Non-thrust arch bridge arch foot pre-embedding construction method
The invention relates to a non-thrust arch bridge arch foot pre-burying construction method. The method comprises the steps of bearing platform leveling cushion layer construction, foundation frame on-site fixing, foundation cushion layer construction, fixed end on-site installation, inclined strut fixing frame on-site installation, bearing platform pre-burying cushion layer construction and pre-burying arch rib hoisting construction. The method has the beneficial effects that the foot margin frame and the foot margin cushion layer can be applied to installation of all arch foot embedded parts, and the procedure of independently manufacturing various supports is avoided; a manner of embedding the foot margin frame, the fixed end and the fixed frame is adopted to replace an embedded bracket, so that the mounting precision of the embedded part is improved; the foundation frame, the fixing end and the fixing frame are embedded and fixed in a three-cushion-layer pouring mode, and the stability of the embedded part during installation is improved; the arch rib high-low frame and the arch rib tripod can be detached and recycled.
本发明涉及一种无推力拱桥拱脚预埋施工方法，包括步骤：承台找平垫层施工、地脚框格架现场固定、地脚垫层施工、固定端现场安装、斜撑固定架现场安装、承台预埋垫层施工、预埋拱肋吊装施工。本发明的有益效果是：地脚框格架、地脚垫层可以应用于所有拱脚预埋件的安装，避免了单独制作各类支架的工序；采用地脚框格架、固定端、固定架预埋的方式取代预埋支架，提高了预埋件的安装精度；分三层垫层浇筑的方式来对地脚框格架、固定端及固定架进行嵌固处理，提升了预埋件安装时的稳定性；拱肋高低架和拱肋三脚架能够拆除回收。
