Concrete Block Pipe Support
Concrete Block Pipe Support
(OP)
I am after a detail of a concrete block pipe support for a DN600 aboveground pipe in a mine environment. I have the dtails of the strap and HD Bolts. I am unsure of the reinforcing steel/concrete strength details for the block.
I only ask because this detail is but one of many items in this project. The rest I have covered. I know the first instinct is to tell me to go and hire someone. Well that isnt going to happen.

If you want to be done with it, the rule of thumb is #8 at 12" c/c both ways, both faces, with 2 tie wraps at the top, but it would be somewhat irresponsible to tell you that without further details. That would usually not be an overwhelming cost to the project, allow you to do the detail and get on with the money making aspect of things. Use a steel plate on the top of the concrete, embedded in the leveling grout. Grout is usually 2 to 3" thick on top of the rough concrete level. You may want a pipe base plate with jacking screws on top of that, if attaining the precise bottom of pipe elevation is important.

Soil is run of mine waste compacted for stability with a sheeps foot roller to an Rd 95%. Soil tests are carried out.
The pipe is fully welded and located on the face of the soil. The stress analysis for two conditions ambient temperature at pressure or 80C when empty and under solar radiation. Pipe movement in the axial direction is limited by embedment in soil under roads. Lateral movement is not anticipated. Supports will be partially buried in the soil to prevent lateral movement.
The pipe support is to give a nominal 400mm off the soil surface.
Rather than a steel plate offering a flat surface the type used provides a 120 degree continuous support. A 6mm membrane is installed under the pipe and apipe strap fitted to keep the support and pipe as one.
I will get a structural engineeer to check what I come up with.

Puddle about 20cm of concrete in the bottom of the 1m square hole to act as a footer, and make sure that the radial turned out bars are in this pour. After the footer pour the tube full and chamfer the top edge of the concrete. Fairly simple, fairly cheap, very sturdy.
