哪些情况下是必须要使用铸铁井盖

来源:http://www.kpp647.com添加时间:2016-11-11 15:28:11

一般情况下,机场、码头快速路等场合属于重载场合,按照国家井盖标谁必须要达到36T以上才能够符合要求,从数据上分析只有球墨铸铁井盖可以达到这个标谁,其它材料井盖的承重能力为:
In general, the airport, dock etc. belong to the heavy-duty expressway, according to the national standard covers who must reach above 36T can meet the requirements from the data analysis only the ductile iron manhole cover can reach the standard of who covers the bearing capacity for other materials:
井盖的承载能力是衡量井盖能否在道路上使用的关键指标,如果承载能力不高,使用时被压坏则与球墨铸铁井盖被盗并无区别。
The bearing capacity of the manhole cover is a key indicator of the manhole cover can be used on the road, if the carrying capacity is not high, the use of crushed and nodular cast iron covers were stolen and no difference.
因此,不论使用何种材质作井盖,在道路上使用,至少要达到《铸铁井盖》标准规定的36t的试验荷载。
Therefore, no matter what the use of material covers, for use on the road, the test load reaching at least to the provisions of the "36t" standard cast iron manhole cover.
随着城市的发展,道路越来越宽,车流量越来越大,载重量越来越高,对井盖的承载能力要求也越来越高。

QQ截图20160902152035.pngWith the development of the city, road widening, traffic is more and more big, the load increasing, the bearing capacity of the manhole cover are increasingly high requirements.
因此,新型材料的井盖不仅要达到现有《铸铁井盖》标准,而且应超过此标准。如果要制定新井盖标准,建议承载能力的划分和规定应参照欧洲标准EN124,机动车道上使用的井盖的承载能力不低于40t。
Therefore, the new material covers not only to achieve the existing "standard" iron covers more than this standard, but also should. If you want to develop new standards and regulations that covers, division of bearing capacity should refer to the European standard EN124, the use of motorized vehicles on the bearing capacity of the manhole cover is not less than 40T.
所以,我们在机场,码头,高速公路等场合,凡有重载经过的必须是球墨铸铁井盖,因为其它材料根本达不到使用要求。
So, we are at the airport, wharf, highway and other occasions, all must be through the heavy ductile iron manhole covers, because other basic materials are not up to the requirements.
它是通过球化和孕育处理得到球状石墨,进而将铸铁的机械功能改善而且进步了很多,它即是球墨铸铁的商品中的一种,十分经用而且很便宜。现在它一般分为圆形和方形,有很强的承受能力,而且还有很强的耐性。
It is through the ball and inoculation treatment to get spherical graphite, which will improve the mechanical function of cast iron and a lot of progress, it is a ductile iron products in a kind of very cheap. Now it is generally divided into circular and square, has a strong ability to bear, but also a strong tolerance.
