For DN 225 up to DN 1350 For DN 1500 up to DN 1800 / In-wall joint Perforated Pipes Marshalls CPM manufactures precast concrete perforated pipes up to 600mm diameter. The pipes are drilled whilst wet and the semi-dry nature of the concrete used in the manufacturing process leads to spalling on the inner and outer surfaces around the holes. This is cosmetic only and does not affect the integrity of the pipes for land drainage use. Perforated pipes comply with the Department of Transport Specification for Highway Works, which states the total area of drainage holes should not be less than...

Rocker Pipes / Butt Pipes Butt pipes and rocker pipes allow for any differential settlement between the manhole and the pipeline, with the spigot/ socket butt pipe being built into the manhole wall. A rocker pipe is then laid connecting the butt pipe to the incoming/ outgoing pipe run, thereby incorporating a flexible joint close to the manhole. Nominal Size Nominal Size Junctions Branches of 100mm upwards can be fitted into all pipe sizes. Branches can be made from drainage materials other than concrete and are normally fitted to both full and short length pipes to suit customer...

Naylor Clay Bend Rigidrain Coupling Hepworth Supersleve Uni-junction pipes should be laid and orientated so that the junction is made to one side of the pipe i.e. not from vertically above. Junctions are not designed for vertical surface compaction and need to be surrounded in concrete. Ovoid Flexible Jointed Pipes Marshalls CPM offers a range of concrete ovoid pipes including a flexible joint seal for use with both foul and surface water applications. The ovoid concrete pipe is produced and tested in accordance with the relevant provisions of BS EN1916/ BS5911-1 Class 150 including...

Marshalls CPM has developed an Off-Site solution for the requirement of installing a dry-flow channel into concrete flexible jointed pipes. The machine made one-piece solution is available in 1500mm diameter with channel options of 150mm, 225mm and 300mm. Benefits of the system include: ■ Removes the problem of confined space working. ■ Considerable reduction in on-site construction time. ■ Can reduce costs associated with in-situ construction by 50%. ■ Can reduce over-pumping costs by 15%. ■ Can be included as part of Off-Site Attentuation components. LONGITUDINAL SECTION

Precast concrete bends are manufactured by cutting pipes into two or three segments and joining them together at the required angle using an epoxy resin. Where specific angles, centre line lengths or radii are required, these must be specified at the time of order (specials made to order). Bends may not necessarily have the same load-bearing capacity as the pipes with which they are to be laid. It is therefore recommended that they should be surrounded by suitably designed in-situ concrete where significant load conditions have to be met, or where anchorage of the pipeline is required....

Instructions as to use: Please supply pipe diameter and invert levels only. Marshalls CPM will complete and return for customer approval. All dimensions except diameter ± 100mm All bends are manufactured to ± 4º Tolerance Please note: individual pieces (such as rockers and bends) need to be ordered individually as they do not come as a complete unit
