Barrier Plate Design Options
Barrier Plate Design Options
(OP)
I have a project in which a section of a concrete barrier (+/- 10') will be cut out for a tench to replace a hydrant lateral.I have another project that will eventually replace the barrier in its entirety but that won't be for another 6 or months or so after this trenching project ends. I have to put in a temporary barrier plate or possibly fill with concrete. What is the design procedure for a temporary barrier plate and, is there a better option?
Thanks
Thanks

Attached is a detail for a closure plate for concrete barriers; I'll post another one also. These have been used on interstates in NYC BUT they're only good for 5-feet.

Reconstruct the barrier.
Backfill the trench within the median, put in a 10' piece of temporary concrete barrier, sandwich it between two thrie beams anchored to the permanent barriers.
Backfill the median and install temporary concrete barrier on both sides of the permanent barrier. You'll need flared sections at the leading edges. However, if the median is only 18" in your work area you'll need to restripe the lanes.
Heavy post guardrail.
If you're on a parkway, you might be able to get away with thrie beams or box beams bolted to the permanent barrier.
Look at Chapter 10 of the NYSDOT HDM Link
Out of curiosity, can you disclose what road the project is on?
