圆形和方形球墨铸铁井盖性能区分

来源:http://www.kpp647.com添加时间:2016-11-14 18:25:08

球墨铸铁井盖一般分为圆形和方形,在市区的路政方面,一般采用圆形,因为圆形的井盖不易倾斜,能够较好的保护好行人和车辆的安全。使用圆形,主要是考虑到圆形的井盖通过其圆心的每条直径长度都是一样的,这样如果井盖被经过的车辆轧起时,因为不论如何轧起,其直径都会比下面的井口略宽,井盖不会掉到井口里去。
Ductile iron manhole cover is generally divided into round and square, in the city's highways, usually circular, because the circular manhole cover is not easy to tilt, can better protect the pedestrian and vehicle safety. Use the circular, mainly taking into account the circular covers through its center of each diameter length is the same, so if the covers were passing vehicles rolled up, because no matter how rolling, the diameter will be slightly wider than the wellhead, will not fall to the wellhead to manhole cover.
而如果采用方形,因为方形的对角线明显长于其每条边长,这样的井盖被轧起时,很容易沿井口的对角线方向掉进井中,造成安全隐患。如果井口做成圆形或明显小于井盖,方形的井盖就不会掉进井中。

If the wellhead made into round or significantly less than the cover, will not fall into the well covers square.
这里就牵涉到一个材料的最大利用和节约的问题。井口的使用取决于井口的大小,如果非要在上面安装个面积远远大于井口的方形井盖,那么材料的利用和实用价值自然没有直接使用圆形的井盖更有效,既节约井盖的材料,也保证了井口的安全。而在乡下和电缆井利用的,一般采用方形,这样可以更好地预防雨水等液体的进入。
Here is the problem of the maximum use and saving of a material. The wellhead is used depends on the size of the wellhead, if to a non square manhole cover installed in the above area is far greater than the wellhead, then the material utilization and practical value of nature is not directly using the circular covers more effective, saving material covers also ensures the safety of the wellhead. While in the countryside and the use of cable wells, generally square, so that it can better prevent the rain and other liquids into the.
