Construction method for large-size special-shaped bearing platform of complex riverbed
The invention relates to a construction method for a large-size special-shaped bearing platform of a complex riverbed. The construction method comprises the following steps of cushion layer pouring, pile head cutting, lifting away, bearing platform formwork installation, bearing platform steel bar installation, intelligent temperature control arrangement and bearing platform pouring. The method has the beneficial effects that the stabilizing and lifting-away technology for cutting off the pile head through the girdling method is adopted, the stabilizing support is arranged on the concrete cushion layer on the outer side of the pile head, and the cutting-off and lifting-away stability of the pile head is guaranteed; a post-cast strip integral formwork supporting technology and a fast-splicing large-block set-shaped steel formwork technology are adopted, a set-shaped steel formwork serves as a formwork of the bearing platform, and the problem of supporting of the formwork of the bearing platform is solved by reserving a post-cast strip; a detachable reinforcing steel bar binding jig frame technology of the bearing platform is adopted, in-situ binding is carried out in a bearing platform pouring area, and the in-situ binding precision and efficiency of the bearing platform reinforcing steel bar framework are improved.
本发明涉及一种复杂河床大体积异形承台的施工方法，包括以下步骤：垫层浇筑，桩头切除、吊离，承台模板安装，承台钢筋安装，智能温控布置，承台浇筑。本发明的有益效果是：采用环切法切除桩头的稳固及吊离技术，在桩头外侧的混凝土垫层上设置稳固支架，保证了桩头切除、吊离的稳定性；采用后浇带整体式支模技术和快拼大块定型钢模板技术，将定型钢模作为承台的模板，并通过预留了后浇带，解决了承台模板支护难题；采用承台可拆式钢筋绑扎胎架技术，在承台浇筑区域进行原位绑扎，提高了承台钢筋骨架原位绑扎精度和效率。
