The cover plate is a well plate made of steel grating. There are a variety of models to choose from to suit different span loads and requirements. It is widely used in different places such as road construction, garden facilities, residential quarters, schools, sports stadiums, etc. According to the different use occasions, the surface of different specifications and models of ditch well boards can be hot-dip galvanized, cold galvanized (electroplating) or untreated.
Among them, the most widely used is the composite cable trench cover, which is based on cement, supplemented by orthopedics, glass fiber, minerals, modifiers, etc. In order to make up for the insufficient application of some products, it has the characteristics of light weight, high strength, long service life, and easy operation and construction. This material is certified and recommended for use in railway ancillary construction. After years of accumulation, the auxiliary structures made of this material have been successfully used in passenger dedicated lines and urban transportation projects.
Having a certain strength and load-bearing capacity is the basic requirement of the cover plate. We can choose different materials according to the application. Obviously, the carrying capacity of 2 wooden well plates and plastic well plates cannot meet the requirements of cable well plates. In the past, traditional well plates were dominated by stone well plates or metal well plates, but now there is a glass fiber reinforced plastic well plate that is not inferior to the two.
The safe performance of the cover plate is mainly reflected in the aspects of heat conduction, electrical conductivity, and toughness. Stone well plates do not conduct heat or conduct electricity, but they do not have a certain degree of toughness, and are as easily damaged or deformed as metal well plates. The thermal conductivity of the power well plate is very strong, and the electrical conductivity is all the properties of metal. In terms of stability, only the glass fiber reinforced plastic trench cover can fully meet the specified requirements, is not thermally conductive, and has strong toughness.
