Excellent performance and low price. Compared with other concrete piles, U-shaped plate pile while maintaining the same width, the consumption of materials is relatively small. For example, under the condition of large-scale use of prefabricated reinforced concrete piles, U-shaped steel piles more material, while the use of prestressed concrete structure, U-shaped steel sheet pile structure has obvious advantages. In addition, U-shaped piles after the completion of the design, according to the design requirements and production orders for reasonable adjustment and installation, with a wide range of geological applications. According to geological conditions and static pressure, and then easy to control the formation of pile construction quality, to ensure that the U-shaped pile combination and shape symmetry.
Good mechanical performance. U-shaped plate pile and other cross-section piles under the same cross-sectional conditions, U-shaped steel plate inertia relative to ordinary rectangular steel sheet pile bending moment greatly increased, so the improvement of bending shear performance, with relatively excellent mechanical properties. At the same time, because the ordinary sheet pile can not meet the larger mud height required space, will be around the high voltage wire or other facilities location restrictions, piling will be difficult to achieve, easy to cause structural damage.
The construction technology of water dike is low. U-type sheet pile in the construction of the various stages of the engineering design and construction requirements are not high, if the process control is not good or does not meet the construction requirements, easy to cause damage to the pile. However, due to the U-shaped piles of prestressed pipe piles, the dam construction process requirements are relatively low, easy to build and implement.
