Secondary drainage pipe network for shared toilet

A shared toilet secondary drainage pipe network relates to the technical field of building water prevention and drainage and comprises drainage pipe networks distributed on the same floor and communicated with all toilet sedimentation tanks on the same floor, and filtering water inlet mechanisms arranged on water inlets, located in the toilet sedimentation tanks, of the pipe networks. The height of the drainage pipe network is lower than that of the original secondary drainage port, the lowest permeation hole of the filtering water inlet mechanism is not higher than that of the original secondary drainage port, and the top of the filtering water inlet mechanism is lower than the sedimentation tank structural surface. The method has the advantages that the construction is simple, and all toilets on the same floor can share drainage mutually. 一种共享式卫生间二次排水管网，涉及一种建筑防排水技术领域，包括分布在同一楼层处，且与同层所有的卫生间沉池连通的排水管网、设置在管网的位于卫生间沉池内的进水口上的过滤进水机构，排水管网的高度低于原有二次排水口的高度，过滤进水机构的最低渗透孔不高于原有二次排水口，过滤进水机构的顶部低于沉池结构面。本发明具有施工简单，能实现同层所有卫生间能互相共
