Abstract
The invention discloses a pressure-reduction and shock-resistant sheet-pile wall structure. The pressure-reduction and shock-resistant sheet-pile wall structure comprises sheet-pile walls each formed by arranging a plurality of sheet piles in a row, elastic bodies and a base plate. The sheet piles are made of fine aggregates, coarse aggregates, cement, ash, anhydrite, micro-silica, diethyl maleate, vinyl chloride, acid clay, magnesium sulfate, polymer adhesives, boron nitride, a water repellent, a polycarboxylic acid water reducer and EVA resin. The number of the sheet-pile walls is at least two, and the sheet-pile walls are arranged symmetrically. The upper portion of each sheet-pile wall is located in the ground surface soil layer and is 0.5-1 m away from the ground surface, and the sheet-pile walls penetrate through the subsoil layer and then are inserted into the substrate. The elastic bodies are arranged on the inner sides of the sheet piles, the upper ends of the elastic bodies are flush with the sheet piles, and the lower ends of the elastic bodies are located in the subsoil layer. The base plate is arranged in the surface layer of the ground surface soil layer, and a building is built on the base plate. Based on the prior art, the elastic bodies are added to absorb shock and reduce pressure, when an earthquake or landslide or debris flow or flood occurs, the soil layer structure is effectively protected, the soil layer pressure is reduced, and the upper-layer building is protected against differential settlement or collapse.
