管片壁后填充材料与管片姿态对比研究

摘要

以神华神东补连塔煤矿二号辅运平硐工程为基础，在混凝土管片壁后分别填充混凝土、豆粒石、单液浆、双液浆等四种材料后，对管片的沉降和扭转进行了对比研究。结果表明填充材料为混凝土时管片的姿态控制最佳。%Based on the second subsidiary transport adit project of Shenhua Shendong Bulianta coal mine,this paper stud-ies the segment settlement and torsion after the concrete segments are filled with concrete,pea gravel,single-liquid grou-ting,double-liquid grouting respectively.The results show that the controlling of segment attitude is the best when filled by the concrete.
