Junked tire vibration damping and isolating building foundation and construction method thereof

Abstract

The invention discloses a junked tire vibration damping and isolating building foundation and a construction method thereof. The junked tire vibration damping and isolating building foundation is composed of junked tires, a junked tire composite pile foundation, a junked tire composite strip foundation, a junked tire composite raft foundation and a floor. After recycled and processed simply, the junked tires are arranged in a crisscross mode in sequence according to the sequence of the composite pile foundation below building pillars, the composite strip foundation below walls and the composite raft foundation below the floor, and the inner portions of the tires of all layers and the clearances are filled with earth and the earth is tamped. When shaking occurs, earthquake waves are reflected in the inner portions of the tires and among the tires, and energy is scattered and consumed. The elastic deformation of the tires and the friction slippage function among the internal stuffing consume most energy of the earthquake waves. Additional confining pressure generated by lateral restraint of tires under vertical pressure enables the intensity of the foundation to be improved obviously. According to the construction method, the junked tires are utilized, waste resources are recycled, black pollution is relieved, the vibration damping and isolating effects are good, the construction procedures are simple, and the application range is wide, and the construction method has remarkable economic, social and environmental protection effects.

Description

technical field [0001] The invention belongs to the technical field of building vibration reduction and isolation foundations, and in particular relates to a waste tire vibration reduction and vibration isolation building foundation and a construction method thereof. Background technique [0002] The essential function of the foundation vibration reduction and isolation technology is to separate the structure or component from the seismic ground motion that may cause damage by increasing the flexibility of the system and providing appropriate damping. Because of its easy implementation, good vibration control effect, and significant advantages in disaster prevention and mitigation as well as social and economic benefits, it has been successfully applied in the fields of building structures and bridge engineering in recent decades. The existing building foundation vibration reduction and isolation systems mainly include laminated rubber pad vibration isolation system, slidi...
