Abstract: Disclosed herein is 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.

Abstract translation: 这里公开了一种土壤流入防止装置，其中角形旋转开/关板适于通过打开止动件而在预定角度内倾斜，以防止开/闭板的后部开始过度降低 污水的流入量由于降雨而增加，从而在污水流入开始时防止土壤进入截流下水道。
