Reinforcing system and method for settlement deformation of tunnel underpass ground building
The invention discloses a reinforcing system and method for settlement deformation of a tunnel underneath passing ground building, and relates to the field of tunnel construction, the reinforcing system comprises a ground building foundation reinforcing structure, and the reinforcing structure is mainly composed of an expanded foundation and a foundation soil body improvement; foundation expansion and foundation soil body improvement are both based on a foundation reinforcement mode of structure optimization, so that a ground building has good settlement deformation resistance and better non-uniform settlement deformation resistance; meanwhile, a grouting system in a newly-built tunnel hole is considered; selective stratum grouting is adopted in the system, the grouting range can be flexibly adjusted according to the situation that shield tunnels of different mileage sections actually penetrate through an upper building, and construction benefits are greatly improved. The construction equipment has the advantages of being light, flexible, convenient to move, easy to operate and the like.
本发明公开了一种隧道下穿地面建筑物沉降变形的加固体系和方法，涉及隧道施工领域，包括地面建筑物基础加固结构，主要由扩大基础和地基土体改良构成；扩大基础和地基土体改良均是基于结构优化的基础加固方式使得地面建筑物具有良好的抗沉降变形性能，且具有更好的抵抗不均匀沉降变形能力；同时考虑了新建隧道洞内注浆系统；该系统采用的是选择性地层注浆，可针对不同里程段盾构隧道实际穿越上部建筑物情况灵活调节注浆范围，大大提升了施工效益。本发明涉及的施工设备具有轻巧灵活、方便移动、容易操作等优点。
