为满足桥梁施工质量的稳定性和耐久性,在后张预应力T梁施工中,采用真空辅助压浆工艺等技术进行预应力孔道压浆已经越来越普及,但很多现场技术人员对该工艺的基本原理、工艺特点特性以及具体的施工方法还很陌生,在施工中如何进行质量控制还生疏。
In order to meet the stability and durability of bridge construction quality, it is more and more popular to apply prestressed hole grouting technology by vacuum assisted grouting technology in the post-tensioned prestressed T-beam construction. However, many on-site technicians have studied the technology The basic principles, characteristics and process characteristics of concrete construction methods are still very strange, how to carry out quality control in construction is also unfamiliar.
