A MANHOLE COVER MADE OF “SPE-SFRC”FOR GUARDING AGAINST THEFT

本文介绍的用SPE SFRC材料制作的窨井盖板 ,生产工艺简单、无污染、成本低 ,经承载力计算及试验证明 ,承载力完全能够满足使用要求 。

A manhole cover made of “SPE\|SFRC” which has simple technolgoy,no air pollution and low cost is presented in this paper.The carrying capacity of this manhole cover proves to be high by the load\|bearing calculation and experiments,therefore,it is a fit alternative of the manhole cover made of cast iron which is often stolen now.
