The invention discloses a guide device for lowering and positioning a double-wall steel cofferdam. The guide device comprises a guide wheel, a connecting rod, a moving frame, a pushing device and a counter-force frame, wherein the guide wheel is fixedly connected to the moving frame through the connecting rod, the pushing device is arranged between the moving frame and the counter-force frame, andthe pushing device is used for adjusting the position of the moving frame; and the counter-force frame is fixedly connected to a horizontal straight rod on the side wall of a steel casing, and the guide wheel makes contact with the cofferdam. By means of the structural design of the guide device, the stability of the double-wall steel cofferdam in the lowering process can be guaranteed, active deviation rectification can be conducted when the position of the double-wall steel cofferdam deviates, meanwhile water flow impact can be resisted to reduce the horizontal shearing force borne by a pull rod, and the guide device has the advantages of high adaptability, high automation level, clear stress relation, easiness in operation, low construction cost and the like.
本发明公开了一种用于双壁钢围堰下放定位的导向装置，所述导向装置包括导向轮、连接杆、移动架、顶推装置和反力架，所述导向轮经连接杆固定连接于所述移动架之上，所述顶推装置设置于所述移动架与反力架之间，用于完成移动架的位置调节；所述反力架固定连接于钢护筒侧壁上的水平直杆之上，所述导向轮与围堰相接触。通过本发明导向装置的结构设计既可保证双壁钢围堰下放过程中的稳定性，又可在双壁钢围堰位置出现偏差时进行主动纠偏，同时可以抵抗水流冲击以减小拉杆所承受的水平剪力，具有适应性强、自动化水平高、受力关系明确、易于操作且施工成本低等优点。
