The cast iron composite manhole frame & manhole cover is suitable for concrete pavement, which prevents noise, vibration, displacement, accidental opening or closing.
As the entrance of urban underground pipe network, the cast iron combined manhole frame & manhole cover is part of the management details of urban underground pipe network in urban construction.With a high professional quality and sense of responsibility, city builders and managers rely on the visual identification of manhole cover to form a city's symbol and attitude towards the management of underground pipe network.
With the increasing growth and economic development of traffic load and heavy load vehicles, ordinary manhole covers can no longer adapt to the development of roads. Due to the different material between the road surface and the manhole cover frame, and the connection between the manhole cover and the road surface is relatively weak, resulting in the sinking problem of the manhole cover. Unlike traditional manhole covers, this manhole cover extends directly into the well hole, which can solve the problem of the manhole cover under the vehicle rolling. At the same time, the manhole cover is equipped with adhesive tape in the middle, which can play a role in earthquake prevention.
