Construction technology combining suspended support construction and overhanging reverse hoisting construction

The invention provides a construction technology combining suspended support construction and overhanging reverse hoisting construction. The construction technology comprises the following steps that a safe and reliable anchoring platform is constructed; the steel truss system is overhung and reversely hung on the anchoring platform; and the double-box double-chamber cast-in-place continuous beam is constructed. A suspended support is adopted for capping beam pouring, fine rolled steel is pre-buried on a capping beam, and after the capping beam pouring is completed and the strength is achieved, four steel trusses are installed for overhanging and reverse hoisting so as to complete subsequent construction of the double-box double-chamber cast-in-place continuous beam. 本发明提供了一种悬空支架与悬挑反吊施工相结合的施工工艺，包括以下步骤：构建安全可靠的锚固平台；钢桁架系统悬挑反吊于锚固平台；施工双箱双室现浇连续梁。本发明采用悬空支架进行盖梁浇筑，盖梁上预埋精轧钢，盖梁浇筑完成达到强度后安装四根钢桁架悬挑反吊以完成双箱双室现浇连续梁的后续施工。
