When water under pressure is forced to change directions, such as at a bend, large forces exist that try to separate the pipe at joints. This virtual workshop will cover the design of two different types of measures to offset these large forces – thrust blocks and restrained joints. The design of thrust blocks is more complicated than the standard details that are often used and an appropriate understanding of the design parameters can avoid a catastrophic failure. The design for joint restraint requires an understanding of the resisting forces, an understanding of the calculations necessary to determine the length of pipe that needs to be restrained and knowledge of the different options available to provide appropriate restraint.
