How to prevent the deformation of the ductile iron rainwater

Botou tianlong casting ductile iron rainwater is made of ductile iron, generally not deformed, especially with good quality, can be maintained for a long time. However, as time increases, there will be slight deformation problems in feng shui. We can delay the deformation time and deformation strength by the following methods. How to prevent the deformation of ductile iron rainwater, there are usually three kinds of prevention methods.

1. When the groove is narrower, it can be used in artificial or frog ramming machine. Different packing, different packing thickness should be used to use different tamper pressing equipment to achieve economic compaction.

2. guess the mud filling and roots, the grass and rotting plants which impact compaction, and dry shrinkage, decadent holes in soil, these data are not as filler, avoid lead to settlement.

3. The control of the aggregate water content of cast iron well cover is greater than that of the better moisture content. It is necessary to first drain the water and then fill it with compaction.

Botou tianlong casting can test and test the above methods in practice, and also improve the safety and safety of rain-cast iron manhole covers.
