Steel sheet piling is a manufactured edifice product with interlocks at both ends, closely fitted to form a continuous wall for sheet piling. The applications of steel sheet piles are characteristically designed to create an unbendable barricade for ground and water, while resisting the lateral pressures of those pliable forces. The capability of a sheet pile section to execute is dependent on the geometry and soils it's driven in.
Steel sheet piling is commonly used in two applications: permanent structures and temporary works.
Permanent sheet piles remain 'stay-in-place' in the ground as a permanent retaining structure. A temporary application is to offer a safe access to construction in a confined area. The sheet piles will be removed once work is completed.
The benefits of steel sheet piling are:
- Easy to handle, transporting and installation.
- Lightweight for transportation.
- Effective retaining wall with maximum bending moment.
- Flexible solutions.
- Recyclable and reusable.
- Suitable for deep excavation works such as waterfront structures, basement construction & underground car park, power plant construction, bridge, canalization & river rehabilitation work, water treatment plant, railway & tunnel works, highway construction; and general excavation for foundation works.
We make it our business at OSP to evaluate every facet of a proposed scheme; to assess the challenges and objectives of the installation – and to look beyond them through the human dimension.
Steel sheet piling is suitable for offshore construction as it is designed to cater for heavy vertical loads and large bending moments with fast execution. Few types of retaining structures in waterfront structures are ship berthing area, wharf, breakwater and slipway.
Steel sheet piling is used as the support, protection and beautification of river embankments. It can also function as flood protection wall during monsoon or high-tide season.
Steel sheet piling can be used for top down construction (permanent) or bottom up construction (temporary); both methods require minimal construction width offering significant time and cost savings. Steel sheet pile can also support vertical loads from the structure above.
As support structure for railway and tunnel construction, steel sheet piling helps to minimize excavation and disposal works, thus speed up the construction duration.
General excavation works involve temporary excavation for foundation construction and protection to underground structure, minimizing excavation volume and area.
Most of the time, steel sheet piles act as retaining structure for excavation works. They can be installed easily and extracted anytime when the construction work is completed. The steel sheet piles can then be re-used and carried forward for later construction stages.
Steel sheet piles can act as foundation and abutment of the bridge, requiring minimum space and construction time.
