The utility model discloses a gas proof, ventilation, heating, drainage, fire fighting, electric power and other special luminous anti-theft manhole covers. The manhole cover is composed of a cover body and a manhole cover seat, a cover body structure is divided into two layers. The upper layer is the luminescent layer composed of glass beads and light storage material, the lower base, by Magnesium Oxide, is magnesium chloride, glass fiber, bamboo, modifier M4 and steel fiber reinforced material mixed by die most pressing, set the anti-theft alarm device or gas leakage alarm device on the cover and manhole cover seat. Because the upper cover of the well cover is provided with a light storing material and a glass bead, the cover can be automatically reflected at night, and the position of the well cover is displayed. The lower layer of the well cover is made of inorganic materials, and the cost is low, and the strength of the manhole cover is higher than that of the steel fiber and the glass fiber. An alarm device is arranged between the cover body and the well cover seat, which has the function of theft prevention and gas leakage prevention.
