The reinforcement scheme of nodular cast iron well cover is safer

Bo tou tianlong casting ductile iron manhole cover is an important facility in the road, and the quality of ductile iron manhole cover directly determines whether the pedestrian will have an accident when the road passes. If the iron man hole cover quality is bad will inevitably lead to hidden in our life travel security, to ensure the safety and quality of pedestrian, you should how to circle the spherical cast iron manhole cover?

Ductile iron manhole cover

According to the design requirements of the reinforcing ring, determine the height of the well field. Before installing the steel bone, thoroughly clean the foundation pit and concrete the concrete pouring around the ductile iron manhole cover. The steel skeleton needs to be machined into a square, and the installation meets the wellhead position to ensure that the reinforcement is in good condition.

It is necessary to install the shaft reinforcement and ductile iron manhole cover before the construction of asphalt pavement, and determine the shape and size of the wellbore reinforcement according to the design requirements of the hole cover size and reinforcing well circle. It is usually a square in the center of the well, and the cutting machine is used to cut the pavement structure inside the well.

The embedded bolts can be installed simultaneously with the derrick, and the mold positioning can also be used. The bolt should be placed vertically, and the nut should be tightened before pouring concrete, so that it can be effectively connected with the concrete and the well frame.

In the design of nodular cast iron manhole cover, increase anti-theft device, anti-theft bolt, anti-theft bolt, shaft seat, etc., and open the well cover, do not take out from the shaft, greatly reduce the loss. The ductile iron manhole cover is separated and easy to leave. Therefore, nodular cast iron manhole cover is often lost.

In the case of reinforced ductile iron manhole cover, botoutianlongcasting makes different reinforcement schemes according to different design principles, so this is not random reinforcement, it is cultural, so as to better ensure safety.
