Product Description

 

Square and Circular cast ductile iron manhole cover BMC SMC manhole cover

Cast iron manhole covers are generally divided into round and square. In the urban area, circular is generally used, because the round manhole cover is not easy to tilt, which can better protect the safety of pedestrians and vehicles. The use of a circle is mainly due to the fact that the circular manhole cover has the same length through each of its centers, so that if the manhole cover is rolled up by the passing vehicle, the diameter will be slightly smaller than the wellhead below. Wide, the manhole cover will not fall into the wellhead. If square is used, because the diagonal of the square is obviously longer than the length of each side, when the manhole cover is rolled up, it is easy to fall into the well along the diagonal direction of the wellhead. , causing security risks. If the wellhead is rounded or significantly smaller than the manhole cover, the square manhole cover will not fall into the well. This involves the problem of utilization and savings of a material. The use of the wellhead depends on the size of the wellhead. If a square manhole cover with a much larger area than the wellhead is to be installed on it, then the material utilization and practical value are naturally not more effective than using a circular manhole cover directly, which not only saves the material of the manhole cover, but also The safety of the wellhead is ensured and used in the countryside and cable wells, generally square, which can better prevent the entry of liquids such as rainwater.
