Abstract

Provided is a novel manhole cover assembly. The novel manhole cover assembly comprises a manhole cover and a manhole base, wherein the manhole cover is inlaid into the upper portion of the manhole base. The novel manhole cover assembly is characterized in that two L-shaped clamping grooves which are in central symmetry are formed in the inner edge of the annular manhole base, the top end of each clamping groove is communicated with the upper portion of the manhole base, two protruding handles which correspond to the clamping grooves are arranged on the outer edge of the manhole cover, a lock is installed between the clamping grooves of the manhole base and the protruding handles of the manhole cover, and an unlocking hole of the lock is formed in the manhole base. The novel manhole cover assembly has the advantages that due to the fact that the manhole cover and the manhole base are provided with the lock which can be screwed and be buckled, the manhole cover can be well fixed, and the manhole cover can be effectively prevented from moving and falling off; due to the fact that the manhole cover and the manhole base are mainly made of nonmetal, and do not have economic value, the frequency of the phenomenon that the manhole cover and the manhole base are lost is greatly reduced; due to the fact that pulverized fuel ash materials can serve as the nonmetal of the manhole cover, cost is low, pollution cannot be caused, thermal insulation performance is good, strength is high, heat preservation performance is good, and secondary pollution cannot be caused; due to the fact that a special unlocking tool is arranged, the phenomenon that non-staff members open the novel manhole cover assembly at will is prevented, and use safety of the novel manhole cover assembly is ensured.
