TBT Piling (Sabah) Sdn Bhd possesses a wide range of Hydraulic Hammer Piling Rigs for the installation of both reinforced concrete piles and prestressed spun concrete piles, conducted by experienced resources in accordance with ‘BS EN 12699:2001 Execution of special geotechnical work – Displacement piles’.
The hammer piling rigs are generally simple to mobilise and assemble at site, and are normally ready to commence works almost immediately upon arrival at site. They are capable of performing pile installation works in the majority of stable working platform conditions, and are able to individually handle segmental piles of up to 12m in length, for both vertical and raked piling requirements.
Pile installation is normally conducted utilising the “Hiley” dynamic formula to determine the final SET of a pile, with proper consideration for depth of penetration, required bearing resistance of the soil combined with appropriate safety factor, temporary compression of materials, and driving stresses, and to ensure as far as practicable that the most suitable hammer weight and impact energy is adopted to satisfy pile installation requirements and minimise risk of damage to piles during the installation process.
Current available impact hammer machinery includes from 1.0 Tonne to 16.0 Tonne systems, with capabilities to install a broad range of RC piles (150mm sq to 450mm sq.) and spun piles (250mm ø to 800mm ø.).
