摘要
采取后张法预应力施工对管道压浆的质量有着严格的要求。阐述了预应力筋孔道压浆对浆液材料、设备的性能要求,介绍了压浆施工常用的普通压力压浆和真空压力压浆两种施工工艺,归纳了预应力压浆的施工质量控制要点,旨在施工全过程中控制压浆质量。
Post tensioned prestressing construction has strict requirements for the quality of duct grouting.This paper expounds the performance requirements of slurry materials and equipment for prestressed reinforcement duct grouting,introduces two construction processes commonly used in duct grouting construction,that is,the ordinary pressure grouting and vacuum pressure grouting,and finally sums up the construction quality control points of prestressed grouting so as to control the grouting quality in the whole construction process.
