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 decompression and earthquake-resistant sheet pile wall structure, comprising a sheet pile wall composed of a plurality of sheet piles arranged in a row, an elastic body and a base plate; the sheet piles are composed of fine aggregate and coarse aggregate. , cement, ash, anhydrite, silica fume, diethyl maleate, vinyl chloride, acid clay, magnesium sulfate, polymer binder, boron nitride, water repellent, polycarboxylate water reducer, EVA resin; there are at least two symmetrically arranged sheet pile walls, and part of the sheet pile wall is 0.5-1m away from the surface plane in the surface soil layer, passes through the core soil layer, and is inserted into the subsoil layer, and the elastic body is arranged on the surface of the sheet pile. The inner side, the upper end is flush with the sheet pile, the lower end is in the core soil layer, the base plate is set in the surface layer of the surface soil layer, and the building is built on the base plate. The invention adds an elastic body on the basis of the prior art, which can absorb shock and reduce pressure, effectively protect the soil layer structure, reduce the soil layer pressure, and protect the uneven settlement of the superstructure when earthquakes, landslides, debris flows or floods occur. 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 ...
