Cable tunnel tube is processed by using reinforced concrete pipes, in which our production with the use of a cable bracket, reinforced concrete drain directly processed like a cable tunnel, so it is called the cable tunnel. Cable Tunnel Project is a major initiative grid development, both to make the effect of the face face of the city: the city cobwebs engineering change and beautify the city; and can make the effect of pedestrian traffic safety. The use of conventional cable pulling way, although to some extent, to facilitate people's power, but over many years pulling cables exposed, vulnerable to wind and rain erosion. In recent years, the rapid growth of the load on the one hand the city residents to improve power supply reliability requirements; the other hand, urban planning and construction appearance more and more attention. As urban areas by high voltage overhead lines with pole line corridors and limit the number of loops, and many streets behind the development of social power transmission capacity; the overhead line failure and more, operation mode is not flexible, often causing widespread power outages, seriously affecting the normal life of residents ; overhead lines are generally located on the street side of the green belt of trees to limit growth height; across the street overhead lines and other lines in the power poles private pull Luanche seriously affect the city appearance; due to the various aspects of the live circuit and social impact interference, difficulty of construction of a large city overhead lines and endanger the safety of the broken wire, leakage and other accident-prone. With the rapid development of China's cities, overhead lines exposed many contradictions uncoordinated and urban development. Cable tunnel for cable tunnel project was born, which uses high-tech, through the tunnel of the cable way to change the past, cable pulling way, compared to pulling a cable tunnel cable, more beautiful and safe. With the improvement of people's living standards, in the past only to objects of utility gradually transformed into consideration its aesthetics and safety in a practical basis. Cable tunnel came into being. Cable tunnel tubes appeared in response to application of the tunnel of the cable. Due to reasons of time, the use of the tunnel of the cable using only in some large cities, but with the need to develop, the cable tunnel will be gradually developed into a popular trend, is holding safe, beautiful and practical these three factors, cable tunnel project will be popular in various size cities. Guangzhou Hengsheng Cement Co., Ltd. is a company specializing in large-scale cement component manufacturing industry production, marketing, construction enterprises, the company has a full production qualification, Guangdong producing prefabricated most experienced companies. Corresponding cable tunnel for the call, the Guangzhou Hengsheng actively organize research and development, production out of the tunnel current cable channel pipe into a large body of material supply tunnel construction.
