圆柱体削球形沼气池,是目前我国农村推行的主要池型之一。但这种池型,在实际施工过程中,经常会碰到两个问题:①由于埋设深度都在2米以上,在高水位地区建池,施工较麻烦。②由于池墙紧贴在砂石土层,池墙挖方和施工,难度大,用工多,特别是遇有砂质含量较多的土层,池墙易塌方。为了避免上述问题,在保持水压式沼气池工作原理不变的条件下,对农村家用沼气池,因地制宜的取消圆柱体池墙部分,为了保持主池有一定的容积,采取扩大沼气池直径的办法,削球形池盖矢跨比,
Cylindrical cut ball-shaped digesters, is currently one of the major pool type in rural areas in our country. However, this pool type, in the actual construction process, often encounter two problems: ① Since the depth of 2 meters are buried in the construction of high water level pool construction more trouble. ② As the pool wall clinging to the gravel soil, pool wall excavation and construction, difficult, more labor, especially in case of sandy soil content more, pool wall collapse. In order to avoid the above-mentioned problems, under the condition of keeping the working principle of hydraulic biogas digester unchanged, in order to keep a certain volume of the main pool, it is necessary to expand the size of digester in rural household biogas digesters according to local conditions. Approach, cut ball-shaped pool cover-span ratio,
