Demand and Process for Manhole Production System

Nowadays, there is a great demand for the manhole production system with the rise in population. In major cities, the subsurface teems with the utilities like sewers, drains, steam tunnels and utility corridors. This has increased the demand for the manhole production system. The manholes are been dug down at regular intervals to allow maintenance with the workers so as they can reach with the subsurface utilities. They are usually covered with the round iron plates that are been sunk into the streets and sidewalks. They are seen on the streets or sidewalks so as it keeps passers-by away from falling into manholes.

Appearance: Manhole can be 56 cm in diameter, can reach maximum up to 60 in diameter. The average weight covered is between 113-136 kg. Following shows with the process of making manhole production.

Pattern: Pattern is been carved out in order to produce with the manhole. They are been designed in the form such that it should be slightly larger than the finished manhole in order to allow shrinkage as the casting tool. Usually, there are two patterns one for the top and other for the lower half that is required for each manhole. The bottom half is flat that is been designed in a three-dimensional spider web.

Mold Preparation: The manhole is been molded into the boxes called as flasks been placed into two halves. There are two flasks, namely upper flask as cope and lower flask as drag. Riser and vents are simply placed into the flask in order to make the molds for the manholes. This is been done with the help of the manhole production system

Melting/Pouring: The scrap steel is been melted at about 2,700°F. It is been collected into a large metal ladle, a riser is been designed to hold the extra molten iron. The oxygen present in the mold gets used up as the organic material burns.

Cooling and Finishing:Complete cooling takes about a day and the molds are been kept for vibration until the sand gets shaken off. Thus a manhole is been produced with the help of the manhole production system.

There are various benefits to the manhole production system that includes cost saving. As compared with the square repairs, round manholes have also been produced with the manhole production system that uses 20% less of the raw material. Also, round manhole allows perfect place and maximum length. Appropriate material and technique with the manhole production system have to be used in order to create a long life as well as making it cost effective. It should result in a way that it can be used for the long-term solution as well as contractor-friendly.

AHCT offers with the effective concrete solutions held with the infrastructure development. We offer with the machine for producing manholes that is nothing but the manhole production system. Other than this system, we offer with the other variety of service that includes pipe making machine,jacking pipe making machine, lined pipe making machine and box culverts. We are the leading manufacturers of cage machinery for manhole production system as well as concrete pipe industries.
