Concrete Pipe Trenching
Concrete Pipe Trenching
(OP)
We are designing a concrete pipe trench on an industrial site that will hold 2 24" Gas lines with 2 smaller gas lines running above them. 4 pipes total in concrete trench. One 24" gas line will be laid in the trench initially will the others to be installed with other phases. What would be the best design for this trench? I am thinking a grated top for the length of the trench (it will be partiall underground and above ground). If there is not a grated top and instead a fully enclosed trench it would be difficult to install the future lines. A grated top will pose some problems where the tench crosses the roadwAy with drainage considerations. Anyone have experience with this? Thanks

To lift the covers, you put a chain or cable through the loop and attached to a backhoe bucket, forklift tongs, etc. and guide them out using this mechanical equipment.
You will need to look at some details, such as how the pre-cast covers can properly fit on top of the main concrete trench. If cars or pedestrians are to travel over the top of the trench, then the lid design must be strengthened and the lifting loop imbedded below the travel surface.
If the top of the trench is buried below ground, it is a good idea to tie some nylon rope to the top of the cover. That way, the backhoe operator who is excavating for the trench in the future will will have some indication when the concrete cover is nearby. I have seen backhoe drivers come down hard on something he is looking for - and break whatever he is trying to uncover. A rope above your concrete vault will stop that.
