Fabricated prestressed concrete box girder swivel bridge girder erection machine and construction method
The invention relates to a fabricated prestressed concrete box girder swivel bridge girder erection machine and a construction method. An existing swivel method has large interference on railway operation in the swivel bridge construction process. In the swivel bridge girder erection machine, a swivel bridge girder erection machine tower is arranged at the top of a swivel bridge girder erection machine tower lower cross beam, and a swivel bridge girder erection machine bridge deck beam frame is horizontally arranged below the swivel bridge girder erection machine tower lower cross beam and is longitudinally arranged; the swivel bridge girder erection machine stay cables are symmetrically arranged on the two longitudinal sides of the swivel bridge girder erection machine tower, the top ends of the swivel bridge girder erection machine stay cables are fixed to the side faces of the swivel bridge girder erection machine tower, and the bottom ends are fixed to the top of the swivel bridge girder erection machine bridge deck beam frame. The swivel bridge girder erection machine lower supporting legs are arranged at the bottoms of the two transverse ends of the swivel bridge girder erection machine tower lower cross beam, and auxiliary swivel parts are arranged at the bottoms of the swivel bridge girder erection machine lower supporting legs. According to the invention, the whole bridge can be rotated in place at one time without passing through holes for several times, and the beam erecting time is controlled within one skylight point; beam part rotation and pier body rotation can be achieved, universality is good, the construction period is short, and interference to railway operation is small.
本发明涉及一种装配式预应力混凝土箱梁转体架桥机及施工方法。现有转体方法在转体桥施工过程中对铁路运营干扰较大。本发明的转体架桥机中，转体架桥机塔架设置在转体架桥机塔架下横梁的顶部，转体架桥机桥面梁架水平设置在转体架桥机塔架下横梁的下方并纵向布置；转体架桥机斜拉索在转体架桥机塔架的纵向两侧对称设置，顶端固定在转体架桥机塔架的侧面，底端固定在转体架桥机桥面梁架的顶部；转体架桥机下支腿设置在转体架桥机塔架下横梁的横向两端底部，转体架桥机下支腿底部设置有辅助转体件。本发明可实现整幅桥一次转体就位，不需分次过孔，架梁时间控制在一个天窗点内；可实现梁部转体和墩身转体，通用性好，施工周期短、对铁路运营干扰小。
