摘要
根据河北某铁矿井下生产技术和充填方式,对原有空心砖砌筑充填挡墙进行工艺改造。采用编织袋填装充填料浆代替空心砖,通过力学分析以及厚度计算确定一次充填高度和挡墙厚度,形成一套完整的充填挡墙快速砌筑工艺。生产实践表明:编织袋填装充填料浆砌筑充填挡墙墙体厚度2.5 m时即可满足生产要求,且滤水性能优于空心砖砌筑的充填挡墙,充填效率提高、充填体强度增加。
According to production technology and filling method in an iron mine in Hebei,process reformation is conducted about backfilled retaining wall made by hollow brick. Bags filling slurry is instead of hollow bricks. The height of filling and the thickness of backfilled retaining wall are defined by mechanical analysis and thickness calculation. A complete quick masonry technique of backfilled retaining wall is formed. Practice shows that： the thickness of backfilled retaining wall with bags filling slurry 2. 5 m can meet the production requirements. Its drainage performance is better than that of the backfilled retaining wall with hollow brick,and its efficiency of filling and the strength of filling body are higher.
