摘要
为切实解决后张法预应力箱梁预制过程中管道预埋穿管和后期钢绞线穿线效率低下的问题,根据项目现场实际情况,自制橡胶抽拔管穿束机、引进了钢绞线穿束机等一系列施工机具,从根本上提高了施工效率,节约了施工成本。
In order to solve the problem of low efficiency of pipeline pre-buried tube wear and late strand threading in the process of precast post tensioned prestressed box girder,according to the actual situation of the scene,the self-made rubber tube threading machine and steel strands machine are introduced.This method improves the efficiency of construction fun-damentally and saves the construction cost.
