Analysis of the leakage in the underground workshop of Xianghongdian Pumped Storage Station

The underground workshop of Xianghongdian Pumped Storage Station became damp due to the leakage near the concrete sidewall on the upstream of the workshop after the main inlet was supplied with water,which did great harm to the proper usage of the machinery and power-generating equipment and the personal health. Based on the detailed investigation and surveying on the spot,the causes of the leakage are analyzed,and some countermeasures are suggested,such as concentrating drainage in the workshop and blocking the leakage passage on the outside of the workshop. By means of the treatment,the dampness has been improved obviously and the wall is dry on the whole.
