我们在野外遇到了如何利用洛阳铲打深钻的问题(10米左右),大家首先想到的就是用几根木棍接起来,加深钻进,但在实际工作中发现该方法有以下缺点:(一)不能保证井壁垂直,(二)提升下降一次很困难,(三)因棍太长,弯曲度太大,提升时易折断,甚至要发生人身事故。(四)效率不高。为 We encountered in the wild how to use Luoyang shovel deep drilling (about 10 meters), we first think of is to use a few sticks to pick up and deepen the drilling, but in practice found that the method has the following disadvantages: (a ) Can not guarantee the vertical wall, (b) to ascend and descend once is very difficult, (c) because the stick is too long, the curvature is too big, it is easy to break when lifting, and even the personal accident happens. (D) inefficient. for
