Variety of options to suit even the most load-heavy project needs.
What kind of strutting system does your project need?
As a general rule of thumb, shorter strut lengths will benefit from beams as there are more connection possibilities, the ability to support vertical alongside easier installation; while pipes are more suited to longer strut lengths as they require less intermediate support by the primary kingpost and save a significant amount of weight. Of course, there will be necessary exceptions to this generalisation, including the possibility of utilising tie-rods instead.
By excluding soil and/or water from the excavation work happening below, strutting systems act as the silent guardians, the watchful protectors in ensuring that the stability of retaining walls are not compromised for particularly demanding retaining wall loads. OSP can specifically provide either beam or pipe struts, opening up a wide variety of options to suit even the most load-heavy project needs.
The design of our strutting systems are rooted in OSP’s grounded understanding of the relationship between soil and structure interaction. Strutting systems are the preferred option when it comes to land excavation related projects, being the better solution for potential soil movement and waving mid- project, caused by certain soft soil conditions.
Excavation with Struts
Sheet pile is driven to the required depth, as per project design and OSP technical support.
Excavation of soil begins until intended depth level of first strut, stopping slightly below the depth.
Installation for first level of struts then begins, including a combination of the waler, stiffener, main strut, bracing and leg as per project design.
Process repeats continuously until the desired amount of struts has been achieved.
Construction of the permanent structure begins at the lowest strutting level, with a gap left between the sheet piles and the permanent structure for safe removal of sheet piles after.
This continues, while simultaneously removing strutting levels and finally extracting the temporary sheet piling once work is completed.
Riverpark Residence, Vietnam
• Construction of 2-level basements in 3 separate blocks, with buildings spanning 13, 16 and 24 storeys respectively.
• Supplied and install bracing systems for temporary underground excavation.
Underground Water Reservation Tank at Soi Suksawat 43, Thailand
• Deployed a hydraulic vibrodrive to install temporary sheet piles.
• Strutting and waling system subsequently installed for additional support.
West-East Highway Project, Vietnam
• Development of infrastructure for 6 resettlement sites
• After efficiently providing our services, facilitated smooth resettlement of more than 7000 households and organisations previously affected
• Supported contractors on temporary works for underground excavation
Further combinations of various components can be used to support the main retaining wall and anchorage system installed. Walings are in this way a great example of distributing the structural loading from props and anchorage systems to the sheet pile retaining wall.
