Construction method for double-sliding installation of super-tonnage spherical support of high-speed railway
The invention provides a construction method for double-sliding installation of a super-tonnage spherical support of a high-speed railway. The construction method comprises the following construction steps that scabbling is conducted on the contact face of the top of a support padstone, and the center line of the support is drawn; mounting a cushion stone top fine flat steel plate; installing a transverse sliding I-shaped steel beam, and fixing the transverse sliding I-shaped steel beam with a pier top embedded bolt; a double-spliced transverse sliding bailey beam is installed, the double-spliced bailey beam is assembled on the pier top, four I-shaped steel bolts are connected to form a frame beam, and the rear portion of the frame beam is anchored to the pier top embedded bolts; mounting a bailey beam top longitudinal sliding lifting frame and a lifting system; the support is placed on a pier bottom lifting platform, and the support is lifted to the position above the top elevation of a padstone through a lifting system; and after the support is lifted in place, the support slides and is aligned front, back, left and right, and after alignment, the support is placed on the padstone. The method can solve the problems that a large number of sub-projects of complex structures are independently and crossly operated, field working conditions are limited, large hoisting equipment cannot be in place for cooperation for a long time, and the lease fee of the large hoisting equipment is high.
本发明提供一种用于高速铁路超大吨位球形支座双滑移安装的施工方法，包括如下施工步骤：对支座垫石顶接触面凿毛并画出支座中心线；安装垫石顶精平钢板；安装横向滑移工字钢横梁，使其与墩顶预埋螺栓固定；安装双拼横向滑移贝雷梁，在墩顶组装双拼贝雷梁，通过4道工字钢螺栓连接形成框架梁，框架梁后部锚固于墩顶预埋螺栓；安装贝雷梁顶纵向滑移吊装架以及提升系统；将支座放置在墩底提升平台，通过提升系统将支座提升至垫石顶标高以上；支座提升到位后将支座滑移，前后左右对正，对正后，将支座放置到垫石上。本发明可解决复杂构筑物大量分项工程独立交叉作业、现场工况受限大型起重设备无法长时间就位配合、大型起重设备租赁费高等问题。
