水泥砂浆防腐衬砌管道出现空鼓问题浅析与预防

Discuss on Cavitation Erosion of Cement Mortar Lining Pipeline and the Prevention Measures

近年来城市缺水问题日益严重,引水工程在国内如雨后春笋般出现,引水工程平原地区主要采用管道进行输水,为使地下管道有较长的寿命,在使用年限内不被腐蚀,管道防腐问题显得尤为重要,在管道防腐过程中采用混凝土进行衬砌更为普遍,而衬砌过程中出现空鼓问题比较突出。主要对管道混凝土衬砌过程中出现的空鼓问题进行分析,以及采取的主要措施进行阐述。

Recently, cities are faced with severe water shortage problems,water diversion works were constructed for domestic and industries water supply. The steel pipes were used for water diversion works on plain area. The underground conduits were usually lined with concrete in order to prevent from corrosion. The problems caused by cavitation erosion were expounded in the paper, based on the analysis some countermeasures were put forward.
