球墨鑄鐵井蓋的應(yīng)用，在我們城市市政建設(shè)中起到了非常重要的作用，眾多不同型號的球墨鑄鐵井蓋產(chǎn)品的出現(xiàn)，為我們生活提供了幾大的便利。但是，球墨鑄鐵井蓋在應(yīng)用一段時間后會出現(xiàn)一個問題，那就是在使用中出現(xiàn)的下沉問題，下面小編為大家詳細介紹一下吧。

The application of nodular cast iron well cover plays a very important role in the municipal construction of our city. The appearance of many different types of nodular cast iron well cover products provides us with several great conveniences for our life. However, nodular cast iron well cover in the application of a period of time, there will be a problem, that is, in the use of the sinking problem, the following small series for you to introduce it in detail.

其中球墨鑄鐵井蓋使用中出現(xiàn)下沉的的原因還有就是廠家在生產(chǎn)設(shè)計球墨鑄鐵井蓋井體及井周構(gòu)造設(shè)計尺度較低，井周回填及井周路面各構(gòu)造層咩有進行專項補強設(shè)計等。如果在城市交通中有大批重型超載車輛，對下水井及井周形成損壞。

Among them, the reasons for the sinking of ductile cast iron well cover in use are that the design scale of well body and surrounding structure of nodular cast iron well cover in production design is relatively low, and special reinforcement design is carried out for each structural layer of the well surface and backfill around the well. If there are a large number of heavy and overloaded vehicles in urban traffic, it will damage the well and its surroundings.

其次還有可能就是因為在途經(jīng)機動車行道范圍的規(guī)劃布設(shè)管線工程不夠合理?；蛘呔c井周的構(gòu)造，受各自本身自重和車輛荷載作用，必定沉降不一。

Secondly, it is also possible that the planning and layout of pipeline engineering in the range of motor vehicle lanes is not reasonable. Or the structure around the well must have different settlement due to their own weight and vehicle load.

以上就是我們球墨鑄鐵井蓋在使用中出現(xiàn)的下沉原因之一了，不過在井蓋安裝的過程中都有著嚴格的標準，一般情況下不會出現(xiàn)這種情況。如果你想對各項球墨鑄鐵井蓋的小知識進一步的了解，歡迎點擊我們的網(wǎng)站。

The above is our ductile iron well cover in the use of one of the reasons for sinking, but in the process of well cover installation there are strict standards, under normal circumstances, this will not happen.
