Thrust-Blocking PVC Pipe
- Water under pressure exerts thrust forces in piping systems at: changes in pipe size or direction, dead ends and valves.
- The design of thrust-blocking requires knowledge of the thrust generated and the bearing strength of the soil against which the thrust block will be placed.
- To be effective, a thrust block must:
- be placed against undisturbed or fully compacted earth.
- contact the fitting over a sufficiently large area so as not to create stress points on the fitting.
- have sufficient area on the soil to restrain the thrust without exceeding the bearing strength of the soil.
- Supply line 3″ in diameter and larger shall receive concrete thrust blocks. Please research specifications for amount of concrete to be used for thrust block.
This is used to form a 90 Degree branch from the mainline that is underground. Includes gaskets.
Available in 4″, 6″ & 8″ sizes
