Prestress concrete box girder end sealing formwork construction method
The invention relates to the field of concrete box girder construction, in particular to a prestress concrete box girder end sealing formwork construction method. The method includes the steps that formworks are arranged at the bottom of the position between a concrete bridge and an adjacent girder, on the inner side and the outer side of a web and on the end face of the girder respectively and include a bottom plate formwork, web inner and outer side formworks and an end formwork; the bottom plate formwork and the web formworks are in lap joint, and the outer edge of the bottom plate formwork is attached to the end formwork and is connected with the end formwork through bolts; the formworks are supported, and an integral mould is formed through a sealed space formed by the bottom plate formwork, the web inner and outer side formworks, the end formwork and a poured girder end; concrete is lifted to the girder surface through a small material elevator, is transferred through a hopper and is poured, and the concrete is vibrated and compacted through a small vibrating rod. By means of the prestress concrete box girder end sealing formwork construction method, the work period is short, operation is convenient, efficiency is high, cost investment is little, and pollution is reduced.
