大型机械推运散土堵漏是在塞堵、盖堵等辅助措施不能奏效的情况下将散土高强度地推至漏洞进口处 ,闭气后再修筑前戗来完成抢堵漏洞的整个过程。通过对漏洞发展机理及采用散土堵漏存在的问题的分析 ,提出了相应的解决方法和应注意的事项。分析认为 ,在一定条件下采用大型机械推运散土堵漏方法将会取得其他堵漏方法难以达到的效果。 Large-scale mechanical distribution of earth-based plugging in plugging, plugging and other ancillary measures can not be effective in the case of loose soil high strength pushed to the entrance to the loopholes, and then build a front breath to complete the whole process of looting loopholes. Through the analysis of the development mechanism of loopholes and the problems existing in the application of sand plugging, the corresponding solutions and matters needing attention are put forward. Analysis, under certain conditions, the use of large-scale mechanical loosening plug earth leakage method will be achieved by other plugging method is difficult to achieve results.
