Double box culverts

I. Marking of AMACCAO sewer pipe concrete is designed with grade 350 to ensure permanent water resistance.

II. Steel core is designed by the Center for Design – Institute of Transportation Technology – Ministry of Transport, designed for the following standards:

1. Roadbed (HB80); Sidewalks (…..), Irrigation (……) and Non-standard (common type).

2. Or the loads: A, B, C, D.

3. All steel used in sewer production is imported steel from abroad.

4. All steel is continuously machined by cold rolling to increase the tensile strength of steel, so it is much higher.

5. The sewer core steel cage is automatically produced in a closed line from cold rolling to cutting, and automatically welded by the Zuplin CNC short welding machine (Federal Republic of Germany), consistently in quality and absolute. steady.

III. Concrete

– Concrete used for sewer casting is produced as Dry Concrete (Extremely Low Humidity) which is produced by the Automatic Concrete Mixing Station system with automatic feeding system and automatic balance adjustment 99.99% accuracy, ensuring 100% concrete mortar batches always exceed the design mark.

IV. Input materials of Concrete:

– Cement for production is 100% cement, imported directly from Nghi Son and Tam Diep factories, with Japanese and Danish technology, is lead-clamped bulk cement for each 60-ton vehicle that is certified by the Factory.

– The stone used for casting AMACCAO concrete pipe is the stone of SAN WAY factory (Lien Khanh with Japan), which is always guaranteed in grain composition, stone grade as well as standard size.

– Viet Tri golden sand 100%.

V. Sewer casting machine: (Italy – Thailand technology)

1. This is Vibration-injection molding machine: This is an automatic drain casting machine, using the technology of both vibrating and pressing with extremely high vibration and pressing frequencies – This is the most modern and most popular technology in developed countries in the world today. Concrete is arranged and pressed tightly, as solid as an artificial “stone block”. The vibrating and pressing process, which has been calculated by experts, does not stratify or partially shove the particulate elements in concrete such as vibrating or centrifugal technologies, which is especially stronger than wet casting technology as popular production in Vietnam today.

2. This sewer molding machine outperforms other machines already in the North, because the use of dry concrete means that large aggregates are allowed, because this advantage allows AMACCAO sewer pipes. Reach a higher level and still only cost the same amount of cement – This is superior.

BECAUSE. Proper maintenance:

– AMACCAO sewer pipes have proper maintenance and special maintenance 2 times over the standard time to ensure that customers use it without being affected when erection.

VII. Regular check-ups

Each batch of “AMACCAO” products is always pressed for testing by 3-dimensional presses: 100% of products pass and exceed, most from 1.2 to 1.5 levels required by Vietnamese standards.

VIII. ISO quality standard

The factory is building an ISO quality control system that is expected to come into operation in December.
