Anti-corrosion, strong stability, from the river crossed to the sea
U type sheet piles adopt a unique variable cross-section structure design, increase the section height, increase the cross-section resistance to bending moment, but also increase the cross-section width. From the analysis of structural mechanics principle, the stress characteristics and the I-shaped force characteristics are the same, have good bending resistance, and are widely used in inland river. As we all know, sea storms, corrosive seawater is strong, commonly used in offshore engineering embankment pile corrosion resistance is poor, and investment is higher than the precast concrete sheet pile. The design of U type precast concrete piles is taking into account the retaining, corrosion resistance, construction speed and other characteristics, both the characteristics of steel sheet pile, but also to overcome the corrosion of steel sheet pile problem, and stability, and can adapt to more complex Construction condition of sea area. U type sheet pile construction time is short, mechanized construction, significant savings in labor. It changes the traditional construction of water conservancy project, the construction speed is slow, the construction of high labor costs, after forming the quality of instability and other shortcomings, safe, beautiful, reliable and does not require post-maintenance. From the whole project quality, the factory mass production, the quality assurance system can effectively guarantee product quality.
Compared with the traditional method, U type sheet pile has obvious competitive power
In addition, U type sheet pile than the traditional riprap dam greatly saves the cost. Because of the geographical reasons, the stones used in the construction are all from Zhejiang, Jiangsu and other places around Shanghai. With the protection of ecological environment and the promotion of resource saving, Stones and other non-renewable resources to reduce the amount of exploitation, the price of natural rise. With the social development, other costs are also increasing year by year, only a human cost this year than last year increased by 40%, the traditional construction of the dam requires a lot of human resources, greatly increasing the project cost. Although the initial investment is not much difference, but the traditional method of construction cost is much higher than the overall construction cost of U type sheet pile, with the passage of time, gravel resources increasingly scarce, U type sheet pile cost advantage will Unmistakably.
