Definitions

  • This invention relates to blocking flooding water from entering underground ventilation passages.
  • Ventilation ducts or shafts are incorporated into subway systems near stations to exhaust stale pushed air as the train nears a station and to pull in fresh outside air as a train leaves a station, Also reducing the "piston effect" of air being forced through the tunnels at high speeds by moving trains.
  • a ventilation duct communicates from an underground tunnel and terminates in a ventilation shaft structure below grade level that opens to the atmosphere at grade level such as a sidewalk where the opening is covered by a subway grating.
  • Subways have systems for handling water. When it rains, water runs down stairwells, onto platforms and thence onto tracks, and some gets in the ventilation systems through the surface gratings. Drains beneath the tracks pipe water to underground sumps in pump rooms next to the subway tracks. Pumps pull the water up to pressure relief manholes open to the atmosphere at street level; from there the water drains under gravity flow into city storm sewers. The problem is that in heavy rains, storm sewers are overwhelmed and flush water back into the streets, flooding the streets with water inundates sidewalk and pours down through subway gratings into the ventilation system thence into the tunnels and onto the tracks.
  • the pumping system can only return water to the flooded street; from there the water reenters the flood pool pouring into the ventilation system, defeating the pumping system as a means of controlling subway flooding.
  • the problem is especially acute in cities like New York and Lower Manhattan, which is low-lying, vulnerable to storm surges and dotted with grade-level gratings, stairwells and other points of entry for running water into the subways.

Abstract

Un appareil permettant la ventilation à travers un arbre de ventilation vers un conduit de ventilation souterrain communiquant de façon fluide à travers l'arbre de ventilation jusqu'à une ouverture atmosphérique de l'arbre et sur une menace d'inondation pouvant empêcher l'écoulement vers le bas de l'eau de surface dans le conduit de ventilation souterrain comprend un ou plusieurs panneaux articulés fermant un passage de ventilation entre le haut et le bas d'un support s'adaptant dans l'arbre pour empêcher une inondation. Les panneaux ont des poignées sur leur côté supérieur et des bras pivotants sur leur côté inférieur et peuvent être soulevés vers une position initiale verticale permettant la ventilation, à l'aide d'outils permettant d'atteindre des ouvertures de recouvrement de la grille sur l'arbre et de lever les poignées du panneau et après que les panneaux sont partiellement soulevés, à l'aide d'outils de portée pour engager et lever les bras en les pressant à nouveau sur les parois latérales pour exercer une force latérale sur la face inférieure des panneaux afin de compléter la rotation vers le haut en position de repos.
