27 Thrust Restraint Design for Buried Piping WSSC Water
In a pressurized buried pipeline such as a water main or sewage force main, thrust forces act on the pipe where changes in fluid velocity, changes in pipe size or changes in pipeline direction REDUCERS The unbalanced force is generated by the pressure acting on the difference in cross sectional area between the large and small side of the reducer This may be opposed by THRUST RESTRAINT DESIGN OF DEAD ENDS, VALVES, REDUCERS, 2021年4月27日 A thrust block is a concrete pipe restraint that prevents the mainline from moving by transferring pipe loads (mainly due to pressure thrust) to a wider loadbearing surface Usually, thrust blocks are provided for buried What is a Thrust Block?
