Dismantling method and dismantling device for inclined bridge pier in complex city area
The invention provides a dismantling method and dismantling device for a complex city area inclined bridge pier. The dismantling method for the complex city area inclined bridge pier comprises the steps that S1, drilling is conducted, specifically, mounting holes are evenly drilled in the periphery of the inclined bridge pier; s2, hanging ring pieces are mounted, specifically, connecting screws penetrate through lifting lugs of the hanging ring pieces in a threaded mode and stretch into mounting holes, and the hanging ring pieces and the inclined bridge piers form a whole; s3, a lifting rope is installed, specifically, the lifting rope penetrates through a lifting rope limiting stopper of the lifting ring piece, the end of the lifting rope is fixedly connected with a rope collector, and the rope collector is fixedly connected with a lifting device; s4, cutting and hoisting are conducted, specifically, the inclined bridge pier is cut and hoisted; and S5, the steps S1 to S4 are repeated, and the inclined bridge pier is drilled, the lifting ring piece is installed, the lifting rope is installed, cutting and lifting are conducted in sequence from top to bottom. By means of the complex city area inclined pier dismantling method, it can be guaranteed that the whole inclined pier is dismantled in a segmented mode, and the safety accident that the cut inclined pier slides off and falls off in the cutting or hoisting process is avoided.
本发明提供了一种复杂市域斜桥墩拆除方法及拆除装置，复杂市域斜桥墩拆除方法包括：S1、钻孔：在斜桥墩四周均匀钻安装孔；S2、安装吊环片：连接螺杆螺纹穿过吊环片的吊耳并伸进安装孔，将吊环片与斜桥墩形成一个整体；S3、安装吊绳：吊绳穿过吊环片的吊绳限位器，并将吊绳端部与集绳器固定连接，集绳器与起吊装置固定连接；S4、切割、吊装：对斜桥墩进行切割、吊装；S5、重复步骤S1‑S4，由上至下依次对斜桥墩钻孔、安装吊环片、安装吊绳、切割、吊装。复杂市域斜桥墩拆除方法能够保证对斜桥墩整体的分段拆除，避免切割或吊装的过程中，被切割的斜桥墩滑落和掉落安全事故发生。
