characteristic:
1. The weight of composite manhole cover is only 1 / 3 of that of iron cover. The installation and operation of the cover are light and flexible.
2. Good self-locking, FRP round manhole cover and well seat unique constraint connection structure, to prevent the car after driving
The self-locking function of manhole cover jumping off the well seat.
3. The tensile strength of FRP is equivalent to that of Q235 steel, and the compressive strength is more than one time higher than that of c30x. The impact resistance, vibration, fatigue and fracture properties of FRP are better than those of steel and iron. The strength safety conditions of the manhole cover used as bearing structure are easier to meet than those of the iron manhole cover.
4. It can be used as well cover to avoid theft of steel manhole cover
The hidden danger of selling waste products can prevent the theft of manhole covers, causing traffic accidents of adults, cars falling into or stuck in wells, and reducing the number of accidents. The owner's economic loss and accident liability.
5. Corrosion resistant, FRP material is naturally corrosion-resistant. It can be used as well cover for acid, alkali, salt, sewage and other corrosive media environment. It has technical and economic competitive advantages.
