地下厂房岩锚梁施工质量控制

宝泉抽水蓄能电站地下厂房岩锚梁是土建施工中的重中之重,岩锚梁及桥机运行的全部荷载,通过锚杆及混凝土与岩壁接触面上的摩擦力传到岩体上,充分利用厂房围岩自稳承载能力。岩锚梁是一种悬臂梁结构,因此施工中对岩壁成形、锚杆施工和混凝土浇筑等关键工序进行了严格的质量控制,并取得了良好的效果。

Quality Control Over Rock Anchor Beam Construction In Underground Power Station

Out of the construction of Baoquan Pumped Storage Power Station project,engineering over the underground power plant is of utmost importance.All load from rock anchor beams and operational crane spread into rock mass through the friction force resulting from the contact surfaces between anchor bars and concrete and rock wall.Thus,bearing capacity from the stable rock mass around inside the underground power plant is fully utilized.Due to the fact that rock anchor beam is a sort of socle beam structure,the importance of the formation of rock wall,placement of anchor bar and concrete placement,etc must be specially noted and the procedures must be strictly controlled in the whole process of construction.All above was well controlled and excellent results are achieved.
