Construction method for post-tensioned prestressing of concrete box girder
The invention discloses a post-tensioned prestress construction method for a concrete box girder, which combines the construction of municipal bridge reinforcement engineering and municipal bridge prestress engineering according to the characteristics of municipal bridge engineering. Municipal bridge reinforcing steel bar binding, municipal bridge prestressed corrugated pipe positioning and mounting, municipal bridge concrete pouring, municipal bridge prestressed tensioning, municipal bridge prestressed grouting and municipal bridge prestressed anchor sealing are controlled, the problem that municipal bridge prestress is insufficient is solved fundamentally, meanwhile, working procedure interpenetration can be effectively conducted, and the construction efficiency is improved. The construction efficiency is improved, the labor cost is saved, the construction period is shortened, the construction process is adjustable, the construction quality is improved, and certain economic benefits are achieved.
本申请公开了一种混凝土箱梁后张预应力的施工方法，根据市政桥梁工程的特点，将市政桥梁钢筋工程和市政桥梁预应力工程的施工相结合，通过对市政桥梁钢筋绑扎、市政桥梁预应力波纹管定位安装、市政桥梁混凝土浇筑、市政桥梁预应力张拉、市政桥梁预应力压浆、市政桥梁预应力封锚进行控制，从根源上解决了市政桥梁预应力不足的难题，同时，可有效进行工序穿插，提高施工效率、节约人工成本、缩短工期、施工过程可调整、提高施工质量，具有一定的经济效益。
