Erecting method of pier-beam integrated construction bridge girder erection machine
The invention relates to the technical field of bridges, and provides an erecting method of a pier-beam integrated construction bridge girder erection machine, the bridge girder erection machine comprises a main truss, the main truss is provided with a moving device, the main truss comprises a first section, a second section, a third section and a fourth section from front to back in the walking direction, and the longitudinal middle part of the top surface of the main truss is provided with a bridge tower; a plurality of inhaul cables are connected between the bridge tower and the main truss, and all the inhaul cables are connected to the top of the bridge tower; the method comprises the following steps that a, the bridge girder erection machine is moved to enable the third section and the fourth section to be supported on a main beam or a bent cap of an installed beam section, the second section is supported on a bent cap of a non-installed beam section, and the first section is fixed after being in a cantilever state; and b, the main beam to be installed, the cover beam and the pier to be installed are transported forwards from the fourth section through the main truss to be installed. The upper structure and the lower structure of the bridge can be constructed through the bridge girder erection machine, construction roads are not needed or reduced, and the construction period is obviously shortened.
本发明涉及桥梁技术领域，提供了一种墩梁一体化施工架桥机的架设方法，架桥机包含主桁架，所述主桁架具有移动装置，所述主桁架沿行走方向从前至后包含第一段、第二段、第三段和第四段，所述主桁架顶面的纵向中部具有桥塔，所述桥塔和主桁架之间连接有若干拉索，所有所述拉索均连接于所述桥塔顶部；包含如下步骤：a、移动所述架桥机使所述第三段和第四段支撑在已安装梁段的主梁或盖梁上、所述第二段支撑在未安装梁段的盖梁上、所述第一段呈悬臂状态后固定；b、通过主桁架从所述第四段向前运输待安装的主梁、盖梁和待安装的桥墩进行安装。本装置对桥梁的上部结构和下部结构均能采用架桥机施工，无需或减少施工便道，且明显缩短施工工期。
