Description

Technical Field

[0001] The present application relates to the technical field of plastic-steel sheet piles, and in particular to a novel enhanced plastic-steel sheet pile. Background Art

[0002] In the field of foundation construction, sheet pile structures are widely used, and they often play the role of retaining soil and resisting seepage. According to the different materials of sheet pile structures, they can often be divided into wooden sheet piles, steel sheet piles and concrete sheet piles. According to different settings, they can usually be set as flat sheet piles, bent sheet piles, concave and convex sheet piles, etc. Due to the nature of their materials, wooden sheet piles are easily corroded by insects. Concrete sheet piles are not conducive to transportation and construction due to their large self-weight, and have poor operability; therefore, in actual construction, steel sheet piles are more widely used. Plastic steel sheet piles are a new type of water conservancy building material, commonly used in river bank protection, waterway bank protection, sluice anti-seepage and other projects. The material itself is a high molecular resin polymer, which is non-corrosive and pollution-free, providing an economical and environmentally more optimized option for water environment management. When constructing plastic steel sheet piles, they are often sent into the corresponding stratum with the help of pile delivery equipment, and the adjacent two sheet pile structures match each other to form a continuous "wall" structure, which separates the accumulated water and silt on one side of the sheet pile structure, thereby meeting the construction of facilities and projects on the other side.

[0003] After searching, the Chinese patent with application number: 202221793238.0 discloses a flood-proof ecological sheet pile, including a sheet pile body, a C-shaped locking part and a T-shaped locking part are respectively arranged on both sides of the sheet pile body, adjacent sheet pile bodies are connected by the C-shaped locking part and the T-shaped locking part, and a sealing strip is also arranged between the C-shaped locking part and the T-shaped locking part. The sealing strip is fixed on the C-shaped locking part or the T-shaped locking part, and the sealing strip is arranged along the length direction of the C-shaped locking part or the T-shaped locking part.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following technical defects that need to be improved:

[0005] Since the main body of the plastic-steel sheet pile is still a plate-like structure, in special circumstances, the plastic-steel sheet pile is required to withstand a larger extrusion pressure. However, the tensile strength and bending strength of common plastic-steel sheet piles are insufficient. As the use time increases, they are easily squeezed and deformed, and their service life needs to be improved. Utility Model Content
