Comparative Analysis of Mechanical Properties of the Self-adjustable Lifting Manhole Cover and the Rraditional One
摘要
Abstract
Based on finite element analysis,considering three working conditions:1) single wheel in the middle of the manhole cover,2) single wheel at the junction of the manhole cover and the road,3) single wheel x meters distance from the junction of the manhole cover and the road,it carried out the comparisons and analysis of stress and deformation of the new type self-adjustable lifting manhole cover and the traditional manhole cover on asphalt concrete pavement.The result showed that the vertical deformation and the wheel stress of the new type manhole cover are less than the traditional one in the three working conditions,and the new type manhole cover can be better compatibly deformed than the traditional manhole cover,reducing the relative destruction of the manhole cover and the surrounding road.The research results of this paper provides theory basis for the popularization and application of the self-adjustable lifting manhole cover.关键词
