  • the drilling machine together with the connector and drill string are placed in a cladding tube which, when provided with a set of sleeve ears, forms a guide tube which is close to the inside from its inside End of the degradation direction a collar permanently formed, which forms a kind of driver and which is in a striking contact with side shoulder of the connector during operation of the device, which achieved in succession by the drill bit recovery progress, a feed of the cladding tube in the direction the recovery is due to the impact between the side of the connector and the rear of the collar, further on the connector exerts a pressure the drill pipe, which is acted upon by the strokes and rotations of the drill.
  • the connector also exerts a function of the feed element of the cladding tube in addition to energy supply of the drill bit and their leadership in the borehole.
  • a drill bit 1 is formed as a unitary element and mounted on a mandrel 2.1 of the connector 2 .
  • the connector 2 is connected from the opposite side to the extraction direction with a boring bar 4 fixed from the other side in a drill (not shown in the drawing) placed on a carriage (not shown in the drawing).
  • the drill bit 1 is introduced together with the connector 2 and the drill string 4 in a cladding tube 3 .
  • the cladding tube 3 is provided in an inner collar 3.2 , which is advantageously attached to its inner wall 3.1 by welding process, also to reinforce the connection of the cladding tube with its collar 3.2 on the circumference of the cladding tube 3 is a series of openings 3.3 formed after insertion of the Federation 3.2 are welded into the hole of this cladding tube 3 .
  • the collar 3.2 is inserted so deep inside the cladding tube 3 , that its rear surface 3.4 is arranged obliquely to the main axis, is used for contact with side 2.2 of the connector 2, which this connector 2 is inserted in a central opening 3.6 of the Federal 3.2 , the side paragraph 2.2 of the connector 2 is located between the transition of the thickened part of its dom 2.1 and 2.3 connector, and is also formed obliquely to the main axis of the device, wherein the slope of the rear surface 3.4 of the Federal 3.2 and 2.2 page side are identical.
  • the connector 2 is provided in a formed in its axis through-hole 2.4 , which is wider and drawn by the connection with drill pipe 4 , and further to the output and shock with a narrowed part of the central channel 1.4 1.3 in the Drill bit 1, the through hole 2.4 is narrowed and is used exclusively for swimming through the water emulsion or the compressed air.
  • the narrowed part 1.4 of the center channel 1.3 is formed in the drill bit head 1.1 of the drill bit 1 and has a connection with the drill bit 1 formed in this oblique holes 1.5, directed forward, their outputs to the part of the flat face 1.7, as well as at the oblique Front 1.6 of the drill bit head 1.1 of the drill bit 1 have.
  • the drill bit 1 is also provided in an inclined from the narrowed center channel 1.4 backward additional opening 1.8 , and which has an output in one of lateral recesses 1.9 of the drill bit 1 .
  • the front side of the drill bit 1 immediately her flat part 1.7 and her oblique face 1.6 are equipped with curved elements that have depending on mined material or inserts of carbide 1.10 or appropriately shaped dome 1.11 as a sprue of secret material such as the drill bit 1 .
  • the drill bit 1 has in its center channel 1.3 from the opposite end face 1.12 on inner walls of boards 1.13 , after placing on the mandrel 2.1 of the connector 2, the drill bit 1 and its rotation, in this case, left (looking from the end face 1.7 of the drill bit 1) to insure against unwanted solution with connector 2 , because the projections on the connector shaft 2.3 of the connector 2 to take the space in created by the boards 1.13 and inner walls of the center channel 1.3 niches.
  • the center channel 1.3 of the drill bit 1 is round and is provided with a corresponding thread 1.14 , which cuts with corresponding threads 2.7, cut on the lateral roll surface 2.5 of the connector 2.
  • the drill bit 1 and connector 2 together with it form a threaded connection.
  • the oblique openings 1.5 in the drill bit head 1.1 and center channel 1.3, 1.4 are also used to supply the shock of the drill bit 1 with degraded rock water emulsion, so not only to facilitate the removal of the drill dust, and to avoid the resulting dust content.
  • the water emulsion is fed from the drilling machine through drill pipe 4 to the through hole 2.4 of the connector 2 and from there to the center channel 1.3 , further through the narrowed center channel 1.4 and injected above mentioned oblique openings 1.5 of the drill bit head 1.1 .
  • the drilling dust flows from the excavation site through lateral recesses 1.9 of the drill head 1.1 of the drill bit 1, further through recesses 3.5 in the collar 3.2 of the cladding tube 3 .
  • the device acts in this way that the percussion drill or percussion drill the beats and rotations of the scheduled in its holder drill pipe 4, the following the strokes and rotations of the fastened on its end connector 2, further the shocks and turns, at his Dorn 2.1 stored drill bit 1 transmits, and this provided with their front side 1.7, 1.6 in inserts of carbide pins 1.10 and / or dome 1.11 hitting broken rock, crushing it.
  • the crushed elements flow under the influence of the water emulsion in the direction of the outlet of the well, and drill pipe 4 under the influence of the constant pressure exerted by carriage to the drill pushes the drill bit 1 in front, while moving forward the sheath 3 , due to the transmitted impacts of the side paragraph 2.2 of the connector 2 of the rear 3.4 of the Confederation 3.2.
  • the entire drill pipe 4 and the entire casing 3 of the most 3 meters in length are introduced into the borehole practically 15 centimeters average, stops the extraction, disconnects from the holder of the drill from the drill pipe 4 , then the drill moves back to the gun carriage and the drill pipe 4 rotates a new, second, or next drill pipe forming the extension of the first drill pipe 4 and attaching this second or next to the drill.
  • the second cladding tube and possibly the next Cladding tubes are already without inner collar 3.2, since it is already superfluous. In this way, the holes in horizontal position, which extend to 15 meters, resulting in the ducts and drill rods of 3 meters in length, allows a drilling kit of five sections to put together. After completion of the hole and
  • Conversion of the rotations of drilling machine disconnects the drill bit 1 from the connector 2 and this remains in the borehole, however, drill pipe 4 or set of drill pipes extend from the casing 3 or from the set of conduits remaining in the drilled hole.
  • drill pipe 4 or set of drill pipes extend from the casing 3 or from the set of conduits remaining in the drilled hole.
  • In the ducts brings under pressure hardening substance, which emerges through the holes formed in cladding holes 3.9 , filling the space around these pipes around and solidifies with secret soil, reinforcing it. So execution of the next hole requires preparation of the new drill bit and a sequential set of sheaths, by continuing to use the remaining elements if they did not wear out.
