1 概况十三陵抽水蓄能电站发电机厂房建于蟒山体内,高压电缆需经出线竖井转出地面到出线场,完成发电输出过程。出线竖井总高度173.75m(▽45～▽218.75),其中预制件安装层深159m。出线井为圆形断面,开挖直径8.6m。采用滑模衬砌后内径7.3m。因为出线竖井是地下厂房垂直安全出口之一,所以竖井底▽45层与交通洞相连,顶部▽209层与出线洞相通,中间部分是载重量1t的电梯井,两侧为步行预制楼梯踏步板,四
1 Overview Shisanling pumped storage power station generator plant built in the Mangshan body, high-voltage cable to be out of the shaft out of the ground to the outlet field to complete the power generation output process. The total height of the outlet shaft is 173.75m (▽ 45 ~ ▽ 218.75), in which the depth of prefabricated installation is 159m. Outlet wells for the circular cross-section, excavation diameter of 8.6m. After using sliding lining diameter 7.3m. Because the outlet shaft is one of the vertical safety exit of the underground powerhouse, the 45th floor of the shaft bottom is connected with the traffic tunnel, the top ▽ 209 layer is communicated with the outlet hole, and the middle part is an elevator shaft with a load of 1t, and both sides are walking prefabricated stair treads ,four
