Problems solved by technology

Although the installation cost of wood is very low, if the ground is too hard, it is easy to rot and difficult to install
On the other hand, the initial cost of concrete is high and the construction period is long, so it is not a good choice
Steel structures can corrode due to exposure to water and soil, causing premature deterioration
Due to the low durability of traditional building materials in harsh environments, the maintenance cost of the retaining wall has increased. For this reason, we provide a prefabricated fiberglass corrugated sandwich sheet pile and its assembly method

Abstract

The invention discloses a prefabricated glass fiber reinforced plastic corrugated sandwich sheet pile and an assembling mode thereof, and relates to the technical field of dam retaining walls, in particular to the prefabricated glass fiber reinforced plastic corrugated sandwich sheet pile and the assembling mode thereof, the prefabricated glass fiber reinforced plastic corrugated sandwich sheet pile comprises a connecting circular pile and hollow corrugated sheet piles located on the two sides of the connecting circular pile, and a supporting framework is integrally arranged in each hollow corrugated sheet pile; two symmetrically-distributed limiting notches are formed in one end of the hollow corrugated sheet pile, and a limiting insertion block is integrally arranged at the other end of the hollow corrugated sheet pile. Compared with a traditional retaining wall, glass fiber reinforced plastic is light in weight, high in strength, resistant to corrosion and environmentally friendly from the material angle; from the aspect of structure, the corrugated structure is high in bending resistance, and the defects of a glass fiber reinforced plastic material are overcome; the prefabricated plate pile is suitable for existing low-grade lifting defense, the surface of the low-grade lifting defense is basically not hardened, the plate pile can be directly pressed into soil in a static pressure mode, and large-area excavation is avoided.

Description

technical field [0001] The invention relates to the technical field of dam retaining walls, in particular to a prefabricated fiberglass corrugated sandwich sheet pile and an assembly method thereof. Background technique [0002] In recent years, catastrophic floods have occurred in the Yangtze River Basin in my country many times, and catastrophic floods have occurred in some tributaries or areas, making flood disasters more serious. This structure is mainly used in the reinforcement of existing low-grade dikes to prevent flooding and shore collapse. The construction materials of traditional water retaining structures are wood, concrete and steel, and are usually designed for a service life of 30 years. Although the installation cost of wood is very low, if the ground is too hard, it is easy to rot and difficult to install. On the other hand, the initial cost of concrete is high and the construction period is long, so it is not a good choice. Steel structures can corrode ...
