According to the floor height of the ceiling, the manhole on the ceiling can be divided into two ways: accessible and non accessible. When using the accessible manhole, there is no great requirement for the layout position of the manhole, because the later maintenance is to climb into the ceiling directly through the manhole and walk inside the ceiling for maintenance.
If the manhole cannot be used, it is necessary to arrange the manhole in a radius of about 500mm around the equipment point in strict accordance with the equipment point on the mechanical and electrical drawing; because when people's half body enters the manhole, they can reach the maintenance equipment and carry out equipment maintenance.
