TBT Piling (Sabah) Sdn Bhd utilises the imported ZYC injection system as an alternative modern method for the installation of both reinforced concrete piles and prestressed spun concrete piles, conducted in accordance with BS EN 12699:2001 Execution of special geotechnical work – Displacement piles’.
The machinery comprises an innovative hydraulic injection piling system which operates with limited noise, vibration and pollution. It allows for a smooth, simple and rapid pile installation process whilst adhering to the most stringent environmental protection requirements. It is generally economically comparable with the conventional hammer piling method, and is a more suitable method when piling adjacent to sensitive structures, or in urban areas where a clean, noise-free and vibration free piling system is essential.
The operation of machinery and system is suitably adjustable to allow piles to be positioned and installed with a high level of accuracy. Final setting of the piles is conducted by a cyclic loading procedure to ensure that the required bearing resistance by the surrounding soil has been achieved, thereby conducting a quality check through effectively load testing each individual pile upon completion of installation.
The machinery may be readily manoeuvred around site, and with its wide base and low centre of gravity it is suitable for most stable working platform conditions. It is easily dismantled for transportation and is generally of low maintenance.
Current available injection machinery consists of 120, 320 and 800 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).
