Diaphragm walls using trench cutter in confined space-Video 2

Video Transcription

Video Summary

The presentation examines diaphragm walling for confined-space and inner-city projects, driven by rapid urbanization and demand for deeper infrastructure. Success depends on careful planning, site logistics, adaptable equipment, and adjustments for safety or unforeseen conditions. Diaphragm walls suit varied soils and rock, reach considerable depths, and create little vibration—useful near existing buildings. Compact, height- or width-restricted equipment and turning devices enable work in tight spaces; electrification may improve environmental performance. Case studies from Hong Kong, Paris, and Germany demonstrate solutions for restricted access, hard rock, and challenging weather, showing that these constraints can be managed with appropriate methods and equipment.
