Abstract:
A lightweight trench shield having side panels spaced apart by spreaders. Each panel has a core formed of a metal honeycomb with the core faces having a fiber in resin matrix layer thereon. The core density varies with regions proximate the spreader supports being increased to provide support for side loads. The spreader supports receive the ends of the spreaders and distribute the applied loads outwardly from the spreader via a mounting ring.
