球墨铸铁井盖的分类和优点!

来源:http://www.kpp647.com添加时间:2020-05-27 11:20:36

  井盖有多种类型,包括单层、双层、铸铁井盖、球墨铸铁井盖、复合井盖、水泥混凝土井盖等。其中球墨铸铁井盖使用更为广泛。

  There are many types of well covers, including single-layer, double-layer, cast iron well covers, ductile iron well covers, composite well covers, cement concrete well covers, etc。 Among them, nodular cast iron manhole covers are most widely used。

  常用球墨铸铁井盖等级标志设置场合:

  Setting occasions of common ductile iron manhole cover grade mark:

  类型一:(至少选择A15型):绿化带、人行道和其他区域,防止灵活车辆进入。

  Type I: (at least type A15): greenbelt, sidewalk and other areas to prevent flexible vehicles from entering.

  类型二:(至少选择B125型):人行道、非机动车、停车场和地下停车场

  Type II: (at least type B125): sidewalk, non motor vehicle, parking lot and underground parking lot

  场地。

  Site.

  第三类:(至少选择C250型):住宅区北街、冷巷、仅由轻型车辆或小型汽车行驶的区域,通过两侧0。5m范围内的路缘石。

  The third type: (at least C250 type): Residential Area North Street, cold lane, area only driven by light vehicles or small cars, passing through the curbs within 0.5m on both sides.

  第四类:(至少选择D400型):城市主干道、高速公路、高速公路等区域。

  The fourth category: (at least D400 type): urban trunk roads, expressways, expressways and other areas。

  井盖通常分为圆形和方形。在城市高速公路中,通常使用圆盖,因为圆盖不容易倾斜,并且能够更好地保护行人和车辆的安全。

  Well covers are usually divided into round and square. In urban expressway, the round cover is usually used, because it is not easy to tilt, and can better protect the safety of pedestrians and vehicles.

  使用圆形球墨铸铁井盖的优点

  Advantages of using round ductile iron manhole cover

  圆形球墨铸铁井盖的使用主要是基于每个圆形井盖穿过其的直径长度是相同的,所以如果井盖被过往车辆卷起,其直径会比下面的井口略宽,井盖不会落入井口。但是,如果采用正方形,由于正方形的对角线明显大于两边的长度,这样的井盖卷起时,很容易沿着井口的对角线落入井内,造成安全隐患。

  The use of round nodular cast iron manhole covers is mainly based on the same diameter and length of each round manhole cover passing through its center, so if the manhole cover is rolled up by passing vehicles, its diameter will be slightly wider than the hole below, and the manhole cover will not fall into the wellhead. However, if the square is adopted, the diagonal of the square is obviously longer than the length of both sides, so when the well cover is rolled up, it is easy to fall into the well along the diagonal of the wellhead, causing potential safety hazards.

  如果井口是圆形的或明显小于人孔盖,方形人孔盖不会落入井中。这涉及到较大限度地利用和节约材料的问题。井口的使用取决于井口的大小。如果需要安装面积比井口大得多的方形井盖,材料的利用和实用价值自然不会比直接使用圆形井盖更有效,这样不仅节省了井盖的材料,而且保证了井口的安全。然而,在农村地区和电缆井,广场通常被使用,这可以更好地防止液体,如雨水进入。

  If the wellhead is round or obviously smaller than the manhole cover, the square manhole cover will not fall into the well. This involves the problem of using and saving materials to a large extent. The use of the wellhead depends on the size of the wellhead. If it is necessary to install a square well cover with a much larger area than the wellhead, the utilization and practical value of the material will not be more effective than the direct use of the round well cover, which not only saves the material of the well cover, but also ensures the safety of the wellhead. However, in rural areas and cable wells, squares are often used, which can better prevent liquid, such as rainwater, from entering.
