Definitions

  • ABSTRACT A method of reaming through holes by destroying the soil layers adjacent to the hole, and-a device for effecting this method, in which the reamer is provided with means used for destroying in the hole the adjacent layers of the soil.
  • Patentgd May 1, 1973 2 Sheets-Sheet -2 The present invention relates to methods of reaming ground through-holes, and to devices for effecting these methods.
  • the above method is disadvantageous in that the formation of holes of large diameters may bring about bulging which may result in destruction of constructions, such as railway tracks or highways, disposed thereabove.
  • Experiences show that the abovedescribed method can be applied only in the cases when the diameter of the hole does not exceed 400
  • the prior art method of forming reamed holes by packing consumes large quantities of energy
  • the working member (tool) of the device is essentially a reamer, Le, a conically-shaped body.
  • the reamer is drawn through a hole by means of jacks acting on the reamer through the intermediary of rods.
  • the devices that act upon the ground dynamically incorporate essentially a percussive mechanism in which a reamer is mounted in the head portion thereof. Under the action of an impact impulse the devices are moved forwardly and their reamer moves the soil aside, thereby reaming the hole.
  • All the afore-described devices can be used only for carrying out methods of reaming holes by packing the soil.
  • a primary object of the present invention is to provide a method of reaming holes, which is based on the principle of removal of the soil from the hole rather than on the principle of packing the soil adjacent to the hole, and furthermore provides for a device for carrying out the inventive method.
  • the device is essentially a body which is moved through thehole by means of a drive, and includes a reamer mounted at the head por' tion thereof.
  • the walls of the reamer constitutea lattice and form in the tail portion of the reamer a chamber which is connected with a compressor, being provided at the front portion thereof with a nozzle.
  • the lattice walls of the reamer from rings-cutters of different sizes, which are arranged one after another as their diameters increase, and which are interconnected by ribs.
  • ribs interconnecting the rings-cutters are disposed in such a manner so as to protrude outside relative to the rings.
  • the aforementioned obstacles or boulder are moved aside during operation of the device.
  • FIG. 1 shows a ground through-hole reamed for 3.
  • FIG. 2 shows a longitudinal sectional view of a first embodiment of the device for reaming the hole by the method according to the invention
  • FIG. 3 is a section taken along line 111 in FIG. 2;
  • FIG. 4 is a section taken along line lV--lVin FIG. 2;
  • FIG. 5 shows a longitudinal sectional view of a second embodiment of the device for effecting the' method of reaming the hole according to the invention.
  • FIG. 6 is a section taken along line Vl-Vl in FIG. 5.
  • the method according to the present invention is adapted for reaming through-holes which by means of any conventional device.
  • Holes may bereamed with any of the belowfrom the hole by an air flow generated by the compressor and which directed along the hole being reamed.
  • the method can be applied to the reaming of holes in any soil, in a coal seam, or the like.
  • FIG. 2 shows an embodiment of the device designed for carrying out the method according to the invention.
  • the device comprises a percussive mechanism 1 consisting of a body 2 with a percussor (not shown in the drawing) movable within the body; and a reamer 3 secured tothe front portion of the body 2 of the percussive mechanism 1.
  • the reamer 3 is formed by ring-shaped cutters 4 of different diameters, arranged one after another as their diameters increase.
  • the cutters 4 are interconnected by ribs 5 which are secured by means of a coupling 6 (FIG.2 on the body 2.
  • the ribs 5 are made so that they protrude outside relative to the cutting edges of the cutters 4. Because of this construction, in case the reamer encounters a boulder or some other obstacle that cannot be ground or packed, the latter is moved aside by the inclined surfaces of the ribs 5.
  • the reamer 3 At its front or leading end portion the reamer 3 is provided with a nozzle 7, and at its trailing end portion it is connected, by means of a shell 8, with a chamber 9 into which compressed air is supplied from a compressor (not shown in the drawing) through a pipe line 10.
  • a support valve 11 Mounted on the pipe line 10 is a support valve 11 which distributes the supply of the compressed air into the body 2 of the mechanism 1 and inside the chamber 9. The compressed air used by the mechanism 1 is also delivered into the chamber 9.
  • a disc 12 with nozzles 13 which are disposed tangentially and are inclined relative to the nozzle of the reamer 7 (FIGS. 2 and 3).
  • Theface wall 14 of chamber 9 is made of an elastic material, such as rubber.
  • the device functions as follows:
  • the nozzle 7 of the device is brought into the preliminarily formed hole 15 as shown in FIG. 1, and which extends between two end shafts l5 sunk into the ground.
  • the mechanism I starts delivering blows against the reamer 3, thus providing for advancement of the device along the hole.
  • the adjacent layers of the soil are cutoff by the annular cutters.
  • the soil passes through the lattice walls of the reamer, and is then ground and carried away to the outside by the air flow along the preliminary hole '15 through the nozzle 7.
  • FIG. 5 shows another embodiment of the device for I reaming holes through the method according to the present invention.
  • the device comprises a percussive mechanism 17 consisting of a body 18 with a percussor (not shown in the drawing) being movable within the body; and with a reamer 19 being secured on the front portion of the body 18 of the percussive mechanism 17.
  • the reamer 19 is made integral with a chamber 20 and is provided at the front portion thereof with a nozzle 21.
  • the walls of the reamer and nozzle are provided with orifices 22 (FIGS. 5,6) and 23 (FIG. 5), respec tively.
  • ribs 24 By means of ribs 24 the reamer l9 and chamber 20 are secured to a coupling 25 which, in turn, is mounted on the front portion of the body 18 of the percussive mechanism 17.
  • the face wall 26 of chamber 20 is made in a manner analogous to that described with reference to the first embodiment of the device and has an analogous designation.
  • Compressed air is delivered into the mechanism 17 through a hose 27, and into the chamber 20 through a hose 28.
  • the device operates in a manner analogous to that of the device of the first embodiment.
  • the adjacent layers of the soil I are pushed through the orifices 22, and soil particles 29 are conveyed to the outside by the compressed air along the preliminary hole 30.
  • the orifices 23 of the nozzle 21 are designed to prevent packing of the soil disposed ahead of the reamer 19.
  • a device for reaming ground through holes by destroying the soil layers adjacent to the hole simultaneously with the blowing-through of said hole in the direction of its reaming comprising a body; a drive for displacing said body through said hole; a reamer mounted at the leading end portion of said body and having lattice walls; said walls of said reamer forming at the trailing end portion thereof a chamber; a compressor communicating with said 'chamber;and a nozzle being provided at the leading end of said reamer.
  • a device in which a disc accommodating nozzles built therein, mounted tangentially and inclined in the direction of said nozzle of said reamer, is installed inside said chamber of the reame capably of rotating freely.
  • a device in which the face wall of said chamber of said reamer is made from an elastic material and is provided with a out which in the course of the face wall deformation forms an orifice.
  • a device in which the walls of said reamer are formed by a system of rings-cutters of different sizes, arranged one after another as their diameters increase and interconnected by ribs.
  • a device in which 'said ribs interconnecting said rings-cutters protrude outside relative to said rings.
