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.
现场把热电缆绑扎在主筋侧面,从桩底至桩顶,桩顶外伸部分的接头外接数据采集盒。 TIP检测结果通过24小时测试到的温度数据,绘制桩身各深度幅值温度分布图,可以看出:该试验桩水泥水化热没有发挥好,桩身温度未明显升高(初始温度19˚C,最大温度仅24˚C)。原因可能是低质量的混凝土配合比造成的。对应于2.0m、5.5m和底部有异常,温度急剧下降。...
近年来,FRP筋及预应力FRP筋混凝土结构成为发展超耐久性工程结构的主要趋势。 在北美、北欧等西方国家,由于冬季的除冰盐对桥梁结构中钢筋腐蚀所带来的严重危害已成为困扰基础设施工程的主要问题,FRP配筋和FRP预应力筋混凝土结构的研究和应用发展较早且较快,并且有大量的产品。...
