Application of Pressure Grouting in Foundation Treatment in Old Mined-out Area along Taiyung-Zhongwei-Yinchuan Railway |
| |
| Abstract: | When passing the untreated mined-out area along the LDK629+950～LDK630+650 Section of Taiyuan-Zhongwei-Yinchuan Railway, serious hazard may occur. The scheme for the foundation treatment in such old mined-out area was analyzed to the extent that, combining the site example, the treatment depth, width, hole position arrangement and mixture ratio of grout and other construction techniques thereof were elaborated. The practical result proves that the engineering quality is guaranteed. |
