摘　　要：电站汽轮机轴承座二次灌浆质量影响汽轮机振动,特别是轴承座底板与二次灌浆层接触面的密实度对振动的影响最大。实际施工中,由于各种因素造成二次灌浆层质量问题时有发生,返工重做是最直接、最可靠的处理措施,但如何安全地把设备从二次灌浆层中分离取出一直是工程难题。介绍了采用二次灌浆层取芯隔离安全修复技术成功解决了工程难题。Second grouting quality of bearing pedestal influences on vibration of turbine in power station,especially density of interface on bottom slab and second grouting layer.During the construction,quality defect often happens because of some causes.The most direct and reliable measure is doing another.But safely taking off the equipment from second grouting layer is always difficult.In this article,coring separate repairing technology is adopted to solve the problem.
