This report presents a design guide for thrust blocks to restrain the forces generated by changes in direction of fluid flow in jointed buried pressure pipeline networks. A step-by-step design approach is detailed. Refinements can be made by reference to detailed appendices which give a background to the underlying principles and theory.
The guidance given in this report is principally for thrusts up to 1000 kN, limiting both the pressure range and pipe diameters and, more importantly, the thrust block sizes. While the theory used is applicable in any circumstances, the design of large-scale thrust blocks requiring structural reinforcement, etc., is not covered.
