    VTS Props

    The Salzgitter Hydraulic Props, now produced

    by VTS and marketed in North America by DSI

    Underground Systems Inc., offer safety on the

    face. They can be easily maintained and operated,

    and, according to the requirements and depending

    on the prop type, readily extended with slip-on

    extension pieces.

    The VTS Props are set by hydraulic pressure

    pump and fed into the setting gun via a setting line

    installed in the face. The setting gun will be put on

    the filling valve of the prop, mechanically securedwith a one-hand locking mechanism, and operated

    by one hand.

    The pressure flows through the setting gun and

    filling valve into the interior of the prop and causes

    the internal prop and the piston to telescope. After

    having been set against the support (articulatedbar) the prop is braced with the setting force

    existing in the setting line, thus immediately

    supporting the roof.

    Due to the rock pressure the prop can now be

    loaded till the set pressure on the operating valve

    will have been reached. If the nominal pressure is

    reached, the operating valve will open and some

    hydraulic fluid will be sprayed off till a pressure

    spring will close the operating valve again.

    This process repeats itself every time the nominal

    pressure is reached. Thus, the prop remains

    always protected from overload by the rockpressure.

    Large lifting heights permit a large range of

    convergences.

    Due to the possible extensions according to the

    prop types, the prop length can be readily adapted

    underground to the changes of the face heights.

    The prop can be withdrawn with a releasing key

    that extended by means of a rope or a chain

    actuates the releasing valve from a safe place

    of the miner and lets the hydraulic fluid escape

    from the cylinder. An installed return spring rapidly

    retracts the internal prop. Herewith, the prop is

    ready for use again for a new setting operation.

    Crib Systems

    Tri-Log Wood Crib

    Introducing the Tri-Log System, the new cribbing

    method from DSI Underground Systems Inc.

    that saves you time and money. It is designedto replace four and nine point cribs as well as

    other four-sided structural wood systems. This

    system uses only three pieces to build each

    course compared to four or more pieces for the

    competitive systems. Thats 25% fewer pieces, so

    youll benefit from significant reductions in labor,

    handling and transportation costs.

    The unique interlocking design delivers 100%

    contact between the nested timber layers. This

    efficiency means Tri-Log cribs give up to 50%

    more support than the average four point crib.

    The tripod configuration and interlocking design

    provide superior stability, allowing higher aspect

    ratios than conventional cribbing.

    The angle-cuts of the notches reduces stress

    at the overlap and maximizes carrying capacity

    throughout the load cycle.

    Tri-Log cribs are slid into place tight to the roof

    rather than having to be lifted over the previous

    course and can also be used with ACI prestressing

    grout bags or headers.

    The finished wedge-shaped cribs promote moreefficient ventilation and air flow than solid square

    or rectangular cribs.

    Tri-Logs are available in standard lengths up to

    60 in either 4" or 6" sizes to handle capacities in

    excess of 800 tons. Custom designs for virtually

    any capacity can be produced.

    Steel 4-Flange Liner Plates

    DSI Underground Systems Inc. selection of under-

    ground supports, the widest in the world, affords

    the contractor, the designer, and the owner a

    matchless combination of high performance andtunneling at low cost.

    One of these products alone - liner plates - offers

    these outstanding advantages:

    Economy of construction in time, excavation,

    material, manpower.

    Maximum support per given length with

    minimum weight of steel.

    Standard variation of plate design for all shapes

    of tunnels in dry or wet ground.

    Predictable strength, fire resistant.

    Continuous support during the critical mining

    phase in soft ground tunneling. Easy to store, handle and erect, whether the

    tunnel is straight, curved, circular, elliptical or

    horseshoe in shape.

    Gasket plates that seal joints, stop water

    leakage and reduce air loss when water is a

    problem.

    Steel liner plates provide a relatively light-weight,

    easy-to-handle, safe support for soft ground

    tunneling because the ground that supplies the

    loading also supplies the resistance to the load.

    The liner plate assembly simply distributes andtransmits the load to the surrounding earth. As a

    steel liner plate ring takes load vertically, it tends

    to deflect inward at the top and outward at the

    sides. The ground resists deflection of the lining by

    developing a passive force equal in magnitude and

    opposite in direction to the force exerted by that

    of the lining. The diagram on the left illustrates this

    principle.

    The ability of the surrounding ground to resist the

    outward bulge of the liner plate ring is the key

    to vertical load support. With the ring confined

    to a small amount of deflection, the thrust lineinduced by the load is forced to follow the ring

    of liner plates. Thus, the ability of the assembly

    to withstand the applied load depends upon its

    ability to transmit ring thrust from plate to plate

    around the ring. Obviously, this ability is enhanced

    by the four-flange design of DSI Underground

    Systems Inc. plates.

    There are various methods for determining the

    required strength of tunnel linings. Nevertheles, the

    type of ground, the location and depth of cover,

    the size and length of the tunnel, level of groundwater, superimposed loading, and history always

    guide these calculations.

