摘要
冶勒水电站防渗墙施工廊道位于深厚覆盖层中,为城门洞形,断面尺寸为6000min×6500mm,由于开挖断面大且受防渗墙施工的干扰,施工难度和安全隐患大,所以按"短进尺、弱爆破、强支护"原则开挖,减少了资源的投入,防止了塌方的发生,保证了开挖和混凝土衬砌质理并加快了施工进度。
The construction gallery for anti-leakage wall of Yele Hydropower Station is located in a deep overburden layer, with a shape of city gate (section: 6 000 mm×6 500 mm. Due to large excavation section and the molestation resulted from construction of anti-leakage wall, the construction difficulty and hidden safety troubles of such construction gallery are great, so the excavation is in accordance with the principle of short progress, weak blasting and strong support. Such measures reduce the dedications of resources, prevent the occurrence of collapse, ensure the quality of excavation and concrete lining, and expedite the construction schedule.
