Trench Shield

ESC has fully developed its Trench Shields Series (also known as Trench Boxes) used as a two-sided excavation support system. It is a used as a temporary earth retaining structure which allows safe access to an excavation that has been cut vertically. Stability is ensured within the trench whilst providing a minimal excavation footprint for works to be carried out. This helps prevent any damage to nearby utilities and structures.

Design Verification

ESC completed third party verified structural calculations and professionally completed Finite Element Analysis of the proprietary ESC Trench Box design system, with special attention on the spreader connections to the panels. A wide range of loading conditions was simulated to verify the robustness of the system.

The international standards applied in the structural design included: EN 1990: Eurocode 0, EN 1991: Euro-code 1, EN 1992: Euro-code 2 and EN 1997: Euro-code 7.

A full scale component test with a third party independent witness was also completed to verify the design calculations with a focus on on the most critically loaded areas and potential weak points. A specially designed test rig was constructed to simulate the soil loads with a series of strain gauges situated throughout the trench panel structure to measure deflection of the structure under various loading combinations.
