Pile Foundation Installation

There are two categories of pile installation system proposed for installing concrete-pile (RC-pile or PC-pile), i.e. dynamic impact system (well-known as impact hammer system) and static pressing system (well-known as hydraulic static system). The selection of pile installation system depends on the environmental concerns of the construction area. If the noise and vibration effects from pile driving are not an issue to the surrounding area, the impact hammer system is a preferable system for installing concrete-pile. However, if the control of noise and vibration disturbance in project site is an important matter, the hydraulic static piling system is the most appropriate piling technique to be proposed.

Impact Hammer System

The type of impact hammer system proposed for installing concrete-pile is diesel hammer (Dong-Fang diesel hammer or KangDa diesel hammer). Diesel hammer is one of the most practical way for installing concrete-pile because of its easy mobilization, easy operation and applicable for many project conditions. The quick installation method will ensure completion of work within the given time and the optimal rate of hammer impact energy produce an excellent accuracy of pile capacity. Diesel hammers are suitable for most types of ground, except very soft clays. They perform well in cohesive or very dense soil layers and work most efficiently when driving into stiff to hard clays.

Hydraulic static system

For many years, noise and vibration caused by pile driving was thought to be unavoidable problem. However, the introduction of Hydraulic Static Pile Driver (pile pressing machine) has made these problems a thing of the past. The hydraulic static piling system becomes a preferable alternative because of its advantages; (1) the most environmentally friendly piling system - the most minimal emission of noise, vibration and pollution during pile injection process, (2) possessing high level of operational accuracy and excellent piling quality, (3) measurable soil-pile resistance (load capacity of every pile is predictable).
