锦屏水电站高压线塔基边坡处理施工

Construction of side- slope treatment of high- voltage line tower base of Jinping Hydropower Station

锦屏水电站锦~右35 k V高压出线终端塔基所在的山坡下部因基岩裸露、覆盖层结构疏松,在雨季暴雨作用下,坡体出现裂缝并滑动,危及塔基安全,须进行处理。为此,采取了以下综合治理措施,即锚喷支护、系统锚杆、挂网喷混凝土、格构梁、锚筋桩、锚索加固等。详细介绍了施工方法。综合治理后,塔基边坡的稳定性得到了提高。

The bed rock in the lower part of the slope where the tower base of 35 kV high - voltage line at the right of Jinping Hydropower Station is located is bare and the covering layer is loose. The cracks exist in the slope body and the slope slides under the storm, which threatens the safety of the tower base, and must be treated. Therefore, the measures of shotcrete and rock bolt support, systematic anchor rods, mesh sprayed concrete, lattice beam, anchor pile, anchor cable reinforcement etc. were adopted. A detailed introduction to the construction method is given. The stability of the tower base was improved after the treatment.
