- 1 Scope 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 specified in BS EN 1916 for unreinforced and reinforced concrete pipes and fittings, with nominal sizes not exceeding DN 1500 for circular pipes with base and WN/HN 800/1200 for egg-shaped pipes. Requirements are also specified for reinforced concrete circular trench and jacking pipes with nominal sizes greater than DN 1750, but not exceeding DN 3000. This part of BS 5911 also covers circular pipes with base and egg-shaped pipes. Steel fibre concrete jacking pipes are not manufactured in the United Kingdom and so are excluded from this part of BS 5911. NOTE 1 The planning, design, installation and testing of drains and sewers are covered by BS EN 752, BS EN 1295‑1 and BS EN 1610. NOTE 2 The Pipe Jacking Association’s “Guide to best practice for the installation of pipe jacks and microtunnels” [1] is a source of advice on the use of jacking pipes. <...

如何防止聚氨酯保温管道滑动
应在管道两端设置两个大型钢筋混凝土桥墩和补偿器，以确保管道固定不发生变化。外固定是因为设置钢筋混凝土桥墩是必要的，所以施工覆盖范围大，投资大，有时施工周期长，所以在施工前加以注意。 第二，内滑动内固定工作钢管通过一定的结构形式固定在外保护管上，充分利用外保护管的强度和刚度，以及外保护管与土之间的摩擦，进一步使内管固定良好，钢筋混凝土结构不固定，可以节省钢筋混凝土桥墩的施工。...
钢筋保护层测定仪的用途
钢筋保护层测定仪用途：钢筋保护层测定仪是一种便携式无损检测仪器，可用于钢筋混凝土结构施工质量的检测，能够在混凝土表层测定钢筋位置，检测钢筋保护层厚度及钢筋直径；此外，也可以对混凝土结构内部的磁性体及导电体的位置进行检测，如墙壁内部电缆、水暖管道等，施工前的探测可以有效避免施工中对这些设施的损坏，减少意外的发生。...
