Building roof direct sewage drainage rainwater pipe waterproof joint and construction method

LIU XIAOHUI

The invention discloses a building roof direct pollution discharge rainwater pipe waterproof joint and a construction method, and relates to the technical field of building joint waterproof devices. The roof structure comprises a roof structure layer, a waterproof coiled material is laid on the top of the roof structure layer, a heat preservation layer is laid on the top of the waterproof coiled material, a drainage pipe is fixedly connected to the interior of the roof structure layer, drainage openings communicating with the drainage pipe are formed in one end of the waterproof coiled material and one end of the heat preservation layer, and one end of the waterproof coiled material extends to the inner top of the drainage pipe. Through cooperative use of the driving assembly and the transmission assembly, the driving assembly is started to drive the mounting ring and the cleaning rod to rotate along the inner wall of the annular through groove, and meanwhile, the transmission assembly is matched to drive the cleaning rod to rotate, so that the cleaning rod is conveniently driven to rotate and move along the inner wall of the annular through groove; therefore, the cleaning rod completes cleaning of foreign matters accumulated on the outer side of the filter rod, blockage of the outer side of the filter rod is reduced, and the drainage efficiency of the device is improved.

本申请公开了建筑屋面直排污雨水管防水节点及施工方法，涉及建筑节点防水装置技术领域。本申请包括屋面结构层，屋面结构层的顶部铺设有防水卷材，防水卷材的顶部铺设有保温层，屋面结构层的内部固定连接有排污水管，防水卷材与保温层的一端均开设有与排污水管连通的排水口，防水卷材的一端延伸至排污水管的内顶部。本申请通过设置驱动组件与传动组件的配合使用，使得通过启动驱动组件可以带动安装环与清理杆沿着环形通槽的内壁进行转动，同时配合传动组件带动清理杆进行自转，以此便于驱动清理杆沿着环形通槽的内壁进行旋转移动，从而使得清理杆完成对过滤杆外侧堆积异物的清理，减少了过滤杆外侧的堵塞，提高了装置的排水效率。
