Abstract
A liner plate system for lining shafts or tunnels is provided. The system includes a plurality of curved liner plate units and a plurality of line lock plates. Each curved liner plate unit includes a radially outer side and a radially inner side, the radially inner side including a peripherally extending seal recess having a seal material thereon. Each liner lock plate has an inner side and an outer side, the outer side including a seal recess formed therein, the seal recess having a seal material thereon. The curved liner plate units and the liner lock plates arranged to form a curved wall structure.
Claims21
A method of rehabilitating a vertical mine shaft bounded by a concrete wall structure, the method comprising:
- removing an interior portion of the concrete wall structure;
- installing a liner plate system adjacent the concrete wall structure including:
- utilizing a plurality of arcuate liner plate units, each arcuate liner plate unit including a radially outer side and a radially inner side, the radially inner side including a peripherally extending seal recess having a seal material thereon, the seal material having an uncompressed radial thickness greater than a radial depth of the seal recess so as to protrude beyond a primary inner surface of the radially inner side;
- utilizing a plurality of liner lock plates, each lock plate having an inner side and an outer side, the outer side including a seal recess formed therein, the seal recess having a seal material thereon, the seal material having an uncompressed thickness greater than a depth of the seal recess so as to protrude beyond a primary outer surface of the outer side;
- arranging the arcuate liner plate units and the liner lock plates to form a cylindrical wall structure, with a first set of arcuate liner plate units forming a first ring and a second set of arcuate liner plate units forming a second ring, the first ring having a top edge, bottom edge and multiple vertical edge joints, the second ring having a top edge, bottom edge and multiple vertical edge joints, the top edge of the first ring abutting a bottom edge of the second ring to form a lateral edge joint, the vertical edge joints of the first ring circumferentially offset from the vertical edge joints of the second ring, the liner lock plates positioned along an inner side of the cylindrical wall structure with the seal material of the liner lock plates in contact with the seal material of the arcuate liner plate units;
- and
- utilizing threaded members to hold the liner lock plates adjacent the arcuate liner plate units, such that the cylindrical wall structure formed by the combination of the liner lock plates and the arcuate liner plate units is a rigid, unitary structure.
A liner plate system for lining shafts or tunnels, the system comprising:
- a plurality of curved liner plate units, each curved liner plate unit including a radially outer side and a radially inner side, the radially inner side including a peripherally extending seal recess having a seal material thereon;
- a plurality of liner lock plates, each liner lock plate having an inner side and an outer side, the outer side including a seal recess formed therein, the seal recess having a seal material thereon;
- the curved liner plate units and the liner lock plates arranged to form a curved wall structure, wherein with the curved liner plates forming multiple rings, each ring having a first end edge, a second end edge and multiple interior edge joints, the rings arranged end to end such that abutting end edges form multiple end edge joints, wherein the interior edge joints of each ring are circumferentially offset from the interior edge joints of each adjacent ring, wherein the liner lock plates are secured along an inner side of the curved wall structure with the seal material of the liner lock plates pressed into contact with the seal material of the curved liner plate units in order to seal both the end edge joints between adjacent rings and the interior edge joints of each ring.
