    • The invention relates to a method for decontaminating soil containing harmful substances, wherein a number of bore holes (11) are advanced to the areas at the edge of the area (21) of contaminated soil by means of a course controlled boring method, then under a continuation of the boring a directed injection of at least one appropriate injection medium (8) from the bore holes (11) is carried out such that the harmful substances are forced into a smaller soil area (21) and are finally removed. Furthermore, the invention relates to a boring head for carrying out the method according to the invention. The boring head includes a tubular boring head body with an inner flow passage and a boring head tip connected to the boring head body and having a convex tip surface the head tip has a plurality of openings connected to the inner passage. The head tip further includes a control surface inclined relative to the longitudinal axis of the head tip towards the surface area of the tip so that an injection medium can be injected through the inner passage and out through the plurality of openings.
    • 本发明涉及一种用于净化含有有害物质的土壤的方法,其中通过课程控制的钻孔方法将多个钻孔(11)推进到污染土壤区域(21)的边缘的区域,然后在 执行钻孔的继续,从钻孔(11)定向注射至少一个适当的注射介质(8),使得有害物质被迫进入较小的土壤区域(21)并最终被去除。 此外,本发明涉及一种用于实施根据本发明的方法的钻头。 该钻头包括具有内部流动通道的管状镗孔本体和连接到钻头主体的镗头头部,并且具有凸出的顶端表面,头部顶端具有连接到内部通道的多个开口。 头尖还包括相对于头尖的纵向轴线朝向尖端的表面区域倾斜的控制表面,使得注射介质可以通过内部通道注入并穿过多个开口。

    • The drilling device is for creating bore-hole branches in unconsolidated rock. The device includes a fully-controllable pilot drill head with drill rods attached thereto. The pilot drill head has an opening on its periphery. The pilot drill head has further outlet openings through which a reinforcing-action drill suspension may be dispensed into a site where a bore-hole branch is to be created. An inner drill head is mounted for longitudinal movement within the pilot drill head and may be deflected out of the pilot drill head and its path by a deflection part within the pilot drill head. Upon its deflection, the inner drill head is directed through the opening on the periphery of the pilot drill head and into a bore-hole branch site.
    • 钻孔装置用于在松散的岩石中产生孔洞分支。 该装置包括具有连接到其上的钻杆的完全可控的导向钻头。 导向钻头在其周边有开口。 导向钻头具有另外的出口,通过该出口可以将增强作用的钻井悬架分配到要产生钻孔分支的位置。 内钻头被安装用于在导向钻头内纵向移动,并且可以由导向钻头中的偏转部分偏转到导向钻头及其路径之外。 在其偏转时,内钻头被引导通过导向钻头的周边上的开口并进入钻孔分支位置。
