提水灌溉工程混凝土建筑物的侵蚀及修复

Erosion and repair of concrete buildings of water pumping irrigation works

通过对甘肃景泰川和宁夏固海工程等提灌工程混凝土建筑物受高矿化度地下水侵蚀破坏的原因分析,按照减少侵蚀介质和提高混凝土抗侵蚀性的思路,提出了黄土高原地区的提水灌溉工程混凝土建筑物的修复技术,并取得了良好的修复效果.

Analysis on erosion factors of the concrete buildings of water pumping irrigation works in Jingtaichuan （Gansu） and Guhai （Ningxia） subject to highly mineralized groundwater is carried out. For reducing erosion medium and increasing concrete＇s anti-erosion quality, a repair technique for the concrete buildings of water pumping irrigation works in Loess Plateau area is presented, and good repair effects are obtained.
