泵送混凝土洗、润管预防堵管技术

Technology of preventing pipe plugging by pumping concrete washing and piping

以某水电站输水隧洞的12条泵送管道的洗管、润管工艺为研究对象,总结了泵送混凝土前后分别进行的润管与洗管技术、洗管、润管的经验。从泵送混凝土过程中润管、洗管过程中出现的堵管问题,或由于润、洗管不当导致的堵管问题出发,研究了其中的原因,更新了润、洗管技术,并作出详细说明,为今后润、洗管施工起到重要的参考价值。

To the water conveyance tunnel of 12 pipe line pu mping wash pipe and tube process as the research object,summarizes the respectively before and after the pumping concrete to embellish pipe and washing technology, the experience of the wash pipe and pipe. This article from the process of pumping concrete pipe, washing pipe in the process of plugging problems, or caused by improper Yu Run, wash pipe wall tube problems, studied the reason and updated the embellish, wash pipe technology, and made a detailed instructions. It is of great reference value for the future construction of washing and washing pipes.
