Guiding and positioning structure and steel cofferdam construction structure

The utility model provides a guiding and positioning structure and a steel cofferdam construction structure, and relates to the technical field of building construction. The guiding and positioning structure comprises a pile casing, a guiding cylinder and a positioning plate, the pile casing is embedded in a preset pile position, the guiding cylinder is fixedly arranged on the outer side of the pile casing, a groove is formed in one side of the positioning plate, the other side of the positioning plate is fixed to a workpiece, and the guiding cylinder is arranged in the groove in a penetrating mode. The guide cylinder is sleeved with the groove, the workpiece sinks in the extending direction of the guide cylinder under the limitation of the guide cylinder, the situation that the sinking position of the workpiece deviates due to water buoyancy is avoided, construction precision is improved, and hoisting potential safety hazards are reduced. 本申请提供一种导向定位结构及钢围堰施工结构，涉及建筑施工技术领域。导向定位结构包括护筒、导向筒和定位板，护筒埋设于预设桩位处，导向筒固定设置
