摘要
针对皮带机混凝土平台通廊存在裂缝隐患且裂缝仍有扩展趋势的问题,分析出其产生的原因为混凝土平台基柱柱基不均匀沉降。造成该平台基柱不均匀沉降的是设计和使用原因。制定出托换柱基法的治理方案,用灌注桩基托替换原天然地基独立基础。实践证明该措施消除了安全隐患,保证了设备正常运行,取得了良好的治理效果。
Cracks appeared at the passage of belt conveyer concrete platform and had a tendency of expanding.Analysis found that uneven sedimentation of platform pillar due to design and utilization was the reason.A solution was formulated to use filling pile base to substitute original natural individual foundation.The hidden trouble to safety was eliminated and equipment normal running ensured.Good treatment effect was achieved.
