方形钢筋混凝土化粪池,管池的池型呈切角方形,数个管池上下相接组成单元化粪池,数个单元化粪池在同一平面上串联或并联组成组合式方形钢筋混凝土化粪池,位于组合式方形钢筋混凝土化粪池的一个单元化粪池的上端管池壁上设有进水口与该进水口相邻的该管池壁上和依次相邻的上端管池壁上的各单元化粪池之间设有贯通口,后一单元化粪池的上端管池壁上设有出水口,进水口高于贯通口,出水口与贯通口齐平或低于贯通口Square reinforced concrete septic tank, the tank type of pipe tank is chamfered square, several pipe tanks are connected up and down to form a unit septic tank, and several unit septic tanks are connected in series or in parallel on the same plane to form a combined square reinforced concrete septic tank, A water inlet is arranged on the upper pipe wall of a unit septic tank of the combined square reinforced concrete septic tank, and a through hole is arranged between each unit septic tank on the pipe tank wall adjacent to the water inlet and the upper pipe tank wall adjacent in turn. A water outlet is arranged on the upper pipe tank wall of the latter unit septic tank, and the water inlet is higher than the through hole, The water outlet is flush with or lower than the through hole  

三格化粪池模具，预制化粪池钢模具新型仅有一池型结构,用贯通口代替过水口和通气口,易标准化生产安装,生产安装简便,大幅度降低水泥用量,占地面积小,存污水体积大,各池壁之间接触面大,承压好,制造成本低。三格式化粪池钢模具一般使用在农村厕所改造工程中，100*100*150cm，180*100*90cm，中间带隔断，分成三节。为农村环境的基础建设提供了做出了突出贡献。

Three compartment septic tank mold, prefabricated septic tank steel mold, the new type has only one tank structure. The through port is used to replace the water outlet and vent, which is easy to standardize production and installation, simple production and installation, greatly reduce the cement consumption, small floor area, large sewage storage volume, large contact surface between tank walls, good pressure bearing and low manufacturing cost.
