What is Composite Manhole Cover?

{dede:global.cfg_gsname/} | Updated: 2020-10-28 01:28:26
The fiber reinforced thermosetting composite material based on unsaturated polyester resin, also known as block molding plastic (DMC), is made by pressing forming technology, which is a new type of environmental protection cover plate. The composite manhole cover is made of high temperature and high pressure primary molding technology, which has high polymerization degree and high density, good impact resistance and tensile strength, and has the advantages of wear-resistant, corrosion-resistant, no rust, pollution free and maintenance free.
product characteristics
The mesh reinforcement is used in the composite manhole cover, and the key stress part is specially strengthened. When the inevitable external force impact occurs, the pressure can be dispersed quickly to ensure the safety of the people and vehicles.
Features of composite manhole cover:
High strength: it has high compressive strength, bending resistance and impact resistance, and toughness. After long-term use, the product will not appear the phenomenon of the well cover being crushed and damaged, and the "urban black hole" accident can be completely eliminated.
Appearance beauty: the surface pattern design is exquisite, the color is bright and adjustable, beautifying the urban environment.
No recovery value, natural anti-theft; according to the needs of customers and equipped with locking structure, the property in the well can be prevented from theft.
Strong weather resistance: the manhole cover can be used normally in the environment of - 50 ℃ ~ +150 ℃ through scientific formula, advanced technology and perfect technical equipment.
composite manhole cover
Acid and alkali resistance, corrosion resistance, wear resistance, rolling resistance of vehicles, long service life.
What is compound manhole cover? Installation characteristics of composite manhole cover:
With the continuous development of technology, the manhole cover as a common material for municipal and building has been developed rapidly. The following is a brief introduction to the installation precautions of composite manhole cover:
In order to keep the appearance of the cover beautiful and the surface pattern and handwriting clear, the cover shall be covered with sheet iron or wood during the construction of asphalt pavement, and the black manhole cover can also be painted with waste oil and other brush to prevent asphalt spraying on the manhole cover.
When installing the manhole cover on asphalt pavement, it is necessary to avoid the construction machinery directly rolling the well seat. When the pavement is cast as a whole, a hole slightly larger than the well seat shall be reserved on the road surface and placed after the asphalt is paved.
After the concrete is cast into the well seat or asphalt is laid, the cover shall be opened and cleaned in time to avoid mortar or asphalt pouring the manhole cover and the seat into one, so as to avoid affecting the opening in the future.
