Circular Shaft Construction
Circular Shafts are a specialized underground construction solution widely used in the UAE for lift pits, pump stations, utility shafts, manholes, access shafts, and deep underground structures.
At APCC, circular shaft construction is executed to provide safe, precise, and structurally sound vertical excavations for infrastructure and building projects across Dubai, Abu Dhabi, and the wider UAE.
Circular shafts are particularly suitable for projects requiring deep vertical access, high structural integrity, and effective groundwater control, especially in confined or urban environments.How Circular Shafts Are Constructed
Circular shafts are typically constructed using sequential excavation and lining methods, designed to maintain ground stability and ensure safety throughout construction.Excavation and Support
APCC carries out shaft excavation in controlled stages using mechanical excavation methods. Depending on ground conditions and depth, temporary or permanent support systems are installed, including:
Secant pile or contiguous pile walls
Shotcrete lining
Precast or in-situ reinforced concrete rings
Steel liner platesThese systems prevent soil collapse and control groundwater ingress during excavation.Structural Lining and Finishing
Once the required depth is achieved, a permanent reinforced concrete lining is constructed to provide long-term structural stability. Waterproofing systems may be applied as required to meet project specifications and durability requirements.
Advantages of Circular Shafts in the UAE
Ideal for deep vertical access structures
High structural efficiency due to circular geometry
Effective groundwater control
Suitable for confined and urban sites
Can be integrated with other foundation systems
