UPDATED PIPE AND PORTAL-CULVERT HANDBOOK FOR ENGINEERS AND SPECIFIERS

Artcile Date: 29 January 2010

The Concrete Manufacturers Association’s (CMA) P.I.P.E.S. (Concrete Pipe, Infrastructural Products and Engineering Solutions) Division has issued an updated version of its ‘Precast Concrete Pipe and Portal Culvert handbook’. Revised by independent pipes consultant, Alaster Goyns, it is accessible in hardcopy, CD, or through the CMA’s website.

Aimed at designers and specifiers working for municipal and consulting engineers, the handbook provides the basic guidelines on correct usage, selection and specification of concrete pipes and culverts. Installers will also find it useful.

CMA director, John Cairns, says the handbook mainly covers pre-construction and design aspects including the basic theory on determining product size, strength and durability, as well as some theory on special features. Chapter headings include product classification, hydraulics, loads on buried pipelines, concrete pipe strengths, bedding, pipe jointing, floatation, sewer corrosion, portal culvert strengths and field testing.

The formulae, diagrams and tables provided are adequate for most product applications. However, they are ...Read More

CONCRETE PIPELINES BOOST CAPACITY IN TSHWANE’S PIENAARS RIVER OUTFALL SEWER SYSTEM

Artcile Date: 19 June 2007

In a R74 million upgrading project, the Pienaars River Sewer-Section Mamelodi in north-eastern Tshwane (Pretoria) is being boosted with the construction of a sewer tunnel and an additional pipeline, all of it concrete. The main contractor consortium, Cerimele- Phenduka Joint Venture, began working on the project in June 2005 and will have it completed by the end of August this year.

Johann Wessels, Deputy Manager: Replacement and Upgrading of the Tshwane Metropolitan Council’s Water and Sanitation Division, says the system will relieve the old pipeline which drains the rapid developing Kungwini-west area and residential areas such as Waltloo, Nelmapius, Wilgers, Mamelodi and Silver Lakes.

“The new project consists of two pipeline sections covering a combined distance of some 3.4km, a 770m long tunnel and two bridges, with a combined length of over 100 meters, spanning the Pienaars River. Initially the new pipeline sections will be linked through an existing line in ...Read More
