Municipal drainage system
The invention discloses a municipal drainage system, and belongs to the technical field of urban water supply and drainage. The municipal drainage system comprises a main drainage pipe, a sewer pipeline and a maintenance pipeline, wherein a rain grate is arranged at the upper end of the sewer pipeline; a well lid is arranged at the upper end of the maintenance pipeline; two hinge seats are arranged at the bottom of the well lid; an L-shaped hook is hinged to each hinge seat; a connecting rod is connected between the two hooks in a sleeving manner; lantern rings are fixed at the two ends of theconnecting rod; the lantern rings at the two ends are arranged on the two hooks in a sleeving manner correspondingly; a circular ring is fixed in the middle of the connecting rod; an ejector rod penetrates through the circular ring; a floating ball is fixed at the bottom of the ejector rod; in addition, a limiting ring is fixed on the inner wall of the maintenance pipeline; an impurity removal mechanism and a water return prevention mechanism are arranged in the sewer pipeline. According to the municipal drainage system, the potential safety hazard caused by the fact that the well lid is opened by flushing during rainwater backflow can be prevented; and in addition, the impurity removal mechanism can effectively reduce sediments in the main drainage pipe, reduce the dredging frequency andsave the labor cost; the water return prevention mechanism can prevent rainwater backflow at a low-lying position and prevent water accumulation on a road surface.
本发明公开了一种市政排水系统，属于城市给排水技术领域，其包括主排水管、下水管道和维修管道，其中，下水管道上端设有雨篦子，维修管道上端设有井盖，井盖底部设有两个铰接座，每个铰接座上均铰接有L形弯钩，两个弯钩之间套接有连杆，连杆两端固定有套环，两端的套环分别套在两个弯钩上，且连杆中间固定有圆环，圆环内贯穿有顶杆，顶杆底部固定有浮球；此外，维修管道内壁固定有限位环，下水管道内设有除杂机构和防反水机构；本发明能够防止雨水反流时冲开井盖，造成安全隐患，此外，除杂机构可有效降低主排水管内的沉积物，减少疏通次数，节省人力成本，防反水机构可以防止低洼处雨水反流，防止路面积水。
