Ventilation system arrangement structure during construction period of underground cavern of hydropower station
The invention discloses a ventilation system arrangement structure during a construction period of an underground cavern of a hydropower station. The ventilation system arrangement structure mainly consists of a main plant, a main transformer chamber, a tail water tube bulkhead gate chamber, a tail water pressure-regulating chamber, a tail water tunnel, a road tunnel and a tail regulating ventilation hole, wherein the main plant, the main transformer chamber, the tail waste tube bulkhead gate chamber, the tail water pressure-regulating chamber, the tail water tunnel and the road tunnel are separated by air inlet and ventilation channels; air inlet channels are arranged by combining with construction branch holes; and a special ventilation system arrangement structure for an air exhaustion adit and an air exhaustion vertical shaft is arranged on the top of each large cavern. The ventilation system arrangement structure has the beneficial effects that: ventilation and fume removal effects are good; discharge of a great deal of polluted air generated by operations such as drilling, blasting, deslagging and the like in a construction process can be guaranteed; and guarantee is provided for health and safety of a constructor.
