How to achieve the effect of shockproof and antiskid for compound manhole cover
Shock-proof effect. A sealing strip is set at the end of the well ring to cushion the contact between the manhole cover and the well ring and reduce the vibration force. At the same time, the compound manhole cover is not easy to be damaged, which has a certain safety guarantee for vehicles and pedestrians.
2 the contact occlusal surface between the composite manhole cover and the well ring acts directly on the T-shaped rubber strip, which overcomes the rigidity and eliminates the noise. A square groove protrudes from the outer ring of the manhole cover, and the open ring at the inner wall end of the well cover is connected with the manhole cover through the fixed shaft of the well seat. In addition, the surface of the composite manhole cover adopts 3mm convex pattern, which has good anti-skid effect.
A sealing strip is set at the end of the well ring to play a buffer role and reduce the vibration force during the contact between the well cover and the well ring. The main feature of compound manhole cover is to prevent wear and tear. The compound manhole cover will not break like the ordinary manhole cover, which has certain safety guarantee for vehicles and pedestrians.
3 It is a compound manhole cover surface convex 3mm pattern, so as to play a good anti-skid effect. It avoids the displacement caused by mechanical rolling in the process of road construction, and has a certain anti-theft effect. When the manhole cover is opened and placed 90 degrees, the manhole cover can be removed to facilitate construction.
