At present, the grooved pipe fittings we use are generally made of cast iron, so many people who do not want to pay attention to this point, and the robbery of grooved pipe fittings is increasingly rampant. Then we must come up with a complete set of methods and strategies to prevent the recurrence of the stolen time of grooved pipe fittings. Domestic theft and damage to municipal public facilities occur frequently, especially the manhole cover of cast iron grooved pipe fittings is the most serious. According to the specific technical requirements of heavy traffic and vehicle load, other cities have carried out the research and development of steel fiber cement concrete inspection manhole covers for grooved pipe fittings.
After comparative experiments and technical and economic comparisons, milled steel fibers are finally selected as fiber reinforcement materials for high-strength steel fiber concrete. It is reported that more than 90,000 manhole covers made of steel fiber materials have been installed after the improvement project of the back streets and alleys in Hangzhou in the past few years. Except for occasional damage, none of them have been stolen so far, because steel fibers have no recycling value. Thieves are not interested. Hangzhou City plans to replace the manhole cover of cast iron grooved pipe fittings in the urban area within 3 years. By 2010, thieves will not think about the manhole cover in Hangzhou.
