Shallow-buried backfill soil area shield short-distance side penetrating bridge pile foundation construction method
The invention particularly discloses a shallow-buried backfill soil area shield short-distance side penetrating bridge pile foundation construction method. The method comprises the following steps that 1, isolation piles are constructed between a bridge pile foundation and a tunnel structure; 2, top beams are constructed on the tops of the isolation piles; 3, grouting reinforcement is conducted on the backfill soil area; 4, cover plate construction and back pressure backfilling are conducted; 5, test section tunneling is carried out, and the overall tunneling parameters in the shield side penetrating process are determined; 6, controlling and monitoring the shield side-penetrating tunneling process; and 7, synchronous grouting and secondary reinforcing grouting are conducted in the shield side penetrating tunneling process. By the adoption of the method, the shallow-buried backfill soil area crossing pile foundation construction can be safely and smoothly completed, and obvious influences on the existing pile foundation in a short distance and the surrounding environment of the existing pile foundation are avoided.
本发明具体公开了一种浅埋回填土区盾构近距离侧穿桥梁桩基施工方法，包括如下步骤：步骤1：在桥梁桩基与隧道结构之间施作隔离桩；步骤2：在隔离桩桩顶施作冠梁；步骤3：对回填土区进行注浆加固；步骤4：盖板施作及反压回填；步骤5：进行试验段掘进确定盾构侧穿过程的总体掘进参数；步骤6：盾构侧穿掘进过程控制和监测；步骤7：盾构侧穿掘进过程中同步注浆和二次补强注浆。采用本发明方法可安全、顺利地完成浅埋回填土区穿越桩基施工，并对近距离的既有桩基及其周围环境不造成明显的影响。
