Tire-derived aggregate (TDA) has been used successfully as a backfill soil to reduce the applied stresses on buried steel pipes. The preceding study, however, paid no attention inspecting TDA efficiency of concrete pipes subjected and traffic loads. In addition, it is not clear how material, loading, burial depth, road section affect pipe-bending moment. Therefore, this paper examines in reduci...

The tectonic fault poses a great threat to buried pipe segments. Buckling or rupture of pipes will ensue due large strain induced by continuously increasing movements. In this study, reliability-based methodology is conceptually proposed for designing new assessing existing installed in areas. Uncertainties associated with the influencing factors structure and seismic loading (fault displacemen...

ground penetration radar (gpr) as a nondestructive method for identifying underground objects has been successfully applied to different fields of science such as geotechnical investigations, oil and gas exploration, geology, pipe detection and archeology investigations. metallic and nonmetallic objects can be identified by this method.  the depth of penetration is dictated by the gpr antennas....

High-density polyethylene pipes (HDPE), crossbonded polyethylene pipes (PEX) and polyvinyl chloride (PVC) pipes for drinking water were tested with respect to migration of volatile organic components (VOC) to water. The odour of water in contact with plastic pipes was assessed according to the quantitative threshold odour number (TON) concept. A major migrating component from HDPE pipes was 2,4...

Decarbonisation of heating is essential to meet national and international greenhouse gas emissions targets. This will require adoption a range solutions including ground source heat pump district technologies. A novel route these includes dual use buried infrastructure for transfer storage in addition its primary function. Water supply wastewater collection pipes may be well suited thermal ene...
