New and old pipe gallery connecting method capable of reducing differential settlement
The invention relates to the technical field of underground pipe gallery construction, in particular to a new and old pipe gallery connecting method capable of reducing differential settlement. The method comprises the steps that 1, earth excavation is conducted below a bottom plate of a built pipe gallery; 2, reinforcing steel bars of the bottom plate are bound; 3, a bottom plate formwork is installed; 4, bottom plate concrete is poured; 5, side wall reinforcing steel bars are bound; 6, side wall and top plate formworks are installed; 7, top plate reinforcing steel bars are bound; 8, a template is installed at the joint of the top plate; and 9, side wall and top plate concrete are poured. According to the method, a hard connection mode is adopted at the connecting position of a new pipe gallery and an old pipe gallery, the new pipe gallery and the old pipe gallery at the connecting position form a whole, and the purpose of reducing the differential settlement at the connecting position of the new pipe gallery and the old pipe gallery is achieved. Compared with a simple method of arranging a steel-edged water stop belt at the construction joint, the method has the remarkable advantage of reducing the differential settlement.
本发明涉及地下管廊施工技术领域，具体是一种减少不均匀沉降的新旧管廊连接方法；包括步骤1、已建管廊底板下方土方开挖；步骤2、底板钢筋绑扎；步骤3、底板模板安装；步骤4、底板混凝土浇筑；步骤5、侧墙钢筋绑扎；步骤6、侧墙、顶板模板安装；步骤7、顶板钢筋绑扎；步骤8、顶板连接处模板安装；（9）侧墙、顶板混凝土浇筑。本发明通过在新旧管廊连接处采用硬接的方式，将连接处的新旧管廊形成一个整体，以达到减少新旧管廊连接处不均匀沉降的目的。相比于简单的通过在施工缝处设置钢边止水带的方法，在减少不均匀沉降方面具有显著的优点。
