本发明公开了一种用于空心墩封顶的拉压结合支撑体系，包括简支式提拉框架钢梁承载系统、拉压结合式强支撑体系、提拉模板系统、限位系统、微调系统、防裂系统和防漏浆系统，利用本发明的施工方法在进行空心墩或空心塔封顶时，可以避免人孔预留，极大减少了孔内预留的数量，主要承力构件提拉模板系统为永临结合，加大结构的安全性，减少施工接缝并在墩顶接缝处设置型钢增强连接；拉压结合式强支撑体系为辅助受力体系，减少型钢用量，避免牛腿可能对侧壁混凝土产生的拉应力，通过整体预制和吊装减少空中作业，最大程度保证施工的安全。

The invention discloses a tension and compression combined supporting system for capping a hollow pier. The system comprises a simply supported type lifting frame steel beam bearing system, a tensionand compression combined type strong supporting system, a lifting template system, a limiting system, a fine adjustment system, an anti-cracking system and an anti-slurry leakage system. When the construction method is used for capping the hollow pier or a hollow tower, manholes can be prevented from being reserved, the number of reserved manholes is greatly reduced, a main force-bearing componentlifting formwork system is combined permanently and temporarily, the structural safety is improved, construction joints are reduced, and profile steel is arranged at pier top joints to enhance connection; the tension and compression combined type strong supporting system is an auxiliary stress system, the using amount of profile steel is reduced, the tensile stress possibly generated by a bracketon side wall concrete is avoided, aerial operation is reduced through overall prefabrication and hoisting, and the construction safety is guaranteed to the maximum extent.
