CONCRETE DRAINAGE 116

Concrete DrainageCircular concrete pipes are available in an extensive range from DN 300 to DN 2400 with a full range of fittings including bends, fixedbranch and universal junctions, rocker and butt pipes.

Pipes are available with rolling ring (RR) joint for DN 300-1800 andsliding gasket (SG) joint for DN 2000-2400. Captive gasket (CG) jointis available dependent upon contractor preferences.

CG joint pipes are being phased in over a period of time, customersare advised to check availability.

• RR joint pipes employ a unique Delta gasket which, compared to a circular gasket, requires lower jointing forces and offers increased resistance to withdrawal after jointing.

• CG joint pipes employ a captive gasket cast into the pipe socket.

• SG joint pipes employ a sliding gasket fitted onto the pipe spigot.

• Gaskets are manufactured in SBR or EPDM and comply with BS EN 681-1.

• Nitrile gaskets are available for RR joint pipes upon request.

• Pipes will not join to other manufacturer’s cast or spun pipes.

• Pipes with RR joint can be jointed to CG joint pipes by using a change pipe.

• Pipes are vertically cast using vibration to compact a semi-dry concrete mix into the mould.

• Actual bore sizes available on request.

An alternative to full length fixed branch junction pipes, the universal junction provides users with 3 major benefits:

Easier InstallationQuick push and twist installation of the branch pipe into the universal junction seal. Easier to transport, handle and install because of its shorter length and reduced weight. Allows more flexibility when positioning the branch along the pipeline.

Increased Damage ResistanceNo more damage to fixed branches during storage, handling and installation. No more branchintrusion into the main pipe during on-site branching. The flexible universal junction seal allows forsome ground movement.

Greater FlexibilitySuperSleve DN 150 clay branches fit directly. Densleeve DN 150 clay branches and branches inother materials can be fitted with a suitable adaptor. The universal junction seal can accommodateeither straight pipes or a full range of fittings. Branch pipes may be deflected up to 3% without lossof watertightness of the joint.

The universal junction is made in accordance with, and the unit is tested for watertightness to, BS EN 1916.

Plastic caps are available to protect and blank off the universal junction seal.

Universal junctions are not designed as load bearing structures and should be encased in a suitably designed in-situ concrete surround.

Prevent axial loading of the seal by not connecting vertically or near vertically into the universal junction.

Manhole Jointing CompoundManholes are designed and manufactured to provide accurate joint profiles with a highquality finish. When used in conjunction with flexible jointing compound to BS EN 476, contractors can construct watertight manholes quickly, without the need for concrete surround. This method of construction is specifically endorsed by BS EN 752 Drains andsewer systems outside buildings 1997, BS EN 1610 Construction and testing of drains and sewers 1998, Civil Engineering specification for the water industry 6th edition 2004, The Building Regulations 2005, The Building Standards (Scotland) Regulations 2004 andDfT Specification for the Highway Works 2004. The use of the precast concrete productswith flexible jointing compound also meets the requirements of WRc Sewers for Adoption(5th edition).

To complement reinforcement materials EH Smith are able to provide a full range of ancillary products such as spacer, deckchairs, dowels, sleeves, caps etc. All of which arenormally associated with reinforcement installation.
