Construction method for bridge abutment in canyon cliff zone
The invention discloses a canyon cliff zone bridge abutment construction method which comprises the following steps: building a bridge abutment construction platform: firstly installing a group of triangular stabilizing brackets on a cliff rock surface of a construction platform area; the steps are repeated, multiple sets of triangular stable supports are evenly distributed and installed in the length direction of the cliff rock surface, distribution beams are fixed between horizontal cross beams in the multiple sets of triangular stable supports, and scaffold boards are laid on the tops of the distribution beams to form a bridge abutment construction platform; bridge abutment diagonal bracing support and formwork construction is conducted on the built bridge abutment construction platform; and bridge abutment cantilever beam support and formwork construction is conducted on the built bridge abutment construction platform. According to the construction method, the special bridge abutment construction platform is firstly built, then bridge abutment diagonal bracing support and formwork construction and bridge abutment cantilever beam support and formwork construction are conducted on the bridge abutment construction platform, the bridge abutment construction platform is supported by the multiple sets of triangular stable supports, and compared with scaffold steel pipes built temporarily, the construction efficiency is greatly improved; and good safety and stability are achieved, and safety is ensured.
本发明公开了一种峡谷峭壁地带桥台施工方法，包括以下步骤，搭建桥台施工平台：在施工平台区域的悬崖岩面先安装一组三角稳定支架；重复上述步骤，沿悬崖岩面的长度方向均布安装多组三角稳定支架，在多组三角稳定支架中的水平横梁之间固定分配梁，在分配梁的顶部铺设脚手板形成桥台施工平台；在搭建好的桥台施工平台进行桥台斜撑支架及模板施工；在搭建好的桥台施工平台进行桥台悬挑梁支架及模板施工。本发明首先搭建专门的桥台施工平台，然后分别在桥台施工平台上进行桥台斜撑支架及模板施工以及进行桥台悬挑梁支架及模板施工，桥台施工平台采用多组三角稳定支架进行支撑，相比于临时搭建的脚手架钢管来说，具有良好的安全稳定性能，确保安全。
