关于定向钻穿越卵石层方法的探讨摘 要:随着定向钻穿越施工的普及和对定向钻穿越施工综合社会效益要求的不断提高,在施工过程中遇到含卵石的地质情况越来越多,针对含有卵石的定向钻穿越施工,掌握科学合理的施工方法就显得尤为重要
本文在总结大量的施工经验的基础上,结合实际,开展了新的工艺讨论和应用,尝试新的注浆、固孔及卵石处理措施,避开塌孔、冒浆现象的发生,同时在管线回拖过程中能够有效保证施工质量及安全,并在实际的施工中取得了良好的经济效益
With the development and raised social benefits of directional drilling crossing construction, and more and more pebbly bed situation in the construction, it is particularly important to master the scientific and reasonable construction method
In this paper, on the basis of summarizing a large number of construction experiences, combined with the actual constructions, carried out the research and application of new processes, tried a new hole grouting, soliding and pebble processing measures, avoided the happening of hole collapse and plasma
At the same time it can effective
