Multiple functions of composite manhole covers
In the construction process of modern cities, messy line pipes such as electric power systems, fiber optic cables, and water pipelines are introduced from the underground to each household. In the process, problems such as maintenance and repair are unavoidable Many openings will be left on the ground to facilitate future repairs, and the manhole cover is born. And our new earth composite manhole cover is presented on the basis of manhole cover through the best efforts of countless people through professional transformation. The compound manhole cover has the advantages that the previous manhole cover does not have. It can be applied in various places, and has a long service life, high quality, and no repair problems. The function of composite manhole covers is becoming more and more diversified, which makes its development more and more powerful. Composite manhole covers are frequently used in municipal and building construction materials. Most of the composite manhole covers currently on the market have the characteristics of anti-corrosion, high pressure resistance, and large bearing capacity. More importantly, the materials he chose during the manufacturing process are cheap and easy to obtain, and the total manufacturing cost is very low. There is no steel structure, and the entire cover is made of new materials without any value for recycling. This greatly avoids the theft of composite manhole covers. We must know that during the period of using steel cast manhole covers, it is often reported that The manhole cover was stolen. The compound manhole cover has a very strong anti-corrosion ability. Its factory specification is to soak in sulfuric acid for 48 hours, and the quality loss does not exceed 1%. It is conceivable how powerful the anti-corrosion ability is, and people need not worry about lasting The sun and rain will cause damage to the composite manhole cover, which will cause the manhole cover to be brittle and crushed, which may cause accidents. The ability of the composite manhole cover in compression and load bearing is tested by professional software and the new polymer material is selected by high temperature and high pressure forging, which can bear more than 40 tons.
