Prestressed pipe is primarily to ensure the stability of prefabricated members. The key technology of prestressed pipe can greatly improve the reliability and quality coefficient of the prefabricated components. The main factor causing this situation is that the technical application of prestressed pipeline can continuously strengthen the tensile capacity of each component, and effectively avoid the construction cracks caused by highway and bridge in the process of engineering construction. Even if building cracks have occurred during construction, the tensile strength of different butt fasteners can reduce the damage of concrete.

In addition, in the concrete project to increase the corresponding prestressed pipe, can reduce the load of the concrete project, after reducing the load, the concrete gap may slowly recover. It can continuously strengthen the fatigue relief of prefabricated components in road bridge engineering construction, and make full use of their own characteristics, the stability and reliability of highway bridge. Secondly, it can adjust the net weight of highway Bridges. In highway bridge engineering construction, the key technology of prestressed pipeline can not only ensure the stability of prefabricated components, but also reasonably adjust the self-weight of highway bridge. In highway bridge engineering construction, the key technology of prestressed pipeline needs high quality raw materials as the auxiliary technology. Therefore, in highway bridge engineering construction, concrete viscosity is strong, construction pipeline compressive strength is strong. This can not only ensure the construction quality, reduce the application of a large number of raw materials, but also reduce the net weight of the highway bridge itself, flexible use of construction pipeline raw materials.

If we analyze the application of prestressed pipeline technology from the perspective of economic development, then the technology of prestressed pipeline can reduce the engineering construction cost of engineering construction units, and create a lot of economic benefits for engineering construction units. It can be seen that the key technology of prestressed pipeline in highway bridge engineering construction, whether the highway bridge itself or the construction unit, has a great effect.
