Aid's compatibility with the domestic market remains undecided by the Commission.
In the ongoing construction of the canal in Langacker Street, a deviation in gradient during the first drive under Reitweg was encountered. This deviation, primarily due to inaccuracies in the initial surveying and alignment processes, as well as unforeseen ground conditions that affected tunneling precision, has caused challenges in the pipeline installation at Reitweg.
However, the construction team is taking proactive measures to improve accuracy for the next longer sections. These steps include:
- Enhanced Surveying Techniques: The team is employing more advanced and frequent geodetic measurements with high-precision instruments to continuously monitor and adjust the alignment and gradient during tunneling.
- Improved Ground Investigation: More detailed geotechnical investigations will be conducted ahead of tunneling to better anticipate ground conditions and adjust the drive parameters accordingly.
- Regular Calibration and Monitoring: Rigorous checks and calibration of the tunneling equipment and instruments will be introduced to reduce mechanical and operational errors.
- Real-Time Adjustment Protocols: The team is establishing real-time gradient monitoring and adjustment procedures, allowing them to correct deviations promptly as the drive progresses.
The collaborative team, which includes the commissioned firm Plate and the planning office H2P, is working diligently to rectify the issue and continue the pipeline installation. The start and target shafts for trenchless pipeline installation in Reitweg and Baerler Street towards Duisburg are complete, and the driving works for the trenchless pipeline installation have begun in the area of the new pumping station.
The sewer pipeline is being advanced towards the pumping station in the southern shoulder of Reitweg using open-cut construction. The drive for the pilot bore has crossed the carriageway from the northern to the southern side of Reitweg. The first drive under Reitweg did not achieve the planned gradient, but the improvements being made are expected to benefit the next stages of the pipeline installation in Reitweg.
It's worth noting that the canal construction works in Langacker Street have been completed. The road construction in Langacker Street will commence after the final integration of the drinking water pipeline in Reitweg. The ordnance clearance of the current pipeline section is planned for the 32nd week. All parties involved, including the city of Rheinberg and RAG, are collaborating to determine the reasons for the deviation.
The completion of road works in Langacker Street, including the new asphalt surface, is planned by August. The pilot bore will be enlarged to DN 400, and the final stoneware pipeline DN 400 will be installed. The collaborative effort aims to ensure the success of the pipeline installation and maintain the accuracy of the canal alignment for the subsequent longer tunneling sections.
- Despite the unexpected deviation in gradient in the pipeline installation at Reitweg due to factors such as initial surveying errors and ground conditions, the industry is leveraging advanced surveying techniques, improved ground investigations, regular calibration and monitoring, and real-time adjustment protocols to enhance the precision in the next longer sections, ensuring the success of the pipeline project.
- As the finance sector continues to support significant infrastructure projects like the pipeline installation, the energy sector stands to significantly benefit from these investments, especially in areas like Reitweg and Baerler Street towards Duisburg, where the project's success is expected to provide a more efficient and reliable energy distribution system.
