摘要
在东北特钢厂旋流井施工中,分析了沉井下沉施工的弊端,结合施工现场实际情况进行了施工方案比较,采用了旋流井逆作法的施工技术。针对施工中存在的问题,成功地解决了在沿海地区、厂房内和岩石爆破施工,容易造成已有建筑物出现下沉的技术难题,确保了施工质量。
The author analyses the disadvantages of caisson sinking, compares construction plans in combination with actual situation and applies the construction technique of cyclone well reverse construction method during cyclone construction at Dongbei Special Steel Group. The technical difficulty that the existing building sinks at offshore area, within workshop and at rock blasting is successfully solved and the construction quality is ensured.
