Box Jacking Services for Rail, Road & Infrastructure Crossings
The box jacking technique is widely used where surface disruption must be minimised and environmental impact carefully controlled. As a trenchless construction method, Box Jacking is particularly suited to projects in sensitive environmental areas or locations where traffic and rail operations must remain fully operational, including road and railway underpasses, box culverts and drainage structures, pedestrian and utility tunnels, and infrastructure crossings beneath embankments.
Design and Engineering
Every Box Jacking project is unique. The shape, size, and structural requirements of each box vary depending on site conditions, loading requirements, and ground characteristics. For this reason, the design stage is critical to ensure safety, durability, and precision during installation. We provide a fully integrated service, including:
Key Consultancy Services
Design inputs should include settlement assessment, jacking forces, temporary works, shield design and construction sequencing.
Design and Fabrication of Bespoke Tunnelling Shields
Bespoke shields are designed to suit box geometry, ground conditions, jacking loads and the required installation methodology.
Development of Anti-drag and Friction-reduction Systems
Ground Settlement and Structural Design Calculations
Settlement and structural calculations are developed to manage risk to railways, roads, utilities, embankments and adjacent structures.
Installation of Custom-built Tunnel and Culvert Structures
HBT can support both design and construction of custom box structures, including installation planning, temporary works and jacking operations.
