我局在推行后张自锚预应力混凝土中,目前都是杀用混凝土自锚头。豫北建设公司采用纯水泥浆锚头一次压浆法的新工艺,不仅简化了工艺和缩短了工艺周期,而且提高了自锚头的质量和构件端部的抵抗能力。希望我局科研施工部门结合生产学习这一经验,加紧试验研究,给我局杀用这项新工艺创造条件。 In the implementation of post-tensioned self-anchored prestressed concrete, the Bureau is currently killing concrete self-anchor heads. Yubei Construction Company adopts a new process of the primary grouting method with a pure cement slurry anchor head, which not only simplifies the process and shortens the process cycle, but also improves the quality of the self-anchor head and the resistance of the end of the component. I hope that the Bureau of Scientific Research and Construction of the Bureau combined the experience of production and learning, stepped up the experimental research, and created conditions for the Bureau to kill this new process.
