Hollow slab girder bridge shear-resistant reinforcing method under uninterrupted traffic condition
The invention relates to the technical field of bridge reinforcement, in particular to a hollow slab girder bridge shear reinforcement method without interrupting traffic, which comprises the following steps: S1, detecting and marking the position of a steel bar at the bottom of a hollow slab girder; s2, probing the current condition of the inner cavity of the hollow slab; a strip-shaped notch is formed in the bottom of the hollow slab beam, a partition structure is constructed in the inner cavity of the hollow slab through the strip-shaped notch, the partition structure divides the inner cavity of the hollow slab into a vacant area and two grouting areas, the vacant area is defined by the two partition structures, and the grouting areas are arranged close to the supporting beam pier; a grouting hole is formed in the hollow slab beam bottom, and a grouting filling material is input into the grouting area through the grouting hole till the grouting area is filled with the grouting filling material; s5, groove and hole repairing is conducted, specifically, the strip-shaped groove openings, the grouting holes and the exhaust holes are repaired; the hollow slab beam can be reinforced on the premise that traffic is not blocked, so that the cross section of the main beam is increased, the rigidity of the main beam is improved, the mechanical property of the main beam is improved, and the shearing resistance of the hollow slab is improved.
本申请涉及桥梁加固技术领域,尤其涉及一种不中断交通条件下的空心板梁桥抗剪加固方法,包括S1:空心板梁底钢筋位置探测并标记;S2:空心板内腔现况探查;S3:内腔隔断:空心板梁底开设条形槽口,并通过条形槽口于空心板内腔中施作分隔结构,分隔结构将空心板内腔分隔为空置区和两个灌浆区,其中空置区由两个分隔结构围成,灌浆区靠近支撑梁墩设置;S4:开孔注浆:空心板梁底上开设注浆孔,并通过注浆孔向灌浆区内输入灌浆填充材料,直至注满;S5:槽、孔修补:将条形槽口、注浆孔以及排气孔进行修补;本申请具有可以在不阻断交通的前提下加固空心板梁,以此来增大主梁截面、提高主梁刚度,改善主梁力学性能,提高空心板抗剪性能的效果。
