The invention relates to the technical field of rail transit, and discloses a sewer well lid for an urban road. The sewer well lid comprises a prefabricated steel member, wherein the middle part of the prefabricated steel member is movably sleeved with a lid body, four groups of upper drainage holes which are arranged in an equal circumference mode are formed in the upper part of the lid body, and a cavity is formed in the lid body. Through the arrangement of a floating plate, a floating ring and a cam limiting rod, when water is accumulated on the road surface due to more rain, the accumulated water enables the floating plate to ascend under the action of buoyancy, so that the drainage of the accumulated water on the road surface can be accelerated; meanwhile, a supporting rod can be driven to ascend synchronously in the ascending process of the floating plate, so that a rotating body rotates by a quarter of a circumference, and a connecting rod is propped against the protruding part of the side surface of a cam; and an ejector rod is ejected out, so that the limiting rod slides towards the inner side, a through hole coincides with a through hole, a large amount of accumulated water entering from a water inlet can be discharged, the problems that the drainage efficiency is low and the speed is low due to the fact that only a lower drainage hole is used for drainage are solved, and normal passage of people is ensured.
本发明涉及轨道交通技术领域，且公开了一种城市道路用下水井盖，包括预制钢构件，预制钢构件的中部活动套接有盖体，盖体的上部开设有四组等圆周排列的上排水孔，盖体的内部开设有空腔。通过浮板、浮动环、凸轮限位杆的设置，使得当下雨较多而导致路面产生积水时，积水将使浮板在浮力作用下上升，可以加快路面积水的排放，同时在浮板上升的过程中会带动支撑杆同步上升，使得转动体旋转四分之一圆周，从而使凸轮侧面凸出的部位将连接杆抵死，将顶杆顶出，使得限位杆向内侧滑动，使通孔与贯穿孔重合，能够将从进水口进入的大量的积水排出，避免出现仅通过下排水孔排水，排水效率低，速度慢的问题，确保人们能够正常通行。
