PROPRIETARY TRENCH SUPPORT SYSTEMS

This technical note considers the trench support methods available and in use in the UK in 1978. For greatest safety support should be provided quickly and before any person enters a trench. The support methods generally available in the UK which meet this requirement are indicated. Some of the methods, particularly shields, are used to provide protection for people working in the trench in the event of ground collapse, rather than to provide support preventing collapse. When operators are experienced in the use of proprietary systems these are quicker than the standard sheeting, walling and strutting methods of support. The quickest and cheapest method when feasible is to maintain a near verticla sided open cut trench but this approach is associated with the greatest safety risk. /Author/ /TRRL/
