Diaphragm walls using trench cutter in confined space-Video

Video Transcription

Video Summary

The presentation explored diaphragm wall construction in confined urban sites, where limited space, difficult ground, logistics, safety, and environmental requirements challenge productivity. Diaphragm walls are well suited to these projects because they can reach great depths, work in varied soil and rock, and cause relatively little vibration. Compact, adaptable equipment—including low-profile carriers, turning devices, and increasingly electric machines—helps address site constraints. Case studies from Hong Kong, Paris, and a German dam showed how specialized equipment and planning enabled construction under height, width, hard-rock, and winter-weather restrictions. The speaker concluded that these challenges can be managed with appropriate methods and equipment.
