摘要
为了解决隧道内预应力锚索钻孔、安装和注浆施工难度大、浆液强度增长慢、锚索锚固力难以保证的技术难题,通过钻机选型、增设锚固结、优化注浆液和注浆顺序等措施,既加快了锚索施工进度,又保证了锚索的施工质量。可以为类似工程起到一定借鉴参考作用。
In order to solve the technical problems of pre-stressed anchor cable in tunnel such as the difficulty of drilling,installing and grouting,the slow growth of slurry strength and the difficulty of guaranteeing anchor force,through the selection of drilling rigs,the addition of anchoring joints,the optimization of grouting slurry and grouting sequence,the construction progress of anchor cable is accelerated and the construction quality is guaranteed.It can be used for reference for similar projects.
