Excavation Strutting Systems in Indonesia

ESC provides steel strutting systems for excavation support, sheet pile walls, and retaining structures requiring internal bracing. Strutting systems provide temporary structural support during excavation, helping the retaining wall resist lateral loads while construction progresses.

ESC strutting solutions can incorporate steel struts, walers, connection components, and custom-fabricated steelwork, with configurations developed according to project-specific structural and site requirements.

Project Case Studies

What Is an Excavation Strutting System

An excavation strutting system is an internal bracing system used to support retaining walls during excavation. Steel struts span between opposing sides of the excavation, while walers help distribute loads along the retaining wall.

Strutting systems can be used where external anchoring is impractical or where the excavation design requires an internally braced support system.

They are commonly integrated with sheet pile retaining systems and other temporary retaining structures for civil engineering and infrastructure works.

Strutting systems can be utilises in a variety of applications which include: basement excavation, cofferdams, and various deep excavations. ESC can offer the following:

Steel Strutting Systems for Excavation Support

Every excavation presents different structural and site constraints. The required strutting arrangement therefore depends on factors such as the excavation dimensions and depth, retaining wall configuration, structural loads, site conditions, construction sequence, and available working space.

ESC can provide steel strutting components and supporting fabricated steelwork to meet project-specific requirements.

Strutting System Components:

Steel Struts

Steel struts form the primary compression members within an internally braced excavation. They transfer loads between opposing retaining walls and provide temporary support as excavation progresses.

Strut dimensions, spacing, levels, and connection arrangements should be determined according to the structural design and specific excavation requirements.

Waler Beams

Walers run along the retaining wall and help distribute loads between the wall and the steel struts. They form an important part of the overall excavation support system and provide connection points for the struts.

The required waler arrangement depends on the retaining wall system, structural loads, strut configuration, and project design.

Strut Connections

Connections transfer forces between the struts, walers, and retaining structure.

Connection details can be developed according to the structural arrangement, member sizes, loads, and installation requirements of the project.

How Do Strutting Systems Support Sheet Pile Walls?

Steel sheet pile walls can require additional structural support as excavation depth increases. An internal strutting system provides this support by transferring loads from the retaining wall through the walers and steel struts to the opposite side of the excavation.

This creates an internally braced excavation without relying solely on external anchoring.

The appropriate support arrangement depends on the sheet pile system, excavation geometry, soil and groundwater conditions, structural loads, and construction sequence. Final member sizes, spacing, connections, and strut levels should therefore be determined through project-specific engineering design.
