  • Patent number: 8776479
    Abstract: An anchoring device including an anchoring element suitable for being anchored an object of construction material with the aid of mechanical vibrations. The anchoring element includes a thermoplastic material and a tool. The thermoplastic material forms at least a part of a radially outer surface of the anchoring element, and the tool has a proximal portion and a broadening portion distally of the proximal portion. The broadening portion has an outer second cross-section, the second cross section being larger than the first cross section but being adapted to the first cross section so that the tool can be moved with respect to the anchoring element while the broadening portion is in the axially-extending opening and locally expands the anchoring element while thermoplastic material of the anchoring element that surrounds the broadening portion is in a solid state.

  • Patent number: 8753041
    Abstract: The invention provides an injection, sealing, valving and passageway system for use with hollow rock bolts and hollow injection bars used in mining, civil engineering, tunneling and construction including use with hollow self drilling rock bolts. The invention comprises a plurality of passageways with one or more one way flow valves along the passageways. The invention enables one or more fluids to be pumped into a hollow rock bolt or other hollow elongate member either sequentially or simultaneously without cross contamination of fluids in another passageway or back flow of fluids along the wrong passageway. The invention is typically used to install self drilling rock bolts whereby a drilling fluid is initially pumped through the hollow bolt during the drilling cycle, and then a two part chemical resin or cement grout is pumped through the hollow bolt to anchor the bolt in the borehole.

    Abstract: Disclosed is a method of reinforcing a structure (10) having an elongate hole (14) or drilling the hole having an open proximal end (11) and a closed distal end (16). The method comprises the steps of inserting into the open end of the hole an elongate reinforcement core (20) carrying over at least part of its length an expandable sock (30), introducing a settable liquid (40), such as grout, into the sock at a first pressure so as to cause expansion of the sock toward the wall (18) of the hole (14), the sock being formed from a material which is permeable to the grout so as to allow the liquid to seep through the sock, reducing the pressure in the hole by means of a vacuum tube (23), whilst said introducing step is taking place, to at least a second pressure lower than the first pressure so as to encourage the grout to seep through the sock, to substantially fill the hole.
