微型钢管桩后注浆工艺在倾斜建筑加固中的应用

Application of Post-grouting Technology of Micro-steel Pipe Pile in Reinforcement of Inclined Building

某工程钢结构储尘罐建设在回填地层之上,由于回填土处理不当,周边地面下沉开裂严重,雨水顺裂缝下渗,导致基础发生不均匀沉降。文中结合工程实际,提出了具体治理方案,详细介绍了微型钢管桩后注浆在基础加固设计、施工中的关键节点,期望为类似工程提供借鉴。

A steel structure dust storage tank is built on the backfill ground. Due to improper backfill soil treatment, the surrounding ground sinks and cracks seriously, and the rainwater infiltrates along the cracks, resulting in uneven settlement of the foundation. Combined with the engineering practice, the concrete treatment scheme is given, and the key nodes in foundation reinforcement design and construction are introduced in detail, it is expected to provide reference for similar projects.
