Description

一种多功能市政用井盖A multifunctional municipal well cover

技术领域technical field

本实用新型涉及市政相关技术领域,具体来说,涉及一种多功能市政用井盖。The utility model relates to the technical field of municipal administration, in particular to a multifunctional municipal well cover.

背景技术Background technique

随着城市建设的快速发展,市政工程对城市生存和发展的影响也越来越大。而其中排水、排污系统对居民生活影响很大,所以需要定期对其管道进行清理,如果处理不及时,一旦发生暴雨天气,发生管道阻塞,将会对居民生活造成严重不便。由于落叶及路面的各种垃圾会随雨水流进排水井,其进入排水井后会累积粘结。除了落叶、塑料袋等体积较大的垃圾,各种淤泥杂物也会在在排水井底部淤积。工人清理这两类垃圾时都需要人工下井清理,这样劳动强度大,环境恶劣,清理效率很低。With the rapid development of urban construction, the impact of municipal engineering on the survival and development of the city is also increasing. The drainage and sewage systems have a great impact on the lives of residents, so the pipes need to be cleaned regularly. If the treatment is not timely, in the event of heavy rain, the pipes will be blocked, which will cause serious inconvenience to the lives of residents. Since fallen leaves and various garbage on the road will flow into the drainage well with rainwater, they will accumulate and bond after entering the drainage well. In addition to large-scale garbage such as fallen leaves and plastic bags, various silt debris will also accumulate at the bottom of the drainage well. When workers clean up these two types of garbage, they need to manually go down to clean up, which is labor-intensive, harsh environment, and low cleaning efficiency.

而现有路面上有许多井盖,而一个较大的作用就是排水,但是一般的井盖都只有两个孔,很容易就被道路上的垃圾和积起来的土灰所遮盖,使得排水不通畅,而还有部分管线井盖由于内部长时间的污泥进入,使得井盖的排水能力变差,此外现有井盖的功能单一,针对以上问题我们提出一种多功能市政用井盖。There are many manhole covers on the existing road, and one of the major functions is drainage, but the general manhole covers only have two holes, which are easily covered by the garbage on the road and the accumulated soil ash, making the drainage not smooth. However, some pipeline manhole covers have poor drainage capacity due to the long-term internal sludge entry. In addition, the existing manhole covers have a single function. In view of the above problems, we propose a multi-functional municipal manhole cover.
