Reinforcing structure and method for shield tunnel underneath passing existing building group
The invention relates to a tunnel construction reinforcing technology, and particularly discloses a reinforcing structure and method for a shield tunnel underneath passing existing building group, the reinforcing structure comprises a building reinforcing foundation and a tunnel reinforcing body, the building reinforcing foundation is located on the lower portion of a foundation of a ground building and used for supporting and reinforcing the ground building, and the tunnel reinforcing body is located on the upper portion of the tunnel. The building reinforcement foundation comprises an enlarged foundation precast slab and anchoring bodies symmetrically arranged on the two sides of the enlarged foundation precast slab, a pouring pipe is arranged in the enlarged foundation precast slab, and a grouting branch pipe penetrating into a soil layer around the enlarged foundation precast slab is further arranged outside a pipe body of the pouring pipe; a containing groove is formed in the top of the expanded foundation prefabricated slab, a supporting body matched with the containing groove is arranged in the containing groove, any anchoring body comprises a vertically-arranged pipeline and a steel-concrete structure body arranged on the periphery of the pouring pipeline, and the bottom end of the pipeline communicates with a pouring pipe in the expanded foundation prefabricated slab. The method has the advantages of being good in reinforcing effect and effective in reinforcing measure.
本发明涉及隧道施工加固技术，具体公开了一种盾构隧道下穿既有建筑群的加固结构及方法，包括建筑加固基础和隧道加固体，建筑加固基础位于地面建筑物的地基下部、并用于支撑加固地面建筑物，隧道加固体位于隧道上部，其特征在于，建筑加固基础包括：扩大基础预制板，对称设于扩大基础预制板两侧的锚固体，在扩大基础预制板的内部设有浇筑管，浇筑管的管身外部还设有刺入至在扩大基础预制板四周土层中的注浆支管；扩大基础预制板的顶部开设有容纳槽，在容纳槽内设有与其相适配的支撑体，任一锚固体包括竖直设置的管道和设于浇筑管道四周的钢混结构体，管道底端与扩大基础预制板内部的浇筑管相连通。本发明具有加固效果好，加固措施有效的效果。
