U-shaped sheet pile vibration damping and isolation barrier structure
The invention discloses a U-shaped sheet pile vibration damping and isolation barrier structure. The main body structure of the U-shaped sheet pile vibration damping and isolation barrier structure is a U-shaped sheet pile rank which is placed in a soil body between a vibration source and a protection object and is inclined vertically, prefabricated U-shaped steel sheet piles or U-shaped prestressed concrete sheet piles are adopted, the static pressure construction is conducted, and the construction is convenient and rapid; in the static pressure construction process, the U-shaped sheet piles are supported with box iron, the guiding effect is achieved, and pile bodies are prevented from being deviated. A barrier is arranged in the vertical direction in an inclined mode, the barrier can be inclined to the vibration source or can be inclined to the protection object as well, the inclination degree of the U-shaped sheet pile rank needs to be determined according to characteristics of vibration waves, and based on vibration wave characteristic of rail transit and the feasibility of the sheet pile construction, the inclination degree of the U-shaped sheet pile rank preferentially ranges from 1:3 to 1:4. According to the U-shaped sheet pile vibration damping and isolation barrier structure, the phase difference caused by reflection and refraction of the vibration waves on an inclined medium variation belt formed by the sheet pile barrier is utilized, and the vibration waves transmitted to a protected structure are effectively weakened.
