大口径玻璃纤维增强混凝土管(FRPCP)曲线顶管工程的质量控制

摘要

该文介绍了玻璃纤维增强树脂混凝土管的管壁结构形式,针对凌桥工程曲线压力顶管确定管材的技术要求,同时通过添加玻璃钢丝改善管口处的压缩变形能力,降低顶进过程中应力集中造成管口破坏的可能性.提出了主要原材料的技术要求和生产过程监造技术要求.%Wall structure of FRPCP was introduced, the technical requirements of pressure pipe for curved jacking of Lingqiao project were stated. By adding glass fiber and GRP fiber, the compressive deformation was improved to reduce the possibility of failure of the pipe joint caused by stress concentrations. The technical requirements for raw materials and supervision of the production process are given.
