| 121 | Method of pressurizing and stabilizing rock by periodic and repeated injections of a settable fluid of finite gel strength | US175047 | 1980-08-04 | US4370077A | 1983-01-25 | Stirling A. Colgate |
| A finite region of overpressure can be created in solid underground formations by the periodic injection of a fluid that has finite gel strength that subsequently, after each injection, partially sets--i.e., equivalently becomes a very much stronger gel. A region of overpressure is a region in which the static, locked in pressure is larger than what was there before. A region of overpressure can be used to prevent a roof of a tunnel from caving by adding compressive stresses in the roof. A sequence of regions of overpressure can be used to lift an arch or dome underground, squeeze off water or gas flows, stabilize dams, foundations, large underground rooms, etc. In general, the stress or pressure distribution in rock can be altered and engineered in a fashion that is more advantageous than what would have been the case without overstressing. | ||||||
| 122 | Injector | US044734 | 1979-06-01 | US4260295A | 1981-04-07 | Elof Vestlund |
| An injector which is intended for the injection of material under high pressure through bores or other holes in rock or other solid material is provided with an injector pipe, a tubular shell, and injector nozzle and an expansion device which, during the injection operation, seals against the wall of the bore. The injector nozzle is releasable from the end of the injector pipe and is disposed to cooperate with a sleeve included in the expansion device in order to press the sleeve against the wall of the bore and in order, together with the sleeve, to form an expanded unit which, after the injection phase, is released from the injector pipe and remains, in the expanded state, in the bore. The injector nozzle is designed as a non-return valve, in that it has a cupola-like valve portion consisting of elastomer material and bridging the end of the injector pipe. The valve portion has through-flow slits which extend obliquely inwardly from the outside of the cupola-like valve portion in a direction towards the injector pipe, such that material pressure against the outside of the cupola-like valve portion realizes a sealing compression of the through-flow slits. | ||||||
| 123 | Method of reinforcing tunnels before excavation | US555242 | 1975-03-04 | US3968655A | 1976-07-13 | William K. McGlothlin |
| This invention relates to a method of reinforcing tunnels which comprises driving a crown drift along the top of the proposed tunnel, driving a pair of wall plate drifts along opposite sides of the proposed tunnel in spaced substantially parallel relation beneath and to one side of the crown drift, drilling a longitudinally spaced aligned or staggered series of small diameter bores downwardly and outwardly in both directions from within the crown drift along the ceiling of the proposed tunnel, drilling other series of similar bores upwardly from within the wall plate drifts along the walls of the proposed tunnel, said ceiling and wall bordering bore patterns being inclined toward one another and of a length such as to produce a skewed overlapped relation, inserting reinforcing rods into the bores of each series thereof so as to produce a metal curtain between drifts bordering the perimeter of the proposed tunnel, grouting the rods permanently in place within their respective bores, filling the drifts back up with concrete and removing the material within the arch defined by the refilled drifts and metal curtain therebetween. The invention also encompasses a method wherein the additional steel curtains are erected to reinforce the tunnel walls that extend downwardly from the floor of the wall plate drifts to a position outside the foot drifts driven along the base thereof. | ||||||

| 136 | Tunnel lining method and apparatus suitable for the purpose | US958511 | 1992-10-08 | US5290125A | 1994-03-01 | Davide Trevisani |
| In a tunnel lining method an apparatus, comprising at least one excavation tool of the chain, belt or band type or the like, is positioned to coincide with the longitudinal axis of the tunnel at a point on its extrados; the tool is made to advance to a predetermined depth in a direction diverging from the tunnel axis so as to create a substantially rectangular cavity from which the tool is withdrawn; said cavity is then filled with concrete to form a cast segment; the aforesaid stages are repeated until a frusto-conical section formed from adjacent cast segments is completed, after which the material within the formed section is excavated to a depth less than the axial length of the section, and the apparatus is advanced through a distance substantially equal to the axial length of the cast segments, the stages being repeated to form each successive section in order to form a lining in which the wider final portion of one section is superposed on the narrower initial portion of the next section; during the execution of one section of cast segments a second tool associated with said first tool executes consolidation/tamping injections with concrete or the like into the region which is to constitute said next section. | ||||||
| 137 | Drill hole filling method and apparatus | US594961 | 1990-10-10 | US5129470A | 1992-07-14 | Onni Issakainen |
| The present invention relates to a method for use in connection with a drilling apparatus for drilling a hole and also filling the drilled hole with a filler. A hole is drilled by using a tubular drill rod with a crushing tool provided at the end of the drill rod, with the crushing tool substantially defining the diameter of the hole to be drilled. A first flushing medium is supplied in the course of drilling, through the hole in the tubular drill rod to at least one opening in the crushing tool and into an annular space defined between the walls of the drilled hole and the outer surface of the drill rod, for carrying crushed material out of the drilled hole. After completion of the drilling operation and removal of the crushed material, a filler is delivered into the hole in the tubular drill rod, into the drilled hole and/or into the ground or bedrock surrounding the hole. A second flushing medium is supplied during the final stage of delivery of the filler such as to remove the remaining filler from the drilling apparatus and the crushing tool prior to any subsequent drilling operation. | ||||||
| 138 | Method for reducing compressed air losses when driving underground cavities supported by compressed air | US602185 | 1984-04-19 | US4623198A | 1986-11-18 | Manfred Nussbaumer; Theo van Lith |
| A method for reducing compressed air losses when driving underground cavities which are supported by compressed air. The part of the inner cavity face exposed by mining is sealed by a viscous medium after breaking away the earth. With a supply of propellant, the viscous medium is applied, in the form of a spray mist which is directed toward the exposed part of the inner cavity face, in such a way that the mist penetrates the substratum without substantially destroying the exposed face. Particles of rock are thus prevented from being detached from the face which is to be sealed. | ||||||
| 139 | Ground freezing method | US303754 | 1972-11-06 | US3943722A | 1976-03-16 | John William Ross |
| An apparatus and method of freezing a large volume of ground for tunnel construction and the like utilizing liquified nitrogen is described. The apparatus consists generally of a series of freeze pipes embedded in the ground, each of the freeze pipes consisting of a conductor tube and an inner header tube. The header tube of each of the succeeding freeze pipes in the series have discharge holes of a predetermined cross-section so that greater control of gaseous and liquified nitrogen pressure can be maintained throughout the system. By means of this method and apparatus more accurate control of ground freezing can be made by merely controlling the inlet liquified nitrogen pressure and the exhaust gaseous nitrogen temperature. | ||||||
