brief introduction

The materials used for manhole covers were mostly reinforced concrete, but due to their high brittleness, susceptibility to aging, and fracture, they were gradually replaced by cast iron and ductile iron materials. A new type of high-strength composite magnesite manhole cover has emerged. Compared with traditional cast iron and cement well covers, magnesite well covers have low cost, beautiful and durable appearance, high strength, low noise, and no recycling value. They are good replacement products for traditional well covers.

Magnesia manhole cover is a new type of manhole cover made by using modified magnesite cement as the binder, adding a large amount of organic or inorganic fillers, and reinforcing with glass fiber and bamboo reinforcement. It has been successfully applied in Shandong, Jiangsu, Henan and other places, achieving good social and economic benefits.

characteristic

1. High strength: Magnesium inspection has high compressive, bending, and impact resistance, as well as toughness. After long-term use, this product will not cause the manhole cover to be crushed or damaged, and can completely prevent the occurrence of "urban black hole" accidents.

2. Appearance beauty: The surface pattern design of the magnesite inspection manhole cover is exquisite, with bright and adjustable colors, beautifying the urban environment.

3. Easy to use and lightweight: The product weighs only about one-third of cast iron, making it easy to transport, install, and repair, greatly reducing labor intensity.

4. Anti theft: Magnesium inspection manhole covers have no recycling value and naturally prevent theft; According to customer needs and equipped with a locking structure, it can prevent theft of property inside the well.

5. Strong weather resistance: The magnesite inspection manhole cover can be used normally in environments ranging from -50 ℃ to+300 ℃ through scientific formulas, processes, and advanced technical equipment.

6. Acid and alkali resistance, corrosion resistance, wear resistance, vehicle crushing resistance, long service life.

purpose

Inspection wells and manhole covers are required for places where public facilities such as tap water, limited television, drainage, telecommunications, mobile, China Unicom, electricity, gas, heat, fire protection, and sanitation are installed.
