The invention discloses an aqueduct formwork supporting system supported on a bailey beam and a construction method, and belongs to the technical field of aqueduct supporting. The construction methodcomprises the steps that construction preparation is conducted; packway steel pipes are mounted; packway plates are laid; sole timber is arranged; bottom formworks are mounted; outer side formworks are mounted; reinforcement cages are bound, and inner side formworks are erected; concrete is poured, a lower chord of the bailey beam is provided with a hoisting screw rod for hoisting the packway steel pipes, and the packway steel pipes are provided with walking wood plates; the aqueduct bottom formworks are fixed to an upper chord of the bailey beam through high-strength long screw rods and supported through bottom formwork supports, and the upper chord of the bailey beam and the bottom formwork supports jointly form a stable plane truss structure; and the aqueduct bottom formworks and an outer formwork are connected through double steel hinges, and formwork supporting is assisted through opposite-pull screw rods and supporting steel pipes. According to the aqueduct formwork supporting system supported on the bailey beam and the construction method, a construction packway is arranged below the bailey beam, operation of constructors is convenient, aqueduct bottom formworks and the bailey beam are connected firmly, the aqueduct bottom formworks and the outer formwork are connected through the steel hinges, the whole formwork supporting system cannot be laterally bent and twisted, and good economic and technical benefits are achieved.
本发明公开了支承于贝雷梁的渡槽支模体系及施工方法，属于渡槽支撑技术领域。本发明包括施工准备；安装马道钢管；铺设马道板；设置垫木；安装底模板；外侧模板安装；绑扎钢筋笼及支设内侧模板；浇筑混凝土，贝雷梁下弦杆上设置吊拉螺杆吊拉马道钢管，马道钢管上设置行走木板；渡槽底模板通过高强长螺杆固定于贝雷梁上弦杆上，底模板通过底模支架支撑，使贝雷架上弦杆与模板底支架共同形成稳定的平面桁架结构；渡槽底模板与外模通过双片钢铰连接，并通过对拉螺杆及支撑钢管辅助支模。本发明通过雷梁下设施工马道，施工人员作业方便，渡槽底模与贝雷梁连接牢固，渡槽底模与外模钢铰连接，整个支模体系不会发生侧向弯扭具有较好的经济技术效益。
