The invention provides a double-layer basketwell cover, which comprises an outer cover, an inner cover and a bottom bracket, the outer cover is a solid cover, the inner cover is a hollow grid structure made of steel bars, and the outer cover and the inner cover are connected by the bottom bracket; the vertical section of the bottom bracket is inverted T-shaped, the upper end is semi-movable connected with the outer cover, and the outer end of the lower end is protruded in the inner wall of the basketwell, and the inner end of the lower end is located in the inner cover. Bottom. The outer cover and inner cover of the double-layer basketball well cover are set at the same time at the basketball well head. Even if the outer cover is lost, the reinforced hollow grid structure of the inner cover can also provide certain filtering effect for pedestrians or large obstacles on the road without hindering the flood discharge of the road surface, avoid pedestrians stepping out or being washed into the basketball well, and play a protective role for the equipment in the basketball well.
【技术实现步骤摘要】
一种双层窨井盖
本专利技术涉及环卫设施制备领域,特别地,涉及一种双层窨井盖。
技术介绍
随着城市建设的发展,道路下配备的供水、供电、污水排放、通讯管线越来越多,而这些管道均设置有众多与地面相通的窨井,并设有井盖。但现有井盖多为直接放置在窨井口,无固定设施;且多为单层。当井盖出于各种理由遗失时,则在路面上留下了众多不安全隐患,不仅造成道路表面不平整,堆积道路表面垃圾,甚至成为路人杀手。
技术实现思路
本专利技术目的在于提供一种双层窨井盖,以解决井盖遗失后窨口井无保护措施的技术问题。为实现上述目的,本专利技术提供了一种双层窨井盖,包括外盖、内盖和底托,所述外盖为实心盖,所述内盖为钢筋制成的空心网格结构,所述外盖和所述内盖间通过所述底托连接;所述底托的纵截面为倒T形,上端与所述外盖半活动连接,下端外侧突出于窨井内壁中,下端内侧位于内盖底部。优选的,所述底托下端内侧设置弯钩,所述弯钩与所述内盖边缘大小相适配,所述弯钩穿过内盖边缘内侧直至其尾端位于所述内盖顶部。优选的,外盖内侧设置有加强筋。优选的,所述内盖为空心九宫格结构。优选的,所述底托外侧面为向窨井内壁方向倾斜的斜面。优选的,所述底托外侧面上设置若干齿状突起。优选的,所述内盖厚度为2-5cm。优选的,所述空心网格结构中单根辐条的宽度为2-5cm。本专利技术具有以下有益效果:1、双层安全防护:外盖和内盖同时设置在窨井口,即使外盖遗失,内盖的钢筋空心网格结构,也能在不妨碍路面泄洪的前提下,对路面行人或大的障碍物提供一定的过滤作用,避免行人踏空或者被冲入窨井,并对窨井内设备起防护作用;2、不易滑脱:外盖通过底托与窨井壁连 ...
