摘要:

介绍了预制拼装桥墩的技术特点和连接构造,通过工程实例进行了传统现浇桥墩、球墨铸铁钢套筒预制拼装桥墩和新型钢柱脚预制拼装桥墩的经济对比,结果表明,新型钢柱脚预制拼装墩柱的单柱施工工期相比于球墨铸铁灌浆钢套筒预制拼装桥墩缩短约 21.62%,相比于传统现浇桥墩单柱施工工期缩短约 60%;新型钢柱脚预制拼装墩柱的单柱施工成本相比于球墨铸铁灌浆钢套筒预制拼装桥墩降低约 12.25%,相比于传统现浇桥墩单柱降低约 14.55%.综合对比结果表明,新型钢柱脚预制拼装桥墩在工期和成本上具有显著优势。

This paper introduces the technical characteristics and connection construction of prefabricatedassembly piers. The economic comparison of traditional cast-in-place piers, ductile iron steel sleeveprefabricated assembly piers and new steel column foot prefabricated assembly piers is carried out throughengineering examples. The results show that the single column construction period of the new steelcolumn foot prefabricated assembly piers is about 21.62% shorter than that of the ductile iron steel sleeveprefabricated assembly piers, and about 60% shorter than that of the traditional cast-in-place piers. Thesingle column construction cost of the new steel column base prefabricated assembly pier-column is about12.25% lower than that of the nodular cast iron steel sleeve prefabricated assembly pier, and about14.55% lower than that of the traditional cast-in-place pier single column construction cost. Thecomprehensive comparison results show that the new steel column base prefabricated assembly bridge pierhas significant advantages in construction period and cost.
