设备基础是设备安全运行的先决条件,基础在设备的长期运行中也同样受到疲劳损坏或意外损坏,如不及时处理势必酿成事故.设备基础一般都是钢筋混凝土结构,如重新制作费工费时影响生产.我厂在基础损坏时采用了一些快速处理法,收到了较好的效果.基础长期受冲击载荷的影响,达到疲劳的极限属于正常损坏,一般能做到有计划的修整;另一种事故性的属于无法预见的损坏.我厂的事故损坏一般有:基础底层地质结构的变化造成基础下沉或整体基础移动;基础遭受剪切力过大,造成地脚螺栓断裂;基础施工在二次灌浆时与母基础结合不牢,造成松动.现介绍两起快速修复的实例:1.二次灌浆与母基础脱离或基础中间因受超极限剪切力造成断裂的快速处理.
The basis of equipment is a prerequisite for the safe operation of the equipment. The foundation is also subject to fatigue damage or accidental damage in the long-term operation of the equipment. Failure to deal with it in time will inevitably lead to accidents. Equipment foundations are generally reinforced concrete structures, such as the re-production of labor costs Influencing production. Our factory adopts some quick processing methods when the foundation is damaged, and has received good results. The foundation is affected by the impact load for a long time. The limit of fatigue is normal damage, and generally it can be planned and trimmed; This kind of accident belongs to unforeseen damage. Our factory’s accident damage is generally as follows: the underlying ground geological structure changes to cause the foundation to sink or the overall foundation moves; the foundation suffers from excessive shear force, which causes the anchor bolt to break; the foundation construction is During the secondary grouting, it is loosely combined with the mother foundation. This is an example of two rapid repairs: 1. Rapid processing of secondary grouting and mother base detachment or fracture due to shear stress at the extreme limit.
