Positioning method and positioning tool for inner shrinkage type lining pipe corrugated pipe
The invention relates to the technical field of bridge engineering beam plate prefabricated parts and prefabricated structures adopting pre-stress post-tensioning construction, and particularly discloses a positioning method for a corrugated pipe of an internal shrinkage type lining pipe, which comprises the following steps of: coarse positioning of the corrugated pipe: reserving a hole channel for arranging the corrugated pipe in advance when a steel reinforcement framework is manufactured; making a corrugated pipe with a lining pipe and of an inward shrinkage type structure penetrate into the duct for arranging the corrugated pipe; after the whole reinforcement cage is hoisted into the formwork, adjusting the line shape of the corrugated pipe, and fixing the corrugated pipe to the design position; and the lining pipe of the corrugated pipe is locked with the template. The corrugated pipe inner shrinkage type non-exposed structural form is adopted, outer side mold hole channels are reduced, the influence on the rigidity of an outer side mold is relieved, the overall stability is ensured, meanwhile, it is ensured that cutting is not needed in the side face circumferential conflict steel bar prefabricating process, and the steel bar erecting effect is achieved; when the reinforcement cage is bound, the corrugated pipe is coarsely positioned, the corrugated pipe is accurately positioned after entering a mold, and a multi-stage positioning measure is formed to ensure the accuracy of the line shape and position of the corrugated pipe.
本发明涉及桥梁工程梁板预制构件及预制结构采用预应力后张施工的技术领域，具体公开了一种内缩式内衬管波纹管定位方法，包括：波纹管粗定位：在钢筋骨架制作时提前预留波纹管设置用孔道，将带有内衬管的内缩式结构的波纹管穿入波纹管设置用孔道中；波纹管精确定位：钢筋骨架整体吊入模板后,调整波纹管线形，将波纹管固定到设计位；将波纹管的内衬管与模板锁定。本发明采用了波纹管内缩式不外露结构形式，减少了外侧模孔道，减轻了对外侧模刚度影响，确保整体稳定性，同时也保证了侧面环向冲突钢筋预制过程中不切割，起到钢筋架立作用；钢筋笼绑扎时波纹管粗定位，入模后波纹管精确定位，形成多级定位措施以保证波纹管线形及位置精确。
