Abstract
本发明公开了一种让压型约束砼拱架高强立体支护体系,其主要由约束砼拱架、让压节点、纵向梁、锚杆或锚索组成。其中,约束砼拱架为与巷道形状一致的封闭式结构,由约束砼通过套筒和让压节点连接组合而成,其间隔一定距离布置,并通过纵向梁连接;锚杆或锚索穿过纵向梁锚入岩层中,并施加预应力,对围岩形成挤压作用;拱架通过纵向梁与锚杆或锚索成为一个整体结构,其共同作用形成空间立体支护体系。本发明适用于深部软岩地下硐巷等地下工程支护,具有支护强度高、稳定性好、受力合理等优点并具有让压功能,能有效控制硐巷围岩的稳定性。
The invention discloses a high-strength three-dimensional support system for a yield-type constrained concrete arch, which is mainly composed of a restrained concrete arch, yield nodes, longitudinal beams, anchor rods or anchor cables. Among them, the constrained concrete arch frame is a closed structure consistent with the shape of the roadway, which is composed of constrained concrete connected through sleeves and yielding nodes, arranged at a certain distance and connected by longitudinal beams; anchor rods or anchor cables pass through The longitudinal beams are anchored into the rock formation and prestressed to form a compression effect on the surrounding rock; the arch frame forms an integral structure through the longitudinal beams and anchor rods or anchor cables, and their joint action forms a three-dimensional support system in space. The invention is suitable for underground engineering support such as underground tunnels in deep soft rock, and has the advantages of high support strength, good stability, reasonable stress, etc., and has a pressure-relieving function, and can effectively control the stability of surrounding rocks in tunnels.
