Single-column pier beam bridge and reinforcing and reconstructing method thereof
The invention relates to a single-column pier beam bridge and a reinforcement and transformation method of the single-column pier beam bridge, and belongs to the technical field of bridge reinforcement and transformation. The method comprises the following steps: (1) measuring an inclination angle between a main beam side part and a pier side part; (2) prefabricating an anti-overturning device, wherein the anti-overturning device comprises a wedge-shaped mother plate, a pull rod clamping groove and a pull rod; (3) driving anchor bolts into the preset positions of the side surface parts, and fixing the upper wedge-shaped mother board and the lower wedge-shaped mother board on the corresponding side surface parts by using nuts; (4) the two expansion ends of each pull rod are clamped into thegroove cavities of the upper pull rod clamping groove and the lower pull rod clamping groove from the open ends of the clamping grooves, and movable gaps can be reserved between the two expansion ends of each pull rod and the cavity walls of the corresponding clamping groove cavity; and (5) filling a groove cavity of the pull rod clamping groove with a non-hydrophilic lubricant, and sealing the groove cavity of the pull rod clamping groove to form a sealed cavity. The reinforcement and transformation method is convenient to construct, low in cost and convenient to replace in the subsequent maintenance process, and can be widely applied to the field of bridge reinforcement and transformation.
本发明涉及一种单柱式桥墩梁式桥及单柱式桥墩梁式桥的加固改造方法，属于桥梁加固改造技术领域。该方法包括：(1)测量主梁侧面部与桥墩侧面部的倾斜角度；(2)预制抗倾覆装置，包括楔形母板、拉杆卡槽及拉杆；(3)在前述侧面部的预定位置处打入锚固螺栓，并利用螺母将上下两楔形母板固定在对应的侧面部上；(4)将将拉杆的两膨胀端部从卡槽敞口端处卡入上下两个拉杆卡槽的槽腔内，且使每个拉杆的两膨胀端部与其所卡持槽腔的各腔壁间均能存有活动间隙；(5)在拉杆卡槽的槽腔内填充非亲水润滑剂，并将拉杆卡槽的槽腔封口成密封腔。该加固改造方法不仅便于施工、成本低，且便于后续维护过程中的更换，可广泛应用于桥梁的加固改造领域中。
