AI Technical Summary
Traditional polymer composite resin manhole covers lack toughness and are easily damaged, leading to reduced efficiency. Furthermore, their widespread use has resulted in theft of manhole covers, creating urban black holes.
A structure comprising an outer frame, sealing gasket, manhole cover body, telescopic rod, and buffer block was designed, combining a multi-layer structure of wear-resistant layer, anti-corrosion layer, thickened layer, toughness layer, high-strength layer, and resin layer to enhance the toughness and durability of the manhole cover.
It improves the sealing, corrosion resistance and toughness of manhole covers, prevents collapse, extends service life, enhances efficiency, and reduces the risk of theft.
