundation consisting of two rows of vertical wooden piles with a curved slope paved with grout-based rugged stones. The site was fenced with railing with bollards.

Due to Ushakov Bridge re-building the adjacent downstream part of the embankment (100 m) was again re-built. Red line of the embankment changes its position again and moves to the river that requires filling with ground. The embankment structure is wooden sheet pile wall with soldier piles. They are topped with laid-on boards or stone berm. The 67 m of wall near the bridge is anchored into natural soil mass by anchor wall with tie rods. On the slope ladders descending to water are arranged on rubble stone footing.

The next step of the embankment reinforcement started in 1962 at 240 m long section downstream the site. This section already has a pile foundation of reinforced concrete sheet piling and piles with hanging blocks of the low wall facing with granite.

All of the next embankment sections have approximately the same design as the wall built in 1962, but the blocks are not faced with granite though the upper granite cordon stone is installed.

The embankment downstream the 3rd Yelagin Bridge has not been completed. From the whole set of the construction works, the vertical reinforced concrete sheet piling was only installed but it does not protect the ground slope against erosion.
