Hydraulic shores prevent cave-ins by supporting the side walls of a trench by means of hydraulic pressure. BS EN 14653 is a European standard series applicable to manually operated hydraulic shoring systems for groundwork support.
BS EN 14653-2 is the second part of the multi-series, and specifies methods of calculation and test to assess the conformity of manually operated hydraulic systems for groundwork support whose performance is specified in EN 14653-1.
BS EN 14653-2 on manually operated hydraulic shoring systems assessment is useful for:
Manually operated hydraulic shoring systems comprise prefabricated equipment to support sheeting to the sides of excavations. BS EN 14653-2 covers two types of equipment whose adjustment is by hydraulic or a combination of hydraulic and mechanical means:
A variety of components exist which when assembled forms a full system. The instruction manual provides all the necessary information for the safe use of the systems.
The prefabricated components are used to make frame assemblies of different dimensions and structural capacities.
BS EN 14653-2 is frequently used in conjunction with supplementary equipment, e.g., knee braces and intermediate hydraulic bracing struts.
BS EN 14653-2 guidelines for trench excavation and building support contribute towards increased worker safety and efficiency of a properly installed system.