    DSI Underground Systems Inc. liner plates can be

    purchased in 16" and 24" widths as corrugatedor smooth plates. Liner plates are formed from

    one piece of metal to provide longitudinal and

    circumferential flanges. The plates can be

    galvanized and/or bituminously coated and grout

    holes with plugs can be included. For special

    conditions gasketed liner plates and tapered liner

    plates can also be manufactured. Liner plates can

    be installed alone or in conjunction with steel ribs

    if additional support is required.

    General Specifications

    The following paragraphs are offered as a guide

    for those who write and issue specifications forsteel liner plates as underground supports.

    Scope

    These specifications are intended to cover the

    fabrication and installation of liner plates in

    tunnels constructed by conventional methods.

    Tunnels excavated by full face, heading and

    bench, or multiple drift procedures are considered

    conventional methods. Liner plates used with any

    construction method utilizing a full or partial shield,

    a tunneling machine, or other equipment which will

    exert a force upon the liner plates to propel, steer,

    or stabilize the equipment are considered specialcases and are not covered by these specifications.

    Description

    Cold-formed steel liner plates conforming to the

    specifications below shall be furnished to the sizes

    and dimensions required on the plans. Such plates

    shall be installed at the locations designated on

    the plans or as designed by the engineer or the

    responsible authority.

    Design and shape of the liner plates shall be

    such that erection and assembly of the liner plate

    structure can be completely and readily erected

    from inside the tunnel.

    Plates shall be accurately curved to suit the tunnel

    cross section, and all dimensions are of such size

    and accuracy that plates of similar curvature will

    be interchangeable.

    Bolts on both the longitudinal and circumferential

    joints shall connect all plates.

    Grout holes 2" in diameter shall be provided, as

    shown on the plans, to permit grouting as the

    erection of tunnel liner plates proceeds.

    Material Specifications

    Thickness tolerances shall conform to AASHTO

    specification for Highway Bridges, Section 16,or comparable AREMA Manual for Railway

    Engineering, Chapter 1, Section 4~15.

    The Tunnel Liner Plates shall be fabricated from

    structural quality, hot rolled, carbon steel sheets

    or plates conforming to the specification of ASTM

    designation A1011.

    The mechanical properties of the flat plate and

    sheets before cold forming shall be:

    Tensile Strength psi 42,000 Min.

    Yield Strength psi 28,000 Min.

    Elongation in 2", % 30 Min.Forming and Punching of Liner Plates

    All plates shall be formed from one piece of

    metal to provide longitudinal and circumferential

    flanges. They shall be punched for bolting on

    both longitudinal and circumferential flanges in

    accordance with the manufacturer's standard

    spacing, and shall be a multiple of the plate length

    so that plates having the same curvature shall be

    interchangeable and will permit staggering of the

    joints.

    Grout holes with plugs shall be provided atspacing sufficient to allow filling of all voids with

    grouting material.

    supports, and the permanent support is monolithic

    concrete or reinforced concrete pipe, and theopening between the back of the pipe and the

    inside of the liner plate is filled with grout or sand,

    liner plates are furnished black, not coated.

    When so specified, the liner plates will be

    galvanized to meet the current ASTM Specification

    A 123. In addition, the liner plates when so

    specified, shall be bituminous coated to meet the

    current AASHTO Specification M190.

    Bolts and Nuts

    Bolts and nuts used with four-flange liner plates

    shall be not less than " diameter for 7 gageplates and lighter, and not less than 5/8" diameter

    for liner plates heavier than 7 gage. They shall

    be quickacting coarse thread with material

    conforming to ASTM Specification A307.

    When required, the bolts and nuts shall be hot

    dip galvanized to conform to ASTM Specification

    A 153.

    Installation

    Liner plates shall be assembled in accordance

    with the manufacturer's instructions.

    Voids occurring between the liner plates and the

    surrounding ground shall be pressure grouted as

    directed by the engineer in charge to completely

    fill all voids. The grout shall be forced through the

    grouting holes provided in the liner plates.

    Typical Liner Plate Installations

    Liner Plates OnlyThe most obvious advantages of

    this structure are that maximum

    support per foot of tunnel is

    obtained with minimum weight

    of steel. Liner plates, properly

    grouted or backfilled as tunneling

    progresses, form a dependable

    structure in either cohesive or

    non-cohesive ground. Liner plate

    structures generally require no

    additional support in tunnels up to

    14' in diameter.

    Ribs Inside Liner Plates

    To give extra support to a liner

    plate structure in large diameter

    or heavy load conditions, ribs can

    be added inside the ring. Liner

    plates then act as lagging and are

    normally lighter in gage.

    This additional support usually

    requires an increase in thediameter of the driven bore to

    maintain the dimensions of the

    finished inside diameter. This

    method is often used in shaft

    construction.

    Liner Plates Between Ribs

    This type of structure is less

    common than ribs inside liner

    plates because it is harder to erect.

    It does offer a practical trade-offunder certain tunneling conditions.

    Three basic ways sof installing plates in tunnels or shafts are illustrated here; each has its

    advantage in a particular application or ground condition.
