The filling of the manhole tops model GIA must be performed according to certain statements, mainly on the laying sites submitted to sudden temperature changes, or requiring a very stressed utilization of the device. The internal surface of the covers must be free of any
residual that may compromise the setting of the mortar oil, grease, ands ecc), The mortar must be filled at a temperature not lower than 10°C, in the right measure and duly levelled. The same roughness of the pavement must be preserved. The covering of the device with a sheet , for the first 24 hours of aging, is appropriated to avoid a fast hardening. Should the temperature be lower than 10°C, the protection must be kept for the first 48 hours. The aging of the mortar must be performed ac_x005f_x0002_cording to the times and instructions given by the mortar producer

Competitive Advantage:


1. Put damage:

This is the biggest characteristic of ductile iron manhole covers, ductile iron manhole covers can be heavy pressure 36T/60T, light can be confined 21T. Even if the load pressure exceeds its limit, ductile iron manhole cover cast iron manhole cover is not as common as broken, but a slight deformation of the car and pedestrians has a certain security.

2. Anti-shock:

only through the mouth of the Manhole set to U-shaped, with a T-type synthetic rubber, U-shaped slot embedded in the contact Manhole covers and the process in order to cushion and reduce the vibration force.

3. Anti-slip:

3mm tread covers convex surface, and thus play a good non-slip effect.

4. Anti-impact:

Manhole covers the contact with the colossal surface, directly on the T-rubber, and dealt with gently, to eliminate noise.
