Seismic isolation and reinforcement method for existing building foundation
The invention provides a seismic isolation and reinforcement method for an existing building foundation, and belongs to the field of constructional engineering. Reinforcing piles are constructed on the periphery of an existing building; backfill soil located between the existing building and the reinforcing piles is excavated in a segmented mode, meanwhile, reinforcing walls are constructed between the reinforcing piles in a segmented mode, and lateral supporting pieces are constructed between a foundation structure of the existing building and the reinforcing piles; first reinforced concretecast-in-place slabs are constructed between the foundation structure of the existing building and the reinforcing walls by taking lateral supporting pieces, the reinforcing walls and the foundation structure of the existing building as supports; the parts, located below a horizontal lifting beam, of the foundation structure is replaced with a seismic isolation device; and the first reinforced concrete cast-in-place slabs and the lateral supporting pieces are dismantled. According to the method, the foundation structure of the existing building is reliably and temporarily supported through thelateral supporting pieces and the first reinforced concrete cast-in-place slabs, the safety of the existing building structure is ensured when the existing building structure encounters the horizontalearthquake effect in the construction period, and normal and safe use of an upper house in the existing building foundation seismic isolation and reinforcement construction period can be achieved.
本申请提供了一种既有建筑基础隔震加固方法，建筑工程领域。在既有建筑的外围施工加固桩；分段开挖位于既有建筑与加固桩间的回填土，并同时在加固桩间分段施工加固墙，在既有建筑的基础结构与加固桩之间施工侧向支撑件；以侧向支撑件、加固墙和既有建筑的基础结构为支座，在既有建筑的基础结构与加固墙之间施工第一钢筋混凝土现浇板；将基础结构位于水平抬梁以下的部分替换为隔震装置；拆除第一钢筋混凝土现浇板和侧向支撑件。该方法通过侧向支撑件和第一钢筋混凝土现浇板对既有建筑的基础结构形成可靠的临时支撑，确保施工期间遭遇水平地震作用时既有建筑结构的安全性，可实现既有建筑基础隔震加固施工期间上部房屋正常安全使用。
