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The prop can be withdrawn with a releasing key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.

Steel 4-Flange Liner Plates continued
Galvanizing and Coating
Where liner plates are used as temporary
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.
