井盖上随时有车辆行人经过,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,它直径都会比下面的井口略宽,井盖不会掉到井口里去
Vehicle pedestrians pass through the covers at any time. The use of circular covers mainly takes into account that the length of each diameter of the covers passing through the center of the covers is the same, so that if the covers are rolled up by passing vehicles, because no matter how rolled up, the diameter of the covers will be slightly wider than that of the wellhead below, and the covers will not fall into the wellhead.
如果采用方形,因为方形的对角线明显长于其它每条边长,边长与对角线之比为一比根号二。这是因为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。
If the square is used, because the diagonal line of the square is obviously longer than the other side lengths, the ratio of the side length to the diagonal line is one root number two. This is because when the cover is rolled up, it is easy to fall into the well along the diagonal direction of the wellhead.
这里就牵涉到一个材料的利用和节约的问题。井口的使用取决于井口的大小,如果非要在上面按个面积远远大于井口的方形井盖。
Here is a matter of maximizing the use and saving of materials. The use of the wellhead depends on the size of the wellhead, if it is not necessary to press a square cover on it which is much larger than the wellhead.
