球墨铸铁井盖的等级划分

来源:http://www.kpp647.com添加时间:2016-08-12 16:04:47

球墨铸铁井盖等级标志设置场合轻型Q 禁止机动车进入的绿地、甬道、自行车道或人行道普通型P 汽10级及其以下车辆通行的道路或停放场地重型Z 机动车通行的道路或停放场地井盖是用来掩盖道路上或家中深井的防御物,用来防止行人或物体坠落。

Nodular cast iron manhole cover grade mark sets the occasion light Q prohibit vehicle into the green, corridor, self lane or ordinary sidewalk type steam P level 10 and the following vehicle road traffic or parking space heavy Z motor vehicle traffic road or parking site covers is used to cover up the matter on the road or in a deep well of defense, to prevent pedestrians or objects falling。

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 divided into circular and square in downtown road, usually circular, because round manhole cover is not easy to incline to better protect the pedestrian and vehicle safety。 Using the circular, mainly considering the circular covers through the center of each diameter length is the same, so if the manhole cover by the passing vehicles rolling, because no matter how to roll, the diameter will be slightly wider than the below the wellhead, the manhole cover will not fall to 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。

And if the square。 Because of the diagonal of the square was significantly longer than that of each of its sides。 Such covers are rolling, easily along the wellhead in the diagonal direction fell into the wells, resulting in potential safety problems。

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。这里就牵涉到一个材料的更大利用和节约的问题。

If the wellhead made into round or significantly less than the cover, will not fall into the well covers square。 Here is the problem of the maximum use and saving of a material。

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。

Wellhead are used depending on the size of wellhead, if you want to install it on top of an area is far greater than the square manhole cover for a wellhead, then the utilization and practical value of the material no natural directly using the circular covers more effective, not only save covers material, but also to ensure the safety of 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.
