Anti-overturning reinforcing device for single-column type bridge
The invention relates to an anti-overturning reinforcing device for a single-column type bridge, which belongs to the technical field of bridge reinforcing. The device comprise a plurality of short inhaul cables and a plurality of long inhaul cables. The short inhaul cables are evenly arranged on the left side and the right side of the support in the bridge direction, one end of each short inhaulcable is anchored in the main beam through the first anchoring end, and the other end of each short inhaul cable is anchored on the sliding block through a preformed hole in the support; sliding blocks are arranged in sliding grooves, and the sliding grooves are pre-buried in the top face of the pier. The long inhaul cables are arranged on the left side and the right side of the main beam in the bridge direction respectively, one end of each long inhaul cable is anchored in the main beam, the other end of each long inhaul cable penetrates through the main beam and the pier and is anchored in the pier foundation, and steering blocks are arranged at the corners, penetrating through the main beam and the pier foundation, of the long inhaul cables. The reinforcing device further comprises a plurality of hoops embedded in the pier, and a plurality of preformed holes for long inhaul cables to penetrate through are formed in the hoops.
本发明涉及一种独柱式桥梁抗倾覆加固装置，属于桥梁加固技术领域。包括若干短拉索和若干长拉索；若干短拉索均匀布置在支座顺桥向的左右两侧，每根短拉索的一端通过锚固端一锚固于主梁内，另一端通过支座上的预留孔锚固于滑块上；滑块置于滑槽内，滑槽预埋于桥墩的顶面；若干长拉索分别布置在主梁顺桥向的左右两侧，每根长拉索一端锚固在主梁内，另一端穿过主梁以及桥墩并锚固在桥墩基础内，长拉索在穿过主梁以及桥墩基础的转弯处设置有转向块；加固装置还包括镶嵌于桥墩上的若干套箍，套箍上设置有若干穿设有长拉索的预留孔。
