Amberg Technology in SMP4 Exploratory Tunnel

Amberg Technologies has assisted the construction of the exploratory tunnel Saint-Martin-La-Porte Base Tunnel (SMP4), a 57km long French-Italian base tunnel which will, when construction is completed in 2022, be one of the longest railway tunnels in the world.

The tunnel will link Saint Jean de Maurienne in France and Susa in Italy running beneath the Alps and form the bulk of the Lyon-Turin high-speed railway link. The Lyon–Turin Link will run trains at operational speeds of up to 220km/h, with infrastructure shared by freight and passenger services.

SMP4 Exploratory Tunnel

The SMP4 Exploratory Tunnel will consolidate information garnered by an exploration conducted from 2002 to 2010 between the La Praz, Saint-Martin-la-Porte and Modane declines in France and the Maddalena decline in Italy. The new exploratory tunnel will be 9km long, with TBMs excavating from France to Italy. It will go on to form a key portion of the Base Tunnel.

The exploration is being undertaken to find out more about the subterranean environment and will utilise Amberg Control Software which enables a comprehensive 3D profile of the geologically sensitive area in real time.

Amberg are also providing heading guidance by way of Amberg Navigator tablet software, enabling tunnel crews to rely on pre-defined patterns in drill and blast operations. At certain points in the tunnel, convergences do not allow for drill and blast, which is where the use of Amberg Navigator’s Arch solution NATM, used in sequentially tunnelling, removes the need for a surveyor, although one was on-site during the course of the excavation for other purposes.

Surveyor Engineer Olivier Gauche said:

“The use of Amberg Navigator Tablet Software is a big benefit for personnel, enabling them to carry out simple, routine surveying task reliably, efficiently and independently.

“The Amberg Navigator tablet solution with the big screen allows us to see the 3D measured profile information clearly. Furthermore, positioning the instrument without knowledge of the control IDs is a plus and simplifies the workflow.”

Amberg Control Surveying in 3D enabled the evaluation of measured profile data, enabling the import and modification of profile data to take place in real time. The 3D DXF-reports to CAD software and generates a complete “as-built” model of the tunnel. Amberg also managed the control points, meaning that the control points can be adjusted according to new information, reducing 1000 control points on the database to 400, with an accessible history of each.

Olivier Gauche further observed that the use of the built-in axis calculator improved daily workflow, enabling work to be carried out in Heading Stationing or in 3D Tunnelmeter. With “the on-axis calculator in Amberg Tunnel calculates, for instance, the correct length of the conveyors belt, which follow the slope of the tunnel, efficiently.”

Railway and Tunnel Surveying

Whether it’s a subway tunnel in London, a hydroelectric plant on the Amazon River, the Gotthard Base Tunnel in Switzerland or a high-speed rail route in China: Construction projects of this magnitude are nothing unusual for Amberg Technologies AG. The Swiss company is one of the global leaders specializing in user-friendly railway and tunnel surveying solutions. Geophysicists and surveyors as well as software and hardware engineers at the headquarters in Regensdorf near Zurich design customized system solutions for georeferenced data capture and processing in infrastructure installations. The company offers its customers field-proven products as well as customer-specific services for railway surveying, tunnel surveying and tunnel seismics. Amberg Technologies belongs to the Amberg Group along with Amberg Engineering AG, Amberg Loglay AG and VSH VersuchsStollen Hagerbach AG and has grown steadily since it was founded in 1981. Today, Amberg Technologies is the global market leader in the area of railway and tunnel surveying and offers its products and services through a network of more than 30 sales partners in over 40 countries. Customers include railway companies and construction companies as well as engineering firms, surveying agencies and universities. A well-established network of local service partners in all markets guarantees customers the Swiss quality and reliability to which they are accustomed. [gallery ids="11814,11815,11816"]

Railway Surveying Equipment

Amberg Rail system solutions meet the most demanding needs in modern railway surveying and consist of the modular hardware, the GRP System FX and the customized, application-specific software platform, Amberg Rail 3.0. When faced with diverse, high-level surveying requirements in the areas of construction and maintenance of slab track and ballasted track, as-built survey of existing lines, clearance analysis, Amberg Technologies is the reliable partner of choice for the international railway industry.

Track Geometry Measuring Equipment

The well-tried railway surveying system GRP System FX is extended with the new Amberg IMS 1000 and Amberg IMS 3000 system configurations – the first and only one-trolley long-chord system. The Amberg IMS systems measure the inner and outer track geometry of ballast tracks and slab tracks using a new, high-performance sensor – the Inertial Measurement Unit (IMU). The employed IMU consists of 3 gyroscopes, 3 acceleration sensors and an on-board computer. Amberg IMS enables our customers to reduce time, manpower, costs and complexity in managing work.

Tunnel Surveying Systems

The tunnel surveying systems from Amberg Technologies support tunnelling in all construction phases. The system solutions under the umbrella name of Amberg TMS combine precise measuring instruments with task-specific software and today are an indispensable tunnelling equipment component. Significant improvements in efficiency are realized especially in tunnel setting out, tunnel profile measurements, geotechnical analysis and as-built tunnel analysis.

Railway and Tunnel MobileMapping

Railway and tunnel surveying, GeoMonitoring, MobileMapping, inspection and conservation of evidence – customers from very diverse segments of the infrastructure industry make use of the services provided by Amberg Technologies. In addition to the services themselves, product training and project support for all system customers is also offered with a primary focus on Switzerland, but also internationally.

Tunnel Seismic Prediction

Accurate knowledge of the geological situation enables early recognition of risks and timely initiation of logistical measures. The proven TSP System forecasts the ground conditions at the tunnel face reliably and continuously, making tunnel engineering more calculable in terms of safety, faithfulness to deadlines and cost efficiency."
