Pile foundation lowering reinforcement cage supporting and positioning structure

The utility model provides a pile foundation lowering reinforcement cage supporting and positioning structure, and relates to the technical field of building construction. Comprising a mounting plate and a supporting rod, a positioning hole is formed in the mounting plate, a positioning mechanism is arranged on the mounting plate, the positioning mechanism comprises a reciprocating lead screw, a second fixing plate, a third fixing plate, a sliding block, a connecting rod, a positioning plate and a limiting rod, and the positioning mechanism is connected with a driving mechanism. The driving mechanism comprises a first sleeve, a second sleeve, a first bevel gear, a second bevel gear, a gear ring, a transmission gear and a driving motor. Through the arrangement of the positioning mechanism and the driving mechanism, the problem that an existing reinforcement cage supporting and positioning structure is poor in positioning effect is solved. 本实用新型提供一种桩基下放钢筋笼支撑定位结构，涉及建筑施工技术领域。包括安装板、支撑杆，所述安装板上开有定位孔，所述安装板上设有定位机构，所述定
