Sheet Pile

SHEET PILE

Description

Steel sheet piles are manufactured in a variety of shapes and sizes with improved bearing properties.

Depending on the effective load, the retaining wall can only use steel sheet piles or combine the use of steel sheet piles with steel pipe piles (Steel Pipe Pile) or H-shaped steel piles (King Pile) to increase torque resistance, curling.

In terms of size, steel sheet piles have slab widths from 400mm to 750mm.

Using piles with large slab widths is usually more economical than piles with small slab widths because fewer piles are required if calculated on the same retaining wall length. Moreover, the reduction of the number of piles used also means saving time and cost for the downstroke stage, while reducing the amount of groundwater flowing through the lock grooves of the pile.

The length of the steel sheet pile can be fabricated up to 30m at the workshop, however the actual length of the pile is usually determined by the transport conditions (usually from 9 to 15m), only the box pile is machined at construction site can be up to 72m.

Advantages and disadvantages

Some outstanding advantages of steel sheet piles are as follows:

• Ability to withstand high dynamic stress (both during construction and during use)
• Ability to bear great force while the weight is quite small
• Steel sheet pile can be easily connected by welded joints or bolts to increase the length
• Steel sheet pile can be used many times, so it is economical.

The disadvantage of steel sheet piles is the calculation of corrosion in the working environment (when using steel sheet piles in permanent buildings). However, this disadvantage can now be completely overcome by protection methods such as anti-corrosion coating, galvanized coating, electrochemical corrosion resistance or you can use steel sheet piles made of solid steel. special anti-corrosion properties.

Application

With a high capacity to bear high loads, it is easy to see that steel sheet piles are suitable for port constructions, piers, dams, in addition to soil pressure, they also bear the impact of waves as well as the impact force of boats when paired, romantic. In addition to port works, many projects of embankments, canals, and flow improvements also use steel sheet piles due to their convenience, fast construction time, good durability.

With road works, traffic tunnels passing through some complicated steep hills or along the river bank, the use of steel sheet piles to stabilize the slope or make the embankment also proved quite effective.

In civil engineering, sheet piles can also be used as basement walls in multi-storey houses or in underground car parks instead of reinforced concrete walls.

The area where the Sheet Pile is most commonly used is as a barrier wall for soil or water when constructing temporary excavation pits.
