Abstract

Un ensemble de couvercle de trou dhomme, lequel ensemble est configuré de façon à se comporter en soupape de détente lors dun événement dexplosion, souvrant de telle sorte quun fluide, tel que de lair ou des gaz explosifs, peut être évacué à partir dune zone souterraine. Lensemble de couvercle de trou dhomme peut comprendre un couvercle de trou dhomme et un cadre, et peut être configuré de façon à limiter un mouvement du couvercle de trou dhomme par rapport au cadre en réponse à une pression accrue sur le couvercle de trou dhomme. Dans un mode de réalisation, le couvercle de trou dhomme peut comprendre des pattes ayant des surfaces en angle aptes à centrer ou à guider sensiblement le couvercle de trou dhomme dans le cadre tandis que le couvercle de trou dhomme se déplace de façon à relâcher une pression. Dans un autre mode de réalisation, une ou plusieurs pattes peuvent coulisser à lintérieur du couvercle de trou dhomme de façon à permettre de configurer le couvercle de trou dhomme entre un mode de maintien et un mode de retrait.
