Definitions

  • a 'known method consists in letting a drill-deflccting member down into the hole.
  • the defiecting member consists of a cylindrical body with an oblique surface at its'one end, so that this end is shaped somewhat like a wedge.
  • the drilldefiecting member is either dropped down into the hole, without being turned in any particular direction, on its longitudinal axis, but with the thin edge uof its wedge-shaped portion directed upwards, oro it is screwed to a bore-rod or pipe and let down at the cnd of the same, whereupon the screw connection is dissolved and the rod removed whilst leaving the deflecting member in the hole. .
  • the drill that is then lowered is dey flected by the top oblique surface of the deflecting member.
  • the present invention relates in general to a method of this kind.
  • the ⁇ fundamental idea of the invention is to fix the hole-correcting or drill defiecting' means in the position where the correcting operation is to be carried out in such a manner as to be absolutely immovable.
  • correcting-means is embedded or fixed in' the hole in different ways according to the nature of the stratum tobe drilled. It 'the stratum is solid the method adopted accordance with the invention is to lodge the wedge-shaped member in a fiuid fixing material that sets and hai-dens more or less gradually, such as cement, this material being preferably carried down into the hole by the wedge-.shaped member itself, and being allowed to run out into the hole at a vcertain moment, preferably at the moment when the Wedge carrying the fixing material ieaches the bottom of the hole.
  • a preferredv procedure consists in causing the fixing ma-v terial to be let out at theproper moment by an automatic appliance.
  • the wedge-shaped member employed in practising the said method- may consist for example of a hollow body composed of two parts,one of which is formed in the known- 'manner so ,as to be partly cylindrical and parti;v wedge-shaped and arranged to contain ⁇ the fixing material.
  • a bolt' adapted to move in the direction of its length may be arranged in the lower cylindrical part of the wedge-shaped member in such manner as to be shifted when the member strikes the bottom of the bore-hole and to deala shar blow against the partition so as to smas it 1and bring about' the above described resu t.
  • the invention contemplates a deiiecting member of a special form. lnthis specially sha ed defiecting member an elongation exten ing from the member in the shape of a bladeisprovided that is caused to sink, or is generally driven, into the bed or bottom" of the bore-hole and which prevents the defleeting member from beingv turned out of its proper position.
  • this blade lanchors the wedge-shaped dfiecting member to the bottom of the bore-hole.
  • the blade may consist of a member in the shape of a fiat sword with a cross-shaped cross-section attachedto the lower end of the cylindrical portion of the drill-defiecting wedge.'
  • a means for accomplishing this 'result forms another feature of this invention iand this comprises vdevices for letting the de fleetingv ⁇ s fido'wn lthe bore-hole in several -sta dditional section (or sections) of' bore-rod'slbeing inserted in the line of boreerodsat each stage.
  • the proper adjustment as to directionl is obtained with theaid of the two adjacent bore-holes or at least one of' them.
  • this means is held up at the end of each stage by a support at the head of the pipe in the borehole.
  • An advantageous form of this support is that of a pair of tongs.
  • the deflecting means is turned into the proper direction and held inits correct position with the aid of a rope that is stretched from one of the adjacent holes to the top of the head-frame over the hole.
  • This rope serves as a ,directing member against which guide arms slide that are fixed tothe bore-rods by which the deflecting means is suspended.
  • the sections of bore-rod inserted at the various stages are held in the first place by the said tong-like support and be- -sides, to prevent swinging of the bore-rod line further up, by a clamp-ing device that is clamped to a bore-rod and fixed to the head-frame.
  • the bore-rods are furthermore brought intov a perfectly vertical line with the-central axis of their bore-hole by caus-l ing the plumb bob of a plummet line to settle over the center of the. adjacent bore-hole.
  • the invention contemplates a connection between bore-,rod .and the deflecting memberby' means of, a special coupling appliance inserted between ther'od and thel said means,
  • the coupling appliance being attached to the deflecting member by a link adapted to auto; matically disconnect the deflect-ing member when it lands upon the bottom of the hole.
  • Fig. 1 illustrates an elevation of an entire contrivance for letting the correcting means or drill deflecting means down into the boreholes
  • Fig. 2 is a plan view of a tong-shaped bore-rod supporting device
  • Fig. 3 is a sectional view 0l the connection between the boreehole and the drill-deiiect'ing member on an enlarged scale
  • Fig. 4 illustrates the manne-r in which the new drill-de'flecting member is dropped down into the hole, how it is severed from the rod by the shearing of thel connecting bolt, and how kthe subsequently lowered drill is deflected.
  • Fig. 5 is a vertical sectional elevation of ua bore-hole with a correcting or drill-deflecting means therein,
