Disclosed herein in a soil inflow prevention apparatus in which an angular- rotation opening/closing plate is adapted to be inclined within a predetermined angle by virtue of opening stoppers to prevent a rear portion of the opening/closing plate from being excessively lowered in the beginning that an inflow amount of sewage increases due to rainfall, thereby preventing soil from entering an intercepting sewer in the beginning of an inflow of sewage.

L'invention concerne un appareil permettant d'empêcher un afflux de terre dans un collecteur général, appareil caractérisé en ce qu'une plaque d'ouverture/fermeture, à rotation angulaire, est adaptée de manière à être inclinée d'un angle prédéterminé, en ce que des butées d'ouverture empêchent qu'une portion arrière de ladite plaque d'ouverture/fermeture soit abaissée excessivement au commencement, afin qu'une quantité de déversement des eaux d'égout augmente en raison de chutes de pluie, empêchant ainsi la terre d'entrer dans un collecteur général en début de déversement d'eaux d'égout.
