Anti-overturning locking device for single-column-pier curved bridge
The invention discloses a single-column-pier curve bridge anti-overturning locking device which comprises a pier, a steel corbel is fixedly connected to the top of the inner side of the pier, a locking device is fixed to the top of the pier through the steel corbel, the locking device comprises a large steel cylinder, a small steel cylinder is fixedly connected to the top of the large steel cylinder, and a piston is arranged in an inner cavity of the large steel cylinder. A piston rod is fixedly connected to the bottom of the piston, and an anchor head is fixedly connected to the bottom of the piston rod. When an overweight vehicle passes through the bridge in an unbalanced loading mode, the main beam forms bias pressure, and the relative displacement of the pier and the beam can be increased, when the relative displacement exceeds a preset threshold value, the locker conducts automatic locking immediately, the main beam and the pier are temporarily consolidated, and therefore the pier and the main beam jointly bear the anti-overturning effect, the main beam and the support cannot be disengaged, the bridge is prevented from overturning and losing stability, and the service life of the bridge is prolonged. The anti-overturning capacity of the single-column-pier curve bridge can be effectively improved, the bridge is prevented from overturning under the overload and unbalance loading effects, unnecessary casualty accidents are avoided, and economic losses are reduced.
本发明公开了一种独柱墩曲线桥梁抗倾覆锁定装置，包括桥墩，桥墩内侧的顶部固定连接有钢牛腿，锁定器通过钢牛腿和桥墩的顶部固定，锁定器包括大钢筒，大钢筒的顶部固定连接有小钢筒，大钢筒的内腔设置有活塞，活塞的底部固定连接有活塞杆，活塞杆的底部固定连接有锚头。本发明当超重车辆偏载过桥时，主梁形成偏压，墩梁相对位移会增大，当超过预设阈值时，锁定器立即自动锁定，使主梁和桥墩临时固结，从而桥墩和主梁共同承担抗倾覆作用，主梁和支座不会出现脱离的现象，避免桥梁发生倾覆失稳，可有效提高独柱墩曲线桥梁抗倾覆能力，防止桥梁在超载、偏载作用下发生倾覆，避免不必要的伤亡事故发生、减轻经济损失。
