In a pit that is 10m long and 9m wide, two underground tanks are installed; without filling it with sand, how should the factory’s air ducts be arranged?

Two light and heavy crude oil tanks with dimensions of φ3000×6000 mm have been installed. Now, it is necessary to arrange air supply pipes for factory ventilation, in order to blow away the gas inside the pit before workers go down to conduct inspections. Are there any design principles regarding such air supply pipes? Thank you
It is recommended to install two axial flow fans on each side, with the inlets connected to the bottom of the pit
How about using an axial flow fan or compressed air? Just perform replacement before operating
I want to keep it simple now: use pipes in the Lagun style and have someone go down there and open the valves to blow air in, thereby replacing the air inside the pit
It’s been decided to use compressed air; mainly, I want to see how these pipes should be arranged
Four pipes running down along the perimeter of the pool wall will suffice
It’s not like coiling it back and forth several times with holes punched in the coil, right?
Compressed air can be considered for use, and the piping system can be similar to the aeration devices used in water treatment.
That would be too troublesome; as long as there is compressed air, a pipe with a diameter of dn10 will suffice
Do you have any regulations regarding the spacing between the coils?
