Progress On Fort Peck
Dam Nearly Equals That
OF Month Of August

II is difficult to say which par
ticular activity at Ft. Peck deserves
prior mention for progress made
during the first week of September
Whether il is the performance of
the four dredges. with their output
OF | ,347,930 cubic yards, or the tun-
neling, with 455 lineal feet ad-
vance of enlargement excavation,
or progress al the spillway. where
high work on the gate structure
moves across the widest part of
the channel toward river level.
which should be recounted above
other work, cannot be determined.
| Certain it is that at no time since
the start of. operations have such
rapid strides been made at the
Project as are being recorded at
this time.
From the standpoint of interest,
the ini 'ial steps toward placement
of the steel plate lining in No | tun-
nel should be mentioned. First of
all. the system of double tracks.
which served TO bring out muck
trains and to take in concrete
trains during enlargement work,
has to be taken up. Now that en-
lareement work is completed and
tracks are being torn up from the
main shaft TO the outlet portal.
The dirt and debris under the ties is
being taken out and new system
of tracks is being laid down The
old system consisted of double
tracks at 3~foot gauge with the ne.
cessary cross-overs. The new sys-
tenn cnsists of q single track of 3.
foot gauge on the centerline strad-
died by a pair of rails on 6 foot
gauge. The Wide-gause tracks are
for the special wheeled carriages
which will be used TO support the
sections of "a foot 8,inch pipe as
they are rolled into the tunnel
With the tracks laid in this way,
an electric locomotive can push
one section at a time to its proper
place in the tunnel. Arrived in
the bore, the sections will be care
fully Centered. supported on con.
crete blocks and riveted together
at the ends in order to make con-
.inuous pipe from the shaft to the
)utlet portal After the riyeting.
cement grout will be forced through
he holes in the plate, so as to fill
completely the space between the
present lining of the tunnel.
The Chicago Bridge and Iron
Works have completed number
if sections Of the pipe and have
et a number of them over the well
INTO carriages in the pit. At the
ate they are coming through the
hop the contractor should be able
0 lower assembled sections over
he wall as fast as the Government
rews can take them into the tun-
lel and place them. The ease with
yhich t he steel cylinders are
andled end lowered onto the car
ages in the pit is pleasure to see.
The bottom heading crews in
TO- 4 tunnel made 35.foot advances
,ur days consecutiyely last week.
ince they are now working only
five day week, the 1888 feet re-
1rted for the period shows good
ork. In fact, during the period
ug. nth to Sept. 3rd, inclusive
I8 working days) these same
ews averaged 33 feet 10 inches
II day. All three holes still being
llarged reported total of ASS
heal feet for the five day Of last
eek. Total concrete invert poured
ring seven days was 428 lineal
ct and the same footage of side
Ill and arch was poured.
