多年来，检查井盖整体下沉、四周碎裂、井盖异响等问题在各地方的市政道路工程中都有不同程度的存在，这严重影响着道路的通行状况以及整体美观。

Over the years, the problems such as the overall subsidence of the manhole cover, the fragmentation around the well and the abnormal noise of the well cover have different degrees in the municipal road projects in various places, which seriously affect the traffic condition and the overall beauty of the roads.

以严谨著称的德国是如何解决这个问题的呢？德国的井盖从设计到管理都做了周密的考虑，井盖上都刻有城市的特色标志，即使在汽车反复碾压下也不会出现变形、裂痕，也不会产生噪声。此外，对使用场所、嵌入深度等也有规定。井盖上孔隙的大小按各地方每年雨水量决定，以便排水通畅。井盖下面都装有一个铁篮子，能截留住树叶等杂物。环卫工人只要定时打开井盖，把铁篮子钩出来，取走垃圾再将铁篮子复位就可以了。

How does Germany, a well - known German, solve the problem? Germany's well covers are carefully considered from design to management. The well covers are marked with signs of the city. Even when the car is repeatedly rolling, there will be no deformation, cracks or noise. In addition, there are also provisions for the use of places, embedded depth and so on. The size of the hole on the cover of a well is determined by the annual rainfall in each place, so that the drainage is smooth. Under the cover of the well, there is an iron basket, which can intercept the leaves and other sundries. As long as the sanitation workers open the well cover regularly, hook out the iron basket, take away the garbage and reset the iron basket.
