Prefabricated and assembled railway pier structure based on concrete-filled steel tube framework
The invention discloses a prefabricated assembly railway pier structure based on a concrete filled steel tube framework, and belongs to the technical field of pier constructions.The assembly structure is simple in structure, a bearing platform, a pier section and a cover beam which are prefabricated are sequentially hoisted, positioning parts pre-buried in a prefabricated part are in up-down butt joint, and a direct pressurizing pump pressurizing mode is adopted, so that the prefabricated assembly railway pier structure is obtained. The grouting material is driven into the input hole, moves downwards along the interior of the pouring steel pipe, bypasses the sinking hole, moves upwards along the inner hole and finally flows out of the output hole, the inner hole and the pouring steel pipe are filled with the grouting material at the moment, and after the grouting material is solidified, integration of the bearing platform, the pier column section and the bent cap is achieved; according to the structure, positioning is convenient and fast, prefabricated parts are connected through grouting materials, the number of input positions of the grouting materials is small, the grouting materials are all arranged at the position of the bent cap, pouring at each connecting point is not needed, pouring of the grouting materials of all pier column structures can be completed, the pouring mode is simple, filling of the grouting materials is guaranteed, and the structure is high in construction efficiency and tight and stable in connection.
本发明公开了一种基于钢管混凝土骨架的预制拼装铁路桥墩结构，属于桥墩建筑技术领域，此拼装结构，结构简单，通过依次将预制完成的承台、桥墩节段以及盖梁吊装，并将预埋在预制件中的定位部上下对接，通过直接加压泵加压的方式，将灌浆料打入输入孔，灌浆料沿浇筑钢管内下移，绕过下沉孔，并沿内孔上移，最终从输出孔流出，此时灌浆料充满了内孔和浇筑钢管，待灌浆料凝固后，承台、墩柱节段以盖梁实现一体化；此结构，定位方便快捷，通过灌浆料将预制件连接，灌浆料输入位置少，均开设在盖梁位置，不需在每个连接点浇筑，即可完成所有墩柱结构的灌浆料浇筑，浇筑方式简单，并且保证了灌浆料的充满，此结构的施工效率高，连接紧密稳固。
