1) directed inclined hole
定向斜孔
1.
In ground pregrouting for water-sealing of western area circulating air shaft, grouting technologies such as drilling directed inclined holes along the tangent line around the shaft, increasing the density of holes and raising the probability of taking off high -angle cracks were adopted.
针对高角度裂隙发育的石英砂岩这类特殊含水层,吸取刘庄煤矿东区几个井筒注浆施工的经验教训,在西区回风井井筒地面预注浆堵水工程中,研究采用了环绕井筒沿切线方向打定向斜孔、增加钻孔密度、提高钻孔揭露高角度裂隙的几率等注浆技术,取得了良好的效果。
2) deviated directional drilling
定向斜井
3) directional angle building
定向造斜
4) deviating and directing
造斜定向
5) directional incline
定向倾斜
补充资料：斜楔式侧孔冲模
工件套在件6上用件9上的台阶定位，而件9用件18防转并且起到圆周方向定位的作用，当上模下行时，件5先将工件压牢，上模继续下行时，由斜楔4推动件11和装在件11上的件8完成冲孔工作。当上模上升时件11在件4的作用下退回，按下件16，工件由与件16相连的件9顶出．
