今天在这里就由小编来为大家介绍一下有关复合井盖的优点性能的一些相关信息，希望可以帮助大家在以后购买使用的时候可以有所用到，请大家跟随小编一起来了解一下以下内容介绍吧：

钢纤维混凝土复合井盖是原钢筋混凝土检查井盖的改良产品。它是在混凝土中加入长约2厘米左右的钢纤维，大量的钢纤维分散在混凝土中。而形成不规则的放射状分布。从而使混凝土强度得到加强。大大提高了混凝土的韧性。其抗弯拉强度、抗疲劳开裂强度等都得到了很大的提高， 同时可以减小裂缝宽度。

为了减少钢纤维混凝土复合井盖在使用过程中崩边现象，一般在复合井盖外边加金属框。钢纤维混凝土复合井盖的强度要比同配比下的普通混凝土复合井盖提高了30%以上，各项性能接近了铸铁复合井盖。

Xiaobian here today to tell you about the advantages related to the performance of composite covers some of the relevant information, I hope to help everyone in the future use when you can buy some used, please follow Xiaobian a look at the following description it:

Steel fiber reinforced concrete composite covers the original reinforced concrete manhole covers of improved products. It is adding about 2 centimeters of steel fibers in concrete, a lot of steel fibers dispersed in the concrete. And an irregular radial distribution. So that the strength of concrete has been strengthened. Greatly improving the toughness of concrete. Flexural tensile strength, fatigue strength and so get cracking greatly improved, while reducing the crack width.

In order to reduce steel fiber reinforced concrete composite covers chipping phenomenon in the course of the general increase in composite covers the outside of the metal frame. Strength of steel fiber concrete composite covers the same proportion than under ordinary concrete composite covers improved by more than 30%, the performance close to the iron composite covers.
