Temporary pier device of large-span ultra-wide double cable plane cable-stayed bridge
The invention provides a large-span ultra-wide double-cable-plane cable-stayed bridge temporary pier device which comprises at least two anchoring platforms, distribution beams are arranged at the top ends of the anchoring platforms and used for being connected with steel girders, parallel connection supports are connected between the anchoring platforms to form a temporary bearing platform, anchor pulling platforms are arranged on the two sides of the temporary bearing platform, and inhaul cables are further arranged on the temporary bearing platform. The two ends of the inhaul cable are connected with the temporary bearing platform and the anchor pulling platform respectively, and the problems of main beam vibration, horizontal deflection and torsion instability caused by horizontal crosswind are solved.
本申请提供一种大跨度超宽幅双索面斜拉桥临时墩装置，包括至少两个锚固平台，锚固平台顶端设有分配梁，分配梁用于连接钢主梁，锚固平台之间连接有平联支撑以组成临时承重台，临时承重台两侧设有拉锚平台，还设有拉索，拉索两端分别连接临时承重台和拉锚平台，解决了水平横风导致主梁振动、水平偏转、扭转失稳的问题。
