The HTT Model’s design allows the
tunnel to be significantly reduced in
length, up to 60%.
Basically, a 100 m deep HFR tunnel
can be shortened to approximately
60
m.
Static dimensional layout
L = maximum usable length 22,000 mm
HSC = maximum usable height below the tie
beam 6,500 mm
HST = maximum usable height below the beam 6,100 mm
P = depth according to request
S = sliding direction
I =
maximum standard distance between
the pillars 5,000 mm
C = compression percentage does not exceed
40%
of depth
%
= the standard roof slope is 15%
Optional single-pitch roof
version also available
