磁铁矿采空区处理施工工艺与技术方法探讨

Research on construction technology and technical methods of treatment for magnetite gob area

文章系统地介绍了采用地质钻机成孔,高压注浆机进行充填注浆的施工方法。为了将水泥砂浆及水泥粉煤灰浆填入采空区,采用能施加高压的输送泵及高压注浆设备、铸铁注浆管、水泥封孔的注浆工艺处理采空区铁路路基。在信息化施工过程中,通过试验不断地调整设计方法、改进施工工艺,在处理巨型磁铁矿采空区工程实践中达到了预期的目标。施工中,在控制充填边界、封孔方法及施工工艺等方面有一定的创新。提出的采空区施工技术控制、质量检测与评价方法,对同类工程勘察、设计及施工具有一定的参考价值。

The drilling methods with geology borer,backfilling and grouting through high pressure grouting machine is introduced systematically in this paper.In order to fill cement mortar and flyash mortar into gob area,the construction technology of high pressure filling instrument,cast-iron grouting tubes and sealing with cement was used.In the information construction period,we adjusted design methods and improved construction technology according to the experiment results,and archived the anticipated aims.We made...
