BS 5911-1-2002+A2-2010 混凝土管和辅助混凝土制品.具有软接头的未加筋和加筋混凝土管(包括套管)和管配件规范(对BS EN 1916-2002标准的补充)
Concrete pipes and ancillary concrete products - Specification for unreinforced and reinforced concrete pipes (including jacking pipes) and fittings with flexible joints (complementary to BS EN 1916:2002)
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 “jacking pipes”) intended to be installed by pipe jacking,
microtunnelling or other trenchless technology.
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.
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 5911-100. However, these products
are now manufactured in the United Kingdom and so they have been included in this part of BS 5911.
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 1295-1 and BS EN 1610 deal with the planning,
design, installation and testing of drains and sewers. The Pipe Jacking Association’s “Guide to best practice
for the installation of pipe jacks and microtunnels” [3] is a source of advice on the use of jacking pipes.
