在高承压水黄土层中掘进井筒，使用冷冻法似乎已成了工程定例，但其高昂的施工费用常令建设者望而却步，而运用廉价的普通注浆的方法进行堵水并能保证井筒安然通过，国内外鲜有成功的先例。作者在河北矾山磷矿西风井施工过程中，依靠科学的分析、正确的判断和打破常规的施工工艺，最终用普通注浆的方法安全顺利地通过了压力高（０８５ＭＰａ）、水量大（１０４ｍ３／ｈ）的第四系含水粘土层，创造了类似地质层中井筒施工的成功范例。通过实验研究，掌握了西风井粘土的主要特性。通过对圆孔扩张问题的讨论，充分论述了劈裂注浆产生的机理、条件和可能性。详细描述了西风井注浆堵水的设计及其原则，首次提出了“反向注浆”的新的概念。工程实践证明它是十分必要和有效的 It seems that the use of freezing method to tunnel boreholes in high-pressure watery loess layer has become an engineering practice, but its high construction cost is often prohibitive for builders, and the use of cheap common grouting method to block water and ensure wellbore safety Adopted by few successful precedents at home and abroad. In the course of the construction of Wanshan Phosphate Rock in Hebei, the author relies on scientific analysis to correctly judge and break the conventional construction technology. Finally, the method of normal grouting passes the high pressure (085MPa) and the large amount of water (104m3 / h) of Quaternary aquifer clay, creating a successful example of wellbore construction in a similar geological formation. Through experimental research, master the main characteristics of westerly well clay. Through the discussion of the problem of circular hole expansion, the mechanism, conditions and possibilities of splitting grouting are fully expounded. Described in detail the design and principle of blockage of water in the west shaft, and put forward the new concept of “reverse grouting” for the first time. Engineering practice proves that it is very necessary and effective
