本文结合工程实例,提出了以竖井废弃钢丝绳为绳索材料,采用两端高标号水泥砂浆粘结,中段低标号水泥砂浆填充的半柔性长锚索结构以及相应的施工工艺,并以长锚素加固方式来解决顶板稳定性问题。
Based on the engineering examples, a semi-flexible long-anchor structure filled with low-grade cement mortar with high-end cement mortar and correspondingly construction technology was proposed. The abandoned steel wire rope was used as the rope material, Way to solve the roof stability problems.
