Steel cofferdam system for bridge pier maintenance and reinforcement and mounting method of steel cofferdam system
The steel cofferdam system comprises a steel cofferdam, a water stopping system, an inner supporting system and an overhead rail system, the steel cofferdam is of a sealed cylindrical structure and arranged on the periphery of a bearing platform in a surrounding mode, and the water stopping system is arranged at the bottom of the steel cofferdam and used for sealing the bottom of the steel cofferdam; the inner supporting system is supported on the inner side of the steel cofferdam in a layered mode and used for resisting water pressure on the outer side of the steel cofferdam, the hanger rail system is arranged on the bottom face of the main beam and annularly arranged in a circle along the position over the steel cofferdam, and the hanger rail system is used for hanging the steel cofferdam and adjusting the elevation and the plane position of the steel cofferdam. The invention further discloses a mounting method of the steel cofferdam for bridge pier maintenance and reinforcement. The water stopping air bag which is arranged at the bottom of the cofferdam and tightly attached to the surface of the original bearing platform is used for inflating and stopping water, the problems that cofferdam bottom sealing concrete consumes materials and is difficult to dismantle are solved, and the problem that the operation space is limited when the steel cofferdam for reinforcing an old bridge is installed and dismantled in blocks at the bridge site is solved through the overhead rail system arranged at the beam bottom.
本发明公开了一种桥墩维修加固用钢围堰系统，包括钢围堰、止水系统、内支撑系统和吊轨系统，所述钢围堰为密封的筒状结构且围设于承台外周，所述止水系统设置于所述钢围堰底部用于对钢围堰底部进行密封，所述内支撑系统分层支撑于钢围堰内侧用于抵抗钢围堰外侧水压力，所述吊轨系统设置于主梁底面并沿钢围堰正上方环向设置一圈，所述吊轨系统用于吊挂钢围堰并调节钢围堰标高和平面位置。本发明还公开了一种桥墩维修加固用钢围堰的安装方法。本发明通过设置于围堰底部紧贴在原承台表面的止水气囊充气止水，解决围堰封底混凝土消耗材料且拆除困难的问题，通过设置于梁底的吊轨系统解决旧桥加固用钢围堰在桥位处分块安装拆除作业空间受限的问题。
