External connection sinking stopping method and structure for jacking pipe downwards penetrating through water conveying pipe gallery
The invention discloses an external connection sinking stopping method and structure for a top pipe downwards penetrating through a water conveying pipe gallery, and relates to the technical field of comprehensive pipe gallery construction. Micro piles and reinforced concrete brackets are arranged on the outer side of an existing water conveying pipe gallery, so that the existing water conveying pipe gallery is connected with the micro piles through the external connection reinforced concrete brackets; the load of the existing water conveying pipe gallery is transmitted to the micro piles through the reinforced concrete brackets, so that the sinking stopping purpose is achieved. According to the method, the micro piles are externally connected with the reinforced concrete brackets to stop sinking and reinforce, secondary differential settlement cannot occur in a large-settlement area, the existing pipe gallery structure cannot be affected by follow-up pipe jacking construction, and follow-up pipe jacking construction can be conveniently carried out.
本发明公开了一种顶管下穿输水管廊外接止沉方法及结构，涉及综合管廊施工技术领域，在既有输水管廊外侧设置微型桩及钢筋混凝土牛腿，使既有输水管廊通过外接钢筋混凝土牛腿与微型桩相连接，使既有输水管廊荷载通过钢筋混凝土牛腿传至微型桩，以达到止沉目的。本发明采用微型桩外接钢筋混凝土牛腿的方法止沉加固，沉降较大区域不会出现二次不均匀沉降，后续顶管施工对其既有管廊结构不会受到影响，方便开展后续顶管顶进施工。
