The invention belongs to the technical field of municipal roads, and particularly relates to a municipal primary-secondary well lid. The municipal primary-secondary well lid is provided with a primary well lid and a secondary well lid which is located on the upper portion and movably and fixedly connected into a whole, and the cross section area of the secondary well lid accounts for about one tenth of the cross section area of the primary well lid, so that the influence of the well lid on vehicles is effectively reduced, the well periphery bearing capacity is improved, sinking around a well is prevented, the well lid is prevented from being lost, and major potential safety hazards are eliminated; an anti-falling net is detachably connected in a cavity of a neck cylinder, so that the safety is ensured; the cross sectional area of the primary well lid located underground is about ten times of the cross sectional area of the secondary well lid, and the upper surface of the primary well lid is provided with grid ribs, so that base layer asphalt concrete and the primary well lid are firmly combined into a whole, the thickness of the grid ribs is gradually reduced from the vicinity of the secondary well lid to the periphery of the primary well lid, the strength and the impact resistance of the primary well lid near the secondary well lid are enhanced, the formation of diseases around the well is greatly reduced, the occurrence of traffic accidents is effectively avoided, and the stability and the comfort of driving are improved.
本发明属于市政道路技术领域，特别涉及一种市政用子母井盖，通过设置母井盖及位于上部活动固连为一体的子井盖，子井盖的横截面积约占母井盖横截面积的约十分之一，有效降低了井盖对车辆的影响，提高了井周承载力，防止了井周沉陷，防止了井盖丢失，解除了重大的安全隐患；通过颈筒空腔内设有可拆装连有防坠网，确保了安全；通过位于地下的母井盖横截面积约为子井盖的横截面积的约十倍，母井盖上表面设有方格肋，使基层沥青混凝土与母井盖牢固结合为一体，通过方格肋由子井盖附近至母井盖周边厚度逐渐减小，加强了子井盖附近母井盖的强度及耐冲击能力，大大减小了井周病害的形成，有效避免了交通事故的发生，提高了行车的平稳性和舒适性。
