Description
|
|
Piperoof grouting system OCTOPUS is a system for registration of pressure and
quantity for processes of the injections of concrete in tunnelling operations.
Under difficult geological conditions (e.g. granular soil) tunnels are built
depending on the geological conditions, requiring various supporting measures
for construction. Amongst others, piperoofs and jettings, injections and
drawndowns are widley used.
Tunnel driving by the use of a piperoof ensures protection by means of pipes
of a length up to 20 meters, that are driven into the ground preparative and
then secured by the use of shotcrete and, if applicable, supported by steel archs.
|
|
 |
The system for drill holes, injections, measurement and registration was
specifically developed for tunnelling and supports fully automated registration
of all data resulting from a process of injection. Control of pumps allow for
assigning any drill hole to certain pumps, if multiple pumps are available.
The systems turns on pumps and terminates them, as soon as any creiterion for
terminations is matched.
|
|
|
All measurement values for the actual pressure of injection, actual velocity
of flow and aggregated quantity of concrete used is monitored and recorded
according to time, injection and drill hole for having available all relevant
data for later evaluation and analysis.
All data recorded are stored on a harddisc for industrial use an and
additionally on a media (PCMCIA) for easy transfer to other systems.
|
The graphical user interface of the analysis part of the system, in combination
with a 15" TFT-touchscreen, guarantee easy operation. All relevant data from
injection processes can be visualised on summary charts.
Documentation is provided for each drill hole and aggregated for the pipe
roof in general.

Features
|
|
- Dust-proof design with specific protection for rock slide and splash water.
- Twofold data storage on an industrial harddisc and additional media.
- The three independent software components - configuration, registration/control and evaluation/analysis/documentation - are each optimised for requirements of other components.
- Preparation and configuration of piperoofs in the office.
- Data recording on site in the tunnel.
- Analysis and documentation in the office.
- Registration interface with graphical user-interface and TFT-touchscreen.
- Control of up to two pumps.
- Free assignment of drill holes.
- Simple and easy to use set-up of the system through three independent parts of software.
- Easy operation on site in the tunnel with realistic display of the piperoof.
- Self-controlled termination of pumps when reaching criteria for termination.
- Field-tested in tough tunnelling operations.

Piperoof configuration
|
|
|
|
This part of the software allows the construction site management for defining
the piperoof, threshold values and criteria for termination. Further all data
required for proper documentation is set-up in this part of the system:
- Geometry of piperoofs.
- Number and type of injection pumps.
- Criteria for termination for the piperrof in general and additionally
for each drill hole.
- Type of cement and water/cement-value.

Registration and control
|
|
|
|
Ease of use and lifelike design (what you see is what you get) distinguish
this part of the application. Easy assignment of drill hole to an injection-pump
in case of multiple pumps available.
Self-controlled termination of pumps when matching criteria for termination.
- The layout on the screen corresponds to the piperoof.
- Automated control of pumps of various manufacturer.
- Recording of any sensors for pressure and flowrate.
for each drill hole.
- Reason for termination is recorded in case of manual termination.

Analysis and documentation
|
|
|
|
Automated generation of reports including all relevant data, summaries and
charts. The open data model allows for easy export of data for analysis tools
and office applications.
The presentation of data includes both values for each drill hole and
aggregated data for the pipe roof in general, including gross and net
turn-on times of pumps.
- Automated generation of piperoof documentation.
- Charts for pressure and flow-rate and reference of records.
- General presentation of the piperoof, grouted quantities of
cement and turn-on times of pumps.
- Data interface for export of data to analysis-tools.
