• Anchor forces
9. DISPLACEMENT MEASUREMENTS WITH
AUTOMATIC INCLINOMETERS
• The measuring device is installed in the ground where it
measures the movements at different depths
• The most common applications include the monitoring of
railway and road structures, mines and concentration
plants, various banks and foundations, landfills, dams
and other structures
• Temperature profile measurement
• Diverse reporting services of the web service
• Alarm limits
• Entirely automatic
10. AUTOMATIC MEASURING
OF SETTLEMENTS
• Can be installed under ground or
directly to the structure
• The sensors detect even
settlements of 2 – 3 mm
• Reports and alarms via easy web
service
11. ANCHOR FORCE MEASUREMENT
• Load forces of the anchors
• Sheet pile walls, rock anchors etc.
• Optimizing the size and number of the anchors
• Ensuring the working safety
• Outer load factors, ground frost
• Typical measuring range 0 – 1500 kN
12. PORE PRESSURE MEASUREMENT
• Used in securing piling sites and terraces
• Also used to support foundation planning
• Monitoring earth-fill dams
• Measuring range 0 – 5 bars
13. TEMPERATURE PROFILE MEASUREMENT
• Exact digital sensors
• For monitoring the melting and
freezing of the ground
• Dam leakages
• Warming need for concrete
casting
• Structures behaviour as
temperature changes
14. WATER LEVEL MEASUREMENT
• Can be used for monitoring the water level of
groundwater, water systems and reservoirs
• More secure and economical than conventional
monitoring methods
• Measuring range 0-5 bars
• Several pressure sensors can be connected to a
central processing unit
15. EXTENSOMETER MEASUREMENTS OF
ROCK
• Rock movements are measured, for example,
during the excavation work of tunnels, parking
halls and other underground spaces
• The reliability of modelling can be verified by
automatic measurements
• Measuring devices that can be read remotely can
also be installed in fairly inaccessible locations
• Measuring range is 25–100 mm
17. Baseline
•The 2,3 km highway tunnel
is in many locations located
directly below buildings
•Need for exact information
of the rock tension and risk
minimizing
Our solution
•Automatic extensometers
which monitor rock
movements
•The measurements started in
2014 and continue still
Result
•Exact and real time
information of rock
movements
•The information helps to
estimate the impact of
each blast
•Automatic alarms warn
about potential changes
Case Rantatunneli:
FinMeas automatic extensometers are the tool
of choice for the Rantatunneli Alliance project
in Tampere
” Our co-operation with FinMeas Ltd’s experts has run
smoothly. They continuously develop their systems and
take strong account of customer needs.”
Kari Äikäs, Project Manager – Saarnio & Riekkola Oy
18. CASE VATTENFALL:
”Because of FinMeas’ alarms we can sleep our nights
peacefully” – Kari Niemelä - Vattenfall
Baseline
•Need for monitoring the
possible inner erosion of
Pamilo dam and to
minimize the risks caused
because of it
Our solution
•Automatic pore pressure
measuring systems to monitor
dam’s safety
•The measurements started in
2011 and continue still
Result
•Real time and exact
information of the dam’s
situation and functioning
•Measuring sensors
detect inside the
structure that what
cannot be seen from the
outside
•Because of alarms there
is more time to react if
changes occur
”Because of alarms we can sleep our nights peacefully. They
give us time to react so that we can find the reason for the
possible changes.
Especially good with FinMeas’ service is that the dam’s
situation can be seen in real time.”
Kari Niemelä - Vattenfall
19. Baseline
•12 meters deep pit;
distance one meter from a
shopping center and three
meters from a block of flats
•A challenging site; need
for optimal planning and
monitoring
Case Skanska
Measurement saves on costs and improves
safety
Our solution
•Automatic inclinometers
monitoring displacements in
the support walls of the pit
•Automatic anchor force
measurements
•The measurements started in
2013 and ended in 2014
Result
•Use of measurements
has allowed a reduction
by one third in the
number of anchors used
in IsoKristiina support
walls; saving for over 200
000 euros
•Increased safety, direct
cost savings
” FinMeas was responsible for the support wall anchor force
and displacement measurements. These measurements
enabled us to plan and monitor our work more effectively on
this demanding site.” Tarmo Tarkkio – Skanska Infra Oy
20. CASE STOCKHOLMS HAMNAR:
Measurements ensure functionality of
critical structures
Baseline
•Ground movements
threatened the safety of the
harbour buildings
•A bored pile wall to stop
the ground movements;
need for monitoring its
movements in real time
Our solution
•Automatic inclinometers to
monitor the bored pile wall’s
effectivity
•Automatic measuring of
anchor forces
•The measurements started in
2015 and continue still
Result
•Real time information of
the bored pile wall’s
effectivity
•Measuring data shows
that the wall is working
well and the ground
movements have stopped
” FinMeas’ devices are reliable and the service is easy-to-use.
We have had a good co-operation. They are experts in their
branch and I am very pleased with our partnership.”
