Trench Boxes Manufacturing & Supply

ESC has fully developed its Trench Box Series (also known as Trench Shields) 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

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.
