Utilities & Drainage
Analysis and design for utilities and drainage: manhole structures, pipe design, special structures, pressure mains and pipe jacking.
The structures in the network: everything that is more than a pipe in a trench.
What we take on
- Manholes and special structures, flow control and transfer chambers
- Pipe design for buried and exposed pipework
- Thrust blocks and restraint for pressure mains
- Verification for pipe jacking and trenchless methods
What governs the design
Cover, traffic load and bedding decide the choice of pipe; uplift decides the manhole construction in groundwater. For jacked pipes, jacking forces and intermediate jacking stations are added, which the pipe section has to take.
Temporary works are part of it
For trenches in built-up areas we design the support with it: trench support, underpinning of adjacent foundations and verification of settlement at the neighbouring building. See also deep excavations and retaining walls.
