摘要
在地质工程领域,巨厚松散破碎带一直是完钻后固管工作的难题。由于其特殊的地质状况,地层松散且破碎程度高,常规固管工艺难以达到理想效果,本文提出一种极具创新性的固管工艺,即采用阶段性注浆的方式。该方法能有效缩小水泥扩散半径,避免其过度扩散而影响固管质量。通过在实际工程中的应用发现,这一工艺显著提高了固管的稳定性与可靠性,为后续类似复杂地质条件下的工程施工提供了参考借鉴。
In the field of geological engineering,the super-thick loose fracture zone was always a difficult problem in the work of pipe fixing after drilling.Due to its special geological conditions,the formation is loose and broken,and the conventional pipe-fixing process is difficult to achieve the desired results.This paper proposed a highly innovative pipe-fixing process,that was,the use of phased grouting.This method could effectively reduce the diffusion radius of cement and avoid its excessive diffusion to affect the pipe-fixing quality.Through the application in practical engineering,it was found that this process significantly improved the stability and reliability of the fixed pipe,and provides a valuable reference for the subsequent engineering construction under similar complex geological conditions.
