Stainless steel invisible manhole cover is used to cover the defense on the road or in the deep well in the home to prevent people or objects from falling.
Manhole covers are generally divided into circular and square. In urban areas, the circular covers are generally used because circular manhole covers are not easy to tilt and can better protect the safety of pedestrians and vehicles. The use of circular is mainly considered that the diameter of the circular manhole cover through the center of each circle is the same, so if the manhole cover is rolled up by the passing vehicle, because the diameter will be slightly larger than the wellhead below, Wide, the manhole cover will not fall into the wellhead.
If the stainless steel invisible manhole cover is square, the diagonal of the square is obviously longer than each side. When this stainless steel invisible manhole cover is rolled up, it is easy to fall into the well along the diagonal direction of the wellhead, posing a safety hazard. If the wellhead is made round or significantly smaller than the manhole cover, the square manhole cover will not fall into the well. This involves a question of the use and conservation of materials. The use of a wellhead depends on the size of the wellhead. If it is necessary to press a square well cover with an area much larger than the wellhead, the use and practical value of the material is naturally more effective than using a round well cover directly, which saves the material of the well cover and also Ensure the safety of the wellhead.
