Sheet piles
The sheet pile walls are vertically nailed steel profiles, fastened to each other by means of a specially shaped lock on the element itself, which due to the friction during driving becomes watertight and provides monolithicity of the executed wall. This allows the use of this type of fortification even in large water inflows, as at a sufficient depth of driving the construction excavation is protected from the entry of groundwater.
The main principle in implementation is to reduce the friction between the sheet pile and the soil. The vibrations temporarily disturb the soil around the element, causing the effect of "liquefaction", which leads to a reduction in friction between soil and sheet piling. This allows the compaction to be done with very little added force, ie. own weight plus the weight of the vibrator or assistance from the mast.
Advantages
✓ Applicable to almost all types of soil
✓ An ideal option for strengthening in the presence of high groundwater, irrigated and swampy terrains, in which the excavation is unstable even for a short period of time
✓ Suitable for limited space: construction of a wing, close trenches and mines
✓ Possibility of fencing polygonal and circular perimeters
✓ For high loads, the possibility of combination with anchors and spanning structures
✓ High productivity
✓ Instant wearability
✓ Applicable in aquatic environment
✓ Inventory use of dowels
✓ Lack of excavation works to implement the strengthening
