2) The transverse pipe passes through both sides of the fireproof partition wall and the firewall. 3) When the horizontal pipe is connected with the pipe well or pipe hole inner riser, it passes through the penetration part of the pipe well or pipe hole. 2. The drainage riser of public buildings should be located in the pipeline well, when the area of the pipeline well is greater than 1m2, every 2 or 3 layers should be combined with the sealing of the pipeline well to take anti-flame protection measures such as fire arresting rings or fireproof casing.
3. The fire resistance limit of the fire arresting device should not be less than the fire resistance limit of the building structure at the penetrating part.
