Shock insulation pile foundation structure and construction method thereof
The invention discloses a seismic isolation pile foundation structure and a construction method thereof. The seismic isolation pile foundation structure comprises a seismic isolation bearing platform and a seismic isolation pile foundation. The shock insulation pile foundation is composed of multiple sections of pile foundation units. Each pile foundation unit comprises a restraint layer, a shock insulation layer, an isolation layer and a composite concrete core body; shock insulation supports are arranged between the pile foundation units, and the shock insulation supports are connected with the composite concrete core body through steel bar pin assemblies. In the invention, the restraint layer can improve the compressive strength of the composite concrete core body, the shock insulation layer can effectively absorb the shock energy of the stratum, and the transfer of the shock energy from the pile foundation structure to the upper building main body is obviously weakened. Due to the mutual deformation between the pile foundation units, the shock insulation support has enough tensile and shear rigidity, and has an excellent deformation buffering effect. The pile foundation units and the shock insulation supports improve the structural stability and shock insulation performance of the shock insulation pile foundation, and then the safety and stability of an upper building structure are improved.
本发明公开了一种隔震桩基础结构及其施工方法，其中隔震桩基础结构包括：隔震承台和隔震桩基；隔震桩基由多段桩基单元组成；各桩基单元包括约束层、隔震层、隔离层和复合型混凝土芯体；各桩基单元之间设置有隔震支座，且隔震支座与复合型混凝土芯体通过钢筋销钉组件相连接。在本发明中，约束层能提高复合型混凝土芯体的抗压强度，隔震层能有效吸收地层的震动能量，显著减弱震动能量从桩基础结构向上部建筑主体进行传递。各桩基单元之间的相互变形赋予了隔震支座具备足够的抗拉和抗剪刚度，具有优良的变形缓冲作用。桩基单元和隔震支座提高了隔震桩基的结构稳定性和隔震性能，进而提高上部建筑结构的安全性和稳定性。
