Archway in-situ protection foundation underpinning structure and construction method
The invention belongs to the technical field of municipal construction, and particularly relates to a memorial archway in-situ protection foundation underpinning structure and a construction method. The construction sequence of underpinning is as follows: protecting the overground part of the memorial archway before construction, constructing side walls of a basement and supporting foundation piles, excavating earth, constructing an underpinning main beam, constructing an underpinning secondary beam to support a foundation bearing platform, connecting the underpinning secondary beam with the underpinning main beam, cutting off the original pile foundation of the memorial archway, and reversely constructing a top plate. According to the foundation passive support changing structure for in-situ protection of the memorial archway and the construction method, support changing of in-situ protection is carried out on the memorial archway under the condition that a building is not dismantled, and underground construction can be conveniently carried out.
本发明属于市政施工技术领域，具体涉及一种对牌坊原位保护基础托换结构和施工方法，托换的施工顺序：施工前对牌坊地上部分保护‑‑施工地下室侧墙和支撑基础桩‑‑土方开挖‑‑施工托换主梁‑‑施工托换次梁将基础承台支撑‑‑托换次梁与托换主梁连接‑‑截除牌坊原有桩基础‑‑逆作施工顶板。本发明提供一种对牌坊原位保护的基础被动换托结构和施工方法，在建筑物不拆除地情况下对牌坊进行原位保护的换托，便于能够在其地下进行施工。
