With the rapid development of the national economy, the overall construction of the city has been driven. The urban area has expanded and the construction of municipal public facilities has developed rapidly. Transportation, electricity, telecommunications, telecommunications, natural gas, water, cable TV, radio and television, chemical, environmental protection, extension of oil pipelines, military, national important security agencies, scientific research bases and other departments of inspection wells, through the manhole cover for routine maintenance, this also Give criminals a chance to take advantage of them. Due to the wide range and large number of manhole covers, it is difficult to supervise. Since the country currently uses ordinary lock-free manhole covers, the crime of directly stealing manhole covers or stealing wires and cables or other public facilities through the manhole cover is becoming more and more rampant. These acts of misappropriation have seriously affected the normal functioning of municipal facilities. The annual stolen cable and cable supports in the country amounted to 550 million yuan, causing great losses to the state and enterprises.
Manhole cover and underground wire and cable anti-theft have become a huge problem that plagues the current municipal construction in China. Shaanxi Hengyun Municipal Road Facilities Co., Ltd., based on the current increasingly serious phenomenon of stealing manhole cover and underground wire and cable, has developed a new type of polymer power cable series locks anti-theft manhole cover, which has complete types, high strength, high degree of polymerization and good toughness. Wear-resisting, corrosion-resistant, weather-resistant, anti-shocking and good weathering resistance, with secondary load-bearing capacity, good impact resistance and tensile strength. Each set of manhole covers is connected to the steering wheel by four or more bolts, and a lock shaft fixed with a lock head and a lock device fixed on the steering wheel, and the manhole cover and the well ring are connected as a whole. Use a special key to open and close. It is simple to open and has excellent anti-theft performance. It is a national patent product. At present, this one is the only one in the country, which has overcome this worldwide problem.
