sheetpile / soldierpile wall

The system consists of a series of precast concrete sections connect together via T&G joints to yield a continuos wall.

The sheetpile wall serves generally to resist lateral earth pressure. The stability is derived from passive earth pressure mobilized in front the embedded toe of the wall. Additional support the wall, however is skillfully achieved though the development of a system of anchors, ties, struts placed at a higher level behind the wall.

DIFFERENCE BETWEEN PRECAST CONCRETE SHEETPILING AND CONVENTIONAL STEEL SHEETPILING

CONVENTIONAL STEEL SHEETPILING PRECAST CONCRETE SHEETPILING
Flimsy, possibility of buckling within thin section > Robust with rigid concrete section in special profiles
Corrosion, vulnerable to exposure conditions > Special cement and thicker concrete cover
Protective coating: not practical and costly > Inherent durable properties of concrete
Short lifespan, high maintenance costs > Maintenance free with concrete structure
Escalating costs of steel > Stable price, less affected by price fluctuation

types

Two series of precast sheetpiles are designed to cater for various application in different site conditions.

ST Series

> Suitable for softclayey/ silty or loose sandy soils.

LS Series

> Suitable for medium stiff/ medium dense sandy soils.


Application

1. DEVELOPMENT PROJECT :

  • BUILDING PLATFORM
  • EARTH RETENTION
  • SLOPE PROTECTION

2. CURVERT / BANK STABILIZATION

  • DRAIN
  • POND
  • RIVER
  • CANAL
  • LAKE

3. MARINE STRUCTURE

  • WHARF
  • JETTY
  • COASTAL PROTECTION

4. ROADWORK / RAILWAY / HIGHWAY CONSTRUCTION

  • EMBANKMENT
  • BRIDGE
  • ABUTMENT
  • WINGWALL

advantages

1. Space Saving

  • The precast sheetpile method of construction alleviates site constraint problem that might arise during installation and / or at time of service

2. Robustness

  • Right section with in built ribbed or corrugated profiles will facilitate driving and handling process

3. Cost Effective

  • Efficient wall section designed significantly minimises foundation cost

4. Corrosion Free

  • Being corrosion free it will entail no treatment cost
