Features of cast iron rainwater grate) Anti-sound: The contact and bite surface of the manhole cover and the manhole ring directly acts on the rubber strip to eliminate noise by softly overcoming rigidity. ) Anti-theft: A square groove protrudes from the outer ring of the manhole cover. The split ring at the inner wall end of the manhole cover is connected to the manhole cover through the fixed shaft of the well seat. The other end is fixed with a pin on the inner wall to prevent theft. When the manhole cover is opened and placed, the manhole cover can be removed for convenience. construction. The hidden lock uses a nylon bushing that will never rust and is equipped with a special tool to open safely and reliably. ) Anti-slip: The surface of the manhole cover adopts raised patterns to play a good anti-slip effect. ) Shockproof: By setting a groove at the stop of the well ring and inserting a synthetic rubber strip into the groove, it plays a buffering role to reduce the vibration force during the contact between the manhole cover and the well ring. ) Anti-displacement: Four riveting bolt holes are reserved in the well circle and are evenly distributed. Each set of ground anchor bolts is used to avoid displacement due to mechanical rolling during the road construction process and plays a certain anti-theft role. ) to prevent damage: This is the biggest feature of cast iron rainwater grate. Heavy cast iron rainwater grate can bear pressure/light weight can bear pressure. Even if the load pressure exceeds its limit, the cast iron rainwater grate will not break like ordinary cast iron manhole covers but will deform slightly, which provides a certain safety guarantee for vehicles and pedestrians.
