Formwork structure of cast-in-place arch small box chamber and construction method
The invention provides a formwork structure of a cast-in-place arch small box chamber and a construction method. The formwork structure comprises a plurality of box chamber cavities; the box chamber cavities are distributed in the main arch ring, and each box chamber cavity is internally provided with a profiling formwork component, a supporting tire film and a plurality of tire film positioning and supporting assemblies. A profiling template component is arranged at the part, in contact with a web plate and a top plate of the main arch ring, of the outer contour of each box chamber cavity; each box chamber cavity is filled with a supporting tire membrane, the tire membrane positioning and supporting assemblies are arranged in the supporting tire membranes and abut against the profiling formwork components, and the bottoms of the tire membrane positioning and supporting assemblies are pre-buried in a bottom plate of the main arch ring; a sludge discharge channel is formed in the bottom of each box chamber cavity, and a water inlet channel is formed in the top of each box chamber cavity. The top and the bottom of each box chamber cavity are respectively provided with the water inlet channel and the sludge discharge channel, so that the supporting tire membrane is smoothly dismounted, the dismounting difficulty is greatly reduced, and the construction efficiency is improved while the self weight of the box chamber cavities is reduced.
本发明提供了一种现浇拱小箱室的模板结构及施工方法,包括：若干箱室腔体；各箱室腔体分布在主拱圈内，每个箱室腔体内均具有压型模板构件、支撑胎膜和若干胎膜定位支撑组件；每个箱室腔体的外轮廓处与主拱圈的腹板和顶板接触的部位均设置有压型模板构件；每个箱室腔体内填充有支撑胎膜，胎膜定位支撑组件设置在支撑胎膜内，且胎膜定位支撑组件与压型模板构件相抵接，胎膜定位支撑组件的底部预埋于主拱圈的底板中；每个箱室腔体的底部开设有排泥通道，每个箱室腔体的顶部开设有进水通道。本发明通过在每个箱室腔体的顶部和底部分别开设进水通道和排泥通道，以实现支撑胎膜的顺利拆除，大大降低了拆除难度，降低箱室腔体自重的同时提高了施工效率。
