高边坡黏结式端锚型预应力锚索快速锚固张拉施工技术OA

In response to the pain points of low construction efficiency and long maintenance period of traditional prestressed anchor cables for high slopes,this study focuses on the core technology of fast anchoring and tensioning of adhesive end anchored prestressed anchor cables based on the tailwater outlet slope project of a hydropower station.Through the application of new high-strength materials,adaptation of specialized equipment,and optimization of construction processes,a complete technical system covering"materials equipment processes quality control"has been formed,achieving a breakthrough in tensioning on the day of grouting in the anchoring section.On site engineering practice has shown that this technology can shorten the construction period of single bundle anchor cables to 3-4 days,with a compressive strength of over 40 MPa within 24 hours and a stress loss of≤8%after 48 hours of tension locking.It provides a replicable technical solution for rapid construction of high slope anchor cables.
