The invention discloses a spherical manhole cover cast with nodular cast iron, and belongs to the field of nodular cast iron manhole covers. The spherical manhole cover cast with the nodular cast ironcomprises a manhole cover body; the manhole cover body includes a cover body and a spherical cover surface; the spherical cover surface and the cover body are integrally molded; the longitudinal section of the spherical cover surface is in an arch bridge shape; the outer side of the manhole cover body is sleeved with a manhole cover base; four mounting holes evenly distributed are formed in the top part of the manhole cover base; the inner side of the manhole cover base is provided with manhole cover supporting tables; and the top parts of the manhole cover supporting tables are in contact with the bottom part of the cover body. According to the scheme, by installing the spherical cover surface of which the longitudinal section is in the arch bridge shape, the stereoscopic sense of the surface of the manhole cover body can be effectively enhanced; compared with a planar manhole cover, the spherical manhole cover is more attractive; and after the manhole cover body is designed to be spherical, the spherical manhole cover has bearing capacity higher than the planar manhole cover under the condition of the same weight.
本发明公开了一种球形面球墨铸铁铸造井盖，属于球墨铸铁井盖领域，一种球形面球墨铸铁铸造井盖，包括井盖本体，所述井盖本体包括盖体和球形盖面，所述球形盖面与盖体一体成型，所述球形盖面的纵截面呈拱桥形，所述井盖本体的外侧套设有井盖底座，所述井盖底座顶部开设有四个均匀分布的安装孔，所述井盖底座的内侧设置有井盖支撑台，所述井盖支撑台的顶部与盖体的底部接触。本方案通过纵截面呈拱桥形的球形盖面的设置，可有效的增加井盖本体表面的立体感，相比较平面井盖更加美观，且将井盖本体设置成球面后，相同重量比平面井盖的承载能力更高。
