圆形的井盖不易倾斜起到有效安全防护作用

来源:http://www.kpp647.com添加时间:2018-04-10 16:43:04

  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。

  The use of the wellhead depends on the size of the wellhead。 If it is not necessary to install a square well cover which is far larger than the wellhead, the use and practical value of the material will not be more effective, not only to use a circular hole cover directly, not only to save the material of the well cover, but also to ensure the safety of the wellhead。 In the countryside and cable well, the square is generally used, so that we can better prevent the entry of rainwater and other liquids。

  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。

  Generally, it is divided into circular and square. In the road administration of the city, it is usually round, because the circular hole cover is not easy to tilt, and it can better protect the safety of pedestrians and vehicles. The circle is used mainly to take into account that the round hole cover is the same as each of the diameter of the center, so that if the covered vehicle is rolled up, the diameter of the shaft will be slightly wider than the following, and the cover will not fall into the wellhead.

  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 a square is used, because the square diagonal is obviously longer than the length of each side, it is easy to fall into the well along the diagonal direction of the wellhead, causing a safety hazard. If the wellhead is circular or obviously smaller than the manhole cover, the square manhole cover will not fall into the well.
