This creation is about a kind of dirt channel on the bed of pigsty,It means that there is a dirt channel at the bottom of the pigsty bed formed by multiple cambers or multiple cambers or multiple slopes,A V-shaped ditch is arranged at the lower end of the dirt channel,On the top of the side wall of the V-shaped ditch is a vertical accumulation wall,The upper end of the accumulation wall is connected to the low point of the pigsty bed；According to it,The excrement mixed with pig urine and feces,It will flow gently down the curved or arched or sloped surface of the pigsty bed,And one by one attached to the accumulation wall of the sewage channel,The water contained in pig excreta is absorbed one by one to reduce outflow,And the attached pig waste is easy to dry and easy to swell organic material,And the accumulation wall is in a standing form,Then a certain thickness of pig excreta layer should be accumulated,It will automatically loose and collapse and be collected by dirt ditch,To achieve the effect and purpose of effectively reducing the generation and discharge of sewage.本創作係有關一種豬舍床面之污物渠道，係指在多弧面或多拱面或多斜面形成的豬舍床面低處設有污物渠道，該污物渠道下端設有V形狀溝渠，該V形狀溝渠側壁上端設有矗立的聚積壁，該聚積壁上端係連接於豬舍床面的低點；據之，該混雜著豬隻尿糞的豬隻排泄物，將會和緩的經該弧面或拱面或斜面的豬舍床面往下流送，並逐一附著積累在污物渠道的聚積壁，俾豬隻排泄物內含的水液被逐一吸收減少外流，而以該附著的豬隻排泄物為易乾和易膨鬆的有機材，及該聚積壁又呈矗立形態，則該積累一定厚度的豬隻排泄物層，將會自動鬆散崩塌並經污物溝渠被集收，達到有效減少污水產生和排放的效果與目的。
