摘　　要：古瓦水电站右岸溢洪洞斜井为斜井较深、坡度较大、截面不同的泄水建筑物。为攻克洞内钻孔灌浆施工工期紧张、施工风险高等问题,本文研究设计了一种升降台车,该台车具有安全系数高、结构稳定、能满足在斜井不同截面中自由升降的特点,保证了钻孔、灌浆施工的顺利完成。The inclined shaft of spillway tunnel on the right bank of GuWa hydropower station is a discharge structure with deep inclined shaft,large slope and different cross sections.In order to overcome the problems of tight construction period and high construction risk of drilling and grouting in the tunnel,a lifting trolley is specially designed.The trolley has high safety coefficient,stable structure,and meets the characteristics of free lifting in different sections of inclined shaft,so as to ensure the successful completion of the construction in drilling and grouting..
