Can cable trenches be used together with direct burial?

As the title suggests, can an 800*1000 cable trench be used together with an 800*1000 direct-burial trench? I would appreciate it if you could offer your guidance

Mm-hmm, those with bellows; the distance between them is 10 centimeters. It’s not certain at the moment; perhaps it’s to save costs that the 17 cable circuits are buried in cable trenches. But after branching off 8 cables at a certain point, is it okay to bury the remaining 8 directly?
Theoretically, process pipes are not allowed in cable trenches; however, if sufficient distance is maintained and the cables can be buried directly, there should be no problem.
So once it’s chosen, can only cable trenches be used from then on? Because if cable trenches are used for everything, it would be too expensive. However, using direct burial does not comply with the specifications in the atlas, as there are 18 cables coming out, with the number decreasing one by one afterward
It seems to refer to two cable trenches: one for directly burying cables, and the other being a regular cable trench. Cables are laid in the regular cable trench first, and the remaining cables are buried directly. I wonder if it’s a power cable or a signal cable? It seems unsafe to bury the power cable directly in the ground.
Does anyone know what the safe distance between cables, which are laid in galvanized steel pipes buried in trenches, and oil transport pipelines at gas stations, which are also laid in trenches, should be?
