Abstract

The invention discloses an inorganic high performance thin wall Greek letter pi-shaped structure sheet pile for supporting and protecting a shore. The sheet pile is prepared from an inorganic high performance fiber composite material and prestressed reinforcement by casting. The sheet pile has large bending-resistant moment, a strong soil blocking capacity, a large vertical bearing capacity, light structure weight, small product side wall friction, good product durability and a long life cycle, realizes transverse and longitudinal connection between plates so that a repeating utilization rate is high and is especially suitable for water conservancy and sea shore foundation work support and protection.

Description

technical field [0001] The invention relates to sheet piles used for bank enclosing, support, soil retaining, vertical bearing, etc. in civil engineering such as water conservancy and ocean engineering, and in particular to an inorganic high-performance thin-walled Π structure sheet pile for supporting and maintaining banks. Background technique [0002] The enclosing, supporting and retaining works in water conservancy and coastal civil engineering are the core and main projects, with large engineering volume, difficult construction and many problems. At present, most of them use steel sheet piles, ordinary concrete sheet piles, and prestressed concrete sheet piles. Carry out works such as enclosing, supporting, and retaining soil, and a small part of them use concrete for masonry. The construction is slow, the excavation volume is large, and it is greatly affected by the weather, so it is less and less used. At present, steel sheet piles are used the most, but the main con...
