Pile-beam underpinning reinforcement method for non-reserved close-range shield undercrossing railway station building
The invention discloses a pile-beam underpinning reinforcing method for a non-reserved close-range shield under-crossing railway station building. The method comprises the following steps that S1, pile testing is conducted outside a reinforcing pile foundation of a shield under-crossing platform; s2, newly building a pile foundation and a bearing platform outside the original pile foundation needing to be reinforced; s3, steel bars are planted at the junctions of the original frame columns and the prestressed beams; and S4, pre-stressed beams are newly built on the pile foundations and the bearing platforms, and a pile beam underpinning reinforcing system is constructed. According to the pile-beam underpinning reinforcing method for the non-reserved close-distance shield underneath passing railway station building, pile-beam underpinning is adopted for reinforcing, settlement of an existing foundation of the station building in the construction process is effectively reduced, too large disturbance cannot be generated on an adjacent structure, the operation safety is highest, and the pile-beam underpinning reinforcing method has the advantages of being high in construction speed, high in reinforcing efficiency, small in interference on the periphery, low in construction cost and high in practicability. And safe and civilized construction control is good.
本发明公开了一种无预留近距离盾构下穿铁路站房桩梁托换加固方法，包括一下步骤：S1、在盾构下穿站台加固桩基外进行试桩；S2、在需要加固的原桩基外新建桩基及承台；S3、原框架柱与预应力梁交界处进行植筋；S4、在桩基与承台上新建预应力梁，构建桩梁托换加固系统。本发明的无预留近距离盾构下穿铁路站房桩梁托换加固方法，采用桩梁托换进行加固，有效减小了施工过程中站房既有基础的沉降，不会对邻近结构产生太大扰动，运营安全最高，具有施工速度快，加固效率高，对周边干扰较小，施工成本低，安全文明施工控制较好等优点。
