Problems solved by technology

[0004] However, the existing sheet pile wall does not have the ability to resist earthquakes, and it is easy to bend, deform or even be damaged when it is under pressure. Therefore, it is necessary to design a new type of sheet pile wall with good anti-seismic effect.

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.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a decompression and anti-seismic sheet pile wall structure. Background technique [0002] Sheet pile is a kind of protective pile, which is long and flat in shape, and can be used for protection of low slopes, foundation pits, etc. Reinforced concrete sheet piles are commonly used as a type of pile for the support structure of row pile walls. They have the characteristics of simple construction and short on-site operation period, and are widely used in foundation pits. Its cross-sectional shape and reinforcement are more reasonable for the force on the sheet pile and can be designed according to the needs. At present, sheet piles with a large thickness (such as a thickness of more than 500mm) can be manufactured, and there are hydraulic static pile sinking equipment, so the foundation pit In engineering, it is still a form of use to support the wall. [0003] Sheet ...
