Comparative analysis of damage to sewer rehabilitation coatings
E3S Web of Conferences, 2018 Technologies for the trenchless rehabilitation of pipelines using various types of coatings have been used for almost half a century. Considering that the assumed life expectancy of such renewed pipelines is 50 years, it will be necessary to assess their

Roadway Culvert Asset Management: Systematic Review and Future Research Directions
Advances in Civil Engineering, Volume 2025, Issue 1, 2025.Culverts are essential for the sustainability and safety of transportation infrastructure. Despite their significance, they are often insufficiently managed, leading to significant socioeconomic and environmental repercussions. This systematic review critically evaluates the current state of roadway culvert asset management (RCAM), focusing on ...

Evaluation of an Alternative Tunnel Support System to Build Shallow Metro Stations at Urban Areas
Advances in Civil Engineering, Volume 2025, Issue 1, 2025.Ground surface settlement is the most significant restriction when constructing shallow metro station tunnels in urban areas. The umbrella arch method (UAM) is generally applied as a tunnel support method. However, UAM becomes inadequate in some soil conditions, such as loose sand or soft clay.

Delayed pipe replacement halves environmental impacts but quadruples water loss
AWWA Water Science, Volume 6, Issue 2, March/April 2024.Abstract Scheduling pipe replacement is critical for water distribution systems (WDSs) when managing finances and water loss. WDS replacements are often delayed due to high immediate costs without considering long‐term environmental consequences. This study is the first to examine a real‐world WDS using a novel workflow transferrable to other WDSs that

Site Assessment of Multiple-Sensor Approaches for Buried Utility Detection
International Journal of Geophysics, 2011 The successful operation of buried infrastructure within urban environments is fundamental to the conservation of modern living standards. Open-cut methods are predominantly used, in preference to trenchless technology, to effect a repair, replace or ...

Shock and Vibration, Volume 2024, Issue 1, 2024.Measures should be taken to prevent the effects of vibration caused by dynamic loads of machines. Research has shown that trenches can effectively reduce vibrations caused by machine foundations. It has been determined that the open trench provides the best performance against vibration, but it is not practical due to operational limitations ...
