预应力加固技术能够避免公路桥梁结构由于震动等因素而导致的局部裂缝,还可以减小桥梁挠度,从而能够将受力合理地分配在桥梁上,因此,被广泛应用于桥梁工程中。本文首先对预应力加固进行概述,在此基础上从施工放样、水泥砂浆的制备、上锚固点设置、滑块的施工、预应力筋的施工、防腐处理等方面阐述了预应力加固技术的应用。
Prestressed reinforcement technology can avoid local cracks caused by vibration and other factors and reduce the deflection of the bridge, so that the stress can be rationally distributed on the bridge. Therefore, it is widely used in bridge engineering. In this paper, an overview of prestressing reinforcement is given. Based on this, the application of prestressing reinforcement technology is described from the aspects of construction setting, preparation of cement mortar, setting of anchorage point, construction of slider, construction of prestressing tendons and anticorrosive treatment .
