Novel prefabricated-cast-in-place combined reinforced concrete hollow pier and implementation method
The invention relates to a novel prefabricated-cast-in-place combined reinforced concrete hollow bridge pier and an implementation method, the novel prefabricated-cast-in-place combined reinforced concrete hollow bridge pier comprises a bridge pier segment piece, the top of the bridge pier segment piece is connected with a cap beam, the bottom of the bridge pier segment piece is connected with a bridge pier inner groove segment piece, the bottom of the bridge pier inner groove segment piece is connected with a bridge pier splicing piece, and the bottom of the bridge pier splicing piece is connected with a cast-in-place bearing platform; a plurality of vertical corrugated pipe hole channels are formed in the peripheries of the bridge pier segment pieces, the bridge pier inner groove segment pieces and the bridge pier splicing pieces, prestressed steel bars penetrate through the inner sides of the vertical corrugated pipe hole channels, the top ends of the prestressed steel bars are fixed to the upper portion of the cap beam, and the bottom ends of the prestressed steel bars are fixed to the lower portion of the cast-in-place bearing platform. According to the prefabricated reinforced concrete bridge pier, the structural bearing capacity and light weight are guaranteed, meanwhile, the anti-seismic property of the prefabricated reinforced concrete bridge pier is improved, the mechanization level of engineering construction is improved, manpower and material resources are saved, energy consumption is low, and environmental pollution is small.
本发明是一种新型预制‑现浇结合钢筋混凝土空心桥墩及实施方法，包括桥墩节段片，桥墩节段片顶部连接有帽梁，桥墩节段片底部连接有桥墩内槽节段片，桥墩内槽节段片底部连接有桥墩拼装片，桥墩拼装片底部连接有现浇承台，桥墩节段片、桥墩内槽节段片和桥墩拼装片四周均设有若干竖向波纹管孔道，竖向波纹管孔道内侧穿设有预应力钢筋，预应力钢筋顶端固定在帽梁上部，预应力钢筋底端固定在现浇承台下部。本发明保证了结构承载力、轻质的同时，提高了预制钢筋混凝土桥墩的抗震性能，提高了工程建设的机械化水平，节省了人力物力，耗能低、环境污染小。
