摘要: 1,147,434. Pipes &c. CONSTRUCTION TECHNIQUES Inc. 1 April, 1966 [7 April, 1965], No. 14703/66. Heading F2P. [Also in Division E1] A cylindrical concrete pipe 190 is reinforced by surrounding the pipe with ring shaped porous bags 192 and supplying cement grout to the interior of the bags to expand them, water leaking from the bags to facilitate setting of the cement to form rings which grip the pipe. The rings have steel reinforcement 193.

摘要: A high pressure bag for pre-stressing a support pack in an underground mine has a fluid impervious liner and three tubular envelopes. The liner is located in the first envelope with end portions of the first envelope and edge strips of the liner folded over underneath the first envelope. The first envelope with the liner therein are in the second envelope, with end portions of the second envelope folded over on top of the second envelope. The second envelope is located within the third envelope which has opposed edges stitched closed. The liner has a nozzle which extends through openings in the envelopes.

摘要: This invention relates to a grout composition comprising a Portland cement, a high alumina cement, anhydrous calcium sulphate, an effective amount of a lithium salt and an effective amount of a strong base. According to another aspect of the invention, instead of using a strong base directly in the grout composition, a first compound and a second compound is added to the grout composition which in use react to form an effective amount of a strong base when the grout composition is mixed with water.

摘要: The invention concerns a method and apparatus for providing yielding support for a hanging wall above a footwall in a mine working. A support assembly is installed between the hanging wall and the footwall, the assembly including a spacer (10), a pack (30) and a grout-inflatable bag (32). Grout is pumped into the bag (32) and is allowed to set to apply a vertical prestess force to the support assembly. The spacer (10) is substantially stiffer in compression than the pack (30), which is designed to yield under the compressive loading applied by the hanging wall. The use of a stiff spacer (10) serves to elevate the yielding pack to a suitble operative height without the allowable slenderness ratio for the pack to be exceeded.

摘要: A yieldable confined core mine roof support including a container and a filler placed within the container. The container is yieldable and the filler is compressible. The combination of a filler within a container produces a mine roof support which is yieldable under a substantially axial load and which increases in load carrying ability as it yields, impeding any decrease in the distance between a mine roof and a mine floor, minimizing or preventing mine roof collapse and mine floor heave, buckling or punching.

摘要: The prop preloading apparatus comprises a frame and means for supporting the frame on an end of an elongate prop in a manner permitting at least limited swivelling movement of the frame relative to the prop about at least one axis transverse to the axis of the prop. The apparatus also includes a flexible preload bag which is inflatable with a settable substance and which is dimensioned to be supported by the frame.

摘要: A support between the floor (22) and the roof (24) of e.g. a mine stope, is made by using an inflatable container comprising an inner bag (10), received in an outer bag (12). An inlet valve (14) extends through both bags as does a relatively higher pressure relief outlet valve (16). In use, air is pumped into the container until it is fully inflated, following by a grout, the air escaping via the valve (16) until the inner bag (10) is filled.
