BS EN 1916 specifies requirements and describes test methods for precast concrete pipes and fittings, unreinforced, steel fibre and reinforced, with flexible joints and nominal sizes not exceeding DN 1750 or WN\/HN 1200\/1800, for which the main intended use is the conveyance of sewage, rainwater and surface water under gravity or occasionally at low head of pressure in pipelines that are generally buried. The scope includes pipes (collectively referred to as \u201cjacking pipes\u201d) intended to be installed by pipe jacking, microtunnelling or other trenchless technology.<\/p>\n
This part of BS 5911 specifies complementary requirements to those in BS EN 1916 for unreinforced and reinforced concrete pipes and fittings, as provided for in that European Standard, with nominal sizes not exceeding DN 1500 for circular pipes with base and WN\/HN 800\/1200 for egg-shaped pipes. Full requirements for reinforced concrete circular trench and jacking pipes with nominal sizes greater than DN 1750, but not exceeding DN 3000, are also specified.<\/p>\n
In addition to pipes and fittings having a circular cross-section, BS EN 1916 also covers circular pipes with base and egg-shaped pipes, neither of which are within the scope of BS 5911\u2011100. However, these products are now manufactured in the United Kingdom and so they have been included in this part of BS 5911.<\/p>\n
Steel fibre concrete jacking pipes are not manufactured in the United Kingdom and so are excluded from this part of BS 5911. BS EN 752 , BS EN 1295\u20111 and BS EN 1610 deal with the planning, design, installation and testing of drains and sewers. The Pipe Jacking Association\u2019s \u201cGuide to best practice for the installation of pipe jacks and microtunnels\u201d [3] is a source of advice on the use of jacking pipes.<\/p>\n
Contains requirements from BS 5911-100 and BS 5911-120 that could not be agreed upon for inclusion in BS EN 1916.<\/p>\n
