Abstract

The invention discloses a portable power-free communication manhole efficient ventilation method. The method comprises following steps: opening the communication manhole first before a constructor goes down the manhole for operation; checking whether harmful ingredients are contained in the manhole or not by using a gas detector; using a portable communication manhole efficient ventilator to discharge underground toxic harmful gas; using a toxic harmful gas detector again to make sure it is safe or not; allowing the operator to go down the manhole after safety is determined. The method has high ventilation efficiency and allows the toxic harmful gas to be quickly and forcibly discharged; two optional working modes are provided, and the toxic harmful gas can be automatically discharged using natural wind and also by manual operation.
