D-shaped auxiliary beam double-railway overhead beam moving method
The invention discloses a D-shaped auxiliary beam double-railway overhead beam moving method, which belongs to the technical field of road and bridge engineering and comprises the following steps: S1, erecting a D-shaped auxiliary beam; s2, a transverse strip-shaped foundation pit is excavated; s3, buttresses are erected, and hole digging piles are excavated; s4, hoisting and lowering the reinforcement cage; s5, concrete is poured to form a strip-shaped foundation; s6, the D-shaped auxiliary beam is moved to the strip-shaped foundation; s7, the construction foundation pit is excavated, two rows of construction foundation pit hole digging protection piles are constructed, and the prefabricated protection piles are put down; s8, crown beam construction; s9, four longitudinal beams are fixed between the top beams of the two rows of prefabricated guard piles and the cross beams of the D-shaped auxiliary beams through angle steel and U-shaped clamps correspondingly, and the supporting strength of the longitudinal beams is improved through pull rod supporting; s10, the original D-shaped auxiliary beam is dismantled and longitudinally moved and reinstalled; according to the method, temporary backfilling of the ballast bed around the pile position for railway recovery is not needed, the risk of train shaking caused by substandard roadbed backfilling quality is eradicated, meanwhile, interference to train operation is reduced, and material waste can be eradicated.
本发明公开了D型便梁双重铁路架空移梁方法，属于道路桥梁工程技术领域，包括以下步骤：S1：架设D型便梁；S2：开挖横向条形基础基坑；S3：架设支墩开挖挖孔桩；S4：吊装下放钢筋笼；S5：浇筑混凝土形成条形基础；S6：将D型便梁移至条形基础上；S7：开挖施工基坑，两排施工基坑挖孔防护桩施工，下放预制防护桩；S8：冠梁；S9：通过角钢和U型卡分别将四根纵梁固定在两排预制防护桩冠梁和D型便梁的横梁间，通过拉杆支撑提高纵梁支撑强度；S10：拆除、纵移原D型便梁并重新安装；本发明无需临时回填桩位周边道床恢复铁路，杜绝路基回填质量不达标造成列车晃车风险发生，同时减少对列车运营的干扰，而且能够杜绝材料的浪费。
