Diaphragm Wall
A diaphragm wall is the structurally strongest method for any size or depth of retaining wall. Rectangular panels are excavated and backfilled with reinforcement cages and/or concrete.
Any shape of wall can be constructed by combining primary and secondary panels. Diaphragm walls can also act as cut-off walls during deep penetration into an impermeable soil layer. With this method walls with a thickness of up to 1.20 m and a depth exceeding 50m can be built.
Advantages:
- Less noise & less vibration - Noise pollution is prevented as the noise and vibration produced by the crane is very minimal.
- Strength of the wall - Prevents the collapse of excavated surfaces due to high lateral pressure induced by nearby structures.
- Excellent waterproofing - Can be used in the construction of diaphragm wall of a dam because a over cutting joint is possible without changing the underground water level.
- Flexibility of the wall - There is no limit to design of the thickness of the wall and the amount of steel reinforcement.
- Applicable to any ground conditions - The wide range of construction application from silt to rock.
- Accuracy in installation - Vertical accuracy is controlled within the range of 1.2% due to onboard computer.
